Introduction
Viewing Climatronic information
On the screen of Climatronic control unit and on the screen of the factory-
fitted Easy Connect system, the theoretical values of the temperature zones
are shown.
The unit of temperature measurement can be changed in the Easy Connect
system.
Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the air taken into the vehicle interior.
The dust and pollen filter must be changed regularly so that air conditioner
performance is not adversely affected.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule.
Additional information and warnings:
● Easy Connect system
● Seat functions
● Windscreen wipers and washers
● Caring for and cleaning the vehicle exterior
WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● Always ensure that all windows are free of ice and snow, and that
they are not fogged, so as to maintain good visibility of everything out-
side.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, fresh air system, air
conditioner and the heated rear window to maintain good visibility to the
outside.
● Never leave the air recirculation on for a long period of time. If the
cooling system is switched off and air recirculation mode switched on,
the windows can mist over very quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is not required.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never leave the fresh air fan turned off or use the air recirculation for
long periods of time; the air in the vehicle interior will not be refreshed. 

Air conditioning
● The cooling system is switched on (the * button lamp is on) and the am-
bient temperature is below +3 °C (+38 °F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
● The cooling system is switched on, the outside temperature is below
+15 °C (+59 °F) and the windscreen wipers are switched on.
Activation/deactivation of automatic air recirculation is done in the air con-
ditioner menu, under Configuration.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required.
CAUTION
Do not smoke when air recirculation is switched on in vehicles with an air
conditioner. The smoke taken in could lie on the cooling system vaporiser
and on the activated charcoal cartridge of the dust and pollen filter, leading
to a permanently unpleasant smell.
Note
Climatronic: Air recirculation mode switches on to prevent exhaust gas from
entering the vehicle interior when it is in reverse and while the automatic
windscreen wash and wipe is working. 
