Driving
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.
Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the forward and reverse sensing system may create
false beeps.
The system will sound a tone to warn the driver of obstacles near either
bumper in the following manner:
• The front sensors will sound a high pitched tone which will appear to
come from the dashboard
• The rear sensors will sound a lower pitched tone which will appear to
come from the rear interior of the vehicle
• The sensing system will report the obstacle which is closest to the
front or rear of the vehicle. For example, if an obstacle is 12 inches
(30 cm) from the front of the vehicle and, at the same time, an
obstacle is only 6 inches (15 cm) from the rear of the vehicle, the
lower pitched tone will sound.
The reverse sensing portion of the system will assist the driver in
detecting certain objects while:
• the vehicle is in R (Reverse) and moving toward a stationary object at
a speed of 3 mph (5 km/h) or less.
• the vehicle is in R (Reverse) but not moving, and a moving object is
approaching the front or rear of the vehicle at a speed of 3 mph
(5 km/h) or less.
• the vehicle is in R (Reverse) 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).
