Backup Sensor System If equipped Your vehicle has a backup sensor system. This system lets you know the approximate distance between your vehicle and most obstacles with an audible signal while you are parking. The sensors are installed in the rear bumper. There are two corner sensors, one on each side, and two center sensors in the middle of the rear bumper. Operation The system is activated and a beeper sounds once when you put the transmission into reverse. As your vehicle is nearing an obstacle, the system makes the audible signal to let you know the approximate distance between your vehicle and the obstacle. If there are more than two obstacles around the rear bumper, the system informs you of the nearest obstacle's distance from the rear bumper. All obstacles may not always be sensed. Even with this system, you should look for obstacles near your vehicle to make sure it is safe to park. The beeping changes according to the distance between the rear bumper and an obstacle: Signal Distance from the Bumper Corner Center Sensors Sensors Within Within 24 in 59 in (60 cm) (150 cm) Within Within 16 in 39 in (40 cm) (100 cm) Within Within 10 in 20 in (25 cm) (50 cm) Features Short beeps Very short beeps Continuous beeps CONTINUED 377
