If you wish to use the driver's side settings
on the co-driver's side and, for vehicles with
rear-compartment air conditioning, for the
rear compartment as well, use the "Synchro-
nization" function. The indicator lamp in the
0 button comes on when the function is
switched on.
R After long journeys, you can use the residual
heat of the engine to heat the stationary
vehicle. The residual heat utilization can
only be switched on or off while the ignition
is switched off. The indicator lamp in the
Ì button comes on when the function is
switched on.
Approximately 60 minutes after parking the
vehicle, 3-zone automatic climate control can
switch on automatically, depending on the out-
side temperature. The vehicle is then ventila-
ted for about 30 minutes at low fan setting
and 3-zone automatic climate control is dried
out. Optimum use of the rear compart-
ment air conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning
system control panel. When you switch on the
rear-compartment air conditioning, your set-
tings for temperature, airflow and air distribu-
tion are automatically adopted on the control
panel for the rear-compartment air condition-
ing.
The indicator lamp in the / button comes
on when the rear-compartment air-condition-
ing is switched on
(Y page 115).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condi-
tioning, use the control panel of the dual-zone
automatic climate control system. When you
switch on the rear-compartment air condition-
ing, you can set the temperature and airflow
separately on the control panel. The airflow
setting is automatically adopted for the rear-
compartment air conditioning. When dual-zone
automatic climate control is in à automatic
mode, the air distribution of the rear-compart-
ment air conditioning is also automatically
adjusted.
When you set the temperature and airflow of
the rear-compartment air conditioning, the indicator lamp of the / button
(Y page

116) flashes. When the rear-compart-
ment air conditioning is switched on, the indi-
cator lamp on the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on à auto-
matic mode. Only change the temperature in
small increments. Operating the climate control sys-

midification function on/off
Important safety notes The cooling with air dehumidification function
of the air conditioning or automatic climate
control is only available when the engine is
running. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may appear on the underside of
the vehicle when in cooling mode. This is nor-
mal and not a sign that there is a malfunction.
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle
will not be cooled (in warm weather) or dehu-
midified. Therefore, only switch off the "Cool-
ing with air dehumidification" function briefly.
Otherwise, the windows will fog up more
quickly.
Switching on and off For dual-zone automatic climate control, the
function for automatic climate control settings
can only be activated or deactivated on the
first menu level. If you do not set a new value
for the rear-compartment climate control in
the second menu level within approx. ten sec-
onds, the control panel display goes back to
the first menu level.
X Press the ¿ button.

Regulating climate control automati-
cally
General notes When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification func-
tion is also activated. If desired, the cooling
with air dehumidification function can be deac-
tivated (
Y page 118).
Dual-zone automatic climate control Automatic mode for automatic climate control
settings can only be activated or deactivated
on the first menu level. If you do not set a new
value for the rear-compartment climate control
in the second menu level within approx. ten
seconds, the control panel display goes back
to the first menu level.
