Air Conditioning
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.
For quick cool
-down on very hot days, use the
maximum mode setting with the temperature knob all
the way in the blue area. If this setting is used for long
periods of time, the air in your vehicle may become too
dry. The best cool down happens if you start in one of
the other modes and then switch to maximum.
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.
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. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor 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 ducts.
Your vehicle has heat ducts 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
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
defrost with the temperature knob all the way in the red
area. To warm passengers while keeping the windows
clean, use defog.
To defog the side windows, set the right control to
bi
-level and the fan control to the highest setting.
