Rain/Light Sensor

This rain/light sensor (RLS) detects rain, snow, or other precipitation on the windshield and can determine the amount of ambient light.

If the windshield wipers are set to intermittent operation, they automatically start clearing the windshield when the RLS detects precipitation. For additional windshield wiper and headlight information, see Steering Wheel Pods.

If the headlight switch is set to the automatic or 'A' position, the low beam headlights and vehicle exterior lights turn on when the RLS registers a low level of ambient light. This could happen due to sunset, fog, smoke, or any other event that decreases light levels.
