Important safety notes
G
WARNING
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. You might otherwise drive
without the steering wheel adjustment mech-
anism being locked in position. As a result,
you could be distracted from road and traffic
conditions by an unintentional movement of
the steering wheel and thereby cause an acci-
dent.
However, the steerability of the vehicle is not
affected. Adjusting the steering wheel man-

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mis tup. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
THERMATIC/THERMOTRONIC automatic cli-
mate control controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running 17
.O ptimum operation is
only achieved if you drive with the side win-
dows and sliding sunroof/panorama sliding
sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out pollen.
Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry
the air-conditioning system.
17 THERMOTRONIC automatic climate control: the residual heat function can only be activated/deactivated
when the ignition is switched off. 136

R Set the temperature to 22 †.
R Only use the demisting function briefly,
until the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp above the ábutton goes
