To preventt he windows from foggingu p:
Ronly switchoff climatec ontrolbriefly
Ronly switc honair-recirculation mode briefly

Climate contro lregulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate contro lisonly operational when the
engin eisrunning. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for abrief period during
warm weather. In order to cool the vehicle more
rapidly, switc hclimat econtro ltoair-recircula-
tion mode briefly. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
The integrated filter can filter out most particles
of dust and completely filter sout pollen. In vehi-
cles with automatic climatec ontrol, gaseous
pollutant sand odors will also be reduced. A
clogged filter reduces the airflow int othe vehi-
cle interior. For this reason,y ou should always
observet he interval for replacin gthe filter,
which is specified in the Maintenance Booklet.
As the interval between changes depends on
environmental conditions, e.g. heavy air pollu- tion
,the interval may be shorter than stated in
the Maintenance Booklet.

Climate control

RIf you wish to use the driver's side settings on
the front-passenger side and, for vehicles
with rear-compartment air conditioning, for
the rear compartment as well,use the "Syn-
chronization" function. The indicator lamp in
the 0 button comes on when the function
is switched on.
RAfter long journeys, you can use the residual
heat of the engine to heat the stationary vehi-
cle. The residual heat function can only be
switched on or off whilet he ignition is
switched off. The indicator lamp in the Ì
button comes on when the function is
switched on.
Approximatel y60minutes after parking the
vehicle,a utomatic climate control can switch on
automatically ,depending on the outsid etem-
perature. The vehicle is then ventilated for about
30 minutes at low fan setting and the automatic
climate control system is dried out.
During automatic engine switch-off, the climate control system only operates at areduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 122).
Information on rear-compartment air
conditioning
Vehicles with TEMPMATIC air-conditioning
system
Switch the rear-compartment air-conditioning
system on and off using the TEMPMATIC air-
conditioning system control panel. When you
switch on the rear-compartment heating, the
settings for temperature ,airflow and air distri-
bution are automatically adopted on the control
panel for the rear-compartment heating.
The indicator lamp in the /button comes on
when the rear-compartment air-conditioning is
switched on (
Ypage 108).
Vehicles with automatic climate control
To operate the rear-compartment air condition-
ing, use the control panel of the automatic cli-
mate control system. When you switch on the
rear-compartment air conditioning, you can set
the temperature and airflow separately on the
control panel .The airflow setting is automati-
cally adopted for the rear-compartment air con-
ditioning. When automatic climate control is in
à automatic mode, the air distribution of the
rear-compartment air conditioning is also auto-
matically adjusted. When you set the temperature and airflow of the
rear-compartment air conditioning, the indica-
tor lamp of the
/button (
Ypage 109)
flashes. When the rear-compartment air condi-
tioning is switched on, the indicator lamp on
the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡(22 †) and switch on Ãauto-
matic mode. Only change the temperature in
small increments.
