Vacation Storage
Any time you store your vehicle or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Interior fogging on the windshield can be
quickly removed by turning the mode selector
to Defrost. The Defrost/Floor mode can be
used to maintain a clear windshield and pro-
vide sufficient heating. If side window fog-
ging becomes a problem increase blower
speed. Vehicle windows tend to fog on the
inside in mild but rainy or humid weather.
NOTE:
Recirculate without A/C should not be used
for long periods, as fogging may occur.

CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
• Use care when washing the inside of
the rear window. 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 heating elements. Labels can be
peeled off after soaking with warm
water.
• Do not use scrapers, sharp instru-
ments, or abrasive window cleaners on
the interior surface of the window.
• Keep all objects a safe distance from
the window.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter
the plenum, they could plug the water drains.
In winter months, make sure the air intake is
clear of ice, slush, and snow.
A/C Air Filter
The climate control system filters outside air
containing dust, pollen and some odors.
Strong odors cannot be totally filtered out.
Refer to "Dealer Service" in "Servicing and
Maintenance" in your Owner's Manual for
filter replacement instructions.
