If the vehicle is equipped with a rain/light sensor (see Fig.) and the wiper switch is in set to an intermittent setting, the wipers will start when the sensor detects rain or snow.

If the vehicle is moving faster than 40 mph (64 km/h) the wiper speed will automatically increase and decrease, dependent upon how much moisture builds up on the windshield between wipes.

If the wiper switch is set to a continuous speed (low or high), input from the rain/light sensor is ignored.

The behavior of the wipers based on the rain/light sensor input is independent of the headlamp switch position.

Note: If a rain/light sensor is installed in the MPC2 bracket, the lens area of the camera will appear shiny when viewed through the windshield because of the silicone gel between the lens and the windshield. If no rain/light sensor is installed, the plastic plug placed in the bracket will appear as a flat black circle.

A vehicle equipped with automatic headlights and an A option on the headlight switch (see Fig.) should be equipped with a rain/light sensor.
