Rear Sensing System
The rear sensors are only active when the
transmission is in reverse (R). As the vehicle
moves closer to the obstacle, the rate of the
audible warning increases. When the
obstacle is less than 12 in (30 cm) away, the
warning sounds continuously. If the system
detects a stationary or receding object
farther than 12 in (30 cm) from the side of the
vehicle, the tone sounds for only three
seconds. Once the system detects an object
approaching, the warning sounds again.
