In some countries, Park Assist can assist the driver with an automatic braking intervention in certain
situations
Depending on the vehicle equipment and certain conditions, e.g. weather, load or inclination of the
vehicle, Park Assist can automatically brake the vehicle before an obstacle. Following this
intervention, the driver must depress the brake pedal.
The parking manoeuvre is ended if an automatic braking intervention occurs.

Critical situation. Do not drive on!Possible critical situation.
Detection of a critical situation can also take place acoustically:
A warning signal will sound and a text message will be displayed in the instrument cluster for
vehicles without Park Distance Control.
In vehicles with Park Distance Control, an acoustic signal will sound with the continuous tone of Park
Distance Control. If the Park Distance Control is deactivated, no warning can be given to the driver
and the Rear Traffic Alert system will also be switched off temporarily.
If there is a system fault in the scanned area, the indicator lamp will light up yellow on the
instrument cluster display.
Automatic braking intervention to minimise damage
If Rear Traffic Alert detects an approaching road user and the driver has not pressed the brake, the
system can brake automatically.
Automatic braking intervention is activated when reversing at speeds of between 1 km/h (1
mph). The vehicle is held stationary for up to two seconds after vehicle standstill has been
detected.
After automatic braking intervention is activated to prevent damage to the vehicle, the system
requires approximately ten seconds before it can activate another automatic braking intervention.
Automatic braking intervention can be interrupted by pressing the accelerator or brake pedal
sharply and taking control of the vehicle.
Automatic deactivation
Rear Traffic Alert is deactivated automatically and cannot be switched on if the factory-fitted towing
bracket is electrically connected to a trailer or similar Notes on towing a trailer
electrically connected to the vehicle and the driver pulls away, a text message appears in the
instrument cluster display to inform the driver that Rear Traffic Alert has been deactivated. Rear
Traffic Alert will be automatically activated again when the trailer has been unhitched from the
vehicle. This applies if the functions were previously activated. Rear Traffic Alert must be switched
off manually for trailer towing if a non-factory-fitted towing bracket is used.
WARNING
The intelligent Rear Traffic Alert technology cannot overcome the laws of physics, and functions only
within the limits of the system. Do not let the assistance function of Rear Traffic Alert tempt you to
take any safety risks while driving. The system is not a substitute for the full concentration of the
driver.
busy roads or across several lanes.
Always pay attention to the area around the vehicle, since cyclists and pedestrians are often not
reliably detected, for example.
The Rear Traffic Alert will not always independently bring the vehicle to a complete stop.
Brake support systems
Information on brake support systems
The vehicle is fitted with brake support systems. The systems can support the driver in critical driving
or braking situations. Brake support systems cannot overcome the limits of physics and cannot
always keep the vehicle under control in every single critical driving or braking situation. The driver is
responsible for driving safety
Driving with brake support systems
The brake support systems work when the engine is running. They do not need to be operated
separately.
The brake pedal may pulsate or noises may occur while the brake support systems are regulating.
Continue to apply the necessary amount of brake pressure. Apply the necessary pressure to the
brake pedal consistently. If necessary, steer the vehicle while the brake pedal is depressed.
Electronic Stability Control (ESC)
ESC helps to reduce the risk of skidding and to improve driving stability in certain driving situations
ESC is always switched on.
Traction control system (TCS)
The TCS reduces the drive output if wheelspin occurs and adapts the drive output to suit road
surface conditions Troubleshooting
hills.
With some equipment levels, the TCS can be switched off in exceptional circumstances Switching
the TCS on and off
Anti-lock brake system (ABS)
The anti-lock brake system can prevent the wheels from locking when the brakes are applied up until
the point where the vehicle is nearly stationary and assists the driver in steering the vehicle and
keeping it under control Troubleshooting
Brake assist system
The brake assist system can help to reduce the stopping distance. The brake assist system reinforces
the braking force when the driver depresses the brake pedal quickly in an emergency situation.
If you reduce the pressure on the brake pedal, the brake assist system will switch off the brake
servo.
