Heating and ventilation system,
air conditioning system
3
Ventilation, heating and cooling 3 are
combined into one unit that is designed to
provide comfort regardless of the season,
weather or outside temperature.
When cooling 3 is activated, the air is
cooled and dried.
The heating unit heats the air as required in
all operating modes depending on the
position of the temperature switch. The air
supply can be adjusted to suit
requirements by means of the fan.
The buttons for cooling n and air
recirculation 4 are only found on
versions with optional air conditioning
system 3.

Offers the greatest comfort in the vehicle
interior regardless of the conditions
outside.
To ensure a uniform and comfortable
climate in the vehicle, the temperature of
inflowing air, air-flow rate and air
distribution are automatically adapted
based on the climate conditions outside
the vehicle and the current temperature of
the vehicle interior.

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

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.

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.

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.

temperatures: z
Cooling n on, the air conditioning
compressor automatically switches itself
off at low outside temperatures (icing).
z Turn the temperature switch clockwise.
z Set fan to 3 or 4 .

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.

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.

Activating and deactivating air
conditioning compressor
Press the ECO button. ECO appears in the
air conditioning display.
Switch on to sa ve fuel. In this m ode cooling
(AC compressor) is switched off.
Inflowing air is neither cooled nor
dehumidified. This restricts the level of
comfort provided by the automatic climate
control system. This may cause the
windows to mist up, for example.
When cooling operates, condensation
forms and drips from the underside of the
vehicle.
To return to cooling operation: press
ECO button. ECO goes out.

Air distribution
Press one or more of the following buttons.
The corresponding symbol appears in the
air conditioning display:
To return to automatic mode: Press the
appropriate buttons again, or press AUTO.

Air flow
Set air flow using the right-hand rotary
knob. The selected fan speed is indicated
by the number of bars.
To deactivate the fan and thereby the
automatic climate control system: Turn the
right-hand rotary knob anticlockwise until
the display goes out.
Switching on: turn rota ry knob clockwise.
To return to automatic mode: Press

Manual air recirculation mode
The air recirculation system prevents the
entry of outside air and the air in the
passenger compartment is circulated. Press button
4, % appears in the air
conditioning display.
To switch off manual air circulation: press
button 4 again.
Picture no: 16507s.tif
Air conditioning with the engine not
running
When the vehicle is stopped and the
ignition off, the residu al heat or cooling in
the system can be used for climate control
in passenger compartment, e.g. when
stopped at a level crossing.
Press AUTO with the ignition off. The
preselected temperature appears in the air
conditioning display. The temperature can
be adjusted with the left-hand rotary knob.
Residual climate control can only operate
for a limited period of time. To cancel,
press the AUTO button.
9 Warning
The exchange of fresh air is reduced in
air circulation mode. The quality of the
passenger compartment air
deteriorates which may cause the
vehicle occupants to feel drowsy. In
operation without cooling the air
humidity increases, so the windows may
mist up. Consequently, the air circulation
system should only be run for short
periods of time.
