either too far below or too close to thecamera to properly recognize the sticker.In order for the system to operatecorrectly the sticker height must belowered if you receive the minimumwarning or the sticker height must beraised if you receive the maximumwarning.
•Only one sticker can be placed on thetrailer for correct system function. Theprevious sticker must be removed orcovered so only one sticker is visible tothe camera.
•Measurement B and C must be measuredagain if a new sticker is placed on thetrailer.
Measurement D has reached maximum orminimum value:
•Make sure that the measurement beingmade is the horizontal distance only fromthe bumper to the center of the singleaxle or the center of all the axles on thetrailer. See step 4 of the setup foradditional measurement instructions. TheTBA system does not support trailerlengths outside the range allowed by theinformation display.
System is circling something beside thesticker or system cannot find the sticker:
•Make sure the rear camera is clean andthe sticker is clearly visible in the cameraimage. Clean the camera and sticker ifnecessary.
•The camera system uses the enteredmeasurements to help locate the sticker.Inaccurate sticker measurements willdegrade the system’s ability to locate thesticker. Verify the measurements enteredinto the system are accurate.
•Remove the incorrectly circled label ordecal if possible.
•If you cannot resolve the issue a newsticker location should be tried. Thesticker location must still meet therequirements noted in step 3 of the setupinstructions. Only one sticker can beplaced on the trailer for correct systemfunction. The previous sticker must beremoved or covered so only one stickeris visible to the camera.
Calibration
The system monitors various vehicleparameters to ensure your vehicle is beingdriven straight and the trailer straight behindyour vehicle. Any steering input or trailermovement will pause the calibration.
For best results:

Before Towing a Trailer
Practice turning, stopping and backing up toget the feel of your vehicle-trailercombination before starting on a trip. Whenturning, make wider turns so the trailerwheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control when carryingheavy loads or in hilly terrain. The speedcontrol may turn off automatically whenyou are towing on long, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission has a Grade Assistor Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•If your vehicle has AdvanceTrac withRSC, this system may turn on duringtypical cornering maneuvers with aheavily loaded trailer. This is normal.Turning the corner at a slower speedwhile towing may reduce this tendency.
•If your vehicle has Adaptive suspension,you can select NORMAL or SPORT drivecontrol modes for better experiencewhen towing a trailer. See InformationDisplays (page 119).
•If you are towing a trailer frequently inhot weather, hilly conditions, at the grosscombined weight rating (or anycombination of these factors), considerrefilling your rear axle with synthetic gearlubricant (if the axle is not already filledwith it). See Capacities andSpecifications (page 422).
•Allow more distance for stopping with atrailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4.Place wheel chocks in the front and backof the trailer wheels.
Note:Chocks are not included with yourvehicle.
