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
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 air conditioning
compressor cycles on. This is a
normal system operation
characteristics.
• Use the air conditioning system
every month if only for a few
minutes.

DRIVING YOUR VEHICLE
• After the use of the air conditioning
system, you may notice clear water
dripping (or even pudding) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristics.
• The air conditioning system includes
a function that will 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
automatically turns 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.
