Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 84.
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 u 3 85.
Page 140 of 245

138Driving and operatingFault9Warning
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.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator j illuminate constantly
when electric parking brake is
applied.
9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Control indicator R 3 84.
Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.

Driving and operating139Ride control systems
Electronic Stability Control and Traction Control system
Electronic stability control (ESC)
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.
ESC operates in combination with the traction control system. It prevents
the driven wheels from spinning.
The traction control system is a
component of the ESC and prevents
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
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ESC and traction control system are
operational after each engine start as
soon as the control indicator b
extinguishes.
When ESC and traction control
system operate, b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Additionally at least the third gear
must be engaged on manual
transmission.
Additionally position D or the second
or a higher gear in position M must be
selected on automatic transmission.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal firmly.
