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.
The wiper operations return to normal when the transmission is no longer in N (Neutral) or the vehicle speed has increased.
Reverse Gear Wipes
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 interval wipes, then the rear wiper automatically performs interval wipes.
This feature can be turned on or off. See Vehicle Personalization.
The windshield washer reservoir is used for the windshield and rear window. Check the fluid level if either washer is not working. See Washer Fluid 0 307.
