■ Always apply parking brake without pressing release button.Apply as firmly as possible on a
downhill slope or uphill slope.
Depress foot brake at the same
time to reduce operating force.
■ Switch off the engine.
■ If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards
the kerb.
Lock the vehicle 3 23 and activate the
anti-theft locking system 3 32 and

120Driving and operatingBrakes
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 you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your 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.
If control indicator R illuminates in
the instrument cluster while driving and a corresponding message
appears in the Driver Information
Centre, there is a fault in the braking
system. Seek the assistance of a
workshop immediately.Control indicator R 3 85.
Vehicle messages 3 89.
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.
Control indicator u 3 85.
Fault
If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while driving, there is a fault in the ABS.
Control indicator F 3 84 may alsoilluminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre. The brake system remains
operational but without ABS
regulation.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.
If control indicators u, F , R 3 85
and C 3 84 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the Driver Information
Centre 3 88. Have the cause of the
fault remedied by a workshop.

122Driving and operatingRide control systems
Traction Control system
The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive 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.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster. A corresponding
message also appears in the Driver
Information Centre 3 88.

Electronic stability
program
The Electronic Stability Program
(ESP® Plus
) improves driving stability
when necessary, regardless of thetype of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.

In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is selectively braked until the snaking
ceases. While the system is working, keep steering wheel as still as
possible.
