Jeep 2012 Grand Cherokee - Owner Manual - Manual (Page 277)

Rotate the center portion of the lever upward to the
first detent for intermittent operation and to the
second detent for continuous rear wiper operation.
Rotating the center portion upward once more will
activate the washer pump which will continue to
operate as long as the switch is held. Upon release
of the switch, the wipers will resume the continuous rear
wiper operation. When this rotary control is in the OFF
position, rotating it downward will activate the rear
washer pump which will continue to operate as long as
the switch is held. Once the switch is released it will
return to the OFF position and the wipers will cycle
several times before returning to the parked position.
NOTE: As a protective measure, the pump will stop if
the switch is held for more than 20 seconds. Once the
switch is released the pump will resume normal opera-
tion.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.
If the liftgate flipper glass is open, the rear window
wiper/washer functionality is interrupted and the wiper
stops at that “park” position. When the liftgate flipper
glass is closed, the rear wiper will resume wiper/washer
functionality after five seconds.
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.
