STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.

Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
Manual Transmission

TRAL and depress the clutch pedal before starting ve-
hicle. This vehicle is equipped with a clutch interlocking
ignition system. It will not start unless the clutch pedal is
pressed to the floor.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 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 of either a cold or a warm
engine is obtained without pumping or depressing 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.
Tip Start Feature — Automatic Transmission Only
Turn the ignition switch to 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 seconds. 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 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
seconds 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.
274 STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant 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
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.

Shift Lock 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 de-
pressed. To operate the shift lock manual override, per-
form the following steps:
1. Firmly set the parking brake.
2. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel, above the PARK position.
3. Depress and maintain firm pressure on the brake
pedal.
4. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.5. Depress the shifter release button and shift into NEU-
TRAL.
6. The vehicle may then be started in NEUTRAL.
Have your vehicle inspected by your local authorized
dealer, if the shift lock manual override has been used.
280 STARTING AND OPERATING

Brake/Transmission Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first, before moving the shift lever out of PARK.
Automatic Transmission with Overdrive
Shifting from DRIVE to PARK or REVERSE (or from P or
R to D) should be done only after the accelerator pedal is
released and the vehicle is stopped. Be sure to keep your
foot on the brake when moving the shift lever between
these gears.

NEUTRAL position into another gear range.

PARK
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply parking brake first,
then place the shift lever in the PARK position.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
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 right foot is
firmly on the brake pedal.
REVERSE
Use this range only after the vehicle has come to a
complete stop.
NEUTRAL
Shift into NEUTRAL when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
