Check

Turn the ignition ON, engine OFF.

Set the parking brake.

Place the gearshift in REVERSE (R) for rear parking aid sensors.

Place the gearshift in DRIVE (D) for front parking aid sensors.

Using a diagnostic scan tool, monitor the parking aid sensor distance Parameter Identifications (PIDs) to verify no objects are detected.

If the audible warning is heard or if the Parameter Identifications (PIDs) indicate an object is detected, check to make sure the bumper is correctly installed and is not tilted downward so the sensor is pointing at the ground. Refer to Diagnosis and Testing.

Wheel to Hub Runout Minimization. General Procedures

Check

NOTE: Wheel-to-hub optimization is important. Clearance between the wheel and hub can be used to offset or neutralize the Road Force® or run-out of the wheel and tire assembly. For every 0.001 inch of wheel-to-hub clearance, the Road Force® can be affected between 1 and 3 pounds depending on the tire stiffness.

NOTE: The example below illustrates how the clearance between the wheel and the hub can be used to offset the high spot of radial run-out or Road Force®. Following the procedure will make sure of the best optimization.

Position the wheel and tire assembly on the vehicle so that the high spot location of radial run-out or Road Force® is at the 6 o'clock position and
