Heated rear window Ü 3 35.
Temperature
red:warmblue:coldHeating will not be fully effective until
the engine has reached normal
operating temperature.
Air distributions:to windscreen and front door
windowsM:to head area via adjustable air
ventsK:to foot well
All combinations are possible.
Fan speed
Adjust the air flow by switching the fan to the desired speed.
Climate control161Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel towards the smaller W symbol.
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.
Driving and operating169key. Turn the front wheels
towards the kerb.
● Close the windows and the sunroof.
● Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 227.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
