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.
104Driving and operating
ActivationThe stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
Deactivation
Deactivate the stop-start system
manually by pressing the ^ button in
the centre console. LED in the button
illuminates to confirm deactivation.
Autostop
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
■ Depress the clutch pedal
■ set the lever to neutral
■ release the clutch pedal
The engine will be switched off while the ignition stays on.
An Autostop is indicated when control indicator ^ flashes in the Driver
Information Centre 3 79.
During an Autostop, the heating 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
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.
110Driving and operating
When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake has not
been depressed.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect,
select a lower gear in good time when driving downhill.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.
Parking
Apply the parking brake. The most recently engaged gear (see
transmission display) remains
engaged. With N, no gear is engaged.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a warning chime will sound upon
opening the driver's door.Manual mode
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown.

Electronic stability
program
Electronic Stability Program (ESP)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. Thisconsiderably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP is operational as soon as control
indicator x extinguishes.
When ESP comes into action, control indicator x flashes.
The ESP system is automatically
activated when the vehicle is started
and cannot be deactivated9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.

Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper.
Control indicator r 3 75.
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.
