Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If the blades do become damaged, get new blades or blade inserts. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload. Your vehicle is equipped with wiper-activated headlamps. After the windshield wipers have been on for approximately six seconds, the headlamps will automatically turn on. See Wiper Activated Headlamps under Exterior Lamps on page 3-16 for more information. The Rainsense™ system can be activated by turning the wiper band to one of the five sensitivity levels indicated on the wiper stalk. The position closest to OFF is the lowest sensitivity setting, level one. This allows more rain or snow to collect on the windshield between wipes. Turning the wiper band away from you to higher sensitivity levels increases the sensitivity of the system and frequency of wipes. The highest sensitivity setting, level five is closest to LO. A single wipe will occur each time you turn the wiper stalk to a higher sensitivity level to indicate that the sensitivity level has been increased. Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash. The MIST and wash cycles operate as normal and are not affected by the Rainsense™ function. The Rainsense™ system can be overridden at any time by manually turning the wiper band to LO or HI speed. When Rainsense™ is active, the headlamps will turn on automatically. The headlamps will turn off again once the wipers turn off if it is light enough outside. If it is dark, they will remain on. See " Wiper-Activated Headlamps" under Exterior Lamps on page 3-16 for more information. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the moisture sensor. Doing this could cause the moisture sensor to malfunction. Rainsense™ II Wipers If your vehicle has this feature, the moisture sensor is mounted on the interior side of the windshield behind the rearview mirror. It is used to automatically operate the wipers by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on driving conditions and the sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes will occur more frequently. The Rainsense™ wipers operate in a delay mode as well as a continuous low or high speed as needed. If the system is left on for long periods of time, occasional wipes may occur without any moisture on the windshield. This is normal and indicates that the Rainsense™ system is activated. 3-12
