106Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
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
Driving and operating109Starting the engine
Manual transmission: operate clutch
and brake.

automatically shifts to N (neutral)
Do not operate the accelerator pedal. Diesel engine: turn the key to position1 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 2 and release.
Before restarting or to switch off the engine, turn the key back to position
0.
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 3 110.
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.
Control 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 Information
Centre (DIC) 3 85.
Generic warning control indicator 9

Notice
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 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.
Vehicle care133Vehicle storageStorage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, well ventilated place. Engage first or
reverse gear to prevent the
vehicle from rolling.
● Do not apply the parking brake.● Open the bonnet, close all doors and 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 must be recycled by a service centre authorised for
natural gas vehicles.
Vehicle care153Relearn function
After changing wheels, TPMS needs
to recalculate. The relearn process
takes up to 20 minutes of driving with
a minimum speed of 15 mph.
If problems occur during the relearn
process, control indicator w flashes
for several seconds then illuminates
continuously and (depending on
version) a warning message is
displayed in the DIC.
Driver Information Centre (DIC) 3 85.
General information The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 154, Tyre chains
3 154.
External high-power radio equipment
could disrupt the TPMS.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.

Recommended fluids andlubricants
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
3 171.
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
3 171.
Service and maintenance169Additional 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 3 171.
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 low
temperatures the factory filled coolantprovides 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 fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
