Note:You can purchase additional stickersthrough your authorized dealer.
CALIBRATING THE SYSTEM
Calibrating the system requires drivingforward and turning left or right. Follow theinstructions on the touchscreen tocomplete the calibration process.
Note:To calibrate the system, you need anarea where you can safely drive forward andturn left or right. An open parking lot is anideal place to perform the calibration.
Note:Keep the steering wheel straightwhen instructed to by the touchscreen. Ifthe steering wheel is in a turned positionduring this instruction, the calibrationpauses.
Note:During calibration, the systemdetermines the trailer length. The systemsupports trailer lengths of 6–33 ft(1.85–10.05 m) distance from the hitchpoint to the center of the axle or axles. Thesystem is designed to work with drawbarsthat have a license plate to hitch ball centermeasurement of 9–18 in (23–46 cm) wheninstalled. Do not attempt to use drawbarsor trailers that have a length outside of thisrange as the system performance degradesand could cause improper system function.
Note:The touchscreen shows if you aregoing too slow or fast. Calibration pauses ifthe speed is outside the required range of2–9 mph (4–15 km/h).

Note:You need to complete at least a 90°turn, and longer trailers could require a 180°turn. Camera trailer tracking requires thesystem to locate the hitch ball as well asdetermine the trailer length. Some trailerscould require you to drive straight then turnmultiple times before calibration completes.The touchscreen provides instructions andnotifies you when calibration completes.
Note:For best results, do not calibrate thesystem at night when calibrating.
