GMC 15919282 Automobile User Manual


 
@ (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
40°F (4°C). 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 Air
Conditioning and Heating System on
page 3-31 or Rear Air Conditioning
and Heating System and Electronic
Climate Controls on page 3-32.
Rear Window Defogger
The rear window defogger uses a
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 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.
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.
