Engine Shutdown System (Option)
Your truck may be equipped with the optional engine shutdown
system. This system continually monitors engine coolant
temperature and oil pressure to protect the engine from
dangerous conditions.
• After the engine starts, a warning alarm sounds; this is
normal because of the lack of oil pressure when first
starting the engine. As soon as oil pressure increases,
the buzzer turns off.
• During engine operation, if the oil pressure drops below
idle pressure or the coolant temperature climbs to a dangerous
level, the engine will shut down automatically—
sounding the alarm and turning the appropriate warning
light on.
Operating the Engine
• If the engine shuts down automatically or if the buzzer
and light turn on while the engine is running, drive the
vehicle to a safe stop off the highway to investigate the
problem.
CAUTION: Do not re-start your engine unless it
is necessary to move your truck to a safe location.
The low oil pressure or high engine temperature
condition could cause serious engine
damage.

• If it’s necessary to move the vehicle, hold the manual
override switch up while starting your engine. The alarm
will continue to sound.
• Operate the engine as little as possible until you have it
serviced at an Authorized Service Center.
