Driving your vehicle
✽ ✽ NOTICE
• When using the air conditioning sys-
tem, monitor the temperature indica-
tor closely while driving up hills or in
heavy traffic when outside tempera-
tures 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 temperature indicator
indicates engine overheating.
• When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.

Air conditioning system opera-
tion 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 win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed at idle
as the air conditioning
cycles. This is a normal system opera-
tion characteristic.
• Use the air conditioning system every
month if only for a few minutes to
ensure maximum system perform-
ance.
• When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
• The air conditioning system includes a
function that automatically turns the air
conditioning compressor off if engine
coolant temperature approaches an
over heating level. The air conditioning
compressor operation will resume
once engine coolant temperature
returns to the normal range. Also, the
air conditioning compressor is auto-
matically turned off for a few seconds
when the accelerator is fully depressed
(wide open throttle).
• When operating the air conditioning
system use the outside (fresh) air
compressor
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.
