1. Select the brake effort level for the trailer.

1. Select the trailer type.

Trailers with single axle:

• The horizontal distance from the tailgate to the center of the trailer axle.

Trailers with dual axles or more:

• The horizontal distance from the tailgate to the center of the axles.

Measurement A has reached maximum or minimum value:

• The system is designed to work with drawbars that have a license plate to hitch ball center measurement of 9 in (23 cm) to 16 in (41 cm) when installed. Do not attempt to use drawbars that have a length outside this range as the system performance will be degraded and could cause improper system function.
• Make sure that the measurement being made is the horizontal distance only from license plate and 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 step 4 of the setup instruction to review measurement instructions.

Measurement B has reached maximum or minimum value:

• Make sure that the sticker placement instruction in step 3 of the setup has been followed. Stickers placed outside the allowed zone will adversely affect the system performance and could cause improper feature function.
• Make sure that the measurement being made is the horizontal distance only from center of 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 step 4 of the setup for additional measurement instructions.

Measurement C has reached maximum or minimum value:

• Make sure you follow the sticker placement instructions in step 3 of the setup. 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. In order for the system to operate correctly, the sticker height must be lowered if you receive the minimum warning or the sticker height must be raised 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.

Measurement D has reached 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. See step 4 of the setup for additional measurement instructions. The system does not support trailer lengths outside the range allowed by the information display.

System is circling something beside the sticker or system cannot find the sticker:

• Make sure the rear camera is clean and the sticker is clearly visible in the camera image. Clean the camera and sticker if necessary.
• The camera system uses the entered measurements to help locate the sticker. Inaccurate sticker measurements degrade the system’s ability to locate the sticker. Verify the measurements you enter into the system are accurate.
• Remove the incorrectly circled label or decal if possible.
• If you cannot resolve the issue, try a new sticker location. The sticker location must still meet the requirements noted in step 3 of the setup instructions. 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.

For best results:

• Use a long, straight, smooth and level road when attempting to calibrate.
• Drive straight forward.
• Drive between 4–24 mph (6–39 km/h).

The system is not available:

• The system relies on many sub-systems in your vehicle to operate correctly. If those sub-systems are not operating correctly, the system may not be available.
• Low battery voltage is a condition which prevents the system from operating. Please make sure the battery is correctly charged if the system is not available.
• You may need to drive your vehicle straight forward above 25 mph (40 km/h) before the system is available again.
• If the message continues to display, see your authorized dealer for service.

Sticker lost:

• If the system cannot initially find the sticker, it may be necessary for you to change the lighting conditions by moving the vehicle and trailer or waiting until conditions change.
• Check for the following if you receive the lost sticker message while using the system.
• Stop your vehicle as soon as the message displays.
• Make sure the sticker is visible and the pattern is discernable in the rear view camera image.
• Clean the sticker and camera to make sure they are unobstructed.
• Clean the lens with a soft, lint-free cloth and water.
• Clean the sticker with isopropyl rubbing alcohol sprayed directly onto the sticker, and then wipe clean with a soft cloth.
• 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. Remove the obstruction if possible. It may be necessary to remove the sticker from its current location if the obstruction cannot be cleared. Place a new sticker that is visible to the camera in all positions of the trailer behind your vehicle.
• Placing the sticker on a surface angled away from the vehicle reduces performance. Use a drawbar that positions the trailer level to the ground when attached to the vehicle. This typically provides a level surface to mount the sticker. Place the sticker on a bracket or other object when no level surface is available.
• Make sure the entire sticker is on a flat surface that is completely visible to the camera. Do not fold the sticker over an edge on the trailer frame. This can degrade performance.
• Shadows on the sticker may effect tracking performance under some lighting conditions. Moving the sticker to another location within the allowed placement area may improve performance. Use the change sticker option in the information display menu if you move the sticker.
• You can change your sticker location by going into the information display menu, selecting trailer options, selecting change trailer settings and then selecting the change sticker option. The previous sticker must be removed. ONLY ONE STICKER SHOULD BE PLACED ON THE TRAILER FOR CORRECT SYSTEM FUNCTION.
• The camera system uses the entered measurements to help locate the sticker. Inaccurate measurements reduce the system’s ability to locate the sticker. Check the measurements entered into the system are correct. Refer to step 4 of setup for instructions on measurements.
• You can change your measurement by going into the information display menu, selecting trailer options, selecting change trailer setting and then selecting the change sticker option. Disregard the prompt to remove this sticker and continue to the next step if you only plan to update the measurements for the current sticker location.

System does not reverse straight:

• 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 desired path and then holding the knob in that position. If you would like to recalibrate the system for straight backing, you can do so with the following procedure.
• Go into the information display menu, select trailer options, select change trailer setting and then select the change sticker option. Your saved measurements display. Do not change them but continue to confirm measurements. Once you confirm the measurements, the system then prompts you to perform the calibration procedure.

System consistently shows :

• 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 based on step 3 and the measurements were made correctly according to step 4. The troubleshooting guide for trailer measurements can also be reviewed for help in making measurements.
• To change sticker location or change trailer measurements, go into the information display menu, select trailer options, select change trailer setting and then select the change sticker option.
• 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.
• Disregard the prompt to remove this sticker and continue to the next step if you only plan to update the measurements for the current sticker location.

System consistently shows :

• The system displays this warning when it can no longer steer the vehicle and you must take over steering. There are four reasons why this warning displays and additional information regarding the reason for the warning is available on the center display.
• The steering wheel is touched while under system control. Avoid touching the wheel during system operation.
• The maximum speed for feature operation is exceeded. System performance is optimized at slower speeds. Reverse slowly.
• The sticker was lost by the camera system. Once your vehicle is stopped, additional warnings indicate the sticker was lost. Refer to sticker lost troubleshooting tips.
• An internal condition for system operation was not met which requires your vehicle return to manual control of the steering.
