Driving The system detects obstacles within approximately 16 feet (five meters), at speeds above 2 mph [3 km/h]) behind the rear bumper with a decreased coverage area at the outer corners of the bumper. If vehicle speed is below 2 mph (3 km/h), the system detects obstacles within approximately 10 feet (three meters) behind the rear bumper with a decreased coverage area at the outer corners of the bumper. In the figure, the smaller objects behind the vehicle represent the near-vehicle and bumper corner coverage area of the park aid system and the large object represents the extended coverage area. As you move closer to the obstacle, the rate of the tone increases. When the distance to the obstacle is less than 18 inches (45.0 cm), the tone will sound continuously. If the system detects an object that is approaching the vehicle at such as rate that rapid braking is required, a very high rate tone will sound. If this tone is heard while reversing, the driver is advised to slow down immediately until the tone either changes to a slower rate or stops. The extended rear park aid is automatically enabled when the gear selector is placed in R (Reverse) and the ignition is ON. A park aid control allows the driver to disable the extended rear park aid only when the ignition is ON, and the gear selector is in R (Reverse). The OFF indicator remains illuminated when the system is disabled. The system defaults to ON every time the ignition is turned on. Press the control to disable or enable the system. 249 2005 Town Car (tow) Owners Guide (post-2002-fmt) USA_English (fus)
