FOB TRAINING: This option allows you to match the
RFA transmitter(s) to your vehicle. You can access this
option by pressing and holding RESET for three
seconds while you are on the blank page at the end of
the OPTIONS menu. The message FOB TRAINING
will be displayed. See ªMatching Transmitter(s) To Your
Vehicleº in the Index for more information.
TIRE TRAINING: The Tire Pressure Monitor (TPM)
operates with battery-powered sensors that are located
inside the valve stems on each tire. Each sensor has a
unique ID code so the vehicle knows the tire location of
the sensor. When the vehicle reaches a speed of greater
than 15 mph (24 km/h), the sensors begin to send the
tire pressure readings to a receiver inside the vehicle.
These readings are displayed when using the GAGES
button on the DIC. If you are unable to display your tire
pressures while the vehicle speed is greater than 15 mph
(24 km/h), you may need to have your sensor ID codes
learned by the vehicle. See your dealer.
