New vehicle running-in 3 133.Vehicle battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
Note
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.
The engine restart may be interrupted
if the clutch pedal is released too
quickly while a gear is engaged.
If the engine does not restart first
time, depress clutch pedal fully again.
Alternatively, press button Î to
restart the engine while in an
Autostop.
Control indicator Ï 3 102
extinguishes in the instrument cluster when the engine is restarted.Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● the vehicle battery is discharged
● the outside temperature is too low or too high (e.g. below 0 °C
or above 35 °C)
● the defrosting function is activated 3 120
● the brake vacuum is not sufficient
● the brake pedal is operated repeatedly
● the vehicle starts to move
An automatic engine restart may not
be possible if a door or the bonnet is
open.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during engine restart may be
noticeable.
148Driving and operatingCaution
It is inadvisable to drive with hand
resting on the selector lever.
Upshift 3 100.
Stop-start system 3 137.
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 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 3 103, there is a fault in the
braking system. Seek the assistance
of a workshop immediately.Control indicator R 3 99.
Vehicle messages 3 104.
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 3 100.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates while
Driving and operating149driving, there is a fault in the ABS.
Control indicator j 3 99 may also
illuminate 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, j , R 3 99
and C 3 99 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the Driver Information
Centre 3 103. Have the cause of the
fault remedied by a workshop.
Vehicle messages 3 104.
Parking brake9 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
brake pedal at the same time.
Control indicator R 3 99.
Parking 3 140.
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.
Brake assist is not available during an
Autostop.
Stop-start system 3 137.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on

Vehicle care201Towing another vehicle
The fixed towing eye is located underthe rear bumper, on the left vehicle
side.
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
The rear towing eye must only be
used for towing and not recovering a
vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Trailer hitch 3 163.
Appearance care
Exterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has adegreasing effect and impairs lockfunction. After using a de-icing agent,
have the locks regreased by a
workshop.
Washing
The paintwork of your vehicle is
exposed to environmental influences, therefore wash your vehicle regularly.
When using automatic vehicle
washes, we recommend one with
textile brushes and a programme
without wax additives. Restrictions for
filmed or matt painted body parts or
decor tapes, see "Polishing and
waxing".
Never use a steam-jet or high-
pressure jet cleaner for the engine
compartment.
