Setup
The system is designed to be used with awide variety of trailers. However there aresome trailers that do not have a propersurface and location to mount the sticker.These trailers are not supported. Attemptsto place the sticker on a surface that doesnot meet the sticker placement requirementlisted in Step 3 of the setup instruction orentering inaccurate measurements toproceed through setup can result in impropersystem function.
Accurate measurements are critical to correctsystem function. If you need to checkmeasurements entered or change them youcan access them through the trailer menusin the instrument cluster. Choose the optionto change the sticker from the change trailersettings menu. It is not necessary to removethe sticker if you are just reviewing orchanging measurements.
The following menu warnings or difficultiesmay occur during setup. Tips to resolve themare listed below.
Note:If you still experience issues with thesystem's ability to detect the sticker, see theinformation in the next section regardingsticker lost during system operation.
Measurement A has reached maximum orminimum value:
•The system is designed to work withdrawbars that have a bumper to hitch ballcenter measurement of 4 in (10 cm) to11 in (28 cm) when installed. Do notattempt to use drawbars that have alength outside this range as the systemperformance will be degraded and couldcause improper system function.
•Make sure that the measurement beingmade is the horizontal distance only frombumper and the hitch ball center. Astraight line distance that includes anyvertical rise or drop will increase themeasurement and make it inaccurate.Inaccurate measurements will degradesystem performance and could causeimproper system function. See step 4 ofthe setup instruction to reviewmeasurement instructions.
Measurement B has reached maximum orminimum value:
•Make sure that the sticker placementinstruction in step 3 of the setup hasbeen followed. Stickers placed outsidethe allowed zone will adversely affect thesystem performance and could causeimproper feature function.
•Make sure that the measurement beingmade is the horizontal distance only fromcenter of sticker to the hitch ball center.A straight line distance that includes anyvertical rise or drop will increase themeasurement and cause an inaccuratevalue to be entered into the system. Seestep 4 of the setup for additionalmeasurement instructions.
Measurement C has reached maximum orminimum value:

The system is not available:
•The system relies on many sub-systemsin your vehicle to operate correctly. Ifthose sub-systems are not operatingcorrectly the system may not beavailable.
•Low battery voltage is a condition whichwill prevent the system from operating.Please make sure the battery is correctlycharged if the system is not available.
•You may need to drive your vehiclestraight forward above 25 mph (40 km/h)before the system is available again.
•If the message still displays take yourvehicle to an authorized dealer forservice.
Sticker lost:
•If the system cannot initially find thesticker, it may be necessary for you tochange the lighting conditions by movingthe vehicle and trailer or waiting untilconditions change.
•Check for the following if you receive thelost sticker message while using thesystem.
•Stop your vehicle as soon as themessage displays.
•Make sure the sticker is visible and thepattern is discernable in the rear viewcamera image.
•Clean the sticker and camera to makesure they are unobstructed.
•Clean the lens with a soft, lint-free clothand water.
•Clean the sticker with isopropyl rubbingalcohol sprayed directly onto the sticker,and then wipe clean with a soft cloth.
•Remove any items that may be blockingthe view of the sticker. Depending onyour trailer configuration and anyequipment mounted to your trailer it ispossible for the sticker to be blockedfrom view of the camera as it rotates onthe hitch ball but not be blocked duringsetup. Remove the obstruction ifpossible. It will be necessary to removethe sticker from it’s current location if theobstruction cannot be cleared and placea new sticker that will be visible to thecamera in all positions of the trailerbehind your vehicle.
•Placing the sticker on a surface angledaway from the vehicle reducesperformance. Use a drawbar thatpositions the trailer level to the groundwhen attached to vehicle. This typicallyprovides a level surface to mount thesticker. Place the sticker on a bracket orother object when no level surface isavailable.
•Make sure the entire sticker is on a flatsurface that is completely visible to thecamera. Do not fold the sticker over anedge on the trailer frame. This candegrade performance.
•Shadows on the sticker may effecttracking performance under somelighting conditions. Moving the sticker toanother location within the allowedplacement area may improveperformance. Use the change stickeroption in your Towing menu if you movethe sticker.
