Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
(Rear): Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light above
the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off approximately
15 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
seven minutes before turning off. If the vehicle is moving
faster than 50 mph (80 kph), the rear defogger will
stay on. The defogger can also be turned off by pressing
the button again or by turning off the engine.
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 your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Use the thumbwheels located next to and below the air
outlets to change the direction of the airﬂow and to
open and close the outlets.
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ﬂow of air into your vehicle.
Use of non-GM approved hood deﬂectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment ﬁlter. The ﬁlter removes certain particles
from the air, including pollen and dust particles.
Reductions in airﬂow, which may occur more quickly in
dusty areas, indicate that the ﬁlter needs to be
