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

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.
