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

lubricants and parts
Recommended fluids and
lubricants Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
ageing control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for petrol and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Recommendations for petrol engines
are also valid for Compressed Natural
Gas (CNG) fuelled engines.
Select the appropriate engine oil
based on its quality and viscosity
3 165.
Topping up engine oil
Engine oils of different manufacturers and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and viscosity
3 165.

Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity
The SAE viscosity grade gives
information on the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature
viscosity.
Select the appropriate viscosity grade 3 165.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze Use only antifreeze approved for the
vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very lowtemperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
