Dual Air Pressure Gauge (Air Reservoir)
The dual air pressure gauge indicates the amount of air pres-
sure in the brake system in pounds per square inch (psi). The
WHITE pointer shows the front (secondary service) reservoir
air pressure, and the ORANGE pointer indicates pressure in
the rear (primary service) reservoir.
If the pressure in either or both circuits is too low for normal
brake operation (below 64 psi), a warning light in the panel
will glow and the audible alarm will sound.
WARNING! 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.
