4–10 HEATING & AIR CONDITIONING
AIR OUTLETS
To open an outlet, press on its cover.
Rotate the cover to direct airflow as
desired.
OPERATING TIPS
• Before using the air conditioning sys-
tem, open the windows for a few min-
utes to permit hot air to escape if the
vehicle has been parked in direct sun-
light.
• For maximum cooling, select the venti-
lation mode and the highest fan speed.
Make sure that the air conditioning
compressor is turned on. Then rotate
the temperature control knob to select
the coolest temperature and select the
recirculation mode.
• To defog the windows on rainy days
or in high humidity, turn on the air
conditioning compressor.
• Turn on the air conditioning for a few
minutes at least once a week, even in
the winter or when the air conditioning
system is not being used regularly. This
maintains proper lubrication of the
compressor and seals, prolonging the
service life of the system.
• Driving in stop-and-go traffic may
reduce the effectiveness of the air
conditioning system.

conditioner on or off.

the efficiency of the defroster.
• Do not use the heating/defogging mode
or the defrosting mode in extremely
humid weather when the temperature
control is set to cold.
