Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 108.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Power steering Never leave the steering wheel on full
lock when the vehicle is stationary as this may damage the power steering
pump.Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be inhibited to allow for charging the
vehicle battery.

118Driving 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.
Control indicator R 3 79.
If the brake pads wear to a
predetermined point, the braking
system will require inspection. Seek
the assistance of a workshop.
Control indicator F 3 80.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 80.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in the ABS. 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, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.
