You can compensate for thetrailer drifting to the right or left byslowly turning the knob until the traileris following your desired path andholding the knob in that position.Check that the correct trailer isselected in the touchscreen. Verify thesticker is correctly applied and checkthat the drawbar and the trailerdimensions are within the allowedrange. If the trailer consistently doesnot reverse straight, delete the trailerfrom the system and repeat the setupprocess to calibrate the trailer.
What does it mean if the systemremains on one message for anextended time during calibration?
The camera could need to be cleaned,the sticker could be blocked, thedrawbar could be outside the allowedrange of 9–18 in (23–46 cm) or youcould need to move to a different areato change the lighting and background.Verify the sticker is in the properlocation. See Applying the TrailerReversing Aid Sticker (page 371).You can move to a different area orchange the direction you are driving orset up the system at a different timeof day. Some trailers are notcompatible with the sticker andcamera system.
What does it mean if the system pausesduring calibration?
There could be steering input or trailermovement during the straight driveportion of the calibration process.
What does it mean if the systemdisplays hold steering steady duringturn?
Part of the calibration process for thesticker setup requires a steady turn. Ifyou are continually moving thesteering wheel during the turn, thisdelays the calibration process. Toenable the calibration process, holdthe steering wheel at the sameposition when turning.

What does it mean if the trailer is at itsmaximum angle or the systemdeactivated by trailer angle?
You are at the maximum controllabletrailer angle for the system. Place yourvehicle in drive (D) and pull forward toget the truck and trailer back to anin-line position. If this messageconsistently displays, this couldindicate the sticker is incorrectlyapplied, the trailer needs to berecalibrated or the drawbar or thetrailer dimensions are outside of thesupported range. The system isdesigned to work with drawbars thathave a license plate to hitch ball centermeasurement of 9–18 in (23–46 cm)when installed. The system is designedto work with trailers that have a hitchpoint to center of the axle or axlesmeasurement of 6–33 ft(1.85–10.05 m). Do not attempt to usedrawbars or trailers that have a lengthoutside of this range as the systemperformance degrades and couldcause improper system function.Check that the correct trailer isselected on the touchscreen. Verifythe sticker is correctly applied andcheck that the drawbar and the trailerdimensions are within the allowedrange. Then, delete the trailer from thesystem and repeat the setup processto calibrate the trailer.
What does it mean when the systemtells you to take control of the steeringwheel?
The system is no longer steering thevehicle and you must take oversteering. There are four reasons thesystem could display this message.The first reason the system coulddisplay this message is that you havetouched the steering wheel when thesystem is steering. The second reasonthe system could display this messageis that you have exceeded themaximum speed for the feature. Thethird reason the system could displaythis message is that the trailer is notdetected. The final reason the systemcould display this message is that aninternal condition for system operationis not met that requires your vehicle toreturn to manual control of thesteering.
What does it mean if the system doesnot detect a trailer?
The system requires a clear view of thesticker placed on the trailer. You mustkeep the camera lens and sticker cleanfor the system to correctly operate. Ifthe system cannot initially detect thetrailer, it could be necessary for you tochange the lighting conditions bymoving your vehicle and trailer orwaiting until the conditions change.See Applying the Trailer ReversingAid Sticker (page 371). Some trailersare not compatible with the stickerand camera system.
Note:The system is designed to be usedwith the same trailer connection every timeyou choose the trailer from the touchscreen.When using a different drawbar or adifferent pinhole on drawbars with morethan one, connecting the drawbar to yourvehicle affects the trailer position and youmay need to repeat the trailer setup andcalibration process.

Use the sticker placement card and a tapemeasure to determine the appropriate areato place the sticker. The sticker is in theback cover pocket of your quick start guide.Make sure the entire sticker is within thegreen zone between the two arcs ordistance markers on the diagram, and isalso visible in the rear view camera display.
Once you have found the correct location,place the sticker.
Note:Make sure nothing can obstruct therear view camera's view of the sticker suchas a jack handle or wiring.
Note:Position the sticker on a flat, dry andclean horizontal surface. For best results,apply the sticker when temperatures areabove 32°F (0°C).
Note:Do not move stickers after placingthem. Do not re-use any stickers if removed.
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.
