Windshield Washer There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed. Rear Window Washer/Wiper This switch is located on the instrument panel. CAUTION: In freezing weather, don't use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision. To turn the rear wiper on, turn the switch to either 1 or 2. For long delayed wiping, turn the switch to 1. For short delayed wiping, turn the switch to 2. To turn the wiper off, turn the switch to 0. To wash the window, press the knob. 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 windows, check the fluid level. 2-39
