5-4 Instruments and Controls Heavy snow or ice can overload the wipers. A circuit breaker stops them until the motor cools. Wipe Parking If the ignition is turned to LOCK/ OFF while the wipers are on 1, 2, or 3, they will immediately stop. If the windshield wiper lever is then moved to 9 before the driver door is opened, or within 10 minutes, the wipers will restart and move to the base of the windshield. If the ignition is turned to LOCK/ OFF during a windshield wash, the wipers will stop when they reach the base of the windshield. Windshield Washer Pull the windshield wiper lever toward you to spray windshield washer fluid and activate the wipers. The washer and wipers will continue until the lever is released or the maximum wash time is reached. When the windshield wiper lever is released, additional wipes may occur depending on how long the windshield washer had been activated. See Washer Fluid on page 10‑22 for information on filling the windshield washer fluid reservoir. 3 (Adjustable Interval Wipes): Move the lever to 3, then turn the band up for more frequent wipes or down for less frequent wipes. 9 (Off): Use to turn the windshield wipers off. 3 (Mist): Briefly move the wiper lever down for a single wipe or hold down for several wipes. Clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. Damaged wiper blades should be replaced. See Wiper Blade Replacement on page 10‑29. { WARNING In freezing weather, do not use the washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.
