● The system is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the ve-
hicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or
on the ground.
● If your vehicle sustains damage to the
rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate measure-
ment of obstacles or false alarms.
The Rear Sonar System (RSS) sounds a tone to
warn the driver of obstacles near the rear bumper
when the shift selector is in R (Reverse). The
system may not detectobjects at speeds above 3
mph (5 km/h) and may not detect certain angular
or moving objects.
The RSS detects obstacles up to 6 feet (1.8 m)
from the rear bumper with a decreased coverage
area at the outer corners of the bumper, (refer to
the illustration 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 station-
ary 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 sys-
tem detects an object approaching, the tone will
sound again.
The RSS automatically turns on when the shift
selector lever is placed in R (Reverse) and the
ignition is ON. The RSS OFF switch on the
instrument panel allows thedriver to turn the RSS
on and off. To turn the RSS off, the ignition must
be ON, and the shift selector lever in R (Reverse).
An indicator light on the switch 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.
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.
WARNING
● Always look around before proceeding.
The FSS is not a substitute for proper
driving procedures.
● Read and understand the limitations of
the front sonar system as contained in
this section. Inclement weather may af-
fect the function of the FSS, this may
include reduced performance or a false
activation.
● This system is not designed to prevent
contact with small or moving objects.
