Removing the Tailgate
Follow these steps if you want to remove the tailgate:
1. With the tailgate fully open, lift up slightly on the
entire tailgate assembly.
Remove the retaining
cables from both sides of
the tailgate by pulling the
clips away from the bolt
heads while pushing the
cable bracket forward.
When the larger part of the
hole on the bracket is over
the bolt, slide the bracket
off of the bolt.
2. With the tailgate partially down, lift up on the
passenger’s side and pull the tailgate toward
you, then move the tailgate to the right to release
the driver’s side. You can then remove the
entire tailgate assembly.
Reverse the procedure to reinstall the tailgate. Make
sure it is secure.To partially lower the tailgate do the following:
1. With the tailgate fully open, lift up slightly on the
entire tailgate assembly.
2. Remove the retaining
cable from the
passenger side of the
tailgate by pulling the
clip away from the bolt
head while pushing the
cable bracket forward.
When the larger part of the hole on the bracket is
over the bolt, slide the bracket off of the bolt.
3. Slide the lower end tting onto the top bolt. The
tailgate will now stay in the partially opened
position.
4. Repeat steps 2 and 3 for the driver side.
If you would like to close the tailgate, the bracket
cannot be in the partially opened position and must be
anchored on the bottom bolt, using the top position
on the bracket.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops with
new linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-44for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
With the key in the ignition
switch, you can turn to four
different positions.
To shift out of PARK (P), the ignition must be in
ON/RUN and the regular brake pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
none of this works, then your vehicle needs service.
(A) LOCK/OFF:This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It locks the steering wheel on manual
transmission vehicles when the key is removed. It is a
theft-deterrent feature. You will only be able to remove
your key when the ignition is turned to LOCK/OFF.
2-19

If you have an automatic transmission, the ignition
switch cannot be turned to LOCK/OFF unless the shift
lever is in PARK (P).
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of this
works, then your vehicle needs service.
(B) ACC/ACCESSORY:This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. On automatic
transmission vehicles, this position unlocks the ignition.
On manual transmission vehicles, it unlocks the ignition
and steering wheel. Use this position if your vehicle must
be pushed or towed.
(C) ON/RUN:This is the position that the switch returns
to after you start your engine and release the switch.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON/RUN to operate the electrical accessories and
to display some instrument panel cluster warning and
indicator lights. The transmission is also unlocked in
this position on automatic transmission vehicles.
The battery could be drained if you leave the key in the
ACC/ACCESORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
When the engine is not running, ACC/ACCESSORY
and ON/RUN allows you to operate the electrical
accessories, such as the radio or items plugged into
the accessory power outlets.
A warning tone will sound if you open the driver’s door
when the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
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.
2-20

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 your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your 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 your vehicle will not move, even when you
are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into PARK (P)
(Automatic Transmission) on page 2-34.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 4-44.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 (P) (Automatic
Transmission) on page 2-36.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your 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 4-30.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only.
2-24

{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, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your 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.Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-9.
THIRD (3):This position is also used for normal driving.
However, it reduces vehicle speed more than DRIVE (D)
without using your brakes. You might choose THIRD (3)
instead of DRIVE (D) when driving on hilly, winding
roads, when towing a trailer, so there is less shifting
between gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your brakes.
You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your brakes
off and on.
FIRST (1):This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
2-25

Four-Wheel Drive
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction. To get the best performance out of four-wheel
drive, you must be familiar with its operation. Read the
part that follows before using four-wheel drive. You
should use two-wheel-drive high for most normal driving
conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time can
cause premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in Four-Wheel
Drive for extended periods of time.
Notice:If your vehicle has four-wheel drive and the
compact spare tire is installed on your vehicle, do
not drive in four-wheel drive until you can have
your at tire repaired and/or replaced. You could
damage your vehicle, and the repair costs would not
be covered by your warranty. Never use four-wheel
drive when the compact spare tire is installed
on your vehicle.The transfer case buttons are located to the right of the
steering wheel on the instrument panel.

Use these buttons to shift into and out of four-wheel
drive. You can choose from the following:
2
m(Two-Wheel High):This setting is for driving in
most street and highway situations. Your front axle is not
engaged in two-wheel drive.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P), or if you have a
manual transmission, even if you are in gear.
You or someone else could be seriously
injured. Be sure to set the parking brake
before placing the transfer case in NEUTRAL.
SeeParking Brake on page 2-32.
N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.4
m(Four-Wheel High):This setting engages your
front axle to help drive your vehicle. Use four-wheel high
when you need extra traction, such as on snowy or
icy roads, or in most off-road situations.
4
n(Four-Wheel Low):This setting also engages
your front axle to give you extra traction. It sends
the maximum power to all four wheels. You might
choose four-wheel low if you were driving off-road in
sand, mud, or deep snow and while climbing or
descending steep hills.
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.
2-29

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
Use NEUTRAL when you plan to tow your vehicle. See
Recreational Vehicle Towing on page 4-38for towing
instructions. To shift the transfer case into NEUTRAL do
the following:
1. Set the parking brake.
2. Start the vehicle.
3. Press the regular brake pedal and shift the
transmission in NEUTRAL (N), or press in the clutch
for vehicles with a manual transmission.
4. Shift the transfer case to Two-Wheel High.
5. Press and hold the Two-Wheel High and
Four-Wheel Low buttons at the same time for
10 seconds. The NEUTRAL (N) light will come on
when the transfer case shift to NEUTRAL (N)
is complete.
6. Press and hold the regular brake pedal and shift
the transmission to REVERSE (R) for one second,
then shift the transmission to DRIVE (D) for one
second, or FIRST (1) for vehicles with manual
transmissions, and let out the clutch to insure the
transfer case is in NEUTRAL. If the vehicle is not in
NEUTRAL, repeat this procedure starting at Step 3.
