The rear window washer/wiper switch is located in the instrument panel switchbank. See Instrument Panel Switchbank .

(Rear Intermittent Wiper): Press the wiper symbol on the top of the switch to turn on the intermittent wiper. To turn off the wiper, gently press the bottom of the switch.

(Rear Wiper/Washer): To wash and wipe the rear window, press the washer symbol on the bottom of the switch. Washer fluid will spray as long as the switch is held in. When the switch is released, the wiper will continue to cycle three more times. There is only one washer fluid reservoir for the front and rear windshield wipers. See Windshield Washer Fluid .

To wash the rear window while the rear wiper is already on, press the bottom of the switch. Press the top of the switch to continue the intermittent wiper cycle after the washing cycle is completed.

The rear window washer uses the same fluid bottle as the windshield washer. However, the rear window washer will run out of fluid before the windshield washer. If you can wash your windshield but not your rear window, check the fluid level.

Remember that a damaged wiper blade may prevent you from seeing well enough to drive safely. To avoid damage, carefully clear ice and snow from the wiper blade before using it. If it is frozen to the windshield, carefully loosen or thaw the wiper blade. If your blade becomes damaged, get a new blade or blade insert.

Caution: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.
