Alignment Specifications

NOTE:

For air suspension equipped vehicles, when checking or adjusting wheel alignment, the air suspension system must be set to Wheel Alignment Mode. The preferred method of setting the system to Wheel Alignment Mode is through the diagnostic scan tool. Wheel Alignment Mode in the radio menu can also be used if a diagnostic scan tool is not available.

NOTE:

All non-air suspension equipped vehicles are to be aligned at curb height. Refer to WHEEL ALIGNMENT, STANDARD PROCEDURE .

NOTE:

On air suspension equipped vehicles the ride height specifications apply to vehicles set to NRH (Normal Ride Height).
