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 12 inches
(30 centimeters) away, the warning sounds continuously. If a stationary
or receding object is detected farther than 12 inches (30 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.
A
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).
The system can be turned off using the information display control.
Refer to the Information Display chapter. If a fault is present in the
system, a warning message appears in the information display and does
not allow the driver to switch the faulted system on.
