System. When the brake pedal is depressed,
the brake lights turn
ON automatically.
For safe and effective braking, the air system
pressure should reach at least 122 psi in both
the primary and secondary circuits. A warning
light and an audible alert will sound when the air
pressure in either the primary or secondary
circuits drops below 85 psi. If this occurs, stop
the coach; determine the cause of the pressure
loss before proceeding. The brake pedal can be
used in conjunction with the transmission
retarder. Refer to Transmission Output Retarder
in this chapter.
DANGER
Immediately report any brake system problem
to your company or directly to the nearest
prevost or prevost-approved service center.
Do not "fan" or "pump" the brake pedal. This
practice does not increase brake system
effectiveness but rather reduces system air
pressure thereby causing reduced braking
effectiveness.
CAUTION
"Riding" the brake by resting one's foot on the
brake pedal when not braking can cause
abnormally high brake temperature, can
damage and cause premature wear of brake
components and reduce brake effectiveness.
ACCELERATOR PEDAL
Controls engine RPM as needed.

Allison Transmission
The transmission is fully automatic: Proper
ranges should be automatically selected
according to driving speeds to improve vehicle
performance and control. The speed ratio of the
power converter changes automatically as
vehicle speed increases and direct-drive goes in
and out as necessary. The speed ratio is
modulated by vehicle speed and accelerator
pedal position. You will find the complete
transmission operation instructions and driving
tips in the
