Automatic braking intervention
Trailer Assist helps the driver by initiating an automatic braking intervention in certain situations.
The driver is responsible for braking in time ⇒.
An automatic braking intervention may occur and the function may be cancelled in the following
situations:
•If a certain speed is exceeded.
•If the driver takes hold of the steering wheel. The vehicle is automatically braked to standstill.
•If the button is pressed while manoeuvring or the driver door is opened.
The exterior mirrors cannot be adjusted while Trailer Assist is active. The stored exterior
mirror setting can be activated ⇒ Mirrors.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
No camera visibility, error message, system switches itself off
•Clean the camera or remove stickers or accessories from the camera ⇒ Caring for and cleaning
the vehicle exterior.
•Check whether any damage is visible.
The system is not responding as expected
•The camera is dirty ⇒ Caring for and cleaning the vehicle exterior. The camera visibility may be
impaired by dirt and snow or also residue from cleaning agents or coatings.
•The system requirements must be met ⇒ Prerequisites.
•The camera is covered by water.
•The vehicle is damaged in the area around the camera, e.g. caused by parking collisions.
•The detection range of the camera is blocked by add-on parts, e.g. bicycle carriers.
•Changes have been made to the paintwork around the camera or the construction has been
modified, e.g. vehicle front end or the running gear.
Response to all circumstances
•Switch off the system temporarily.
•Check whether any of the causes described below apply.
•You can switch the system back on again once you have rectified the cause of the problem.
•If the system still fails to respond as expected, have the system checked by a qualified
workshop.
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.
Fast steering wheel movements can cause serious injury.
•During the manoeuvring operation, do not reach for the steering wheel until prompted
to do so by the system.
•Exception: if a dangerous situation occurs, intervene and take over the steering.
WARNING
Do not let the automatic braking intervention tempt you to take any risks while driving, as
this can cause accidents. The system is not a substitute for the full concentration of the
driver.
•Trailer Assist has system-related limitations. In some situations, the automatic braking
intervention function is only able to intervene in a limited way or not at all.
•You should always be prepared to brake the vehicle yourself.
•The automatic braking intervention is ended after approximately 1.5 seconds at vehicle
standstill. Depress the brake pedal of the vehicle yourself following the automatic
braking intervention.
WARNING
Electronic Stability Control (ESCyf
ESC helps to reduce the risk of skidding and to improve driving stability in certain driving situations
⇒.
Depending on the vehicle equipment, ESC can be switched to a Sport mode ⇒ Switching TCS on
and off.
When ESC is regulating, the yellow indicator lamp is shown on the instrument cluster display.
Traction control system (TCSyf
The TCS reduces the drive output if wheelspin occurs and adapts the output to suit road surface
conditions. The TCS makes it easier to pull away, accelerate and drive up hills.
Depending on the vehicle equipment, the TCS can be switched off in exceptional circumstances
⇒ Switching TCS on and off.
When the TCS is regulating, the yellow indicator lamp is shown on the instrument cluster
display.
Anti-lock brake system
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.
Brake assist system
The brake assist system can help to reduce the stopping distance. The brake assist system
reinforces brake pressure when the driver depresses the brake pedal quickly in an emergency
situation.
Do not reduce the pressure on the brake pedal when the brake assist system is regulating. If you
reduce the pressure on the brake pedal, the brake assist system will switch off the brake servo.
Electronic differential lock (EDL and XDSyf
EDL brakes the wheel that has lost traction and distributes the driving force to the other drive
wheels.
The EDL switches off automatically under unusually heavy loads to prevent the disc brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS applies pressure to the brake of the wheel on the inside of the bend. This will improve traction,
helping the vehicle to remain in the required lane longer.
Automatic Post-Collision Braking System
In the event of an accident, 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 in front, side and rear collisions when
the airbag control unit detects a corresponding trigger threshold during the accident.
The ESC brakes the vehicle automatically, provided that the hydraulic braking system, the ESC and
the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
•When the driver depresses the accelerator. No automatic braking occurs.
•When the brake pressure transmitted through the depressed brake pedal is greater than the
brake pressure provided by the system. The vehicle is braked manually.
Always ensure that the ventilation openings between the rear window and the stowage area
are uncovered to allow stale air to escape from the vehicle.

Loose objects may be flung through the vehicle interior in the event of a sudden driving or
braking manoeuvre. This can cause serious injury and can also lead to loss of control of
the vehicle.
•Do not stow any pets or any hard, heavy or sharp objects in the vehicle's open stowage
areas, on the dash panel, on the shelf behind the rear seats, or in items of clothing and
bags in the vehicle interior.
•Always keep stowage compartments closed while the vehicle is in motion.
WARNING
Objects in the driver footwell can hinder pedal operation. This can lead to loss of control
of the vehicle and increase the risk of serious injury.
•Please ensure that all pedals can always be operated without any hindrance.
•The floor mats must always be properly secured in the footwell.
•No additional floor mats or other floor coverings should be placed over the fitted floor
mat.
•Ensure that no objects can enter the driver footwell while the vehicle is in motion.
•If there are any objects in the footwell, remove them when the vehicle is parked.
WARNING
Cigarette lighters in the vehicle could be damaged or accidentally lit. This could lead to
serious burns and other injuries.
•Before adjusting the seats, always ensure that there is no lighter on or near the
moveable parts of the seat.
•Before closing stowage areas or compartments always ensure that there is no lighter
in the way.
•Never stow lighters in stowage areas, compartments or on other surfaces in the
vehicle. High surface temperatures, especially in summer, may cause cigarette lighters
to self-ignite.
WARNING
•Hard objects could rub against the wires of the heating element in the rear window and
cause damage.
•Do not stow any temperature-sensitive objects, food or medicines inside the vehicle.
Hot and cold temperatures could damage them or render them unusable.
•Objects stored in the vehicle that are made from transparent materials, such as
glasses, magnifying glasses or transparent suction cups on the windows, can
concentrate the sun's rays and thus cause damage to the vehicle.
