Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
Audio System
Wipers
Power Windows
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, power to these features
continue to work for up to 20 minutes or until a door is
opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
when you are already moving, use N (Neutral) only.
Notice:Do not try to shift to P (Park) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. Your vehicle will not
start if the clutch pedal is not all the way down. That is
a safety feature.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up
and lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent engine
coolant heater operation at temperatures above
0°F (-18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver’s side
of the vehicle.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.

Automatic Transmission Operation
Your automatic transmission has a shift lever on the
steering column.
It features an electronic shift position indicator within the
instrument cluster. This display must be powered anytime
the shift lever is capable of being moved out of PARK (P).
This means that if your key is turned off, but not in LOCK,
there will be a small current drain on your battery which
could discharge your battery over a period of time. If you
need to leave your key in the ignition but not in LOCK for
an extended period, it is recommended that you
disconnect the battery cable from the battery to prevent
discharging your battery.
There are several different positions for your shift lever.PARK (P):This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
and move the shift lever to P (Park). SeeShifting
Into Park (Automatic Transmission) on
page 2-34. If you are pulling a trailer, seeTowing
a Trailer on page 4-48.
2-24

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in ON. If you cannot
shift out of PARK (P), ease pressure on the shift
lever by pushing the shift lever all the way into PARK (P)
as you maintain brake application. Then move the
shift lever into another gear. SeeShifting Out of Park
(Automatic Transmission) on page 2-36.
REVERSE (R):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-31.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, the
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while the engine is
running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
DRIVE (D):This position is for normal driving. If
provides the best fuel economy for your vehicle. If you
need more power for passing, and you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
2-25

THIRD, FOURTH AND FIFTH (3, 4 and 5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5) the same way
you do for SECOND (2). Slowly let up on the clutch pedal
as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to NEUTRAL.
NEUTRAL:Use this position when you start or idle
your engine.
REVERSE (R):To back up, press the clutch pedal. After
the vehicle stops, shift into REVERSE (R). Slowly let up
on the clutch pedal as you press the accelerator pedal. If
it is hard to shift, let the shift lever return to NEUTRAL
and release the clutch pedal. Then press the clutch again
and shift into REVERSE (R). Do not attempt to shift into
the fth gear position prior to shifting into REVERSE (R).
Your transmission has a lock out feature which prevents
a fth gear to reverse gear shift.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
Use REVERSE (R), along with the parking brake, for
parking your vehicle.Up-Shift Light
This light will show you
when to shift to the next
higher gear for best
fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions permit.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the shift light when you downshift.
If your vehicle has four-wheel drive and has a manual
transmission, disregard the shift light when the transfer
case is in four-wheel low.
For more information, seeUp-Shift Light on page 3-29.
2-27

Indicator lights in the buttons show you which setting you
are in. The indicator lights will come on briey when you
turn on the ignition and one will stay on the selected
setting. If the lights do not come on, you should take your
vehicle in for service. An indicator light will ash while
shifting. It will stay on when the shift is completed.
If for some reason the transfer case does not shift, it will
return to the last chosen setting.
Shifting from Two-Wheel High to
Four-Wheel High
Press and release the Four-Wheel High button. This
can be done at any speed, and the front axle will lock
automatically.
Shifting from Four-Wheel High to
Two-Wheel High
Press and release the Two-Wheel High button. This can
be done at any speed, and the front axle will unlock
automatically.
It is normal to hear and feel your vehicle’s transfer case
shift into Four-Wheel High. If you shift with the vehicle
stopped, the indicator light may still ash slowly. It
may be necessary to shift the transmission momentarily
into REVERSE (R) and DRIVE (D), for an automatic
transmission, or REVERSE (R) and FIRST (1) for
a manual transmission to have the light stop ashing.
Shifting from Two-Wheel High or
Four-Wheel High to Four-Wheel Low
To shift from Two-Wheel High or Four-Wheel High to
Four-Wheel Low, the vehicle must be stopped or moving
less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N) for an automatic transmission or the clutch
pedal pressed for a manual transmission. The preferred
method for shifting into Four-Wheel Low is to have your
vehicle moving 1 to 2 mph (1.6 to 3.2 km/h).
Press and release the Four-Wheel Low button. You
must wait for the Four-Wheel Low indicator light to stop
ashing and stay on before shifting the transmission
into gear or releasing the clutch pedal.
If the Four-Wheel Low button is pressed when your
vehicle is in gear and/or moving faster than 3 mph
(5 km/h), the four-wheel low indicator light will ash for
30 seconds and not complete the shift.
2-30

Shifting from Four-Wheel Low to
Two-Wheel High or Four-Wheel High
To shift from Four-Wheel Low to Two-Wheel High or
Four-Wheel High, your vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N) for an automatic transmission or the clutch
pedal pressed for a manual transmission. The preferred
method for shifting out of four-wheel low is to have your
vehicle moving 1 to 2 mph (1.6 to 3.2 km/h).
Press and release the Four-Wheel High or Two-Wheel
High button. You must wait for the Four-Wheel High
or Two-Wheel High indicator light to stop ashing and
stay on before shifting the transmission into gear or
releasing the clutch pedal.
If the Four-Wheel High or Two-Wheel High button is
pressed when your vehicle is in gear and/or moving
faster than 3 mph (5km/h), the Four-Wheel High or
Two Wheel High indicator light will ash for 30 seconds
but not complete the shift.
Shifting to NEUTRAL
