The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off.
An indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must
be re‐selected when the engine is
turned on again.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle. The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning compressor also comes
on when this mode is activated.
While in recirculation mode the
windows can fog when the weather
is cold and damp. To clear the fog,
select either the defog or defrost
mode and increase the fan speed.

warming grid to remove fog from the
rear window.
<(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear
window defogger stays on for
about 10 minutes, before turning
off. The defogger also turns off
when the engine is turned off.
Do not drive the vehicle until
all the windows are clear.
For vehicles with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when the rear window
defog button is pressed.
Notice: Do not use a razor blade
or sharp object to clear the inside
rear window. Do not adhere
anything to the defogger grid
lines in the rear glass. These
actions may damage the rear
defogger. Repairs would not be
covered by your warranty.
