NOTICE Control for setting wiper delay Turn the rain sensor off before washing the car in an automatic carwash, to avoid damaging the windshield wipers.

The system varies the frequency of wiping between single sweeps and continuous wiping, depending on the amount of precipitation. Activate the rain sensor by lifting the stalk switch to the AUTO position. The wipers make one sweep for reference to see how much water is on the windshield. In the future, the sensor compares the amount of water on the windshield with this reference value.
