(switch indicator ON), then set the
fan speed control knob to the highest
speed.
✻
NOTICE
When using the air conditioning
system with high outside air tem-
peratures, monitor the temperature
gauge closely while driving up long
hills or in heavy traffic. Air condi-
tioning system operation may cause
engine overheating. Continue to use
the blower fan but turn the air con-
ditioning system off if the tempera-
ture gauge indicates engine over-
heating.

DRIVING YOUR VEHICLE
4-52AIR CONDITIONING
SYSTEM OPERATING
TIPS:• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time to
let hot air inside the vehicle escape.
• To help reduce moisture on the inside
of windows on rainy, humid days,
decrease the humidity inside the
vehicle by operating the air
conditioning system.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed at idle as the A/C compressor
cycles ON. This is a normal system
operating characteristic.
• Use the air conditioning system every
month if only for a few minutes.
• After air conditioning system use,
you may notice clear water dripping
(or even puddling) on the ground
under the passenger side of the
vehicle. This is a normal system
operating characteristic.• The air conditioning system includes
a function that will automatically turn
the A/C compressor OFF if engine
coolant temperature approaches an
overheating level. A/C compressor
operation will resume once engine
coolant temperature returns to the
“normal” range. Also, the A/C
compressor is automatically turned
off for a few seconds when the
accelerator is fully depressed.
• When operating the air conditioning
system use the outside (fresh) air
position.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

(IF EQUIPPED)Whenever the ventilation controls are in

When using AQS mode, AQS(Air
Quality Control System) automatically
senses outdoor air pollutants and
minimizes them from entering the
vehicle, however, unpleasant or foul
odors that might be present may still be
noticeable within the vehicle.
CAUTION
 Prolonged driving with “Air
Quality Control System” ON
will cause frosting inside the
vehicle.
 To defrost the vehicle, set the
mode selection knob to Defrost
( ) position or the air intake
button to the outside position.
 The air quality control sensor is
located at the side of the radia-
tor. Be careful to avoid damag-
ing the sensor.
