✽
✽NOTICE• While using the air conditioning sys-
tem, monitor the engine temperature
gauge closely while driving up hills or
in heavy traffic when outside temper-
atures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the engine temperature
gauge indicates engine overheating.
• Opening the windows in humid weather while air conditioning oper-
ates may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to electri-
cal equipment, air conditioning
should only be used with the windows
closed.
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.
 To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
 During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
 Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
 When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.  Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
 During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.
 If you operate air conditioner exces- sively, the difference between the tem-
perature 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 knob or button
to the position and fan speed con-
trol to the lower speed.
