Important Information
Before using the backup sensors, make sure you read and understand the operation and limitations
of the system as discussed below and elsewhere in this manual.
• The backup sensors are designed to provide and audible sound when they detect large
stationary objects while the vehicle is moving in reverse at low speed. However, the system
may not detect all possible objects depending on their size, shape, or location.
• Even with the backup sensors, the driver is still responsible for making sure the path is clear
when operating the vehicle in reverse.

How the Backup Sensors Work
Backup Sensors
The sensors are ready for operation when the shift
lever is moved to the reverse position.
Operation of the sensors is dependent upon the
ultrasonic waves they emit. They calculate the
distance between the sensor and a rear obstacle by
measuring the time until the ultrasonic waves reach
the sensor after being reflected by the obstacle.
