Outside temperature
A drop in temperature is indicated
immediately and a rise in temperature
after a time delay.
If outside temperatures drop to 3 °C, the symbol : illuminates in the
Triple-Info-Display or the

icy road conditions. : remains
illuminated until temperatures reach
at least 5 °C.
In vehicles with Graphic-Info-Display

Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has:
n=Cooling4=Air recirculationCooling n
Operated with the n button and is
functional only when the engine and
fan are running.
The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Air recirculation system 4
Operated with the 4 button.9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.

is deactivated.

Open slats and adjust direction of air
flow.
To close the vents, direct slats
downwards.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
Service For optimal cooling performance, it isrecommended that the climate control
system be checked annually, starting three years after initial vehicle
registration, including:
■ Functionality and pressure test■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Cleaning of condenser and evaporator drainage
■ Performance check
