• Your vehicle is loaded such that the front end of the vehicle points upward, causing the IntelliBeam sensor to aim high and not detect headlamps and taillamps. • You are driving on winding or hilly roads. 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. A different sensitivity setting is available for dealer/retailer 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. 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.
