The alignment machine should be checked to ensure that it is level. 2. Make sure the alignment machine is properly calibrated. Your alignment machine should be regularly calibrated in order to give correct information. Check with the manufacturer of your specific alignment machine for their recommended Service/Cali- bration Schedule. THE ALIGNMENT PROCESS IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-18, " Front Wheel Alignment (Unladen*1) " . 1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do NOT use these indicators. The alignment specifications programmed into your alignment machine that operate these indicators may not be correct. This may result in an ERROR. 2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation” method. Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways. See Instructions in the alignment machine you are using for more information. CAMBER, CASTER AND KINGPIN INCLINATION NOTE: Camber, caster and kingpin inclination are preset at factory and cannot be adjusted. 1. Measure the camber, caster and kingpin inclination of both the right and left wheels using attachment Tool and a suitable align- ment gauge. 2. If the camber, caster or kingpin inclination is not within specifica- tion, inspect the front suspension parts. Replace any damaged or worn out parts. TOE-IN WARNING: Always perform the following procedure on a flat surface. Make sure that no person is in front of the vehicle before pushing it. 1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture). 2. Push the vehicle straight ahead about 5 m (16 ft). Camber, caster and kingpin inclination : Refer to FSU-18, " Front Wheel Alignment (Unladen*1) " . SRA096A
