Imager Optics Test

If the green Light Emitting Diode (LED) located on the electrochromic inside rear view mirror to the right of the power on/off button (w/o hands-free communication option) or to the left of the "Auto" button (w/hands-free communication option) does not flash on and off several times when the ignition switch is turned to the On position, but the automatic high beam system is not operating as it should, the SmartBeam imager optics may be dirty or obstructed. The optics of the imager may be tested while the automatic high beam system is in the Demonstration Mode. This test will confirm that the imager can see ambient light through the imager lens and the windshield. If the LED does flash when the ignition switch is turned to the On position, refer to testing.

1. Begin by initiating the automatic high beam Demonstration Mode.
2. Observe the green LED located on the electrochromic inside rear view mirror to the right of the power on/off button (w/o hands-free communication option) or to the left of the "Auto" button (w/hands-free communication option).
3. Obstruct the view of the imager by placing a hand or another suitable obstruction between the imager lens and the windshield, or over the windshield glass in front of the imager. The LED should extinguish each time the optics are obstructed, then illuminate again each time the obstruction is removed.
4. Failure of the LED to respond to these inputs indicates that the imager optics are obstructed.

CAUTION: Do not spray glass cleaners directly onto the imager lens. Damage to the imager optics and electronics may result.

5. Clean the imager lens and the windshield glass and/or remove any obstructions from the windshield in front of the imager. To clean the imager lens, spray a small amount of glass cleaner onto a soft cloth and gently wipe the lens clean.
6. Repeat the test to confirm proper automatic high beam imager operation.
