The air conditioning compressor will operate in all modes except FLOOR
and VENT. It will also operate only when required when AUTOMATIC
has been selected. However, the air conditioning will only function if the
outside temperature is about 10°C (50°F) or above.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
Under normal conditions, your vehicle's climate control system should be
left in any position other than MAX A/C or OFF when the vehicle is
parked. This allows the vehicle to "breathe" through the outside air inlet
duct.
