Peterbilt 365 2017, Manual

Page: 105 / 228

STANDARD GAUGES
Ensure the air pressure registers more
than 100 psi in both service systems
before you move the vehicle. If the
pressure in either circuit is too low for
normal brake operation, the warning
light will glow and the audible alarm
will sound.
WARNING!
The air pressure warning light and
the audible alarm indicate a danger-
ous situation. There is not enough
air pressure in the reservoirs for re-
peated braking and the brake sys-
tem has failed. If air pressure falls
below 60 psi (414 kPa) the spring
brakes could suddenly apply, caus-
ing a wheel lockup, loss of control,
or your vehicle to be overtaken by
following vehicles. You could be in
an accident and severely injured. If
these alarms come on while you are
driving, bring your vehicle to a safe
stop right away. If the light and alarm
do not turn off at start-up, do not try
to drive the vehicle until the problem
is found and fixed.
Diesel Exhaust Fluid (DEF)
Gauge
The diesel exhaust fluid gauge shows
the approximate amount of DEF fluid
in the DEF tank. Besides empty and
full, the gauge also indicates 1/4, 1/2,
and 3/4 of total capacity. DEF fluid
is required to meet certain emission
requirements. Maintain an adequate
amount of diesel exhaust fluid at all
times, as provided in the aftertreatment
system operator manual. Please refer
to the aftertreatment operator manual
for more details about DEF fluid.
