H(Vent) Outside Air:This mode directs outside air
to the instrument panel outlets. If you are in city traffic,
and the vehicle is stopped and idling, or the weather is
hot, you may switch from this mode to the recirculation
mode. To prevent the air inside the vehicle from
becoming stale, be sure to return to the vent mode
periodically.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and then directs the remaining
air to the ¯oor outlets. Some air may be directed toward
the windshield. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed to
the ¯oor outlets.

Recirculation
h
(Recirculation):Press this button on the climate
control panel to activate the recirculation mode. With
this selection inside air is recirculated into the vehicle
along with some outside air. This mode reduces outside
air and odors from entering your vehicle. It may also
help to heat or cool the air inside your vehicle more
quickly.
When this button is pressed an indicator lamp to the
right of the button will come on to indicate that the
recirculation mode is on. An adjustment to the
instrument panel brightness control to the highest
setting may be required to see the indicator lamp.
The recirculation mode has a timer. After ®ve minutes,
the system's air inlet door will move slightly to allow
for ten percent fresh outside air to maintain interior air
quality. The only way to reset the system to full
recirculation is to restart the ®ve minute timer by
selecting vent/outside air and recirculation again.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Be sure to
clear as much snow from the rear window as possible.
Notice:Don't use a razor blade or something
else sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and
the repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
=(REAR):Press this button to turn the rear window
defogger on or off.
When this button is pressed an indicator light to the right
of the button will come on to show that the rear window
defogger is active. The instrument brightness control may
have to be adjusted to the highest setting during the
daytime in order to see the indicator light.
The rear window defogger will turn off approximately
20 minutes after the button is pressed. If reselected,
it will run another 20 minutes. The defogger can
be turned off by pressing the button again or by turning
off the engine.
Do not drive the vehicle until all windows are clear.

If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn't come back on, you can drive
normally.
If the warning continues, and you have not stopped,
pull over, stop, and park your vehicle right away.
If there's still no sign of steam, you can idle the engine
for three minutes while you're parked. If you still
have the warning, turn off the engine and get everyone
out of the vehicle until it cools down. Also, see
ªOverheated Engine Protection Operating Modeº listed
previously in this section.

help right away.Cooling System
