matically turns off after approximately 10 minutes. NOTE:
•You can turn off the heated mirror feature at anytime
by pushing the rear window defroster switch a second
time.
• To prevent excessive battery drain, use the rear win-
dow defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a
mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.

9. Recirculation Control ButtonPush this button to choose between outside air
intake or recirculation of the air inside the ve-
hicle. An indicator light will illuminate when
you are in Recirculation mode. Only use the
Recirculation mode to temporarily block out any outside

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Maintenance Procedures” in “Maintaining Your Ve-
hicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended, because it may cause window fogging.
