x (Delay Adjustment): Use this band to set the length of the delay between wipes when using the delay feature. The closer the band is moved toward mist, the longer the delay. The windshield wiper lever must be in delay for this feature to work. (Low Speed): For slow, steady wiping cycles. Rainsense™ II Wipers For vehicles with 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. To activate the Rainsense system, turn the wiper band to delay mode and select one of the four 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 four, is closest to low. A single wipe occurs each time the wiper stalk is turned to a higher sensitivity level to indicate that the sensitivity level has been increased. 6 1 (High Speed): For rapid wiping cycles. If the windshield wipers are in use for about six seconds while you are driving, the exterior lamps will come on automatically if the exterior lamp control is in AUTO. See Wiper Activated Headlamps on page 3-36 for more information. Clear snow and ice from the wiper blades before using them. If the blades are frozen to the windshield, loosen or thaw them. If they become damaged, install new blades. For more information, see Windshield Wiper Blade Replacement on page 5-52. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. For STS-V, the vehicle is equipped with a feature that disables the wiper system when the hood is open and the vehicle is stopped. Opening the hood will automatically park the wipers if they are not parked. 3-14
