Important Information
Before using the backup sensors, make sure you read and understand the operation and limitations
of the system as discussed throughout this manual.
• The backup sensors are designed to provide an 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 objects depending on their size, shape, and location.
• Even with the backup sensors, the driver is still responsible for making sure the path is
clear when driving 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.
The sensors operate by emitting ultrasonic waves. They calculate the distance between the rear bumper and
an obstacle by measuring the time the ultrasonic waves take to reach the sensor after being reflected by an
obstacle.
