SECTION 4 – ENGINE OPERATION
1. Set parking brake and shift transmission to park or neutral.
CAUTION
To prevent damage to the engine, do not depress
the accelerator pedal.
2. Depress clutch pedal if equipped.
3. Turn ignition switch to ON to activate the cold start assist
/ inlet air heater system. The WAIT TO START lamp will
illuminate continuously. Do not crank engine while lamp is
on continuously.
NOTE: The ECM normally does not energize the inlet air
heater element during hot starts. However, the ECM senses
reduced atmospheric pressure at high altitude and could
energize the air heater element during hot starts.
4. When the WAIT TO START lamp begins flashing, turn
ignition switch to START. If the vehicle has pushbutton
starting, press and hold starter button.
5. When the engine starts, release the ignition switch or starter
button. The ignition switch will return to ON and the engine
will continue to run.
6. With the transmission in neutral, release clutch pedal if
equipped.
7. Until oil pressure is achieved, the engine will not accelerate
and the WAIT TO START lamp will flash.
CAUTION
If the engine fails to start within 30 seconds, to
prevent damage to the engine, do the following:
• Turn ignition switch to OFF and wait 2 - 3
minutes.
• Repeat Steps 1 through 5.
• If after three attempts the engine does not start,
determine the cause.
• If starting attempts are continued, the starter
motor can be damaged.
8. Low idle speed is 700 rpm (nonadjustable). Extended idling
periods should be avoided. See Extended Idling Periods in
this section. Check all gauges during warm-up.
9. Within 20 seconds after engine start, engine oil pressure
should exceed 15 psi (103 kPa).
CAUTION
To prevent engine damage – do not increase
engine speed until oil pressure gauge indicates
above 15 psi (103 kPa). If oil pressure does not
reach the minimum limit within 20 seconds, shut
down the engine.
