Troubleshooting
Defect in the brake system
The warning lamp lights up red. A message may
also be displayed.
Stop driving!
●
Inform a specialist workshop and request a
brake system inspection.
Brake pad wear indicator
The control lamp switches on yellow.
The front brake pads are worn.
●
Contact a specialised workshop immediately.
●
Get all the brake pads inspected and replace
if necessary.
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
necessary force and control the trajectory of
the vehicle if necessary.
170
Depending on the equipment, the ESC and
TCS settings may be changed in the vehicle.
●
The ESC, ABS and TCS can only operate cor-
rectly if the four wheels are fitted with the
stipulated 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 vehi-
cle comes to a stop, and helps the driver main-
tain 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 pres-
sure exerted by the driver when the brake
pedal is depressed quickly in an emergency.
Electronic differential lock (EDS and XDS)
The EDS automatically brakes skidding wheels
and transmits the driving force to the other
driving wheels.
The XDS improves traction by applying the
brakes to keep the vehicle in its lane.
Multi-collision brake
The multi-collision brake automatically triggers
braking if the airbag control unit detects a col-
lision in the event of an accident.
Automatic braking requirements:
●
The driver is not pressing the accelerator
pedal.
Tractor-trailer sway mitigation
If the vehicle is pulling a trailer, it will con-
trol the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
