When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle is stationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking the
assistance of a workshop 3 127.

Fuel system messages
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. A
corresponding warning message may also appear in the Driver Information
Centre 3 79.To reset the fuel cut-off system and
enable the vehicle to be driven, refer
to " Vehicle shutdown " 3 103.

Before restarting or to switch off the
engine, turn the key back to position

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 3 103.
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.
Driving and operating103
Turbo engine warm-upUpon 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. A
corresponding warning message may
also appear in the Driver Information
Centre 3 79.
Notice
In addition, the vehicle is
automatically unlocked and the
interior lights are illuminated.
Turn the ignition key to position
STOP to prevent battery discharge
and seek the assistance of a
workshop immediately. Have thevehicle checked for fuel leaks in the
engine compartment, beneath the
vehicle and near the fuel tank.
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position MAR 3 102
2. Fully actuate the right turn signal light 3 90
3. Deactivate the right turn signal light
4. Fully actuate the left turn signal light
5. Deactivate the left turn signal light
6. Repeat steps 2, 3, 4 and 5.
7. Turn the ignition key to position STOP .9Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have thecause of this remedied
immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.
Fuel system messages 3 85.
Overrun cut-off
The fuel supply is automatically cut-
off during overrun, i.e. when the
vehicle is driven with a gear engaged but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce exhaust emissions.
When conditions allow, it switches off the engine as soon as the vehicle is
at a low speed or at a standstill, e.g.
at a traffic light or in a traffic jam. It
starts the engine automatically as
soon as the clutch is depressed.
A battery sensor ensures that an
Autostop is only performed if the
battery is sufficiently charged for a
restart.
Driving and operating105
■ the ambient temperature is not toolow
■ the climate control system allows an Autostop
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
■ the brake vacuum is sufficient
■ the windscreen wipers are not operating at fast speed
■ reverse gear is not selected
■ heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an Autostop.
For manual transmission automated
vehicles, an Autostop may be
inhibited until a speed of approx.
6 mph is reached.
New vehicle running-in 3 101.
Battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.Restart 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.
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 off
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.Parking
■ 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. Apply manual parking brake without
pressing release button. Apply as
firmly as possible on downhill or uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ 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.
120Driving and operating
indicator Y illuminates in the Driver
Information Centre 3 79 until the
ignition is switched off.
A 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.
