Driving systems
Overview of driving systems
The vehicle's driving systems are described on the following pages:
-
Cruise control, Distronic*, Distronic Plus* and Speedtronic, which are used to control the speed of the vehicle
-
HOLD, which makes pulling away easier, particularly on steep uphill gradients
-
Active Body Control* (ABC), which is used to adjust the vehicle's suspension system
-
4*MATIC (permanent four-wheel drive), for optimum traction
-
Parktronic and Park Assist*, which assist you when parking and manoeuvring
-
Reversing camera*, which assists you when parking and manoeuvring
-
Night View Assist*, which assists you when parking in the dark
-
Parking Guidance*, which assists you when looking for a parking space and assists you when parking
-
Blindspot-Assist*, which assists you when changing lanes
The ABS, BAS, BAS PLUS*, ESP, EBV and ADAPTIVE BRAKE driving safety systems, the distance warning system* and the PRE-SAFE brake* are described in the "Driving safety systems" chapter more.
Cruise control
Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must select shift range 1, 2 or 3 in good time. By doing so you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
 | Risk of accident |
|
Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid.
|
Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 30 km/h.
| Risk of accident |
|
Cruise control cannot take account of road and traffic conditions.
Always pay attention to traffic conditions even when
cruise control is activated.
Cruise control is only an aid designed to assist driving. You are responsible for the vehicle's speed and for braking in good time.
|
| Risk of accident |
|
Do not use
cruise control:
-
in road and traffic conditions which do not allow you to maintain a constant speed (e.g. heavy traffic or winding roads). You could otherwise cause an accident.
-
on slippery roads. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid.
-
when there is poor visibility, e.g. due to fog, heavy rain or snow
|
Cruise control display in the speedometer
When you switch on cruise control, the stored speed appears in the multi-function display for five seconds and is then indicated in the speedometer by a triangle. The speedometer dial lights up between the set speed and the maximum speed.
Cruise control lever
You can operate cruise control and variable Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control lever indicates which system you have selected:
 |
 | To store the current speed or a higher speed |
 | LIM indicator lamp |
 | To select the current or last stored speed |
 | To store the current speed or a lower speed |
 | To switch between cruise control and variable Speedtronic |
 | Deactivating cruise control |
|
Selecting cruise control
 |
Check whether LIM indicator lamp is off.
If it is off, cruise control is already selected.
If it is not, press the cruise control lever in the direction of arrow .
|
| |
LIM indicator lamp in the cruise control lever goes out. Cruise control is selected.
|
| Risk of accident |
|
The brake pedal is retracted when cruise control brakes. Do not restrict the freedom of movement of the pedal in any way.
-
Do not put any objects in the footwell.
-
Ensure that floor mats and carpets are fixed securely.
-
Do not place your foot under the brake pedal as it could become trapped.
You could otherwise cause an accident and injure yourself and others.
|
Storing and maintaining the current speed
You can store the current speed if you are driving faster than 30 km/h and ESP® is activated more.
| |
Accelerate the vehicle to the desired speed.
|
| |
Briefly press the cruise control lever up or down to the pressure point.
|
| |
Remove your foot from the accelerator pedal.
|
| |
Cruise control is activated. The vehicle automatically maintains the stored speed.
|
 | |
|
Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Cruise control maintains the stored speed on downhill gradients by automatically applying the brakes.
|
To select the current or last stored speed
| Risk of accident |
|
Only select a stored speed if you know what that speed is and whether it is suitable for the current situation. Otherwise, sudden acceleration or braking could endanger you or others.
|
| |
Briefly pull the cruise control lever towards you .
|
| |
Remove your foot from the accelerator pedal.
|
| |
The first time cruise control is activated it stores the current speed or regulates the speed of the vehicle to the previously stored speed.
|
Setting a speed
| |
Press the cruise control lever to the pressure point, up for a higher speed or down for a lower speed.
|
| |
Keep the
cruise control lever pressed until the desired speed is reached.
|
| |
Release the cruise control lever.
|
| |
The new speed is stored.
|
| |
|
Cruise control is not deactivated if you depress the accelerator pedal. For example, if you accelerate briefly to overtake, cruise control adjusts the vehicle's speed to the last speed stored after you have finished overtaking.
