Instructions and recommendations for
optimum air conditioning:
R activate the air conditioning using
the à andÁ buttons. The indica-
tor lamps in the ÃandÁ buttons
come on.
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 out-
side odours or when in a tunnel. Other-
wise, the windows could mist up due to
a lack of fresh air.
R use the "residual heat" function if you
want to heat or ventilate the vehicle inte-
rior when the ignition is switched off. The
"residual heat" function can only be acti-
vated or deactivated with the ignition
switched off.
R use the "MONO" function if you want to
adopt the temperature, air distribution
and airflow settings from the driver's side
for all air-conditioning zones. The indica-
tor lamp in the ºbutton comes on. Switching the air conditioning on/off

fication on/off
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. G
Risk of accident
If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.
X To activate: press theÁbutton.
The indicator lamp in the Ábutton
comes on.
X To switch off: press theÁbutton.
The indicator lamp in the Ábutton goes

function has a delayed switch-off feature. Controlling the air conditioning auto-
matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated.

Risk of accident
Make sure that all windows are clear of ice
and snow before starting a journey. This may
otherwise obstruct your view of the traffic
conditions, thereby causing an accident.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.

from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the engine has been switched off. The heating
time depends on the temperature that has
been set.

Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore Air conditioning

G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged.
i When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. They are caused by
minor pressure fluctuations in the vehicle
interior. Change the position of the sliding
sunroof or open a side window slightly to
reduce or eliminate these noises.
