Engine Starting, Operation, and Shutdown

Engine Starting
This engine chapter is to serve as a guide for best
practices only. Each engine model may have operat-
ing characteristics that are unique to that particular
engine, and will be documented in the engine manu-
facturer's literature. Always refer to specific instruc-
tions and recommendations from the engine manu-
facturer.
NOTE: Before starting the engine, read
ter 4, Instruments, and
Controls. Read the engine manufacturer's oper-
ating instructions before starting the engine.
WARNING
Never pour fuel or other flammable liquid into the
air inlet opening in the air intake in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury or property
damage.
IMPORTANT: Cascadia vehicles are equipped
with starter interlocks to enhance reliability and
safety. Anti-grinding, starter pinion, and thermal
protection logic limit the amount of time and
conditions for starter engagement. Cranking
may be limited from 5 to 15 seconds, with a 30-
second cool-down period, as determined by the
protection logic. If the engine is turning, the
starter will not engage. Depending on the trans-
mission option, the starter will not engage if the
clutch is not fully depressed, or if the transmis-
sion is not in neutral.
IMPORTANT: The starter can not be used for
priming the fuel system. If the fuel/water separa-
tor filter is replaced, and the fuel system needs
to be primed, see the engine manufacturer's
operating instructions.
1. Before engine start-up, complete the pre- and
post-trip inspections and maintenance proce-
dures in Chapter 21.
2.
Set the parking brake.
3. Place the transmission in neutral. On vehicles
with manual transmissions, fully depress the
clutch pedal.

NOTE: Depending on local jurisdictional emis-
sions regulations, vehicles and/or engines that
are domiciled outside of the U.S. and Canada
may not be equipped with the WAIT TO START
or START BLOCKED lamp.
4. Turn the ignition switch to the ON position and
allow the gauge sweep to complete. See
Fig. 10.1. The audible alert will sound for ap-
proximately four seconds.
During cold conditions, the WAIT TO START
lamp may illuminate. Wait until the lamp goes out
before turning the ignition key to START.

NOTE: The length of time the WAIT TO START
lamp remains illuminated depends on the ambi-
ent temperature. The lower the ambient tem-
perature, the longer the lamp will be illuminated.
NOTE: If the ignition switch is turned to START
before the gauge sweep has completed or if the
starter has overheated, the START BLOCKED
lamp may illuminate. Turn the ignition switch
back to ON, wait for the lamp to go out, then
turn the ignition switch to START again.
5. Once the gauge sweep has completed, turn the
ignition key to the START position. Release the
key the moment the engine starts.
NOTICE
Do not rev the engine if the oil pressure gauge
indicates no oil pressure. Shut down the engine