|
Making fine adjustments in 1 km/h increments
| |
Briefly press the cruise control lever to the pressure point, up for a higher speed or down for a lower speed.
|
| |
The last speed stored is increased or reduced.
|
Making adjustments in 10 km/h increments
| |
Briefly press the cruise control lever beyond the pressure point, up for a higher speed or down for a lower speed.
|
| |
The last speed stored is increased or reduced.
|
Deactivating cruise control
There are several ways to deactivate cruise control:
| |
Briefly press the cruise control lever forwards .
|
or
| |
Brake.
|
or
| |
Briefly press the cruise control lever in the direction of arrow .
|
| |
Variable Speedtronic
is selected. LIM indicator lamp in the cruise control lever lights up.
|
Cruise control is automatically deactivated if, for example:
-
you engage the electric parking brake
-
you are driving at less than 30 km/h
-
ESP® is intervening or you deactivate ESP®
-
you shift the automatic transmission to N while driving
If cruise control is deactivated, you will hear a warning tone. You will see the Cruise control off message in the multi-function display for approximately five seconds.
| |
|
The last speed stored is cleared when you switch off the engine.
|
Distronic*
| |
|
Distronic is only available for certain countries.
|
Distronic regulates the speed and automatically maintains the distance to the vehicle in front. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must select shift range 1, 2 or 3 in good time. By doing so you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
| Risk of accident |
|
The brake pedal is retracted when Distronic brakes. Do not restrict the movement of the pedal in any way.
-
Do not put any objects in the footwell.
-
Ensure that floor mats and carpets are fixed securely.
-
Do not place your foot under the brake pedal as it could become trapped.
You could otherwise cause an accident and injure yourself and others.
|
| Risk of accident |
|
Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid.
|
| Risk of accident |
|
Distronic is only an aid designed to assist driving. The driver remains fully responsible for the vehicle's distance from other vehicles, the vehicle's speed and braking in good time.
Distronic does not react to:
Distronic may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. Therefore, always pay attention to traffic conditions even when Distronic is activated. Otherwise, you may fail to recognise dangers in time, could cause an accident and injure yourself and others.
|
If a slower-moving vehicle is detected in front, Distronic causes your vehicle to brake and maintain a preset distance to the vehicle in front.
| Risk of accident |
|
Distronic cannot take account of road and traffic conditions. Deactivate, or do not activate, Distronic if it does not detect the vehicle in front, or if it no longer detects it. This is especially the case:
-
before corners
-
on filter lanes
-
when changing to a lane with faster moving traffic
-
in complex driving situations or where lanes are diverted, e.g. at roadworks on a motorway.
Otherwise, Distronic maintains the current speed or accelerates to the set speed.
Distronic cannot take account of weather conditions. Deactivate, or do not activate, Distronic:
-
if the roads are slippery, snow-covered or icy. The wheels could lose their grip under braking or acceleration. The vehicle could start to skid.
-
if the sensors are dirty or there is poor visibility, e.g. due to snow, rain or fog. Distance control may be impaired.
Always pay attention to traffic conditions even when Distronic is activated. Otherwise, you may fail to recognise dangers in time, could cause an accident and injure yourself and others.
|
If there is no vehicle in front, Distronic operates in the same way as cruise control. Distronic functions in the 30 km/h to 200 km/h range.
| Risk of accident |
|
Distronic brakes your vehicle at a maximum of 2 m/s2, depending on its speed. This corresponds to approximately 20% of your vehicle's maximum braking power. You must also apply the brakes yourself if this braking power is not sufficient.
If Distronic detects a risk of collision with a vehicle in front, an intermittent warning tone sounds. In addition, the  distance warning lamp in the instrument cluster lights up. Brake to avoid a collision.
|
Cruise control lever
With the cruise control lever you can operate Distronic and variable Speedtronic.
The LIM indicator lamp on the cruise control lever indicates which system you have selected:
 |
| To store the current speed or a higher speed |
| To adjust the set distance |
| LIM indicator lamp |
| To select the current or last stored speed |
| To store the current speed or a lower speed |
| To switch between Distronic and variable Speedtronic |
 | Deactivating Distronic |
|
Selecting Distronic

