Using recirculation for long periods
of time could cause the air inside
of the vehicle to become too dry.
To prevent this from happening,
after the inside of the vehicle has
cooled, turn the recirculation
mode off.
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, defrost, or defogging
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4°C (40°F). 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.
REAR (Rear Climate Control):
Press to turn the rear heating and
air conditioning on or off. See Rear
Climate Control System (Rear
Climate Control Only) on page 8 10
or Rear Climate Control System
(Rear Climate with Rear Seat Audio)
on page 8 11.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
Climate Controls
<
(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear window
defogger stays on for about
10 minutes, before automatically
turning off. The defogger will
also turn 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 is pressed.
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.
