Note:

For vehicles equipped with VSC, if the wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:


  1. Disconnect the cable from the negative (-) battery terminal for more than 2 seconds.

  2. Reconnect the cable from the negative (-) battery terminal.

    MEASURE VEHICLE HEIGHT

    Note:

    • Before inspecting the wheel alignment, adjust the vehicle height to the specified value.

    • Be sure to perform measurement on a level surface.

    • If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.


    1. Bounce the vehicle up and down at the corners to stabilize the suspension.

    2. Measure the vehicle height.

      Measurement points
      A
      Ground clearance of front wheel center
      B
      Ground clearance of No. 1 lower suspension arm bushing set bolt center
      C
      Ground clearance of rear wheel center
      D
      Ground clearance of rear trailing arm bushing set bolt center
      Vehicle Height (Unloaded Vehicle)
      Front A - B Rear C - D
      93 mm (3.66 in.) -40 mm (1.57 in.)

    INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION


    1. Install the camber-caster-kingpin gauge or place the front wheels on the center of the wheel alignment tester.

    2. Inspect the camber, caster and steering axis inclination.

      Camber (Unloaded Vehicle)
      Camber Inclination Right-left Difference

      -0°10' +/- 45'

      (-0.17° +/- 0.75°)

      Caster (Unloaded Vehicle)
      Caster Inclination Right-left Difference

      5°40' +/- 45'

      (5.67° +/- 0.75°)

    ADJUST CAMBER

    Note:

    Inspect toe-in after the camber has been adjusted.


    1. Remove the front wheel.

    2. A01CE5P

      Remove the bolt and separate the front speed sensor and front flexible hose from the front shock absorber.

    3. A01CGFC

      Loosen the 2 nuts.

      Note:

      Keep the bolts inserted.

    4. Clean the installation surfaces of the front shock absorber and the steering knuckle.

    5. Temporarily install the 2 nuts. (Step A)

    6. A01CCZ6

      Fully push or pull the front axle hub in the direction of the required adjustment. (Step B)

    7. A01CGFC

      Tighten the nuts.

      240 N*m 2447 kgf*cm 177 ft.*lbf
      Note:

      Keep the bolts from rotating when tightening the nuts.

    8. A01CE5P

      Install the front speed sensor and front flexible hose to the front shock absorber with the bolt.

      19 N*m 194 kgf*cm 14 ft.*lbf
      Note:

      Do not twist the front speed sensor when installing it.

    9. Install the front wheel.

    10. A01CBIGE40
      A01CBIGE39
      A01CC8KE01

      Check the camber.

      Camber (Unloaded Vehicle)
      Camber Inclination Right-left Difference

      -0°10' +/- 45'

      (-0.17° +/- 0.75°)

      		 45' (0.75°) or less

      If the measured value is not within the specification, calculate the required adjustment amount using the formula below.

      Camber adjustment amount = center of the specified range - measured value

      Check the combination of the installed bolts. Select appropriate bolts from the tables below to adjust the camber to the specified values.

      Tip:

      Try to adjust the camber to the center of the specified values.

      Move the axle hub toward (+) in step B Move the axle hub toward (-) in step B
      Refer to table (1) (Move the axle hub toward the positive side) Refer to table (2) (Move the axle hub toward the negative side)

      The body and suspension may be damaged if the camber is not correctly adjusted according to the tables above.

      Note:

      Replace the nut with a new one when replacing the bolt.

    11. Repeat the steps mentioned above. In Step A, replace 1 or 2 selected bolts.

      Tip:

      Replace one bolt at a time when replacing both bolts.

    INSPECT TOE-IN


    1. Bounce the vehicle up and down at the corners to stabilize the suspension.

    2. Release the parking brake and move the shift lever to N.

    3. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)

    4. A01CBMME04

      Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

    5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180° using the front tire valve as a reference point.

      Tip:

      Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from Step C again.

    6. A01CBTTE01

      Measure the distance between the tread center marks on the front side of the wheels (dimension A).

      Table 1. To-in (Unloaded Vehicle)
      Item Specified Condition

      Toe-in

      (total)

      C + D: 0°06' +/- 0°12' (0.1° +/- 0.2°)

      B - A: 1.0 +/- 2.0 mm (0.0394 +/- 0.0787 in.)
      Tip:

      • Measure "B - A" only when "C + D" cannot be measured.

      • If toe-in is not within the specified range, adjust it at the rack ends.

    ADJUST TOE-IN


    1. A01CAR2

      Make sure that the length of the right and left rack ends are approximately the same.

      Standard difference
      1.5 mm (0.06 in.) or less

    2. Remove the boot clips.

    3. Loosen the tie rod end lock nuts.

    4. Turn the right and left rack ends by an equal amount to adjust the toe-in to the center value.

    5. Tighten the tie rod end lock nuts.

    6. Place the boots on the seats and install the clips.

      Tip:

      Make sure that the boots are not twisted.

    INSPECT WHEEL ANGLE


    1. Put tread center marks on the rearmost points of the turning radius gauge.

    2. Turn the steering wheel to the left and right full lock positions, and measure the turning angle.

      Wheel Angle (Unloaded Vehicle)
      Inside Wheel Outside Wheel Reference

      39°23' +/- 2°

      (39.38° +/- 2°)
