Heating and ventilation system Temperature
Adjusted using left-hand rotary switch.
The amount of heat is dependent on the
coolant temperature and is thus not fully
attained until the engine is warm.

Air flow
Adjusted using centre rotary switch.
The rate of air flow is determined by the
fan. The fan should therefore also be
switched on during a journey.

Ventilation
zSet the temperature to the desired
setting.
z Switch fan on, select fan setting
according to requirements.
z For maximum ventilation in the head
area: set the air distribution switch to M,
open all air vents, direct the air vent slats
3 122.
z For ventilation to foot well: Set air
distribution switch to K.
z For simultaneous ventilation to the head
area and the foot well: Set air
distribution switch to L. Heating
For rapid warming of the passenger
compartment:
z
Turn the temperature switch clockwise as
far as it will go (warm).
z Set the fan to speed 3.
z Open air vents.
z Set air distribution switch to desired
position, preferably position J, 3 123. The comfort and general well-being of the
vehicle occupants are to a large extent
dependent on a suitab
le ventilation and
heating setting.
To achieve temperature layering with the
pleasant effect of "cool head and warm
feet", set the air distribution rotary switch
to K or J and move the rotary
temperature switch to any position you like
(with temperature strati fication effect in
the centre zone).

126 Climate controlAir conditioning system
3
As a supplement to the heating and
ventilation system, the air conditioning
system cools and dehumidifies (dries)
inflowing air.
If cooling or dehumidification is not
desired, switch off cooling in order to save
fuel.
Cooling switches off automatically at low
outside temperatures.
Picture no: 18213s.tif
Cooling n
Only operate with the engine and fan
running. Activate and deactivate with
the n button.
When cooling is active (AC compressor) the
air is cooled and dehumid ified. If cooling or
dehumidification is not desired, switch off
cooling in order to save fuel.
Cooling switches off automatically at low
outside temperatures.
When cooling operates, condensation
forms and drips from the underside of the
vehicle.
Picture no: 18214s.tif
Air recirculation system 4
The air recirculation mode of the
ventilation system is activated and
deactivated by pressing the 4 button.
If fumes or unpleasant odours penetrate
from outside: temporarily switch on air
recirculation system 4.
To increase cooling at high outside
temperatures, switch on the air
recirculation system briefly.

Warning
The air recirculation system minimises
the entry of outside air. The humidity
increases, and the windows can mist up.
The quality of the passenger compart-
ment air deteriorates which may cause
the vehicle occupants to feel drowsy.

Electronic climate control system
3
Provides a the greatest amount of comfort
in the interior regardless of the weather,
outside temperature or season.
To ensure a constant and comfortable
climate in the vehicle, the temperature of
the inflowing air, the air-flow rate and the
air distribution are changed automatically
according to climatic conditions outside
the vehicle.
The climate is regulated automatically
based on personal settings.
Temperature changes due to external
influences, such as direct sunlight, are
automatically compensated.

Climate control
Data is shown on the information display.
Setting modifications are briefly shown in
the information display, superimposing
over the currently displayed menu.
May appear differently depending on the
type of display 394.
The climate control system settings are
stored in the vehicle key when the vehicle is
locked, see "Personalised key" 339.
Different settings are stored for each
remote control. Use of a remote control will
activate the settings associated with it.
Picture no: 18205s.tif
Manual settings such as operating without
cooling and air distribu tion can be selected
using the menu 3132.
When cooling (air conditioning
compressor) is active, air is cooled and
dehumidified.
The pollen filter removes dust, soot, pollen
and spores from the inflowing outside air.
Picture no: 18483s.tif
When set to automatic mode, the climate
control system provides the optimal
settings for almost all conditions. If
necessary, climate cont rol system settings
can be modified manually.
The climate control system is only
operational when the engine is running.
If you wish the climate control system 3 to
operate correctly, do not cover the sensor
on the instrument panel.
Cooling (air conditioning compressor)
switches off automati cally at low outside
temperatures.
