AIRSCARF
Activating/deactivating G
WARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot. The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.
The warm air flows out of the holes in the head restraints.
The three red indicator lamps in the button
indicate the heating level you have selected.
X Make sure that the key is in position 2in the
ignition lock.
X To switch on: press button:.
Three red indicator lamps in the button light up. The blower starts up after a preheating
phase of seven seconds.
X Press button :repeatedly until the
desired heating level is set.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
i The blower continues running for seven
seconds to cool down the heating ele-
ments.
i If the battery voltage is too low, AIRSCARF
may switch off. Problems with AIRSCARF AIRSCARF has switched off prematurely or
will not switch on. The vehicle's electrical sys-
tem voltage is too low because too many
electrical consumers are switched on.
X Switch off electrical consumers that you do
not need, such as the rear window heating
or interior lighting.
X Switch on AIRSCARF again. Steering wheel
Important safety notes
G
WARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar. G
WARNING
Children could become trapped by the steer-
ing wheel if they adjust it. There is a risk of
injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. 100

Adjusting the exterior mirrors G
WARNING
The exterior mirrors reduce the size of the
image. Objects visible in the mirrors are
closer than they appear. You could misjudge
the distance from road users driving behind
you when changing lanes, for instance. There is a risk of an accident.
You should therefore always look over your
shoulder to determine the actual distance
from road users driving behind you. G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users travelling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users travelling behind by glancing over your shoulder. X
Make sure that the key is in position 1or 2
in the ignition lock.
X Press button :for the left-hand exterior
mirror or button ;for the right-hand exte-
rior mirror.
The indicator lamp in the corresponding
button lights up in red.
The indicator lamp goes out again after
some time. You can adjust the selected
mirror using adjustment button =as long
as the indicator lamp is lit.
X Press adjustment button =up, down, to
the right or to the left.
The exterior mirror must be set to a position
that provides you with a good overview of
traffic conditions.
The convex exterior mirrors provide a larger
field of vision.
After the engine has been started, the exte-
rior mirrors are automatically heated if the
rear window heating is switched on and the
outside temperature is low. Heating takes a
maximum of 10 minutes.
i The exterior mirrors can also be heated
manually by switching on the rear window
heating. Mirrors

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 135).
i Ventilate the vehicle for a brief period
during warm weather. This will speed up the
cooling process, and the desired vehicle
interior temperature will be reached more
quickly. i
The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odours. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve the interval for replacing the filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. 126

R Set the temperature to 22 †.
R Recommendation for air distribution in
winter: adjust the Oand¯ settings.
Recommendation for air distribution in summer: adjust the Psetting. R
Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.

with air dehumidification function
General notes If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only switch off cooling with air dehumidifica-
tion for a short period.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
