yellowblue Air Conditioning The air conditioner and heater work best if you keep your windows closed while using them. Your vehicle also has the flow-through ventilation system described later in this section. On very hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down, which should help fuel economy. On cool, but sunny days, the sun may warm your upper body, but your lower body may not be warm enough. You can use BI-LEVEL with the temperature knob in the middle and the A/C button pushed in. The system will bring in outside air and direct slightly warmer air to your lower body. For quick cool-down on very hot days, use VENT with the temperature knob all the way in the blue area and the A/C and RECIRCULATION buttons pressed. If this setting is used for long periods of time, the air in your vehicle may become too dry. For normal cooling on hot days, use VENT with the temperature knob in the blue area and the A/C button pushed in. The system will bring in outside air and cool it. Heating On cold days, use FLOOR and the outside air button with the temperature knob all the way in the red area. The system will bring in outside air, heat it and send it to the floor outlets. Your vehicle has heat outlets that are directed toward the rear seat. Keep the area under the front seats clear of obstructions so the heated air can reach the rear seat passengers. If your vehicle has an engine coolant heater, you can use it to help your system provide warm air faster when it's cold outside (0_F (-18_C) or lower). An engine coolant heater warms the coolant your engine and heating system use to provide heat. See "Engine Coolant Heater" in the Index. Defogging and Defrosting Windows Your system has two settings for clearing the front and side windows. For each setting, adjust the temperature control as desired. To defrost the front window quickly, turn the temperature control knob all the way in the red area. Use DEFROST and adjust the fan to the highest speed.

The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow

through ventilation system described
later in this section.
On very hot days, open the windows long enough to
let hot inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI

the middle and the A/C button pushed in. The system
will bring in outside air and direct slightly warmer air to
your lower body.
For quick cool
-
down on very hot days, use VENT with
the temperature knob all the way in the blue area and the
A/C and RECIRCULATION buttons pressed. If this
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature knob in the blue area and the A/C button
pushed in. The system will bring in outside air and
cool it.
Heating
On cold days, use FLOOR and the outside air button
with the temperature knob all the way in the red area.
The system will bring in outside air, heat it and send it to
the floor outlets.
Your vehicle has heat outlets that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside (0
F (
-
18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, turn the temperature
control knob all the way in the red area. Use DEFROST
and adjust the fan to the highest speed. To warm
passengers while keeping the front window clean,
use DEFOG.
