Be sure to clear ice and snow from the wiper blades before using them. If they're frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. Rear Window Washer/Wiper (Option) You control your rear window washer/wiper from a switch located on your instrument panel, next to the audio system. Windshield Washer At the top of the multifunction lever, there's a paddle marked with the windshield washer symbol and PUSH. To spray washer fluid on the windshield, press the paddle. 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. The wipers will clear the window and then either stop or return to your preset speed. 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 and then return to the setting that was chosen before the lever was pushed. 2-36
