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.

While receiving a warning, on some radios, the volume will be reduced to

a predetermined level. After the warning goes away, the radio will return

to the previous value.

The RSS automatically turns on when the gearshift lever is placed in R

(Reverse) and the ignition is on. A control in the message center allows

the driver to disable the system, refer to Message center in the

Instrument Cluster chapter for more information.

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.

If your vehicle sustains damage to the rear bumper/fascia, leaving

it misaligned or bent, the sensing zone may be altered causing

inaccurate measurement of obstacles or false alarms.
