Operating tips
Clear snow and ice from the wiper blade
and air inlet in front of the windshield.
This will improve heater operation.

malfunctioning, it is only the system motors
and solenoids switching from one outlet to
another.AIR CONDITIONER OPERATIONStart the engine, move the fan control dial to the

Operating tips
Keep windows and sun roof closed while theair conditioner is in operation.

After parking in the sun, drive for two or three
minutes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This will allow the air
conditioner to cool the interior more quickly.

The air conditioning system should be
operated for about ten minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubri-
cation.

If the coolant temperature gauge exceeds the
hot position, turn the air conditioner off. For
additional information, see “If your vehicle
overheats” in the “6. In case of emergency”
section.
