Rear Wiper Arm Assembly Protection

When using an automatic car wash, move the rear wiper switch to OFF to turn off the rear wiper. On some vehicles, if the shift lever is in N (Neutral) and the vehicle speed is very slow, the rear wiper will automatically park.

Wiper operation returns to normal when the transmission is no longer in N (Neutral) or the vehicle speed increases.

Reverse Wipers

If the rear wiper control is off, the rear wiper will operate automatically whenever the transmission is in R (Reverse) and the front wiper is on LO or HI. If the rear wipers are off, the transmission is in R (Reverse), and the front wipers are on intermittent, the rear wiper will automatically perform intermittent wipes.

This feature can be turned on or off. Refer to Vehicle Personalization.

The washer fluid reservoir is used for the windshield and rear window. Check the fluid level if either washer does not operate. Refer to Washer Fluid 0 307.
