NOTICE
When using the air conditioning system,
monitor the engine temperature gauge
closely while driving up hills or in heavy
traffic when outside temperatures are
high. Air conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn the air
conditioning system off if the engine
temperature gauge indicates engine
overheating.
Air conditioning system operation tips

[If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.

[After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.

[To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.

[Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.

[If you operate air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection to the

position and fan speed control to the
lowest speed.
