Rear Window Washer/Wiper (Option) You control the rear window washer/wiper using a switch located on the instrument panel, next to the audio system. For delay wiping, slide the switch up to the center position next to the word DELAY on 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 and then return to the setting that was chosen before the lever was pushed. Move the switch to OFF to turn off the rear window washer. The rear window washer uses the same fluid bottle as the front windshield washer. If the fluid level is low in 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. To turn the wiper on, slide the switch all the way up to ON. 2-37
