Driving systems
Your vehicle's driving systems are described on the following pages:
-
Cruise control* and Speedtronic* which you can use to control the speed of the vehicle
-
Parktronic* and active parking assist*, which assist you when parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP® and Steer Assist driving safety systems are described in the "Driving safety systems" section more.
Cruise control*
Cruise control maintains a constant road speed for you. You must select a low gear in good time on long and steep downhill gradients, especially if the vehicle is laden or towing a trailer. In this way 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 |
|
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.
|
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
|

|
Speedtronic*
Speedtronic is used to make sure that you do not exceed a stored
speed. You must select a low gear in good time on long and steep downhill
gradients, especially if the vehicle is laden or towing a trailer. In this way
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 |
|
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.

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 handbrake.
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.
 |
| Sensors in the front 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 more.

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.
 |
| Left-hand side of the vehicle |
| Right-hand side of the vehicle |
| Indicator segments |
|
Front area warning display
The warning display for each side of the vehicle is divided into five yellow and two red segments. Parktronic is operational if yellow indicator segments light up.
The gear lever or selector lever position* determines which warning display is active:
Manual transmission:
|

One or more segments light up as the vehicle approaches an obstacle, depending on the vehicle's distance from the obstacle.
-
Front area: from the sixth segment onwards, you will hear an intermittent warning tone, from the seventh segment onwards, you will hear a continuous warning tone for a maximum of two seconds. You have reached the minimum distance.
-
Rear area: from the sixth segment onwards, you will hear an intermittent warning tone. At the seventh segment, you will hear a continuous warning tone for a maximum of two seconds. You have reached the minimum distance. The continuous warning tone is muted immediately if you deselect reverse gear on vehicles with manual transmission or if you select D or P on vehicles with AUTOTRONIC*.
Deactivating/activating Parktronic
 |
| To deactivate/activate Parktronic |
| Indicator lamp |
|
If indicator lamp is on, Parktronic is deactivated.
| |
|
Parktronic is automatically activated when you turn the key to position 2 in the ignition lock.
|
Trailer towing*
Parktronic is deactivated for the rear area when you establish an electrical connection between your vehicle and the trailer.
| |
|
Remove the detachable trailer coupling if it is no longer required. Parktronic measures the minimum detection range to an obstacle from the bumper, not the ball coupling.
|
Active parking assist*
Active parking
assist is an electronic parking aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle. A suitable parking space is
indicated by the parking symbol. Active steering intervention can assist you
during parking. You may also use Parktronic
more.
When Parktronic is switched off, active parking assist is also unavailable.
| Risk of accident |
|
Active parking assist is merely an aid and may sometimes recommend parking spaces that are not suitable for parking. These might be, for example, spaces where parking is prohibited, driveways, unsuitable surfaces, etc.
Active parking assist measures the parking space as you drive past it. Any later changes to the parking space are not taken into account. This may be the case, for instance, when the vehicle parked in front of or behind the space changes its position or when an obstacle is moved into the parking space.
Active parking assist does not relieve you of the responsibility of paying attention. If you rely solely on active parking assist, you could cause an accident and injure yourself and others.
You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and manoeuvring.
|
| Risk of accident |
|
Objects located above the height range of active parking assist will not be detected when the parking space is measured. These are not taken into account when the parking procedure is calculated, e. g. overhanging loads, tail sections or loading ramps of goods vehicles. In some circumstances, active parking assist might therefore guide you into the parking space too early. This may lead to a collision. For this reason, you should avoid using active parking assist in such situations.
|
| Risk of accident |
|
The front of the vehicle will veer out in the direction of the oncoming traffic during the parking operation. In some cases the vehicle will also take you onto sections of the oncoming lane during the parking procedure.
You are responsible for safety at all times and must pay attention to any road users approaching or passing. Stop the vehicle if necessary or cancel the active parking assist parking procedure.
|
| Risk of injury |
|
Make sure that no persons or animals are in the manoeuvring range. Otherwise, they could be injured.
|
Use active parking assist for
parking spaces
-
that are parallel
to the direction of travel
-
that are on
straight roads, not bends
-
that are on the
same level as the road, i.e. not on the pavement, for example;
Parking tips:
-
On narrow roads,
drive as close to the parking space as possible.
-
Parking spaces
which are littered, overgrown or partially occupied by trailer towbars might
not be identified properly.
-
Snowfall or heavy
rain may lead to a parking space being measured inaccurately.
-
Pay attention to
the Parktronic warning messages during the parking procedure
more.
-
If you shift into
forward gear early, you can influence the steering characteristics of active
parking assist. This will enable you to align the vehicle in the parking space
yourself.
-
You can intervene
in the steering procedure to correct it at any time. active parking assist will
then be cancelled.
-
When transporting a
load which protrudes from your vehicle you should not use active parking
assist.
-
Never use active
parking assist when snow chains or an emergency spare wheel* are fitted.
-
Make sure that the
tyre pressures are always correct. This has a direct influence on the parking
characteristics of the vehicle.
-
The way your
vehicle is positioned in the parking space after parking is dependent on
various factors. These include the position and shape of the vehicles parked in
front and behind it and the conditions of the location. In some cases, active
parking assist may guide you too far into a parking space, or not far enough
into it. In some cases it may also lead you across or onto the kerb. If
necessary, you should abort the parking procedure with active parking
assist.
| |
|
When unavoidable, you should drive over obstacles such as kerbs slowly and not at a sharp angle. Otherwise you may damage the wheel rims or tyres.
|
Detecting
parking spaces
Active parking
assist is switched on automatically when driving forwards. The system is
operational at speeds of up to approximately 35 km/h. While in
operation, the system independently locates and measures parking spaces on both
sides of the vehicle. When driving at speeds below 16 km/h, you
will see the parking symbol as a status indicator in the instrument cluster.
Active parking assist only displays parking spaces on the front-passenger side
as standard. Parking spaces on the driver's side are displayed as soon as the
turn signal on the driver's side is activated. If you wish to park in a space
on the driver's side, the indicator on the driver's side must remain on. It
must remain switched on until you acknowledge the use of active parking assist
by pressing the 
button on the multi-function steering wheel.
When a parking
space has been detected, an arrow towards the right or the left also
appears.
 |
| Detected parking space on the
left |
| Parking symbol |

Example:
Parking space detected
Active parking assist will
only detect parking spaces:
-
that are parallel
to the direction of travel
-
that are at least
1.5 m wide
-
that are at least
1.3 m longer than your vehicle
A parking space is
displayed while you are driving past it, and until you are approx. 15 m
away from it.
