Front Wheel Alignment: Adjustment: Adjustment

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:

Disconnect the cable from the negative (-) battery terminal for more than 2 seconds.
Reconnect the cable to the negative (-) battery terminal.
Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.

INSPECT TIRES . Refer to INSPECTION - Step 1

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.

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

Measure the vehicle height.

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

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

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

HINT:

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

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