You might need to manually disable or cancel the high-beam headlamps by turning the low-beam headlamps on, if any of the above conditions exist. Cleaning the IntelliBeam Light Sensor The light sensor is located on the inside of the vehicle in front of the inside rearview mirror. Disabling and Resetting IntelliBeam at the Rearview Mirror IntelliBeam can be disabled by using the controls on the inside rearview mirror. AUTO 3 (On/Off): Press this button on the inside rearview mirror to disable the system. The IntelliBeam indicator turns off and does not come back on until the IntelliBeam button is pressed again. When IntelliBeam has turned on the high-beams, pull or push the high-beam stalk. This will disable IntelliBeam. The IntelliBeam indicator on the mirror turns off. To turn IntelliBeam back on, press the IntelliBeam button on the mirror. A different sensitivity setting is available for dealer diagnostics. This is done by pushing and holding this button for 20 seconds until the IntelliBeam indicator light flashes three times. If you accidentally activate this, the vehicle' s setting automatically is reset when the ignition is turned off and then on again. Clean the light sensor window, periodically, using glass cleaner on a soft cloth. Gently wipe the sensor window. Do not spray glass cleaner directly on the surface of the sensor window. Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers are turned on and have completed eight wipe cycles within four minutes. When the ignition is turned to LOCK/OFF, the wiper-activated headlamps immediately turn off. The wiper-activated headlamps also turn off if the windshield wipers are turned off. 4-26
