The air conditioning removes moisture from the air, so
you may notice water dripping from under the vehicle
when it is idling or after it has been turned off.
This is normal.
Heating
The heater works best if you keep the windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob
(on a manual climate control system) is all the way in
the red area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum heating is required.
The BI
-LEVEL setting is designed for use on sunny
days when the air is only moderately warm or cool.
On days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. The BI-LEVEL setting will direct cooler
airflow to your upper body and warmer air to the
floor area.
If you have the optional engine coolant heater and use it
during cold weather 0 F (
-18 C) or lower, the heating
system will provide heat more quickly because the
coolant is already warmed. See “Engine Coolant Heater”
in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, the FRONT defrost
mode (Automatic Electronic Dual Climate Control
System) or defrost mode (manual control system)
should be used and the fan speed should be adjusted to
the highest speed. With the manual control system, turn
the temperature control knob all the way to the red area.
To keep the windshield clear and provide heated air to
the floor area of the vehicle, use the DEFOG setting.
Your vehicle is equipped with side window defogger
vents located near the side rearview mirrors.
Rear Window Defogger
REAR: This button turns the rear defogger and the
optional heated outside mirrors on. The light on the
button will come on when operating. The system
automatically shuts off after approximately 10 minutes.
If further defogging is desired, press the button again
and it will operate for about five more minutes.
The rear window defogger operates only when the
engine is running.
