WARNING
The vehicle must never be driven with
the air springs deflated. Damage to air
suspension parts will occur if springs are
not inflated properly.
Tractors with air suspension have a control
for deflating the air springs. This is used
when uncoupling from trailers. See page
192 for correct operation when uncoupling.
A telltale in the instrument cluster will light
up when the switch is in the "on" position.
