Adjustment [02/2024 - ]: Procedure

  1. INSPECT TIRE 

    Refer to INSPECTION [02/2024 - ]

  2. MEASURE VEHICLE HEIGHT 
    NOTE:
    • Be sure to perform measurement on a level surface.
    • Inspect while the vehicle is unloaded.
    • The standard value shown here is a value that is used for performing a wheel alignment and does not indicate the height of an actual vehicle.
