Using the Front and Rear Sensing System
Rear Sensing System
The rear sensors are only active when the transmission is in R (Reverse).
As the vehicle moves closer to the obstacle, the rate of the audible
warning increases. When the obstacle is fewer than 10 inches (25
centimeters) away, the warning sounds continuously. If a stationary or
receding object is detected farther than 10 inches (25 centimeters) from
the side of the vehicle, the tone sounds for only three seconds. Once the
system detects an object approaching, the warning sounds again.

(2 meters) from the rear bumper
(with a decreased coverage area at
the outer corners of the bumper).
The system detects certain objects while the transmission is in R
(Reverse):
• and moving toward a stationary object at a speed of 3 mph (5 km/h)
or less.
• but not moving, and a moving object is approaching the rear of the
vehicle at a speed of 3 mph (5 km/h) or less.
• and moving at a speed of less than 3 mph (5 km/h) and a moving
object is approaching the rear of the vehicle at a speed of less than
3 mph (5 km/h).
Front Sensing System
The front sensors are active when the gearshift is in any position other
than P (Park) or N (Neutral) and the vehicle speed is below 8 mph
(13 km/h).
