key is in this position. Do not leave the key in this
position unless the engine is running.

START

Turn the key clockwise to the second position and
release as soon as the engine starts. The key will
return to the ON position. If the engine did not
start, return the ignition key to the OFF position
before trying to restart the engine.
The ignition switch is equipped with a starter
protection which inhibits turning the key to the
START position if the key has not previously been
turned to the OFF position.
CAUTION
To avoid overheating the starter, do not engage
the starter for more than 15 seconds at a time.
Allow the starter to cool before trying to restart
the engine.
DANGER
Do not use ether or other combustible starting
aid fluid on any engine equipped with an intake
air preheater. If the engine is equipped with a
preheater, introduction of ether or similar starting
aids could cause a fire or explosion resulting in
severe property damage, serious personal injury
or death.

FOOT-OPERATED CONTROLS

FIGURE 4: FOOT OPERATED CONTROLS

BRAKE PEDAL

The coach is equipped with a dual braking system.
The front brakes operate from a different air source
than the drive and tag axle brakes.
The dual braking system becomes a modulated
emergency system if a pressure drop occurs in the
primary brake system (rear brakes).
Service brakes are applied by depressing the
brake pedal. Braking increases with the amount of
pressure applied to the foot pedal. Refer to
"ANTILOCK BRAKING SYSTEM (ABS)" on
page 27
brake pedal is depressed, the brake lights turn on
automatically.
For safe and effective braking, the air system
pressure should reach at least 95 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 circuit 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.
RETARDER" on page 12
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.
