What does it mean if Measurement A has reached its maximum or minimum value?The system is designed to work with drawbars that have a license plate to hitch ball center measurement of 9–20 in (23–52 cm) when installed. Do not attempt to use drawbars that have a length outside this range as the system performance degrades and could cause improper system function. Make sure that the measurement being made is the horizontal distance only from the license plate to the hitch ball center. A straight line distance that includes any vertical rise or drop increases the measurement and makes it inaccurate. Inaccurate measurements degrade system performance and could cause improper system function.   See   Applying the Trailer Reversing Aid Sticker.  What does it mean if Measurement B has reached its maximum or minimum value?Make sure that the sticker is properly placed. Stickers placed outside the allowed zone adversely affects the system performance and could cause improper feature function. Make sure that the measurement being made is the horizontal distance only from center of the sticker to the hitch ball center. A straight line distance that includes any vertical rise or drop increases the measurement and causes an inaccurate value to be entered into the system.   See   Applying the Trailer Reversing Aid Sticker.  What does it mean if Measurement C has reached its maximum or minimum value?Make sure you follow the sticker placement instructions. Stickers placed outside the allowed zone adversely affect the system performance and could cause improper feature function. If you have met all the criteria for sticker placement and you see this message, the sticker is either too far below or too close to the camera to properly recognize the sticker. For the system to correctly operate, lower the sticker height if you receive the minimum warning or raise the sticker height if you receive the maximum warning. Only one sticker can be placed on the trailer for correct system function. The previous sticker must be removed or covered so only one sticker is visible to the camera. Measurement B and C must be measured again if a new sticker is placed on the trailer.   See   Applying the Trailer Reversing Aid Sticker.  What does it mean if Measurement D has reached its maximum or minimum value?Make sure that the measurement being made is the horizontal distance only from tailgate to the center of the single axle or the center of all the axles on the trailer. The system does not support trailer lengths outside the range allowed by the information display.   See   Applying the Trailer Reversing Aid Sticker.  Why does the trailer not reverse straight when using a conventional trailer?Factors such as the drawbar connection to the hitch receiver, road camber, road grade and compliance in the trailer suspension can influence how straight the system is able to reverse your trailer when the knob is not turned. You can compensate for the trailer drifting to the right or left by slowly turning the knob until the trailer is following your preferred path and then holding the knob in that position. If you would like to recalibrate the system for straight backing, change the sticker option in the instrument cluster display. Confirm the measurements, and the system prompts you to perform the calibration procedure.Why does the trailer not reverse straight when using a fifth-wheel or gooseneck trailer?Verify the sensor is correctly installed. Other factors such as the hitch connection, road camber, road slope and trailer suspension could influence how straight the system can reverse the trailer when the control knob is not turned. You can compensate for the trailer drifting to the right or left by slowly turning the knob until the trailer is following your desired path and then holding the knob in that position.Why does the system not detect a sensor?There could be an issue with the connection, the wiring harness could be damaged, you could have multiple sensors connected or the sensor could be incorrectly installed. Check that the 12-way connector is fully inserted into the 12-way socket. The red rubber seal is not visible when the connector is fully inserted. Also check that the wiring harness sensor connection is fully inserted at the trailer sensor, and check for damaged wiring between the 12-way connector and the trailer sensor. Also, check that the sensor is installed on a vertical surface with the arrows pointing straight up.What does it mean if the system remains on one message for an extended time during calibration when setting up the system with a conventional trailer?The camera could need to be cleaned, the sticker could be blocked, the drawbar could be outside the allowed range of 4–19 in (10–48 cm) or you could need to move to a different area to change the lighting and background. Verify the sticker is in the proper location.   See   Applying the Trailer Reversing Aid Sticker.  