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.
Control indicator 9 3 81 illuminates if
the fuel cut-off switch is triggered and,
depending on version, a
corresponding warning message may also appear in the Driver InformationCentre 3 90.

allow air intake. Remove any leaves,
dirt or snow.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended that the climate control system be checked annually, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check

automatic restart.
Stop-start system 3 116.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 vehicle
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.
116Driving and operatingControl 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 InformationCentre 3 90.
Generic warning control indicator 9
3 81.
Note
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 vehicle 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.
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 1
3 114.
2. Fully actuate the right turn signal light 3 101.
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 0.9 Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have the
cause 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 96.
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.
Depending on driving conditions, the
overrun cut-off may be deactivated.
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 vehicle battery sensor ensures that an Autostop is only performed if thevehicle battery is sufficiently charged
for a restart.
Activation
The 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.
Driving and operating117Deactivation
Deactivate the stop-start system
manually by pressing ^ in the centre
console. LED in the button illuminates
to confirm deactivation.
Depending on version, a
corresponding message, e.g.
Start&Stop disconnected , may also
be displayed in the Driver Information
Centre 3 90.
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 90.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The power steering assist may 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 vehicle 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
118Driving and operating● the self-cleaning function of thediesel 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.
10 km/h is reached.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 114.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle 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 conditionsoccurs 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 Driver Information
Centre in conjunction with a warning
chime. Depending on version, a
corresponding message may also be
displayed in the Driver Information
Centre 3 90.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 89.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A
corresponding warning message,
e.g. Start&Stop unavailable , may also
be displayed in the Driver Information
Centre 3 90.
Generic warning 9 3 81.
Seek the assistance of a workshop.
