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. 242 2007 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
