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 Chap-
ter 3 , Instruments , and Chapter 4 , Driver
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: The New Cascadia vehicle is
equipped with starter interlocks to enhance reli-
ability 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 deter-
mined by the protection logic. If the engine is
turning, the starter will not engage. Depending
on the transmission option, the starter will not
engage if the clutch is not fully depressed, or if
the transmission 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 25 .
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 STARTER
BLOCKED function.
4. Turn the ignition switch to the ON position and
allow the self-check to complete. See
Fig. 12.1 .
NOTE: The driver display screen may present a
STARTER BLOCKED message if the gauge
sweep is not completed, the transmission is in
gear, or the starter has overheated.
5. Once the gauge sweep has completed, turn the
ignition key to the START position. Release the
key the moment the engine starts.
If the vehicle is equipped with an engine start
switch (see
Fig. 12.2 ), hold the switch down
while turning the ignition key to the START posi-
tion. Release the switch and 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
