The system detects obstacles within approximately 16 feet (five meters),
at speeds above 2 mph [3 km/h]) behind the rear bumper with a
decreased coverage area at the outer corners of the bumper. If vehicle
speed is below 2 mph (3 km/h), the system detects obstacles within
approximately 10 feet (three meters) behind the rear bumper with a
decreased coverage area at the outer corners of the bumper. In the
figure, the smaller objects behind the vehicle represent the near-vehicle
and bumper corner coverage area of the park aid system and the large
object represents the extended coverage area. 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.
The extended rear park aid is
automatically enabled when the gear
selector is placed in R (Reverse)
and the ignition is ON. A park aid
control allows the driver to disable
the extended rear park aid only
when the ignition is ON, and the
gear selector is in R (Reverse).
The OFF indicator remains
illuminated when the system is
disabled. The system defaults to ON
every time the ignition is turned on. Press the control to disable or
enable the system.
