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
Page 107 of 183

Driving and operating105immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.
Fuel system messages 3 86.
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.
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.
Deactivation
Deactivate the stop-start system
manually by pressing the ^ button in
the centre console. LED in the button
illuminates to confirm deactivation.
Depending on version, a
corresponding message may also appear in the Driver Information
Centre 3 80.
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 80.

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.

Vehicle care127
■ Open the bonnet, close all doorsand lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are
not functional, e.g. anti-theft locking
system.
Putting back into operation When the vehicle is to be put back into
operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir. ■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plates if necessary.End-of-life vehicle
recovery Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our
website. Only entrust this work to an
authorised recycling centre.

natural gas vehicles.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.

Vehicle care131BrakesA squealing noise, or illumination ofbrake pad wear control indicator F
indicates that the brake lining is at its
minimum thickness.
Continued driving is possible but
have the brake linings replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake pad wear indicator F 3 75.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use high-performance brake
fluid approved for the vehicle.
Brake and clutch fluid 3 162.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.

when replacing the battery. We
recommend that you have the battery
replaced by a workshop.
