to the emergency fill valve in the engine R.H.
side compartment. The emergency fill valve
in the front service compartment does not
supply air pressure to the brake system. The
air pressure must be a minimum of 75 psi
(520 kPa), and the line should be attached to
the air line with a clip-on chuck.
CAUTION
Do not tow the vehicle without external air
pressure applied to the emergency fill valve
if the engine does not operate. Without
brake system air pressure, the brakes may
apply automatically if system air drops
below 40 psi (275 kPa). If failure prevents
releasing the parking brakes with air
pressure, disengage the parking brakes
mechanically.
