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.
