Automatic air recirculation t
The automatic air recirculation
system has an air quality sensor
which switches on automatically if
harmful ambient gases are detected.
Operated with the t button.
Activation is indicated by the LED in
the button.
The automatic air recirculation
system is only operational if the
engine is running.
Demisting and defrosting
■ Press button V. Activation is
indicated by the LED in the button.
■ Set fan to the desired speed.
Air recirculation mode 4 is
automatically switched off. Cooling
A/C switches on.
■ Switch on heated rear window RÜ .

To switch off window demisting and
defrosting, press button V again,
press AUTO button, adjust fan speed
or air distribution switch.Air vents
Adjustable air vents
At least one air vent must be open
while the cooling A/C is on.
To open and close the vents, turn the
horizontal adjuster wheel to the left or right.
Open air vents when air distribution switch is set to M or L.
The air supply is increased by
switching on the fan.
Control the air temperature at the side
air vents by adjusting the temperature
control switch.
Direct the flow of air by tilting and
swivelling the slats.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.

120Climate controlFixed air ventsAdditional air vents are located
beneath the windscreen, door
windows and in the front and rear foot
wells.
The area underneath the front seats
must be kept clear, to allow air flow to the rear passenger foot well.Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filterCabin air filtration
A particle filter cleans the cabin air
from dust, soot, pollen and spores.
Active carbon filter
In addition to the particle filter the
active carbon filter reduces odours.
Air conditioning regular
operation In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
week, irrespective of the weather and time of year. Operation with cooling is
not possible when outside
temperature is too low.
Service For optimal cooling performance, it isrecommended 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 andevaporator drainage
■ Performance check

Driving and operating125
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating, power steering and brake
performance will be maintained.
Air conditioning system may or may
not inhibit the stop-start system
according to the cooling performance.
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.
■ 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 vehicle battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high or low
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an engine stop
■ 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.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 116.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 122.
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
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.
Page 128 of 217

126Driving and operating
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates.
Control indicator - 3 89.
Restart of the engine by the
stop-start system
The selector lever must 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 charging level of the vehicle battery is below a defined level
■ the brake vacuum is not sufficient
■ the vehicle is driven at least at walking speed
■ the defrosting function is activated■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during 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 the electrical parking brake.
Pull switch m.
For maximum force, e.g. parking
with a trailer or on inclines, pull
switch m twice.
■ Switch off the engine and turn the ignition key to position LOCK, push
key into ignition switch and remove.
Turn the steering wheel until the
steering wheel lock is felt to
engage.For vehicles with automatic
transmission, depress foot brake
and shift into P before pushing key
into ignition switch and removing.
■ If the vehicle is on a level surface or
uphill slope, engage first gear ormove the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear or move the
selector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle with button p on
the radio remote control 3 20 and
activate the anti-theft alarm system 3 24.
