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. 296 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus)
