STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle.4WD Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.
220 STARTING AND OPERATING

Normal Starting — Gasoline Engines
Normal starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the normal starting procedure.

WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
If Engine Fails to Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
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.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
222 STARTING AND OPERATING

If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed is automatically controlled and will de-
crease as the engine warms up.
Normal Starting — Diesel Engines
1. Turn the ignition key to the ON/RUN position.
2. Watch the “Glow Plug Indicator Light.” It will stay on
for a maximum of 2 seconds, depending on engine
temperature. When the “Glow Plug Indicator Light” goes
out, the engine is ready to start.
3.Do notpress the accelerator. Turn the ignition key to
START and hold it in this position until the engine starts.
Starting and Operating Cautions — Diesel Engines
•
Under normal conditions,do notoperate the starter
for longer than 20 seconds at one time. At tempera-
tures below 5°F (
15°C), you may operate the starter
for up to 25 seconds at one time. Longer periods of
operation may result in starter or battery damage. If
the engine does not start at once, repeat Steps 1
through 4.
•Cold engine speeds higher than necessary for driving
or higher than specified for idling may damage engine
components.
•Before turning off your Diesel engine, always allow
the engine to return to normal idle speed and then run
for several seconds. This assures proper lubrication of
the turbocharger. This is particularly necessary after
periods of high speed driving.

Turbocharger “Cool Down”
NOTE:Letting the engine idle after extended operation
allows the turbine housing to cool to normal operating
temperature.
The following chart should be used as a guide in deter-
mining the amount of engine idle time required tosufficiently cool down the turbocharger before shut
down, depending upon the type of driving and the
amount of cargo.
