Rainsense t Wipers (If Equipped) 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. Your vehicle may be equipped with Rainsense windshield wipers. When active, these wipers are able to detect moisture on the windshield and automatically turn on the wipers. The moisture sensor is located next to the inside rearview mirror and is mounted on the windshield. To turn on the Rainsense feature, the wipers must be set to one of the five delay settings on the multifunction lever. Each of the five settings adjusts the sensitivity of the rainsensor. For more wipes, select the higher settings; for fewer wipes, select the lower settings located closer to off on the multifunction lever. The rainsensor will automatically control the frequency of the wipes from off to high speed according to the weather conditions. The wipers can be left in a rainsense mode even when it is not raining. 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. NOTICE: Turn the multifunction lever to off to avoid wiper damage when going through an automatic car wash. 2-41
