indicator ECO illuminates in the
instrument cluster when activated.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly. ECO flashes in the instrument
cluster.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal. ECO stops
flashing and illuminates continuously.

indicator ECO extinguishes in the
instrument cluster.
Driving and operating113Control of the vehicleNever coast with engine not
running
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.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
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.

If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
■ The stop-start system is manually deactivated.
■ the bonnet is opened.■ the vehicle battery is discharged.
■ the engine temperature is too low.
■ the brake vacuum is not sufficient.
■ the vehicle starts to move.
■ the defrosting function is activated 3 103.
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.
Fault If a fault occurs in the stop-start
system, the LED in button Î
illuminates, and a corresponding
message appears in the Driver
Information Centre 3 90. Seek the
assistance of a workshop.
Vehicle messages 3 91.
Warning chimes 3 91.Parking9 Warning
■ Do not park the vehicle on an
easily ignitable surface. The
high temperature of the exhaust system could ignite the surface.
■ 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 25 and activate the
anti-theft locking system 3 34 and
anti-theft alarm system 3 35.
122Driving 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 87.
Vehicle messages 3 91.
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 87.
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 86 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 87
and C 3 86 illuminate, there is a fault
in the braking system. A
corresponding message also
appears in the Driver Information
Centre 3 90. Have the cause of the
fault remedied by a workshop.
Vehicle messages 3 91.
Driving and operating123Parking brake9Warning
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 87.
Parking 3 119.
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 3 117.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the foot
brake to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system
