WHAT TO DO IF...
WARNING!
If the air pressure falls below 60
psi (414 kPa) the spring brakes
may stop the vehicle abruptly, which
could cause an accident resulting
in death or personal injury.
Ob-
serve the red warning lamps on the
gauges. If one comes on, do not
continue to drive the vehicle until it
has been properly repaired or ser-
viced.
If the light and alarm do not turn off at
startup, do not try to drive the vehicle
until the problem is found and fixed.
(Refer to Using the Brake System on
page 4-24, for more brake information.)

jury.
