the engine is switched off

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 3 103.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
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
battery.
Diesel particle filter 3 106.
112Driving 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 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 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 74.
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.
After starting off the system performs a self-test which may be audible.
Control indicator u 3 75.
Fault9 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 nolonger be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake Manual parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
Driving and operating113
To release the parking brake, pull thelever 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.
A warning chime will sound if a certain speed is exceeded with the parking
brake applied.
Notice
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 79.
Control indicator R 3 74.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.Hill start assist
The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
If control indicator Z illuminates
while driving, there is a fault in the Hill
start assist 3 75 . Seek the assistance
of a workshop to have the fault
remedied.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 103.Ride control systems
Traction Control system
The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Program (ESP).
ASR 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.
ASR is operational as soon as the
control indicator x extinguishes.
When ASR is active, control indicator x flashes.
116Driving and operating
Alternatively accelerate to the desiredspeed and store by pushing lever
upwards ( +).
Reduce speed
With cruise control active, push lever
downwards ( -) or briefly push lever
downwards ( -) repeatedly; speed
decreases continuously or in small
increments.
Deactivation
Automatic deactivation:
■ vehicle speed below approx. 20 mph,
■ the brake pedal is depressed,
■ the clutch pedal is depressed,
■ the traction control system/Anti-Slip
Regulator (ASR) or Electronic
Stability Program (ESP) is
operating.
Resume stored speed Press button = at a speed above
20 mph. The stored speed will be
obtained.Switching off
Turn end of lever to the OFF position;
control indicator m extinguishes. The
stored speed is deleted. Switching off the ignition also deletes the stored
speed.Object detection
systems
Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper.