|
| |
Briefly press the cruise control lever up or down to the pressure point.
|
| |
Remove your foot from the accelerator pedal.
|
| |
Distronic is activated. The vehicle maintains the stored
speed until the distance to the vehicle in front becomes too small.
|
| |
|
If you do not fully release the accelerator pedal, the DISTRONIC Override message appears in the multi-function display. The distance to a slower-moving vehicle in front will then not be governed. You will be driving at the speed you determine by the position of the accelerator pedal.
|
Setting a speed
| |
Press the cruise control lever to the pressure point, up for a higher speed or down for a lower speed.
|
| |
Keep the
cruise control lever pressed until the desired speed is reached.
|
| |
Release the cruise control lever.
|
| |
The new speed is stored.
|
| |
|

|
| |
Briefly pull the cruise control lever towards you .
|
| |
Remove your foot from the accelerator pedal.
|
| |
Distronic is activated and accepts the current speed if it is activated for the first time, or adjusts the vehicle's speed to the last speed stored.
|
Setting the specified minimum distance for Distronic
You can set the specified minimum distance for Distronic by varying the time span between one and two seconds. This time span determines the distance that Distronic should maintain from the vehicle in front, depending on the road speed. You can read this distance in the multi-function display more.
 |
| To reduce the set distance |
| Thumbwheel |
| To increase the set distance |
|
| |
To increase: turn thumbwheel towards .
|
| |
Distronic then maintains a greater distance between your vehicle and the vehicle in front.
|
| |
To decrease: turn thumbwheel towards .
|
| |
Distronic then maintains a shorter distance between your vehicle and the vehicle in front.
|
| |
|
Make sure that you maintain the minimum distance to the vehicle in front required by law. Adjust the distance to the vehicle in front if necessary.
|

Tips for driving with Distronic
The following contains descriptions of certain road and traffic conditions in which you must be particularly attentive. In such situations, brake if necessary. Distronic is then deactivated.
Cornering, entering and exiting a bend
The ability of Distronic to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or belatedly.
Vehicles travelling on a different line
Distronic may not detect vehicles travelling on a different line. The distance to the vehicle in front will be too short.
Other vehicles changing lane
Distronic has not yet detected the vehicle cutting in. The distance to this vehicle will be too short.
Narrow vehicles
Distronic has not yet detected the vehicle in front on the edge of the carriageway, because of its relatively narrow width. The distance to the vehicle in front will be too short.
Distronic Plus*
| |
|
Distronic Plus is not available in all countries.
|
Distronic Plus regulates the speed and automatically maintains the distance to the vehicle in front. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must select shift range 1, 2 or 3 in good time. By doing so you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.

|
 | |
|
You must deactivate the radar sensor system in certain countries and near radio telescope facilities. Further information can be found in the index under "Radar sensor system".
|
Vehicles with COMAND and navigation system*: you must deactivate the radar sensor system near radio telescope facilities more.
If you want Distronic Plus to assist you, the radar sensor system must be activated and operational.
If there is no vehicle in front, Distronic Plus operates in the same way as cruise control. Distronic Plus functions in the range between 0 km/h and 200 km/h.
Do not use Distronic Plus while driving on roads with steep gradients.
| Risk of accident |
|
Distronic Plus brakes your vehicle at a maximum of 4 m/s2 depending on its speed. This corresponds to approximately 40% of your vehicle's maximum brake force. You must also apply the brakes yourself if this braking power is not sufficient.
If Distronic detects a risk of collision with a vehicle in front, an intermittent warning tone sounds. In addition, the distance warning lamp in the instrument cluster lights up. Brake to avoid a collision.
|
Cruise control lever
With the cruise control lever, you can operate Distronic Plus and variable Speedtronic.
The LIM indicator lamp on the cruise control lever indicates which system you have selected:
|
| To store the current speed or a higher speed |
| To adjust the set distance |
| LIM indicator lamp |
| To select the current or last stored speed |
| To store the current speed or a lower speed |
| To switch between Distronic Plus and variable Speedtronic |

