2. Charge the battery by driving continuously for a while or by
using a charging device.The warning message or warning
code will disappear after the engine has been started twice consecutively
without a voltage drop.
If the battery cannot be recharged,
have the cause of the fault remedied
by a workshop.
120Climate control
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel to the left.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
Maintenance
Air 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 the
outside temperature is too low.
Service
For optimal cooling performance, it is
recommended to annually check the
climate control system, 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
124Driving and operating
Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
Deactivation is indicated when the
LED in the button extinguishes.
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 in neutral
■ release the clutch pedal
The engine will be switched off while
the ignition stays on.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the battery is sufficiently chargedand 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 brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Ambient temperature near to the
freezing point can inhibit an Autostop.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details.
Driving and operating125
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 122.
Battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched into a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the
driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a message in the Driver Information Centre.
Control indicator - 3 85.
Restart of the engine by the
stop-start system
The selector lever has to be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during engine restart might 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 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.

Wheels and tyres
Tyre condition, wheel conditionDrive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a workshop in the event of damage or
unusual wear.
Tyres Tyres of size 195/70 R16 and
215/60 R17 are only to be used as
winter tyres.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Tyre designations

Q=up to 160 km/hS=up to 180 km/hT=up to 190 km/hH=up to 210 km/hV=up to 240 km/hW=up to 270 km/h
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Unscrew the valve cap.
178Vehicle careWheel coversWheel covers and tyres that are
factory-approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory-approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with alloy wheels: When
mounting steel wheels with alloy
wheel nuts, e.g. when changing to
winter tyres, the wheel covers cannot
be attached to the steel wheels.
Tyre chains
Use tyre chains only on front wheels.
9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on tyres of
size 195/70 R16.
Always use fine mesh chains suitable
for sport utility vehicles that add no
more than 12 mm to the tyre tread and the inboard sides (including chain
lock).
On tyres of size 215/55 R18, special
snow chains are only permitted when
they are designed with a rotating
chain belt on the tyre tread, no chain
links on the wheel inboard sides and
the chains add no more than 12 mm
to the tyre tread. For further
information of right snow chain usage
for this tyre size, contact a specialized vehicle parts dealer or snow chain
manufacturer.
Tyre chains are not permitted on tyres of size 205/70 R16, 215/65 R16 and
