REVERSE SENSING SYSTEM (IF EQUIPPED)

The RSS sounds a tone to warn the driver of obstacles near the rear
bumper when R (Reverse) is selected. The RSS will assist the driver in
detecting certain objects while:
• the vehicle is moving toward a stationary object at a speed of 5 km/h

(3 mph) or less.

• the vehicle is in R (Reverse) but not moving backward (the brake

pedal is depressed or the parking brake is applied), and a moving
object is approaching the rear of the vehicle at a speed of 5 km/h (3
mph) or less.

• the vehicle is moving in reverse at a speed of less than 5 km/h (3

mph) and a moving object is approaching the rear of the vehicle at a
speed of less than 5 km/h (3 mph).

The RSS is not effective at speeds greater than 5 km/h (3 mph) and may
not detect certain angular or moving objects.

To help avoid personal injury, please read and understand the
limitations of the reverse sensing system as contained in this

section. Reverse sensing is only an aid for some (generally large and
fixed) objects when moving in reverse on a flat surface at “parking
speeds”. Inclement weather may also affect the function of the RSS;
this may include reduced performance or a false activation.

To help avoid personal injury, always use caution when in R
(Reverse) and when using the RSS.

This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to

assist the driver in detecting large stationary objects to avoid damaging
the vehicle. The system may not detect smaller objects, particularly
those close to the ground.
