2004 Jeep Grand Cherokee Owner's Manual - Page 83

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 83 NOTE: Since the rain sensor is designed to detect moisture, road spray, smashed bugs, and moisture from passing trucks may occasionally cause the wipers to cycle if the lever is in AUTO. Also, manual intervention may be necessary under certain conditions: Additional wipes may be desired, in foggy/misty mornings, where condensation builds up very slowly on the windshield, or when water accumulated on the roof of the vehicle runs down the windshield, but not over the sensor. Fewer wipes and/or washer fluid may be desired when salty road spray is encountered, where the operator may want to turn the "Auto" feature off and use the "Wash" and/or "Mist" functions. CAUTION! Turn the wiper lever to the OFF position to avoid wiper damage when driving through an automatic car wash. 3 WARNING! Turn the wiper lever to the OFF position when cleaning your windshield to avoid injury.
