INSPECTION
CAUTION / NOTICE / HINT
NOTICE:
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:
- Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.
PROCEDURE
1. INSPECT TIRES

3. INSPECT CAMBER
(a) Install the camber-caster-kingpin gauge and position the rear wheel on the turning radius gauge.
(b) Inspect the camber.

NOTICE:
- Inspect while the vehicle is unloaded.
- The tolerance for the difference between the left and right wheels is 0°30' (0.5°) or less for both cambers.
If the camber is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.
4. INSPECT TOE-IN
(a) Bounce the vehicle up and down at the corners to stabilize the suspension.
(b) Release the parking brake and move the shift lever to N.
(c) Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step A)
(d) Put tread center marks on the rearmost points of the rear wheels and measure the distance between the marks (dimension B).

(e) Slowly push the vehicle straight ahead to cause the rear wheels to rotate 180° using the rear tire valve as a reference point.
NOTICE:
Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from (Step A) again.
(f) Measure the distance between the tread center marks on the front side of the wheels (dimension A).

HINT:
Measure "B - A" only when "C + D" cannot be measured.
If the toe-in is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.
