The reverse sensing system is automatically enabled when the gear
selector is placed in R (Reverse) and the ignition is on. A control in the
message center allows the driver to disable the system only when the
ignition is on and the gear selector is in R (Reverse). Refer to Message
center
in the Driver Controls chapter.

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.
