Driving systems
Overview of driving systems
The vehicle's driving systems are described on the following pages:
-
Cruise control, Distronic* and Speedtronic, which are used to control the speed of the vehicle
-
HOLD, which makes pulling away easier, particularly on steep uphill gradients
-
Vehicle level setting and AIRMATIC DC*, which are used to adjust the vehicle's suspension system
-
4*MATIC (permanent four-wheel drive), for optimum traction
-
Parktronic*, which assists you in parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP®, EBV (electronic brake-power distribution) and ADAPTIVE BRAKE driving safety systems are described in the "Driving safety systems" section 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 or towing a trailer, you must shift to a lower gear in good time or select shift range 1, 2 or 3 in vehicles with automatic transmission*. 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 cruise control is activated, the segments from the set speed to the maximum speed light up in the multi-function display.
 |
 | Segments |

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.
|
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 .
|
| |
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.
Vehicles with manual transmission:
-
Always drive at adequate, but not excessive, engine speeds.
-
Change gear in good time.
-
If possible, do not change down several gears at a time.
|
Selecting 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 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.
|
| |
|
Deceleration of the vehicle by means of the cruise control lever is assisted by automatic application of the brakes.
Vehicles with automatic transmission*:
On long downhill gradients, the automatic transmission shifts down as a further measure.
|
Making fine adjustments in 1 km/h increments
| |
Briefly press the cruise control lever 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 depress the parking brake
-
you are driving at less than 30 km/h
-
ESP® is intervening or you deactivate ESP®
-
you move the selector lever to N in vehicles with automatic transmission* 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 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 or towing a trailer, you must select shift range
1, 2 or 3. 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.
|
| 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 180 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.
|

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 adjusted. You will be driving at the speed
you determine by the position of the accelerator pedal.

the distance to the vehicle in front if
necessary.
|
Distance
warning function
Even if Distronic is
deactivated, this function warns you at speeds above 30 km/h
if:
-
the distance to the
vehicle in front is too short for the speed you are driving at for several
seconds. The
distance warning lamp in the instrument cluster then lights up.
-
you are approaching
a vehicle in front at too great a speed. You then hear an intermittent warning
tone, and the
distance warning lamp in the instrument cluster lights up.
You must apply the
brakes yourself in order to maintain the correct distance to the vehicle and to
avoid a collision.
| Risk of accident |
|
Be especially observant of traffic conditions when the distance warning lamp in the instrument cluster lights up or an intermittent warning tone sounds.
Brake or take evasive action as necessary.
|
| |
|
Distronic does not
always clearly recognise complex road and traffic conditions. You may then
receive a false distance warning tone or none at all.

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,
going into and coming out of 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.
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 or towing a trailer, you must shift to a lower gear in good time or
select shift range 1, 2 or 3 in vehicles with
automatic transmission*. 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 tyres
more
| 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
With the cruise
control lever, you can operate cruise control, Distronic* and variable Speedtronic.
The LIM indicator lamp

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 driver's door is closed
-
the parking brake is not applied
-
the bonnet is closed
-
on vehicles with automatic transmission*, the selector lever is in position D, R or N
Activating HOLD
| |
Make sure that the activation conditions are met.
|
| |
Depress the brake.
|
| |
Depress the brake again quickly until HOLD appears in the display.
|
| |
HOLD is activated. You can release the brake pedal.
|
| |
|
If depressing the brake pedal the first time does not activate HOLD, wait briefly and then try again.
|
| Risk of accident |
|
The vehicle's brakes are applied when HOLD is activated. For this reason, deactivate HOLD if the vehicle is to be set in motion by other means (e.g. in a car wash or by towing).
|
Deactivating HOLD
HOLD is deactivated if:
-
you accelerate. On vehicles with automatic transmission*, only if the selector lever is in position D or R.
-
the selector lever is moved to P on vehicles with automatic transmission*
-
you release the brakes completely and apply them again with a certain amount of pressure until the HOLD message in the multi-function display goes out
| Risk of accident |
|
Never get out of the vehicle when HOLD is activated.
HOLD must never be operated or deactivated by a passenger or from outside the vehicle.
HOLD does not replace the parking brake and must not be used for parking.
The HOLD braking effect is cancelled and the vehicle can start moving if:
-
HOLD is deactivated by depressing the accelerator pedal or the brake pedal
-
there is a malfunction in the system or an interruption in the power supply, e.g. battery failure
-
the electrical system in the engine compartment, the battery or the fuses are tampered with
-
the battery is disconnected
|
| Risk of accident |
|
If you wish to leave the vehicle or park it, deactivate HOLD and secure the vehicle against rolling away.
|
You will see a warning message in the multi-function display if HOLD is activated and:

| |
Move the selector lever to P to prevent the vehicle from rolling away.
|
| |
HOLD is deactivated. The warning message in the multi-function display goes out.
|
A horn will also sound at regular intervals if HOLD is activated and you:
The horn draws your attention to the fact that the vehicle has been parked while HOLD is still activated. The sound becomes louder if you attempt to lock the vehicle. The vehicle is not locked until HOLD is deactivated.
| |
|
If the ignition has been switched off, the engine cannot be restarted until HOLD is deactivated.
|
If there is a fault in the system or power supply while HOLD is activated, the Brake immediately message appears in the multi-function display. Immediately depress the brake firmly until the warning message disappears from the multi-function display, or in vehicles with automatic transmission*, move the selector lever to P. This deactivates HOLD.

Multi-function
display
A
message appears in the multi-function display for approximately five seconds
once you have selected a damping program, for example:
4MATIC* (permanent four-wheel drive)
4MATIC
ensures that all four wheels are permanently driven. Together with ESP®, it
improves the traction of your vehicle whenever a drive wheel spins due to
insufficient grip.
| Risk of accident |
|
4MATIC cannot reduce the risk of an accident if you drive too fast.
If a drive wheel spins due to insufficient grip:
-
Only depress the accelerator pedal as far as necessary when pulling away.
-
Accelerate less when driving.
-
Adapt your driving style to suit road and traffic conditions.
|
| |
|
In wintry driving
conditions, the maximum effect of 4MATIC can only be achieved if you use winter
tyres (M+S tyres), with snow chains if necessary.
|
Parktronic*
| Risk of accident |
|
Parktronic is only an aid and may not detect all obstacles. It is not a substitute for attentive driving.
You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and manoeuvring. You could otherwise endanger yourself and others.
|
| Risk of injury |
|
Make sure that no persons or animals are in the manoeuvring range. Otherwise, they could be injured.
|
Parktronic is an electronic parking aid. It indicates visually and audibly the distance between your vehicle and an object.
Parktronic is automatically activated when you switch on the ignition and release the parking brake.
Parktronic is deactivated at speeds above 18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.

Range of the sensors
The sensors must be free of dirt, ice and slush, otherwise they may not function correctly. Clean the sensors regularly, taking care not to scratch or damage them.

Pay particular attention to objects above or below the sensors when parking, such as flower pots or trailer towbars. Parktronic does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects.
Ultrasonic sources such as an automatic car wash, a lorry's compressed-air brakes or a pneumatic drill could cause Parktronic to malfunction.

If there is an obstacle within this range, all warning displays light up and a tone sounds. If the distance falls below the minimum clearance, it may no longer be shown.
Warning displays
The warning displays show the distance between the sensors and the obstacle. The warning display for the front area is located on the dashboard above the centre air vents. The warning display for the rear area is in the roof trim at the rear.