You can move to a different area or change the direction you are driving or setup the system at a different time of day. Some trailers are not compatible with the sticker and camera system.What does it mean if the system pauses during calibration?There could be steering input or trailer movement during the straight drive portion of the calibration process.What does it mean if the system remains on one message for an extended time during calibration when setting up the system with a fifth-wheel or gooseneck trailer?The sensor could be incorrectly installed, the trailer length could be outside the allowed range or the road surface could be too rough or bumpy.What does it mean if the system displays hold steering steady during turn?Part of the calibration process for the sticker setup requires a steady turn. If you are continually moving the steering wheel during the turn, this delays the calibration process. To enable the calibration process, hold the steering wheel at the same position when turning.What does it mean if the system displays that it is not available?There could be a sub-system that the system uses that is not correctly operating or there could be a battery voltage issue. If the system continues to display it is not available, visit your authorized dealer to have your vehicle checked.What does it mean if the system displays that driving is required to initialize steering?The steering system needs to learn internal parameters to fully turn on the feature. Drive your vehicle straight forward above 25 mph (40 km/h) for approximately 5 minutes. This could also occur when your vehicle is new, there is a battery voltage issue or if the steering system has been serviced.What does it mean if the system does not detect a trailer when configured for a fifth-wheel or gooseneck trailer?Verify that the sensor is properly connected.   See   Trailer Sensor Installation.  Repeat calibration on a different route if you have verified sensor installation.What does it mean if the system requires you to pull forward to initialize?This occurs when the vehicle has not moved during the current key cycle after you connect and select the trailer in the instrument cluster display or you operate the system at speeds below 1 mph (1 km/h) for an extended period of time. Drive forward above 2 mph (3 km/h) and the system indicates when it initializes.What does it mean if the trailer is at its maximum angle or the system deactivated by trailer angle when using a conventional trailer?The system uses your measurements to determine sticker position and establish system limits. Accurate sticker placement and trailer measurements provide the best system performance. If you are consistently receiving this warning, it is likely there is an issue with sticker placement or the entered measurements. Make sure that the sticker is placed correctly and the measurements were made correctly.   See   Applying the Trailer Reversing Aid Sticker.  To change the sticker location or change trailer measurements, change the sticker option in the instrument cluster display. If the sticker location needs to be changed, the previous sticker must be removed and a new sticker needs to be placed on the trailer. Only one sticker should be placed on the trailer for proper system function.What does it mean if the trailer is at its maximum angle or the system deactivated by trailer angle when using a fifth-wheel or gooseneck trailer?You are at the maximum controllable trailer angle for the system. Place your vehicle in drive (D) and pull forward to get the truck and trailer back to an in-line position. If this message consistently displays, this could indicate the sensor is incorrectly installed, the trailer needs to be recalibrated or the drawbar or the trailer dimensions are outside of the supported range. The system is designed to work with drawbars that have a license plate to hitch ball center measurement of 9–20 in (23–52 cm) when installed. The system is designed to work with trailers that have a hitch point to center of the axle or axles measurement of 6–33 ft (1.85–10.05 m). Do not attempt to use drawbars or trailers that have a length outside of this range as the system performance degrades and could cause improper system function. Check that the correct trailer is selected in the instrument cluster display. Verify the sensor is installed according to the instructions included in the sensor kit and check that the drawbar and the trailer dimensions are within the allowed range. Then, delete the trailer from the system and repeat the setup process to calibrate the trailer.What does it mean when the system tells you to take control of the steering wheel?The system is no longer steering the vehicle and you must take over steering. There are four reasons the system could display this message. The first reason the system could display this message is that you have touched the steering wheel when the system is steering. The second reason the system could display this message is that you have exceeded the maximum speed for the feature. The third reason the system could display this message is that the trailer is not detected. The final reason the system could display this message is that an internal condition for system operation is not met that requires your vehicle to return to manual control of the steering.What does it mean if the system circles something besides the sticker or cannot find the sticker?The system requires a clear view of the sticker placed on the trailer and accurate measurements to locate the sticker. Remove any items that may be blocking the view of the sticker. Depending on your trailer configuration and any equipment mounted to your trailer, it is possible for the sticker to be blocked from view of the camera as it rotates on the hitch ball but not be blocked during setup. It may be necessary to remove the sticker from its current location if the obstruction cannot be cleared. The sticker location must still meet the requirements noted the setup instructions.   See   Applying the Trailer Reversing Aid Sticker.  Verify the measurements you entered into the system are accurate. To change the sticker location or change trailer measurements, change the sticker option in the instrument cluster display. If the system cannot initially detect the trailer, it could be necessary for you to change the lighting conditions by moving your vehicle and trailer or waiting until the conditions change. Some trailers are not compatible with the sticker and camera system. Only one sticker can be placed on the trailer for correct system function.
