SUSPENSION
Driving with Deflated Air
Springs
If an air spring is ruptured, there will
be enough air pressure to drive the
vehicle to a safe stop off the highway
to investigate the problem.
WARNING!
Do not continue to drive with rup-
tured air springs. The air loss can
cause the spring brakes to apply al-
lowing your brakes to drag and burn
up the linings, which could lead to an
accident causing death or personal
injury. Do not continue to operate
the vehicle in this condition.
You can get to a repair facility if you do
the following:
1. Remove the height control link
connected to the axle and to
the suspension air valve control
arm. This will cause the air valve
control arm to center in the closed
position.
2. The air system can then be
pumped up to normal pressure for
continued operation.
WARNING!
Do not drive the vehicle if the air
pressure is less than 100 psi (690
kPa). Driving the vehicle with less
than 100 psi (690 kPa) could make
the brakes unsafe to use which
could cause an accident involving
death or personal injury.
CAUTION
Operating a vehicle with air suspen-
sion bags either overinflated or un-
derinflated may cause damage to
driveline components. If a vehicle
must be operated under such condi-
tions, do not exceed 5 mph (8 km/h).
