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
