6-2 Starting and Stopping Procedures
PA-1652 Operator's Manual H3-45 Coach
STARTING THE ENGINE
In normal circumstances, the engine should be
started from the driver’s seat. However, a rear-
start panel in the engine compartment allows
starting the engine from that location, typically for
maintenance operations. See "STARTING
FROM THE ENGINE COMPARTMENT" on the
facing page.
STARTING FROM THE DRIVER’S SEAT
1. Make sure the engine STOP interlock
button located in the engine
compartment is reset (twist and pull)
to enable starting from the driver's
and that the main electrical shut- off
switch is set to the ON position (see
images below).
2. Activate the ignition switch. See
"Ignition Switch" on page12 in
Controls and Instruments section.
3. Confirm the parking brake is applied;
4. Confirm the transmission is in neutral;
5.
Depress the brake pedal.
6.
Press the ENGINE START button.
See "ENGINE START BUTTON"
on page4 in Controls and
Instruments section.

NOTE
When the ignition is turned to ON, the M32QR
ABS Pressure Modulator Valve solenoids are
briefly energized. This can be audibly detected
by a rapid cycling of the PMVs. If the air system
is fully charged and the service brake pedal is
depressed when ignition is turned to ON, the
modulator valves create a sharp audible “chuff”
of air pressure.
CAUTION
Do not press the accelerator pedal before
starting. This could result in an electronic
control unit fault and degrade the fuel system
control.
