Controls and features The reverse sensing system detects obstacles within approximately 1.8 meters (5.9 ft.) of 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 distance to the obstacle is less than 25.0 cm (10 in.), 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. The reverse sensing system is OFF automatically enabled when the gear selector is placed in R (Reverse) and the ignition is ON. A reverse sensing control allows the driver to disable the reverse sensing system 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 reverse gear is selected. Press the control to disable or enable the system. The indicator will remain illuminated to indicate a failure of the reverse sensing system. The reverse sensing system may have reduced performance or an increased chance of false detection if the tailgate is not locked in the vertical position. When the tailgate is down, the driver may experience a continuous or intermittent tone. This also applies if items being hauled in the box do not fit entirely inside and protrude rearward. 28