|
Switching on Distronic, storing the current speed and maintaining it
| Risk of accident |
|
The vehicle can be braked when Distronic Plus is activated. For this reason, deactivate Distronic Plus if the vehicle is to be set in motion by other means, e.g. by towing.
|
You cannot activate Distronic Plus under the following circumstances:
-
for two minutes after the engine is started
-
if the engine is not running
-
if you brake during the journey
-
if your vehicle is secured by the electric parking brake
-
if ESP® is deactivated
-
when the selector lever is in position P, R or N
-
if the bonnet is open
-
if the driver's door is open and the driver is not wearing a seat belt
Activating while driving
| |
|
When driving at speeds below 30 km/h, you can only activate Distronic Plus if the vehicle in front has been detected and is shown in the multi-function display. If the vehicle in front is not shown in the multi-function display and is no longer being detected, because it has changed lanes, for example, Distronic Plus is deactivated and you hear a warning tone.
|
| |
|
If you do not fully release the accelerator pedal, the DISTRONIC PLUS override message appears in the multi-function display. The distance to a slower-moving vehicle in front will then not be governed. You will be driving at the speed you determine by the position of the accelerator pedal.
|
Activating when driving towards a stationary vehicle
If the vehicle in front of you is stationary, you can only activate Distronic Plus once your vehicle is stationary as well.
| |
Briefly pull the cruise control lever towards you .
|
| |
Distronic Plus is selected.
|
| |
|
Distronic Plus can only be activated at under 30 km/h if a vehicle in front has been detected. Therefore, the Distronic Plus distance display in the instrument cluster should be activated.
|
| |
|
You can use the cruise control lever to set the stored speed and the thumbwheel on the cruise control lever to set the specified minimum distance more.
|
Pulling away
| |
If the vehicle in front pulls away: remove your foot from the brake pedal.
|
| |
Briefly pull the cruise control lever towards you .
|
or |
| |
Accelerate briefly.
|
| |
Your vehicle pulls away and adapts its speed to that of the vehicle in front.
|
Driving
If there is no vehicle in front, Distronic Plus operates in the same way as cruise control.
If a slower-moving vehicle is detected in front, Distronic Plus causes your vehicle to brake and maintain a preset distance to the vehicle in front.
If Distronic Plus detects a faster-moving vehicle in front, it increases the driving speed, but only up to the stored speed.
| Risk of accident |
|
If you depress the brake, Advanced Distronic is deactivated unless your vehicle is stationary. Advanced Distronic will then no longer brake your vehicle. The driver remains fully responsible for the vehicle's distance from other vehicles, the vehicle's speed and braking in good time.
|
Stopping
| Risk of accident |
|
The Distronic Plus braking effect is cancelled and the vehicle could roll away if:
-
Distronic Plus is deactivated using the cruise control lever
-
you accelerate
-
the system or the power supply is disrupted, e.g. due to battery failure
-
the electrical system in the engine compartment or the fuses have been tampered with
-
the battery is disconnected
|
| Risk of accident |
|
Never get out of the vehicle when Distronic Plus is activated.
Distronic Plus must never be operated or deactivated by a passenger or from outside the vehicle.
Distronic Plus does not replace the electric parking brake and must not be used for parking.
If you wish to leave the vehicle for a short time or park it, deactivate Distronic Plus and use the electric parking brake to secure the vehicle against rolling away.
|
If Distronic Plus detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains stationary and you do not need to depress the brake.
| |
|
After a time, the electric parking brake secures the vehicle and relieves the service brake.
|
| |
|
Depending on the specified minimum distance, your vehicle will come to a standstill about four metres behind the vehicle in front. The specified minimum distance is set by the using the thumbwheel on the cruise-control lever.
|

the vehicle is rolling backwards.
-
the vehicle is near radio telescope facilities: only vehicles with COMAND and a navigation system* more.
If Distronic Plus is deactivated, you will hear a warning tone. You will see the DISTRONIC PLUS off message in the multi-function display for approximately five seconds
If the vehicle has been stopped by Distronic Plus and a malfunction occurs in the system, the Brake immediately message appears in the multi-function display. Depress the brake pedal immediately so that the vehicle does not roll away. Distronic Plus is then deactivated, and the message disappears.
Tips for driving with Distronic Plus
The following contains descriptions of certain road and traffic conditions in which you must be particularly attentive. In such situations, brake if necessary. Distronic Plus is then deactivated.
Cornering, going into and coming out of a bend
The ability of Distronic Plus to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or belatedly.
Vehicles travelling on a different line
Distronic Plus may not detect vehicles travelling on a different line. The distance to the vehicle in front will be too short.
Other vehicles changing lane
Distronic Plus has not detected the vehicle cutting in yet. The distance to this vehicle will be too short.
Narrow vehicles
Distronic Plus has not detected the vehicle in front on the edge of the carriageway yet, because of its relatively narrow width. The distance to the vehicle in front will be too short.
Obstructions and stationary vehicles
Distronic Plus does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, Distronic Plus will not brake for these.
Crossing vehicles
Distronic Plus may detect vehicles that are crossing your lane by mistake. Activating Distronic Plus at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.
Speedtronic
Speedtronic brakes automatically so that you do not exceed the
set speed. On long and steep downhill gradients, especially if the vehicle is
laden, you must select shift range 1, 2 or 3 in good
time. By doing so you will make use of the braking effect of the engine, which
relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. If you need additional braking, depress the brake
pedal repeatedly rather than continuously.
| Risk of accident |
|
Never depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by applying constant slight pedal pressure. This causes the brake system to overheat, increases the braking distance and can lead to the brakes failing completely.
|
| Risk of accident |
|
Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid.
|
You can set a variable or
permanent limit speed:
-
Variable
for speed limits, e.g. in built-up areas
-
Permanent
for long-term speed restrictions, e.g. for driving on winter tyresmore
| Risk of accident |
|
Speedtronic is only an aid designed to assist driving. You are responsible for the vehicle's speed and for braking in good time.
|
| |
|
The speed indicated
in the speedometer may differ slightly from the limit speed stored.
|
Variable
Speedtronic
Use the cruise control lever to operate cruise control or
Distronic*/Distronic
Plus* and variable
Speedtronic.
The LIM indicator lamp
on the cruise control lever indicates which system you have selected:
You can use the
cruise control lever to limit the speed to any speed above
30 km/h while the engine is running.

