Rear Wiper Arm Assembly Protection
When using an automatic car wash, move the
rear wiper control to OFF to disable the rear
wiper. In some vehicles, if the transmission is
in N(Neutral) and the vehicle speed is very
slow, the rear wiper will automatically park
under the rear spoiler.
The wiper operations return to normal when
the transmission is no longer in N(Neutral) or
the vehicle speed has increased.

If the rear wiper control is off, the rear wiper
will automatically operate continuously when
the transmission is in R (Reverse), and the front
windshield wiper is performing low or high
speed wipes. If the rear wiper control is off, the
transmission is in R(Reverse), and the front
windshield wiper is performing INT wipes, then
t
he rear wiper automatically performs INT
wipes.
This feature can be turned on or off. See “Auto
Wipe in Reverse Gear” under Settings > Vehicle
>Comfort and Convenience >Auto Wipe in
