STARTING AND OPERATING 275

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 buildup may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the shift lever in NEU-
TRAL, and press the clutch pedal before starting the
vehicle. This vehicle is equipped with a clutch interlock-
ing ignition system. It will not start unless the clutch
pedal is pressed to the floor.
Four-Wheel Drive Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This featureenhances off-road performance by allowing the vehicle to
start when in 4L without having to press the clutch pedal.
The “4WD Indicator Light” will illuminate when the
transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.

STARTING AND OPERATING 277

Tip Start Feature — Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (below –20°F or –29°C)
To ensure reliable starting at these temperatures, use of
an externally-powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails to Start
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.(Continued)
278 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, repeat the “Normal Starting” or “Ex-
treme Cold Weather” procedures.
With Tip Start — Automatic Transmission Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
280 STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord. The engine block
heater cord is found under the hood bundled in front of
the battery tray.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
CAUTION!
Never drive with your foot resting on the clutch
pedal, or attempt to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch.

STARTING AND OPERATING 281

AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your foot is
firmly on the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key to the LOCK position. The key
can only be removed from the ignition when the ignition
is in the LOCK position and once removed the shift lever
is locked in PARK.

STARTING AND OPERATING 285

Brake/Transmission Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the key in the ON position and the brake pedal pressed.
To operate the shift lock manual override, perform the
following steps:
1. Turn the key to the ON position but do not start the
engine.
2. Firmly set the parking brake.3. Using a flat-bladed screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel, above the PARK position.
4. Press and maintain firm pressure on the brake pedal.
5. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.