EDL brakes a spinning wheel automatically and distributes the drive force to the other drive wheels.
The EDL switches off automatically under unusually heavy loads to prevent the brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS improves traction in order to keep the vehicle on its intended course.
Automatic Post-Collision Braking System
In the event of a collision, the Automatic Post-Collision Braking System can help the driver to reduce
the risk of skidding, and the danger of secondary collisions, through automatic braking.
The Automatic Post-Collision Braking System functions only for collisions that are detected as a
collision by the airbag control unit.
The vehicle is braked automatically if the required systems have not been damaged in the collision
and have remained functional.
The following actions override automatic braking in the event of a collision:
When the driver depresses the accelerator.
When the brake pressure transmitted through the depressed brake pedal is greater than the brake
pressure provided by the system.
WARNING
The intelligent technology used in brake support systems cannot overcome the laws of physics, and
functions only within the limits of the systems. Driving fast on icy, slippery or wet roads can lead to a
loss of control of the vehicle and could cause serious injury to the driver and passengers.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions. Do
not let the extra safety afforded by the brake support systems ABS, BAS, EDL, TCS and ESC tempt you
into taking any risks when driving.
The brake support systems cannot overcome the laws of physics. Slippery and wet roads will remain
dangerous, even when the ESC and other systems are active.
Driving too fast on wet roads can cause the wheels to lose contact with the road surface and
aquaplane. The vehicle cannot be braked, steered or controlled once it has lost contact with the
road surface.
Brake support systems cannot prevent an accident if, for example, you are driving too close to the
vehicle in front or are driving too fast for the individual situation.
Although the brake support systems are very effective and can help to control the vehicle in difficult
driving situations, please always remember that the driving stability of the vehicle depends on the
tyre grip.
wheels can spin even when brake support systems are active, and this can lead to a loss of control of
the vehicle.
WARNING
The effectiveness of ESC can be reduced considerably if other components and systems which affect
driving dynamics are not serviced properly or are not functioning properly. This also applies, but not
exclusively, to the brakes, tyres and other named systems.
Please always bear in mind that modifications and changes to the vehicle can affect the way brake
support systems operate.
Alterations to the suspension or the use of non-approved wheel and tyre combinations can affect
the function of brake support systems and reduce their effectiveness.
Suitable tyres support the effectiveness of ESC.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus cause
accidents and serious injuries.
Never switch the engine or ignition off while the vehicle is in motion.
If the brake servo does not function or the vehicle is being towed, the brake pedal will have to be
depressed more forcefully as the braking distance will be increased due to the lack of assistance for
the brake system.
Switching the TCS on and off
Switch off the traction control system (TCS) if the vehicle does not have sufficient traction:
When driving in deep snow or on loose surfaces.
When rocking the vehicle free if it is stuck.
Then switch on TCS again.
Switching TCS on and off
TCS can be switched off and on in the Infotainment system Infotainment system controls and
displays
When the TCS is switched off, the yellow indicator lamp lights up on the instrument cluster
display.
As soon as the TCS starts regulating, the indicator lamp flashes yellow.

The brake support systems make noises
Noises may be heard when the brake support systems are performing control interventions.
Unexpected reduction in engine power
Faults can occur in the ESC and TCS systems if the four wheels have different types of tyres.
Any differences in the rolling radius of the tyres can cause the system to reduce engine power
unexpectedly.
WARNING
If the brake system warning lamp lights up together with the ABS indicator lamp , the ABS
control function may have failed. This can cause the rear wheels to lock quickly when you brake.
Locked rear wheels can lead to a loss of control of the vehicle. If possible, reduce your speed and
drive carefully at low speed to the nearest qualified workshop in order to have the brake system
tested. Avoid sudden braking and driving manoeuvres on the way.
If the ABS indicator lamp does not go out or comes on while the vehicle is in motion, ABS is not
working properly. The vehicle can be stopped using the normal brakes only (without the anti-lock
brake system). The protection provided by the anti-lock brake system is no longer available. Go to a
qualified workshop as soon as possible.
