WARNING! Low air pressure could make the<br />
brakes unsafe for driving. Before driving the<br />
vehicle, make sure the pressure does pump<br />
up to over 100 psi for normal brake operation.<br />
If the air pressure does not pump up to at<br />
least 100 psi, don’t try to move the vehicle as<br />
it may cause an accident, possibly resulting in<br />
death or personal injury.<br />
CAUTION: Operating a vehicle with air suspension<br />
bags either overinflated or underinflated<br />
may cause damage to driveline<br />
components. If a vehicle must be operated<br />
under such conditions, do not exceed 5 mph.<br />

speeds. At very high speeds you may not be<br />
able to put the transmission in any gear. At<br />
high speeds you could seriously damage your<br />
vehicle or cause an accident when you put the<br />
transmission in gear. The engine speed could<br />
exceed the maximum governed speed and<br />
cause a serious accident, resulting in death or<br />
