DANGER
Immediately report any brake system problem
to the nearest Prevost or Prevost-authorized
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.
NOTE
The accelerator pedal will not operate when
the front door is open.
ALLISON TRANSMISSION

ranges
should be automatically selected
according to driving speeds to improve vehicle

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
