Demonstration Mode

DEMONSTRATION MODE

The SmartBeam(R) automatic high beam system has a demonstration mode. This mode allows the function of the automatic high beams accompanied with that of the high beam indicator in the instrument cluster to be demonstrated while the vehicle is stationary and under any ambient lighting conditions. Besides demonstrating the automatic high beam system, this mode will confirm that the system electronics and circuitry are functional. This mode also incorporates a feature that allows a functional test of the imager optics to be performed.

NOTE: The SmartBeam(R) Demonstration Mode will NOT be functional when a diagnostic scan tool is connected to the 16-way Data Link Connector (DLC) beneath the instrument panel on the driver side. Once the demonstration sequence has begun, a detected vehicle speed input of over 8 kilometers-per-hour (5 miles-per-hour) will cause the sequence to be aborted and the automatic high beam system to return to normal operation.

1. Place the headlamp switch in the Automatic (A) position and the beam selector switch in the high beam position.
2. With the ignition switch in the OFF position, depress and hold depressed the power ON/OFF button on the electrochromic inside rear view mirror.
3. With the button still depressed, start the engine by turning the ignition switch to the START position.
4. Continue to hold the button depressed until the Demonstration Mode begins (headlamp high beams and high beam indicator illuminate), at which time the button may be released.
5. The automatic high beam system will complete three cycles of ramping up the headlamp high beams to full brightness, then ramping them down until fully extinguished accompanied by the appropriate indications from the high beam indicator. At the conclusion of this sequence (about 40 seconds), the automatic high beam system will return to normal operation.

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 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(R) 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, Exterior Lighting.

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.
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 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.
