Air vents At least one air vent must be open while
cooling 3 (air conditioning compressor) is
on in order to prevent the evaporator from
icing up due to lack of air movement.
Pleasant ventilation to the head area
controlled by the position of the
temperature switch.
To increase the air supply, set the fan to a
higher speed and set the air distribution
switch to M or L.

Centre and side (1) air vents
To open vent: rotate wheel upwards.
Adjust the direction of air flow by rotating
the horizontal and vertical wheels.
To close the vents rotate the wheel fully
downwards. Windscreen defros

Air distribution switch set to V or J : Air is
directed onto the windscreen and door
windows.
Additional vents
are beneath the windscreen and side
windows and in the front footwell.

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.
Picture no: 14145s.tif
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 head area:
set air distribution switch to M and open
all vents.
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 Set air distribution switch to desired
position, preferably position J, 3 116. 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 stratifica tion of temperature
with a pleasant "cool head and warm feet"
effect, set the rotary air distribution switch
to K, J or L, set temperature rotary
switch to any position (in centre range with
temperature stratification effect).

Demisting and defrosting windows
Misted or icy windows, e. g. due to damp
weather, damp clothing or low outside
temperatures:
z Turn the temperature switch clockwise as
far as it will go (warm). z
Set fan to 3 or 4 .
z Set air distribution switch to V.
z Switch on heated rear window Ü 3.
z Open side air vents as required and
direct them towards door windows.
z For simultaneous footwell heating, set
air distribution switch to J.
9 Warning
Disregard of the instructions could lead
to misting or icing of the windows and
subsequent accidents due to impaired
visibility.

Air 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: 14159s.tif
Cooling n
Only operate with the engine and fan
running. Activate and deactivate with
the nbutton.
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: 14158s.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.

120 Climate controlAir distribution to V: the air recirculation
system is automatically switched off to
speed up window demisting and prevent
fogging.
Picture no: 14160s.tif
Comfort setting
z Set cooling n as desired.
z Air recirculation system 4 off.
z Set temperature switch as desired.
z Switch on fan at desired speed.
z Set air distribution switch to M or L.
z Open or adjust vents as required. Temperature switch in centre of
adjustment range: warmer air will flow into
the foot well and cooler air into the upper
zone, with warmer air coming from the side
air vents and cooler air from the centre
vents.
9 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
compartment air deteriorates which
may cause the vehicle occupants to feel
drowsy.

if there is still moisture in the system after
previous air conditioning operation, the
windows may mist up. To prevent this,
set air distribution to K before starting
engine and set to V approx. 5 seconds
after starting.
z Activate heated rear window Ü.
z Open side air vents as required and
direct them towards the side windows.
9 Warning
Disregard of the instructions could lead
to misting or icing of the windows and
subsequent accidents due to impaired
visibility.

122 Climate controlElectronic 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.
Picture no: 16500s.tif
Temperature changes due to external
influences, such as direct sunlight, are
automatically compensated.
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:
When set to automatic mode, the climate
control system provides the optimal
settings for almost all conditions. If
necessary, climate control 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 automatically at low outside
temperatures.

Automatic mode
Basic setting for maximum comfort:
zPress AUTO button.
z Open all air vents.
z Switch on AC compressor 3125.
z Preset temperature to 22 C with turn
knob.
The temperature can be set higher or lower
as desired. Switching off the air conditioning
compressor (
ECO appears in display) can
have a detrimental effect on comfort and
safety 3125.
All air vents are actuated automatically in
automatic mode. The air vents should
therefore always be open 3115. Temperature preset
The left rotary knob can be used to set the
temperature to values of between 16 C
and 28 C.
For the sake of comfort, only change the
pre-selected temperature in small steps.
If the temperature setting is less
than 16 C,
LO appears in the air
conditioning display: the climate control
system runs constantly at maximum
cooling power, and the temperature is not
regulated.
If the temperature setting is
above 28 C, HI appears in the air
conditioning display: the climate control
system runs constantly at maximum
heating power, and the temperature is not
regulated.
The temperature settings remain stored
when the ignition is turned off.

124 Climate controlManual settings
Under certain circumstances (e.g. iced or
misted windows), the functions of the
climate control system can be modified
manually.
Manual settings are saved when the
ignition is switched off.
Make manual settings as follows when
necessary:
Picture no: 16501s.tif
Window demisting and defrosting
Misted or icy windows, e. g. due to damp
weather, damp clothing or low outside
temperatures:
Press button V, V appears in the air
conditioning display. Temperature, air dist
ribution and blower
are set automatically.
To return to automatic mode: press
button V or AUTO .
