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

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
page 27 in Section 5 Other Features . When the
brake pedal is depressed, the brake lights turn on
automatically.
SYSTEM (ABS)" on
PA-1638 Owner's Manual X3-45 VIP
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. Refer to
"TRANSMISSION RETARDER" on page 10
section.
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
effectiveness but rather reduces system air
pressure thereby causing
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.
CAUTION
Do not let the engine operate above 2,450 rpm.
STEERING WHEEL ADJUSTMENT UNLOCK
AIR VALVE
Push on the valve button with the left foot to unlock
the steering wheel for tilt and telescopic adjustment.
WARNING
Do not adjust the steering wheel while the vehicle
is moving. Loss of control could result. Park the
vehicle safely and apply parking brake before
adjusting.
