Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
When braking in an emergency, the
hazard warning flashers are switched
on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
After starting off, the system performs a self-test which may be audible.
Control indicator i 3 68.
Fault
9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.

Braking when vehicle is moving
When the vehicle is moving and the
switch j is kept pulled, the electric
parking brake system will decelerate the vehicle. As soon as the switch
j is released, braking will be
stopped.
The antilock brake system and the
Electronic Stability Control stabilise
the vehicle while the switch j is kept
pulled. If an error of the electric
parking brake occurs, a warning
message is displayed in the driver
information centre. If the antilock
brake system and the Electronic
Stability Control fail, one or both
indicators i and J illuminate in the
instrument cluster. In this case,
stability can only be provided by
repeatedly pulling and pushing the
switch j until the vehicle is
immobilised.Automatic operation

Electronic Stability Control and Traction Control system
Electronic stability control improves
driving stability when necessary,
regardless of the type of road surface
or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the
wheels are braked individually.
Electronic stability control operates in combination with the traction control
system. It prevents the driven wheels
from spinning.
The traction control system is a
component of the electronic stability
control.
The traction control system improves
driving stability when necessary, regardless of the type of road surface
or tyre grip, by preventing the driven
wheels from spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
118Driving and operatingindividually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
Electronic stability control and the
traction control system are
operational after each engine start as
soon as the control indicator J
extinguishes.
