description of function
Air suspension vehicle height initial adjustment
To absorb weight fluctuations of the body, the initial
settings to store the normal vehicles height position must
always be done after mounting the rear body and with the
vehicle empty at the dealership prior to vehicle delivery.
For air-suspension vehicles, it is possible to adjust the
normal vehicle height position to any position, but to
ensure correct vehicle posture and to limit damage to
cargo, it is necessary to achieve the proper suspension
stroke.
