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.
Automatic Transmission
Start the engine with the selector lever in the ªNº
(Neutral) or ªPº (Park) position. Apply the brake before
shifting to any driving range.
Manual Transmission Ð If Equipped
Apply the parking brake, place the gearshift control lever
in ªNº (Neutral) and depress the clutch pedal beforestarting vehicle. 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
To enhance off-road performance, 4-wheel drive models
equipped with a manual transmission will start with or
without pressing the clutch pedal when in 4-wheel drive
low range. The 4 LOW indicator light will illuminate
when the transfer case is in 4-wheel drive low range.
Normal Starting
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
For vehicles not equipped with Tip Start,turn the ignition
switch to the START position and release it 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
5

For vehicles equipped with Tip Start,turn the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will continue to run,
and it will disengage automatically 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 ±20ÉF or ±29ÉC)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
If Engine Fails to Start
WARNING!
²Never 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.
²Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
278 STARTING AND OPERATING

AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
²Shift into ªPº (Park) only after the vehicle has
come to a complete stop.
²Shift into or out of ªRº (Reverse) only after the
vehicle has come to a complete stop and the engine
is at idle speed.
²Do not shift from ªRº (Reverse), ªPº (Park), or ªNº
(Neutral) into any forward gear when the engine is
above idle speed.
²Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to shift the selector lever out of ªPº
(Park) or ªNº (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 ªRº (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.
Shift Lock Manual Override Ð If Equipped
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 ªPº (Park)
with the key in the ON position and the brake pedal
depressed. To operate the shift lock manual override,
perform the following steps:

Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of ªPº (Park) and into any gear unless the brake pedal is
pressed. Always depress thebrake pedal first,before
moving the gear selector out of ªPº (Park).
4±Speed Automatic Transmission
Shifting from ªDº (Drive) to ªPº (Park) or ªRº (Reverse)
(or from ªPº or ªRº to ªDº) 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
selector lever between these gears.
Gear Ranges
DO NOT race the engine when shifting from ªPº (Park)
or ªNº (Neutral) position into another gear range.

ªNº (Neutral)
Shift into ªNº (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.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with selector lever in ªNº (Neutral) can
result in severe transmission damage. Refer to ªRecre-
ational Towingº in Section 5 and ªTowing a Disabled
Vehicleº in Section 6 of this manual.
ªDº (Drive)
For most city and highway driving.
ª2º (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.ª1º (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth speed (Overdrive). The trans-
mission will automatically shift from 3rd gear to Over-
drive if the following conditions are present:
²The transmission selector is in ªDº (Drive).
²The vehicle speed is above approximately 30 mph (48
km/h).
²The ªTOW/HAULº button has not been activated.
STARTING AND OPERATING 285

NOTE:
²If the vehicle is started in extremely cold temperatures,
the transmission may not shift into Overdrive. It will
however, automatically select the most desirable gear
for operation at this temperature. Normal operation
will resume when the transmission fluid temperature
has risen to a suitable level.
²If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
ªTransmission Temperature Warning Lightº may illu-
minate, and the transmission may downshift out of
Overdrive until the transmission cools down. After a
cool down, the transmission will resume normal op-
eration.The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use ªTOW/HAULº Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, the transmission will
shift to 3rd gear.
NOTE:ªTOW/HAULº mode locks out Overdrive.
