Perimeter Lighting Perimeter lighting provides a period of exterior vehicle lighting. Perimeter lighting activates when the key is removed from the ignition or the vehicle is unlocked using the remote keyless entry transmitter. The amount of time the exterior lamps will remain on can be programmed using the Driver Information Center (DIC). See "EXIT LIGHT DELAY" under DIC Vehicle Personalization on page 3-71 for additional information. Battery Run-Down Protection This helps prevent the vehicle's battery from draining in case the interior courtesy lamps, reading lamps, trunk lamp, underhood lamp, glove box lamps, or sun visor vanity lamps, if equipped, are accidently left on. If any of these lamps are left on while the ignition is off, they will automatically turn off after 10 minutes. The lamps will not come back on again until one of the following occurs: Overhead Console Reading Lamps Your vehicle may have reading lamps located on the overhead console. Press the lens to turn them on and off. • The ignition is turned on. • The interior lamps control is turned off, then to door or on. Ultrasonic Rear Parking Assist (URPA) Your vehicle may be equipped with Ultrasonic Rear Parking Assist (URPA). URPA is designed to help you park while in REVERSE (R) and operates only at speeds less than 3 mph (5 km/h). URPA can help you avoid colliding with objects such as parked vehicles. The system can detect objects 5 feet (1.5 m) behind your vehicle and tell you how close those objects are to your rear bumper. Rear Assist Handle Reading Lamps Your vehicle may have reading lamps located near the rear assist handles. Press the lens to turn them on and off. 3-18
