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
approximately 20 minutes after the button is pressed. If
turned on again, the defogger will run for the same
amount of time. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice: Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t 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 3-25 and Scheduled Maintenance
on page 6-4.
