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 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 RSS system may create false beeps.
The system will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 6 mph (10 km/h).
The system is not effective at speeds greater than 6 mph (10 km/h) and
may not detect certain angular or moving objects.
The system detects obstacles up to a maximum range of 20 feet
(six meters at speeds above 2 mph [3 km/h]) or 10 feet (3 meters at
speeds below 2 mph [3 km/h) behind the rear bumper with a decreased
coverage area at the outer corners of the bumper, (refer to the figures
for approximate zone coverage areas). As you move closer to the
obstacle, the rate of the tone increases. When the distance to the
obstacle is less than 18 inches (45.0 cm), the tone will sound
continuously. If the system detects an object that is approaching the
vehicle at such as rate that rapid braking is required, a very high rate
tone will sound. If this tone is heard while reversing, the driver is
advised to slow down immediately until the tone either changes to a
slower rate or stops.
Whenever a warning is received, the radio volume will be lowered to a
volume that allows the tones to be heard. The radio volume will return to
the previous level after the warning goes away.
The extended rear park assist is automatically enabled when the gear
selector is placed in R (Reverse) and the ignition is ON. A park assist
