STARTING A DIESEL ENGINE

WARNING
Operation of a diesel engine near
flammable vapors in the air may
cause the engine speed to increase
uncontrollably and over speed. If this
situation occurs, mechanical damage, fire,
explosion, personal injury or death could
result. Turning off the ignition key does not
slow or stop the engine due to
uncontrollable fueling of the engine
through flammable vapors being drawn
into the engine air inlet. Operation of
components, for example starter,
alternator, electric motors and static
electricity could also ignite flammable
vapors. Do not operate your vehicle in the
possible presence of flammable vapors
unless both a complete hazard analysis is
carried out and necessary additional safety
processes and/or equipment, for example
vapor testing, air intake shutoff devices
and ventilation are utilized. You are
responsible for using those processes
and/or equipment to make sure that the
diesel engine and all other components on
your vehicle can be operated safely under
the specific conditions and hazards that
may be encountered.
Read all starting instructions carefully
before you start your vehicle.

Diesel Engine Fast Start Glow Plug
System
The diesel engine glow system consists of:
Eight glow plugs (one per cylinder)
Glow Plug Control Module
Engine Coolant Temperature sensor
Barometric pressure sensor
Environmental temperature sensor
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on the glow plug control module
immediately energizes the glow plugs. The
glow plug control module using the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor will determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.
Before starting the engine, check the
following:
Make sure all occupants have fastened
their safety belts.
Make sure the headlamps and
electrical accessories are off.
Make sure the parking brake is on.
Make sure the transmission is in park
(P) or neutral (N).
Turn the ignition key to the on position.
Note: Do not press the accelerator during
