pressure should reach at least 122psi (841 kPa)
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 75 psi (517 kPa).
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.
ACCELERATOR PEDAL
Controls engine RPM as needed.
Allison Transmission
The transmission is fully automatic: Proper
ranges should be automatically selected accord-
ing to driving speeds to improve vehicle perfor-
mance 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 opera-
tion instructions and driving tips in the
Allison
included in your vehicle’s publication box.
OPERATION
When a button is depressed on the transmission
control pad, the corresponding letter or number
is displayed indicating the transmission is ready
to operate in the selected range. If the transmis-
sion control module (TCM) detects a serious
problem in the transmission, the CHECK telltale
lights on the dashboard.

PUSHBUTTON SHIFT SELECTOR
The pushbutton shift selector has the following
elements:
R
: Press to select Reverse gear.
N
: Press to select Neutral.
D
: Press to select Drive. The highest forward
range available will appear in the digital display
window under SELECT. The transmission will
start out in the lowest available forward range,
displayed under MONITOR, and advance auto-
matically to the highest range.
: Press respectively the
(Upshift) or
(Downshift) arrow button when in DRIVE to re-
quest the next higher or lower range. One press
changes gears by one range. If the button is
held down, the selection will scroll up or down
until the button is released or until the highest or
lowest possible range is selected. Protection
mechanisms inhibit selecting ranges that are not
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.
!
"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.
