The RSS detects obstacles up to
6 feet (2 meters) 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 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) 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.
The RSS may have reduced
performance or an increased chance
of false detection if the tailgate is
not locked and in the upright position. If the tailgate is down, the RSS
tone may be heard intermittently or continuously. The tone may also be
heard if items in the truck bed protrude rearward outside the bed.
The RSS automatically turns on
when the gearshift lever is placed in
R (Reverse) and the ignition is on.
An RSS control allows the driver to
turn the RSS on and off. To turn the
RSS off, the ignition must be on,
and the gear selector in R
(Reverse). An indicator light on the
control will illuminate when the system is turned off. If the indicator
light illuminates when the RSS is not turned off, it may indicate a failure
in the RSS. The RSS will remain off until either the RSS control is
pushed again or the ignition switch is recycled.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
