Air intake  
Air conditioning  
Make sure that the exterior air inlet  
grille at the base of the windscreen  
is clean (free of dead leaves, snow  
etc.).  
If washing the vehicle with a high  
pressure jet, take care to avoid  
targeting close to the air inlet.  
At any time of year, the air condi-  
tioning is useful for removing air  
humidity and misting.  
To keep the air conditioning com-  
pressor well sealed, it is essential  
to operate the air conditioning at  
least once in every month.  
III  
To be effective, the air condition-  
ing should only be used with the  
windows closed.  
If you are towing a heavy trailer or  
if outside temperatures are very  
high, the air conditioning may be  
temporarily interrupted in favour  
of engine cooling.  
Water arising from condensation  
in the air conditioning is allowed  
to drain out through an aperture  
provided for this purpose ; a pool  
of water may thus form beneath  
the vehicle when stationary.  
You are recommended to have the  
airconditioningsystemcheckedon  
a regular basis (see Maintenance  
Guide).  
Air vents  
Sensor  
The air vents have grilles for  
directing the flow of air (up/down,  
right/ left) with controls for adjust-  
ing the volume of air.  
The automatic air conditioning  
inside the passenger compartment  
makes use of the sunlight sensor,  
which is located on the dashboard  
behind the instrument panel.  
Air circulation  
Optimal comfort is obtained by a  
good distribution of air in the front  
and the rear of the passenger  
compartment.  
To ensure efficient operation, take  
care not to obstruct the air outlets  
located under the front seats.  
Take care not to obstruct it.  
Pollen filter / odour filter  
(active carbon)  
Your installation has a filter for  
excluding dust and restricting  
disagreeable odours.  
This filter needs to be changed  
according to the maintenance  
requirements. (See: Maintenance  
Guide).  
The air conditioning uses energy  
from the engine to operate. This  
results in extra fuel consumption
