Start the engine and leave the transmission gear selector lever in the PARK position. Press and hold the RESET button on the steering wheel (for approximately ten seconds) until the current variance zone number is displayed.

To change the zone, press and release the STEP button to increase the variance one step. Repeat as necessary until the desired variance is achieved.

NOTE: The factory default zone is 8. During programming, the zone value will wrap around from zone 15 to zone 1.
