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 isstationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking the
assistance of a workshop 3 128.

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.
Depending on version, a
corresponding warning message may
also appear in the Driver Information Centre 3 80.
To reset the fuel cut-off system and
enable the vehicle to be driven, refer
to " Vehicle shutdown " 3 104.
Driving and operating103Starting 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.

104Driving and operating
Before restarting or to switch off the
engine, turn the key back to position
STOP .
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 3 105.
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.
Depending on version, a
corresponding warning message may
also appear in the Driver Information Centre 3 80.
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 3 103
2. Fully actuate the right turn signal light 3 91
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
106Driving and operating
During an Autostop, the heating,
power steering and brake
performance will be maintained.Caution
The steering assist can be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
Otherwise an Autostop will be
inhibited.
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed and the driver's seat belt is fastened
■ the battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is not too low
■ 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.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 103.Battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Restarting 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.
Driving and operating107
■ the driver's seat belt is unfastenedand the driver's door is opened
■ three minutes have elapsed since the engine was switched off
In this event, control indicator ^
flashes in the Driver Information
Centre in conjunction with a warning
chime. Depending on version, a
corresponding message may also
appear in the Driver Information
Centre 3 80.
Fault If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 79.
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 Driver Information Centre 3 80.
Generic warning 9 3 73.
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 foot brake at the same
time to reduce operating force.
■ Switch off the engine. Turn the ignition key to position STOP
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 towards
the kerb.
Lock the vehicle 3 21 and activate the
anti-theft locking system 3 26 .
Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Driving and operating121
Fuel selector
Pressing button Y in the centre
console switches between petrol and
natural gas operation. The LED 1
status shows the current operating
mode.
1 off=natural gas
operation.1 illuminates=petrol operation.
As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 80 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.
