Brake assist systems
Information relating to brake assist
systems
Brake assist systems can help the driver in crit-
ical driving or braking situations. The driver is
responsible for driving safely ››› .
When the brake assist systems are regulating
the brakes, the brake pedal may move or make
noises. Even so, continue to brake with the nec-
essary force and control the trajectory of the
vehicle if necessary.
Depending on the equipment, the ESC and TCS
settings can be changed in the vehicle.
●
The ESC, ABS and TCS can only operate cor-
rectly if the four wheels are fitted with the stipu-
lated tyres ››› .
●
If a fault occurs in the ABS, the ESC, TCS and
EDS also cease to function.
Electronic Stability Control (ESC)
The ESC helps to reduce the risk of skidding
and to improve stability in certain driving situa-
tions ››› .
Traction control (TCS)
The TCS reduces the driving force on skidding
wheels and adapts this force to suit the road
surface conditions. The TCS facilitates starting,
acceleration and hill climbing ››› .
Electronic brake pressure distribution (EBV)
Electronic brake force distribution (EBV) regu-
lates the braking force between the front and
rear axles. Excessive braking of the rear axle is
avoided and the vehicle remains stable during
the braking operation.
Anti-lock braking system (ABS),
The ABS can prevent the wheels from locking
up under braking until shortly before the vehicle
comes to a stop, and helps the driver maintain
control of the steering and the vehicle ››› .
Brake assist (BAS)
Brake assist (BAS) can help to reduce the brak-
ing distance. Brake Assist increases the pressure
exerted by the driver when the brake pedal is
depressed quickly in an emergency.
Electronic dierential lock (EDS and XDS)
The EDS automatically brakes skidding wheels
and transmits the driving force to the other driv-
ing wheels.
XDS improves traction by applying the brakes
to improve cornering acceleration.
Multi-collision brake
The multi-collision brake automatically triggers
braking if the airbag control unit detects a colli-
sion in the event of an accident.
Automatic braking requirements:
●
The driver is not pressing the accelerator
pedal.
Trailer stabilisation
1)
Note that the vehicle-trailer assembly generally
tends to snake. When the snaking of the trailer
is felt by the vehicle and detected by the ESC,
it will automatically brake the towing vehicle
within the limits of the system and stabiliser the
vehicle-trailer set ›››page312.
Electromechanical brake servo (eBKV)
With the ignition switched on, the electrome-
chanical brake servo (eBKV) supplements the
force exerted by the foot by increasing the
pressure that the driver exerts on the brake
pedal ›››
. When a driver assistance system
apples the brakes, e.g. ACC when regulating
the speed, or during emergency braking, the
brake pedal may move automatically.
