You control your rear
window washedwiper
from a switch on your
instrument panel, next to
the audio system.
To turn the wiper on, slide the switch all the way up.
For delay wiping, slide the switch even with the word
DELAY in the center position of the rear wiper control.
The wiper will cycle every nine seconds.
To wash the window, push in on the switch. Window
washer fluid will continue to spray until the switch is
released. The wiper will continue with three more wipes

the washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not your
rear window, check the fluid level.
