panel located in the rear centre console. These controls are used to make the
appropriate settings for the rear seats.

automatically switched off. To defrost the windscreen more
quickly, the air is dehumidified at temperatures over approxi-
mately +1.5 °C (+35 °F) and the fan runs at maximum output.

WARNING
Never turn off the air fan for a long time or the air in the passenger compart-
ment will not be refreshed.
xStuffy or used air will increase fatigue and reduce driver and passenger
concentration possibly resulting in a serious accident.
Note
Not all Climatronic buttons are operational in REAR mode.
Note
The button is locked in defrost mode.
Climate control user instructions
The cooling system only works when the engine is running and fan is
switched on.
The climate control system operates most effectively with the windows and
the sliding panoramic roof closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows briefly.
Keep the air vents in front of the windscreen free of snow, ice and leaves to
ensure heating and cooling are not impaired and to prevent the windows
from misting over.
Adjustment for safer driving
When the air conditioning is switched on, the temperature and the air
humidity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With Climatic
xDisable air recirculation mode Ÿpage 185.
xSet the fan to setting 1 or 2.
xTurn the temperature control to the centre position.
xOpen the air outlets in the dash panel Ÿpage 185.
xTurn the air distribution control to the required position.
xPress the button to turn on cooling. The button will light up.
With Climatronic
xPress the button.
xSet the temperature to +22 °C (+72 °F).

Climatronic: press the button to use residual heat. When
the engine is still warm but the ignition switched off, the heat
given off by the engine can be used to keep the passenger
compartment warm. The button will light up when the
function is switched on. The function will switch off after
around 30 minutes and if the battery level is low.
p
Climatronic: transferring the driver's seat temperature settings
to the other seats. If the button is not lit up, the set tem-
perature in the driver's seat will also apply to the other seats.
Press the button or the temperature control for the front pas-
senger's seat or the rear seats to set them to a different tem-
perature. The button lights with an indicator.
Vehicles with auxiliary heating: observe the description of the
button.

Checking programming
If the timer has been switched on after switching the ignition off, the instant
on button will remain lit for around ten seconds.
WARNING
Never program the independent heating system to be activated and oper-
ated in closed, unventilated areas. The auxiliary heater fumes contain carbon dioxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
User instructions
The auxiliary heater exhaust system located below the vehicle must be kept
clear of snow, mud and other objects. The exhaust fumes must not be
obstructed in any way. The exhaust fumes generated by the auxiliary heater
are removed via an exhaust pipe fitted underneath the vehicle.
On heating the vehicle interior, depending on the outside temperature the
warm air is first directed at the windscreen and then to the rest of the
passenger compartment through the air vents. If the air vents are turned
towards the windows, for example, the form of air distribution may be
affected.
Depending on the outside temperature, the temperature at which the auxil-
iary heater warms the vehicle interior may be somewhat higher if the heating
or climate control temperature control is set to maximum before switching the
heating on.
Depending on the engine, vehicles with auxiliary heater may be fitted with a
second battery in the luggage compartment that is responsible for powering
the auxiliary heater.
Cases in which the auxiliary heater will not switch on
xThe auxiliary heater requires about as much power as the dipped head-
lights. If the battery charge is low, the auxiliary heater will switch off automat-
ically or will not even switch on. This avoids problems when starting the
engine.
xThe heater will switch just once each time. The timer will also have to be
switched back on every time it is required.
