recirculates air inside the passenger
compartment and prevents outside
air from entering the vehicle.The quality of the passenger
compartment air may decrease
since the amount of outside
air entering the vehicle is reduced.
When the recirculation mode is
used without air conditioning, the
air humidity increases, and the
windows may fog. Avoid using the
recirculation mode during high
periods of humidity or cool outside
temperatures since this may result in
increased window fogging. If window
fogging is experienced, select the
defrost mode.
Rear Window Defogger

rear window.
The rear window defogger will only
work when the ignition is in

defogger on or off. An indicator
light inside the button will be lit

they turn on when the rear window
defogger button is pressed. Press
the button again to turn them off.
For more information, seeOutside
Power Mirror(s) on page 2-12.
The rear window defogger will stay
on for approximately 15 minutes
after the button is pressed, unless
the ignition is turned off.
Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.
