els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variation sare pos-
sible. Note that your vehicl emay not be
equippe dwith all of the function sdescri-
bed. This is also the case for system sand

WARNING
Observ ethe settings recommende donthe
followin gpages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
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. The system only works
optimally if 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 147).
i Ven tilate the vehicle for abriefp eriod
during war mweather ,e.g. using the con-
venienc eopening feature (Y page 90).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached mor equickly.
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 observ ethe interval for replacing the filter
,which is
specifie dinthe Servic eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Servic eBooklet. 136

nabout using THERMATIC
automatic climate control
The following contains notes and recommen-
dation sonoptimum use of THERMATIC auto-
matic climate control.
R Activat eclimate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 22 †.
R Only use the demisting func tion briefly until
the windscreen is clea ragain.
R Only use the air-recirculation mode briefly,
e.g. if ther eare unpleas anto utside odours
or when in atunnel. The windows could
otherwis emist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE func tion to adopt the tem-
peratur esettings on the driver' sside for
the front-passenger side as well. The indi-
cator lamp above the ábutton goes
out. 138

THERMOTRONIC automatic climate
control
The following contains instructions and rec-
omm endations to enabl eyou to get the most
ou tofy our THERMOTRONIC automatic cli-
mate con trol.
R Activate climate con trol using the Ãand
¿ buttons. The indicator lamps above
the à and¿ button slight up.
R In automatic mode, you can also use the
ñ button to set aclimate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIU Mlevel is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscreen is clear again.
R Only use the air-recir culation mode briefly,
e.g. if there are unpleasant outside odours
or when in atunnel. The windows could
otherwis emist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE func tion to adopt the tem-
peratur esettings on the driver' sside for
the front-passenger side and the rear com-
partmen taswell. The indicator lamp above
the á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicl einterior
whe nthe ignition is switched off .The resid-
ual heat func tion can only be activated or
deactivated with the ignition switched off. Operating th
