The rear parking aid sensors automatically turn on when you shift into reverse (R).
As your 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 an object farther than 12 in (30 cm) from the corners of the bumper, the tone sounds for only three seconds. If the system detects an approaching object the warning sounds again.

Coverage area of up to 6 ft (1.8 m) from the rear bumper. There is decreased coverage area at the outer corners of the bumper.
The system detects certain objects while the transmission is in reverse (R) :
  • Your vehicle is moving toward a stationary object at a speed of 3 mph (5 km/h) or less.
  • Your vehicle is not moving, but a moving object is approaching the rear of your vehicle at a speed of 3 mph (5 km/h) or less.
  • Your vehicle is moving at a speed of less than 3 mph (5 km/h) and a moving object is approaching the rear of your vehicle at a speed of less than 3 mph (5 km/h).
