Driving To help avoid personal injury, always use caution when in reverse and when using the system. This system is not designed to prevent contact with small or moving objects. The system is designed to provide a warning to assist the driver in detecting large stationary objects to avoid damaging the vehicle. The system may not detect smaller objects, particularly those close to the ground. The system detects obstacles up to 2 meters (6 ft.) from the rear bumper with a decreased coverage area at the outer corners of the bumper, (refer to the figures for approximate zone coverage areas). As you move closer to the obstacle, the rate of the tone increases. When the obstacle is less than 25.0 cm (10 in.) away, the tone will sound continuously. If the system detects a stationary or receding object further than 25.0 cm (10 in.) from the side of the vehicle, the tone will sound for only three seconds. Once the system detects an object approaching, the tone will sound again. If the Rear Park Assist detects an object and the radio is on, the radio volume will decrease while the tone sounds. When the tone stops sounding, or if the vehicle is shifted out of R (Reverse), the radio will go back to the previously set volume level. The system automatically turns on when the gear selector is placed in R (Reverse) and the ignition is ON. A control in the message center allows the driver to disable the system only when the ignition is ON, and the gear selector is in R (Reverse). Refer to Message center in the Driver Controls chapter for more information. Keep the Rear Park Assist sensors (located on the rear bumper/fascia) free from snow, ice and large accumulations of 231 2003 Aviator f/k/a Navigator LS (231) Owners Guide (post-2002-fmt) USA English (fus)
