To help avoid personal injury, always use caution when in
reverse and when using the system.
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.
The system detects obstacles up to
2 meters (6 ft.) from 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 obstacle is less than 25.0 cm (10
in.) away, the tone will sound
continuously. If the system detects a
stationary or receding object further
than 25.0 cm (10 in.) from the side
of the vehicle, the tone will sound
for only three seconds. Once the
system detects an object
approaching, the tone will sound
again. If the Rear Park Assist
detects an object and the radio is
on, the radio volume will decrease
while the tone sounds. When the
tone stops sounding, or if the vehicle is shifted out of R (Reverse), the
radio will go back to the previously set volume level.
The system automatically turns on when the gear selector is placed in R
(Reverse) and the ignition is ON. A control in the message center allows
the driver to disable the system only when the ignition is ON, and the
gear selector is in R (Reverse). Refer to Message center in the Driver
Controls chapter for more information.
Keep the Rear Park Assist sensors (located on the rear
bumper/fascia) free from snow, ice and large accumulations of
