Your vehicle may be equipped with Rainsense windshield wipers. When active, these wipers are able to detect moisture on the windshield and automatically turn on the wipers.

The moisture sensor is located next to the inside rearview mirror and is mounted on the windshield.

To turn on the Rainsense feature, the wipers must be set to one of the five delay settings on the multifunction lever. Each of the five settings adjusts the sensitivity of the rainsensor. For more wipes, select the higher settings; for fewer wipes, select the lower settings located closer to off on the multifunction lever.

The rainsensor will automatically control the frequency of the wipes from off to high speed according to the weather conditions. The wipers can be left in a rainsense mode even when it is not raining.

Notice: If you do not turn off the windshield wipers when driving through an automatic car wash, you could damage the wipers. Always turn off the windshield wipers before entering an automatic car wash.
