Adjustable air vents At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to lack of air movement.
Centre air vents
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, swivel the slat
towards the outside of the vehicle.

Climate control223Maintenance
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.
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 to annually check the
climate control system, starting
3 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 checkNote
Refrigerant R-134a may contain
fluorinated greenhouse gases with a global warming potential of 1430.
Front air conditioning system is filled
with 0.58 kg and has a CO 2
equivalent of 0.83 tonnes, the front
and rear air conditioning system in
Combi variants is filled with 1.1 kg
and has a CO 2 equivalent of
1.57 tonnes and the front and rear air
conditioning system in Bus variants
is filled with 1.7 kg and has a CO 2
equivalent of 2.43 tonnes.
Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.

Otherwise an Autostop will be
inhibited.An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 208.
Immediately after motorway driving
an Autostop may be inhibited.

Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driverManual transmission
With the selector lever in neutral,
depress the clutch pedal to restart the
engine.
Note
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.If the engine does not restart first
time, depress clutch pedal fully again.Manual transmission automated
With the selector lever in position D,
M or N and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing the accelerator pedal may also restart
the engine.
The control indicator Ï will extinguish
in the instrument cluster when the
engine is restarted. If certain
conditions are not fulfilled, a restart will not take place. Start using the
ignition key.
