Extreme Cold Weather (below
or 29°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.

If Engine Fails To Start

If the engine fails to start after you have fol-
lowed the "Normal Starting" or "Extreme Cold
Weather" procedures, it may be flooded. Push
the accelerator pedal all the way to the floor
and hold it there. Crank the engine for no more
than 15 seconds. This should clear any excess
fuel in case the engine is flooded. Leave the
ignition key in the ON position, release the
accelerator pedal and repeat the "Normal
Starting" procedure.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an attempt
to start the vehicle. This could result in flash
fire causing serious personal injury.
148
20°F
CAUTION!
To prevent damage to the starter, do not crank
the engine for more than 15 seconds at a
time. Wait 10 to 15 seconds before trying
again.

After Starting

The idle speed will automatically decrease as
the engine warms up.
Normal Starting – Diesel Engine
1. Apply the brake, press the clutch pedal to
the floor, shift the transmission into NEUTRAL
and turn the ignition key to the ON position.
NOTE:
The engine will not start unless the clutch
pedal is pressed to the floor.
2. Watch the "Wait To Start Light." It will glow
for two to 10 seconds or more, depending on
engine temperature. When the "Wait To Start
Light" turns off, the engine is ready to start.
3. Do not press the accelerator. Turn the igni-
tion key to the START position and hold it in this
position until the engine starts.
CAUTION!
• Under normal conditions, do not operate
the starter for longer than 15 seconds at
one time. At temperatures below –5°F
( 15°C), you may operate the starter for up
to 30 seconds at one time. Longer periods
of operation may result in starter or battery
damage. If the engine does not start at
once, repeat the procedures under "Normal
Starting – Diesel Engine".
• Cold engine speeds higher than necessary
for driving or higher than specified for idling
may damage engine components.
Starting If Engine Has Run Out of Fuel
To restart the diesel engine after running out of
fuel, turn the ignition key to the ACC (Acces-
sory) position approximately eight seconds
prior to cranking the engine. Several attempts
of 10 second crank times may be required.
