Air conditioning
At any time of year, the air condition-
ing 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.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If you are towing a heavy trailer or if
outside temperatures are very high,
the air conditioning may be tempo-
rarily interrupted in favour of engine
cooling.
Sensor
The automatic air conditioning inside the passenger compartment makes use of the sunlight sensor, which is located on the dashboard behind the instrument panel.
Take care not to obstruct it.
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
air conditioning system checked on
a regular basis (see Maintenance
Guide).
The air conditioning uses energy
from the engine to operate. This re-
sults in extra fuel consumption

This system automatically regulates temperature, air fl ow and air distribu-tion in the passenger compartment according to the temperature select-ed (for each side, right and left).
It provides an optimum level of comfort regardless of the climatic conditions, by permanent use of the automatic air conditioning mode (press the AUTO button) and with all the vents open.
Having no airfl ow prevents the air con-ditioning and the system in general from working.
2 - Adjustment of temperature on left hand side
1 - Automatic operation
To display the desired tem-perature, rotate control 2or 3:
AUTOMATIC AIR CONDITIONING
The display HIplay (high) corre-sponds to a demand for max-imum heating (above 27).
The display LO (low) cor-responds to a demand for maximum air conditioning (below 15).
A press on this control, con-fi rmed by the display of "A/C"and "AUTO", automatically manages all the 5 following functions according to the tempera-ture chosen:
- Flow of air.
- Cabin temperature.
- Distribution of air.
- Air conditioning.
- Recycling of air.
To enable the system to operate, all the air vents should be kept open.
3 - Adjustment of temperature on right hand side
- To the left to lower the temperature
- To the right to raise the temperature
The difference between the tem-peratures on the right and on the left cannot be greater than 3.
An adjustment around 21 will provide a temperature that is comfortable. Depending on your requirements, an adjustment between 18 and 24 is normal.
This is the normal operating mode.
To prevent misting of the interior of the vehicle in cold and damp conditions, the use of AUTO mode is recommended.

Notes:
- When you enter the vehicle, the temperature inside the vehicle may be much colder (or warmer) than a comfortable temperature. It is no use modifying the displayed temperature to try to attain the desired level of comfort. The system automatically strives to compensate this temperature discrepancy as rapidly as possible.
- When starting the engine from cold, in order to avoid distributing too much cold air, the blower will attain its optimum level gradually.
