STEERING
Electric Power Steering
WARNING: The electric powersteering system has diagnostic checks thatcontinuously monitor the system. If a faultis detected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch theignition off. After at least 10 seconds,switch the ignition on and watch theinformation display for a steering systemwarning message. If a steering systemwarning message returns, have the systemchecked by an authorized dealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

The Pre-Collision Assist system is temporarily disabled. Pre-CollisionAssist should automatically reactivate a short time after the weatherconditions improve.
Swirling water, or snow or ice on the surface of the road may interferewith the radar signals.
Contact an authorized dealer to have the radar checked for propercoverage and operation.Radar is out of alignment due to a front end impact.
Clean the outside of the windshield in front of the camera.The windshield in front of the camera is dirty or obstructed in someway.
Wait a short time. It may take several minutes for the camera to detectthat there is no obstruction.The windshield in front of the camera is clean but the message remainsin the display.
Note:Proper system operation requires aclear view of the road by the camera. Haveany windshield damage in the area of thecamera's field of view repaired.
Note:If something hits the front end of yourvehicle or damage occurs, the radar sensingzone may change. This could cause missedor false vehicle detections. Contact anauthorized dealer to have the radar checkedfor proper coverage and operation.
Note:If your vehicle detects excessive heatat the camera or a potential misalignmentcondition, a message may display in theinformation display indicating temporarysensor unavailability. When operationalconditions are correct, the messagedeactivates. For example, when the ambienttemperature around the sensor decreasesor the sensor automatically recalibratessuccessfully.

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:
•Use a long, straight, smooth and levelroad when attempting to calibrate.
•Drive straight forward.
•Drive between 4 mph (6 km/h) and24 mph (39 km/h).
