REVERSE SENSING SYSTEM (IF EQUIPPED)

The reverse sensing system sounds a tone to warn the driver of obstacles

near the rear bumper when the R (Reverse) gear is selected.

WARNING: To help avoid personal injury, please read and

understand the limitations of the reverse sensing system as

contained in this section. The park assist is only an aid for some

(generally large and fixed) objects when moving in reverse on a flat

surface at “parking speeds”. Inclement weather may also affect the

function of the RSS; this may include reduced performance or a false

activation.

WARNING: To help avoid personal injury, always use caution

when in R (Reverse) and when using the reverse sensing system.

WARNING: 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 objects to avoid damaging the

vehicle. The system may not detect smaller objects, particularly those

close to the ground.

WARNING: Certain add-on devices such as large trailer hitches,

bike or surfboard racks and any device that may block the

normal detection zone of the reverse sensing system may create false

beeps.

The system will assist the driver in detecting certain objects while the

vehicle moves in reverse at speeds less than 6 mph (10 km/h). The

system is not effective at speeds greater than 6 mph (10 km/h) and may

not detect certain angular or moving objects.

The system detects obstacles within approximately 16 feet (five meters),

at speeds above 2.5 mph (4 km/h) behind the rear bumper with a

decreased coverage area at the outer corners of the bumper. If vehicle

speed is below 2.5 mph (4 km/h), the system detects obstacles within

approximately 9 feet (2.6 meters) behind the rear bumper with a

decreased coverage area at the outer corners of the bumper. As you

move closer to the obstacle, the rate of the tone increases. When the

distance to the obstacle is approximately 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 a 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.

While receiving a warning the radio volume will be reduced to a

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

to the previous value.

The reverse sensing system is automatically enabled 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.

The message center will indicate the system is off and will not allow the

driver to switch the system on to indicate a failure of the reverse sensing

system.

The radar sensor is located behind the rear bumper/fascia. Always

keep the rear bumper/fascia free from snow, ice and large

accumulations of dirt. These elements may cause the system to

operate inaccurately.

If the 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.

FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)

WARNING: For important information regarding safe operation

of this type of vehicle, see Preparing to drive your vehicle in

this chapter.
