Backup Wipe Mode
WARNING: This page is about a different car, the 2007 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
When the transmission gear selector lever is placed in the REVERSE position with the front wiper system turned ON and the rear wiper system turned OFF, the rear washer pump is automatically activated for about 300 milliseconds (0.30 second) and the rear wipers are cycled 3 times. If the transmission gear selector lever is placed in the REVERSE position with the front wiper system and the rear wiper system turned ON, the rear wipers are cycled 3 times without activating the rear washer pump.
