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.

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.

Climate control
Auxiliary heater Depending on outside temperature and
engine temperature, the passenger
compartment of vehicles with Quickheat 3
electric auxiliary heating is warmed up
more quickly.
Diesel-engined vehicles have a fuel-
powered auxiliary heater 3.
Picture no: 14147s.tif
Air intake The air intakes in front of the windscreen on
the far right and left sides of the engine
compartment must be kept clear to allow
air intake. Remove any leaves, dirt or snow. Air outletDo not cover the air outlets when storing
items in the luggage compartment storage
compartments.
Pollen filter The pollen filter cleans dust, soot, pollen
and spores from the air entering from
outside. The active carbon layer 3
eliminates most odours and noxious
environmental gases from the air.

128 Climate controlRegular operationFor consistently good operation, the air
cooling system 3 must be switched on for
several minutes once per month regardless
of the weather and the time of year.
Operation not possible with the cooling
system switched on and when the outside
temperature is low.
Service For optimal cooling performance, we
recommend that the climate control
system be checked annually, starting three
years after initial vehicle registration.
