If the liftgate flipper glass is open, connection to the rear
window wiper is interrupted preventing activation of the
rear wiper blade. When the liftgate flipper glass is closed,
the rear wiper switch, or the ignition switch, needs to be
turned OFF and ON to restart the rear wiper.
Rear Window Defroster
The rear window defroster button is located on the
climate control panel. Press this button to turn on
the rear window defroster and the heated outside mirrors
(if equipped). An indicator in the button will illuminate
when the rear window defroster is on. The rear window
defroster automatically turns off after approximately
10 minutes. For an additional five minutes of operation,
press the button a second time.
NOTE: To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
• Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of the
window.
• Keep all objects a safe distance from the window.
