If your vehicle has the rear window defogger a warming
grid is used to remove fog on the rear window.

(Rear): Press this button to turn the rear window
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is active. The rear window defogger will
automatically turn off approximately ten minutes

If your vehicle has heated mirrors, this button will
activate them.

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

the defogger grid.
