formation on how to operate the controls. Read
the operating instructions in the manufacturer's
engine operation manual 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.
1. Before engine start-up, complete the pretrip in-
spections and maintenance procedures in
ter 11.
2.
Set the parking brake.
3. For manual transmissions, place the transmis-
sion in neutral and fully depress the clutch pedal.
Do not depress the accelerator pedal.
For automatic transmissions, put the transmis-
sion in neutral. Do depress the accelerator 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 ON. See
The following actions should occur:
•
electronic gauges complete a full sweep of
their dials
•
warning and indicator lamps illuminate,
then are extinguished
•
DEF level indicator illuminates all seg-
ments green, then turns them off one at a
time before turning the leftmost segment
amber and then red
•
During cold conditions, the WAIT TO
START lamp may illuminate.
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
if oil pressure does not build within approxi-
mately ten seconds. Check to determine the
cause of the problem. Operating the engine with
no oil pressure will damage the engine.
6. It is not necessary to idle the engine before en-
gaging or starting the operation, but load should
be applied gradually during the warm-up period
until the oil temperature reaches 140°F (60°C).
7. Apply load gradually during the warm-up period.
NOTICE
If the oil pressure gauge indicates no oil pres-
sure, shut down the engine within approximately
ten seconds to avoid engine damage.
8. Check the oil pressure gauge for any drop in lu-
bricating oil pressure or mechanical malfunction
in the lubricating oil system. Minimum oil pres-
sure at idle is 7 psi (50 kPa).
