Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<: The rear window defogger will turn off
automatically after it has been activated. The duration
the rear window defogger is on will be longer if the
vehicle is being driven. The defogger can also be turned
off by pressing the button again or by turning off the
engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
rear window defogger buttin is on.
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.
Outlet Adjustment
Use the knob located below or to the side of the outlet,
to change the direction of the air flow.
Operation Tips
• 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 your vehicle more
effectively.
• If the airflow seems low when the fan is at the
highest setting, the passenger compartment
air filter, if equipped, may need to replaced. For
more information, see Passenger Compartment Air
Filter on page 3-23 and Scheduled Maintenance
