ADJUSTMENT

CAUTION / NOTICE / HINT

NOTICE:

If a wheel alignment has been performed, or 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:

  • Perform zero point calibration of the yaw rate and acceleration sensor.

PROCEDURE

1. INSPECT TIRES

3. INSPECT CAMBER

*a

Gauge

(a) Install a camber-caster-kingpin gauge or set the vehicle on a wheel alignment tester.

(b) Inspect the camber.

Standard Camber Inclination (Unloaded Vehicle):

Tire Size

Camber Inclination

Right-left Difference

225/65R17

-1°15' +/-45' (-1.25° +/-0.75°)

45' (0.75°) or less

225/60R18

-1°20' +/-45' (-1.33° +/-0.75°)

45' (0.75°) or less

  • If the measured value is not within the specified range, inspect the suspension parts for damage and wear. Replace parts as necessary as the camber cannot be properly adjusted with any damaged or worn parts.

4. INSPECT TOE-IN

(a) Bounce the vehicle up and down at the corners to stabilize the suspension and inspect toe-in.

Front of the Vehicle

Toe-in (Unloaded Vehicle):

A + B

C - D

A + B: 0°10' +/-10' (0.16° +/-0.16°)

C - D: 2.0 +/-2.0 mm (0.08 +/-0.08 in.)

HINT:

If the toe-in is not within the specified range, inspect the suspension parts and replace them if necessary.

5. ADJUST TOE-IN

(a) Loosen the toe adjust cam nut.

(b) Turn the adjust cams by an equal amount to adjust the toe-in.

Toe-in (Unloaded Vehicle):

-

A + B

C - D

Toe-in

(Total)

A + B: 0°10' +/-10' (0.16° +/-0.16°)

C - D: 2.0 +/-2.0 mm (0.08 +/-0.08 in.)

HINT:

  • Try to adjust the toe-in to the center value.
  • The toe-in will change by approximately 3.6 mm (0.142 in.) for each gradation of the cam.
  • Perform adjustments so that the value is as close as possible to the median of the specified range.

(c) Tighten the toe adjust cam nut.

Torque:

120 N·m {1224 kgf·cm, 89 ft·lbf}
