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.
