PB1318 3/01 Model 330
WARNING! If the air pressure falls below 60 psi
(414 kPa) the spring brakes may stop the vehicle
abruptly, which could result in an accident and/
or injuries. Observe the warning light in the
panel. If it comes on, do not continue to drive the
vehicle until it has been properly repaired or ser-
viced.
WARNING! The air pressure warning light and
the audible alarm indicate a dangerous situa-
tion: there is not enough air pressure in the res-
ervoirs for repeated braking and the brake
system has failed. Without the use of your ser-
vice brakes, your spring brakes could suddenly
apply. This could cause a wheel lock-up, loss of
control, or over-take by following vehicles. You
could be in an accident and severely injured.
• Bring the vehicle to a safe stop right away, while you
still have control of the vehicle.
Air Loss Emergency Procedure
1. Slow down carefully.
2. Move a safe distance off the road and stop.
3. Place the transmission in park and set the parking brake.
(See Pages
65
and
72
for transmission shifting and park-
ing brake information.)
4. Turn OFF the engine.
5. Turn ON the emergency flasher (See
“Emergency
Flasher Switch” on page 52
) and use other warning
devices to alert other motorists.
