1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level
mode.
4. Set the air intake control to the
recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed.

NOTICE
When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature 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 the
recirculated air to the fresh outside
air position.
• 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 win-
dows and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
