Control of the vehicle
Never 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 3 110.
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.
108Driving and operatingCaution
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.
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.

Do not operate the accelerator pedal. Diesel engine: turn the key to position1 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 2 and release.
Before restarting or to switch off the engine, turn the key back to position
0.
Autostop
During an Autostop, the engine is
restarted automatically by depressing
the clutch pedal.
Vehicles with manual transmission
automated (MTA): Shift to a forward
gear, release brake pedal or move
lever to +, – or R to enable an
automatic restart.
Stop-start system 3 110.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Vehicle shutdown
Fuel cut-off system In the event of a collision of a certain
severity, the fuel system is cut-off and
the engine is switched off
automatically, for safety reasons.
Control indicator 9 illuminates if the
fuel cut-off switch is triggered and, depending on version, a
corresponding warning message may
also appear in the Driver Information
Centre (DIC) 3 85.
Generic warning control indicator 9
3 76.
Notice
In addition, the vehicle is
automatically unlocked and the
hazard warning flashers and interior lights are illuminated.
Turn the ignition key to position 0 to
prevent battery discharge and seek
the assistance of a workshop
immediately. Have the vehicle
checked for fuel leaks in the engine
compartment, beneath the vehicle
and near the fuel tank.
112Driving and operatingRestarting the engine
Manual transmission
The selector lever must be in neutral
to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the
brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
● the driver's seat belt is unfastened and the driver's door
is opened
● three minutes have elapsed since the engine was switched offIn this event, control indicator ^
flashes in the DIC in conjunction with
a warning chime. Depending on
version, a corresponding message
may also appear in the DIC 3 85.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 84.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A warning
message may also be displayed in
the DIC 3 85.
Generic warning 9 3 76.
Seek the assistance of a workshop.
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 brake
pedal at the same time to
reduce operating force.
● Switch off the engine. Turn the ignition key to position 0 and
remove it. Turn the steering
wheel until the steering wheel
lock is felt to engage.
● If the vehicle is on a level surface or uphill slope, engage
first gear before switching off
the ignition. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before switching off the ignition. Turn the front wheels towardsthe kerb.
Lock the vehicle 3 21 and activate the
anti-theft locking system 3 26 .
Driving and operating119Brakes
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 79.
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 79.
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
Driving and operating127A slight loss of power and torque can
be expected in petrol operation. You
must therefore adapt your driving
style (e.g. during overtaking
manoeuvres) and vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Refuelling
Fuel filler flap is located at left rear side of vehicle.9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Release the fuel filler flap by pulling
the flap by hand.
Insert key into fuel filler cap and turn
anticlockwise to unlock.
To remove fuel filler cap, rotate
anticlockwise.
Caution
To avoid damage, do not attempt
to operate the sliding side door
when the fuel filler flap is open.
Notice
Depending on model, the sliding
side door may be fitted with a safety system that prevents the door from
being opened fully when the fuel
filler flap is open.
Sliding side door 3 23.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
128Driving and operatingTo refuel, fully insert the pump nozzle
and switch it on.
After the automatic cut-off, the fuel
tank can be topped up with a
maximum of two doses of fuel.Caution
Wipe off any overflowing fuel
immediately.
To close, replace fuel filler cap and
turn clockwise.
Insert key into fuel filler cap and turn
clockwise to lock, then remove key.
Close the fuel filler flap.
Natural gas refuelling
Open the fuel filler flap.
9 Warning
Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed, i.e. the filler neck must be
vented.
The capacity of the natural gas tank depends on outside temperature,
filling pressure and type of refuelling
system.
Close the fuel filler flap after
refuelling.
