   Standard Steering Axis Inclination (Unloaded Vehicle)

   Suspension Package Option	Steering Axis Inclination : Reference
   Active Height Control - NORMAL	13°00' +/-45' (13.00° +/-0.75°)
   Active Height Control - LOW	14°50' +/-45' (14.83° +/-0.75°)
   Active Height Control - HIGH	11°58' +/-45' (11.96° +/-0.75°)

   HINT: 

   The steering axis inclination is a reference value.

HINT: 

After the camber has been adjusted, inspect the toe-in.

1. Loosen the front adjusting cam bolt and rear adjusting cam nut.
2. Turn the front adjusting cam and rear adjusting cam in both directions, and adjust the camber and caster to the center value.

   HINT: 

   • The camber and caster should be as close as possible to the center value.
   • Make sure the difference between the left and right camber and caster is within +/-30' (0.5°).

   Read the adjustment chart (example).

   1. Find the wheel alignment standard value applicable for the particular model.
   2. Mark the selected standard value on the adjustment chart.

      Standard Value (Reference)

      Camber	Caster
      0°00' (0.00°)	4°00' (4.00°)

   3. Mark the alignment value measured when the vehicle is unloaded on the adjustment chart.

      Measured Value (Reference)

      Camber	Caster
      0°11' (0.18°)	4°38' (4.63°)

   4. As shown in the chart, read the distance from the marked point to 0, and adjust the front and / or rear adjusting cams accordingly.

   Front of the Vehicle

   Standard Toe-in (Unloaded Vehicle)

   Toe-in (total)
   A + B	C - D
   0°00' +/-10' (0.00° +/-0.17°)	0.0 +/-2.0 mm (0 +/-0.0787 in.)

   If the toe-in is not as specified, adjust it at the rack ends.

   HINT: 

   The toe-in can be measured using either A + B or C - D.

1. Release the rack boot set clips.
2. Loosen the tie rod end lock nuts.
3. Turn the right and left rack ends by an equal amount to adjust the toe-in to the center value.
4. Check that the length of the right and left rack ends are approximately the same.

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

   HINT: 

   Make sure that the boots are not twisted.

7. Perform the VGRS system calibration. Refer to INITIALIZATION [09/2015 - ] .

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

   Standard Wheel Turning Angle (Unloaded Vehicle)

   Suspension Package Option	Steering Axis Inclination : Reference	Outside Wheel Angle : Reference
