STARTING AND STOPPING PROCEDURES 6-3
PA1633 X3-45 Commuter Operator’s Manual
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.
4. The transmission pushbutton shift
selector automatically selects
neutral (N) when the ignition switch
is turned to ON;
5. With your foot off the accelerator
pedal, turn ignition lever to the
“START” position.(refer to Controls
and Instruments chapter)
6. Brake pedal must be applied when
selecting Drive (D) otherwise the
transmission will stay in neutral (N).
CAUTION
Do not engage starter for more than 15
seconds at a time. If engine does not start
within 15 seconds, release engine start lever
and let starter cool for one minute before
attempting to restart.
CAUTION
Do not press accelerator pedal before starting.
This could result in an electronic control unit
fault and degrade the fuel system control.
CAUTION
Special precautions are necessary with
turbocharged engines to avoid possible
turbine damage. After starting, run the engine
at normal idle for two minutes to allow
lubricating oil to reach the turbocharger then
run the engine at fast idle. Let oil pressure
reach normal operating range before driving.
NOTE
If engine does not start, return ignition lever to
OFF position before attempting to restart.
NOTE
If the accelerator pedal is depressed before
starting, release and wait 30 seconds before
attempting to restart
.
Stopping the Engine
1. Apply parking brake and place
transmission in neutral (N);
2. Allow engine to idle for at least two
minutes before shutting engine OFF.
This insures that the turbine speed
drops and allows time for the engine
exhaust gas temperature to drop to
about 300
o
F (150
o
C);
3. Shut off all electrical loads;
4. Turn the ignition switch to the OFF
position.
CAUTION
Do not shut OFF engine when running above
normal idle.
CAUTION
Turn the battery master switch (master cut-
out) to the OFF position after parking and
when left unattended for an extended period
of time.