|
Selecting
variable Speedtronic

Check whether LIM
indicator lamp
is on.
If it is
on, variable Speedtronic is already selected.
If it is not, press
the cruise control lever in the direction of arrow
.
|
| |
LIM indicator lamp
in the cruise
control lever lights up. Variable Speedtronic is
selected.
|
| Risk of accident |
|
If there is a change of drivers, advise the new driver of the limit speed stored.
Only use Speedtronic when you do not have to accelerate suddenly to a speed higher than the stored limit speed allows. You could otherwise cause an accident.
You can only exceed the limit speed stored if you deactivate variable Speedtronic:
It is not possible to deactivate variable Speedtronic by braking.
|
| Risk of injury |
|
Variable Speedtronic brakes automatically in order to avoid exceeding the set speed. As it does so, the brake pedal is depressed. Do not place your foot under the brake pedal as it could become trapped.
|
Storing the
current speed
You can use the
cruise control lever to limit the speed to any speed above
30 km/h while the engine is running.
| |
Briefly press the
cruise control lever up or down
to the pressure
point.
|
| |
The current speed
is stored and shown in the multi-function display.
The speedometer
dial lights up between the start of the scale and the stored
speed.
|
Storing the
current speed or calling up the last stored speed
| Risk of accident |
|
Only select a stored speed if you know what that speed is and whether it is suitable for the current driving and traffic situation. Otherwise, sudden braking could endanger you or others.
|
| |
Briefly pull the
cruise control lever towards you
.

To deactivate
variable Speedtronic
There are several ways to
deactivate variable Speedtronic:
| |
Briefly press the
cruise control lever forwards
.
|
or
| |
Briefly press the
cruise control lever in the direction of arrow
.
|
| |
LIM indicator lamp
in the cruise
control lever goes out. Variable Speedtronic is deactivated.
Cruise control or
Distronic*/Distronic
Plus* is
selected.
|
Variable
Speedtronic is deactivated automatically when you depress the accelerator pedal
beyond the pressure point (kickdown) but only if your current speed does not
differ by more than 20 km/h from the stored speed. You will hear
a warning tone if this is the case.
| Risk of accident |
|
It is not possible to deactivate variable Speedtronic by braking.
|
| |
|
The last speed
stored is cleared when you switch off the engine.
|
Permanent
Speedtronic
| |
|
Permanent
Speedtronic is only available for certain countries.
|
You can use the
on-board computer to limit the speed permanently to a value between 160
km/h (e.g. for driving with winter tyres) and the maximum speed.
Shortly before the
stored speed is reached it is shown in the multi-function display.
Permanent
Speedtronic remains active, even if variable Speedtronic is deactivated.
You cannot exceed
the stored limit speed, even if you depress the accelerator pedal beyond the
pressure point (kickdown).
Setting permanent Speedtronic
HOLD
HOLD relieves the strain on the driver:
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is cancelled and HOLD deactivated when you depress the accelerator pedal to pull away.
Activation conditions
You can activate HOLD if:
-
the vehicle is stationary
-
the engine is running
-
the electric parking brake is released
-
the automatic transmission is in position R, N or D. If the automatic transmission is in position R, the boot lid must be closed
-
the bonnet is closed
-
your seat belt is fastened or you are driving faster than 3 km/h and have not opened the driver's door again
-
you shift the selector lever away from P while the driver's door is closed
Activating HOLD
| |
Make sure that the activation conditions are met.
|
| |
Depress the brake.
|
| |
Depress the brake again quickly until the HOLD display appears in the multi-function display.
|
| |
HOLD is activated. You can release the brake pedal.
