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 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 135.
If you are pulling a trailer, seeTowing
a Trailer on page 306.
124

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 137.
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 290.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 your
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.
125

Here is how to operate your manual transmission:
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal
as you slowly press down on the accelerator pedal.
You can shift into FIRST (1) when you are going
less than 20 mph (30 km/h). If you have come to a
complete stop and it is hard to shift into FIRST (1),
put the shift lever in NEUTRAL and let up on the
clutch. Then press the clutch pedal back down and
shift into FIRST (1).
SECOND (2):Press the clutch pedal as you
let up on the accelerator pedal and shift into
SECOND (2). Then, slowly let up on the clutch
pedal as you press the accelerator pedal.
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 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.
Use REVERSE (R), along with the parking brake,
for parking your vehicle.
127

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 133.
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.
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.
130

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.
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).
131

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.
SeeRecreational Vehicle Towing on page 300
for 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.
7. Turn the engine off by turning the key to ACC.
8. Place the transmission shift lever in PARK (P),
or FIRST (1) for vehicles that have a manual
transmission.
9. Turn the ignition to LOCK.
132

Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be 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. 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, use the steps that follow.
If you are pulling a trailer, seeTowing
a Trailer on page 306.
1. Hold the brake pedal down with your right
foot and set the parking brake.
SeeParking Brake on page 133for more
information.
{CAUTION:
If you have four-wheel drive, your vehicle
will be free to roll — even if your shift
lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the
transfer case is in a drive gear, two-wheel
high (2H) or four-wheel high (4H) or
four-wheel low (4L) — not in NEUTRAL.
2. Move the shift lever into PARK (P) by
pulling the lever toward you and moving
it up as far as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you.
If you can leave your vehicle with the
key, your vehicle is in PARK (P).
135

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever
into PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever away
from PARK (P) without rst pulling it toward you.
If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much
force on the parking pawl in the transmission.
You may nd it difficult to pull the shift lever out
of PARK (P). This is called torque lock. To prevent
torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into
Park (P) (Automatic Transmission) on page 135.
When you are ready to drive, move the shift
lever out of PARK (P) before you release the
parking brake.
If torque lock does occur, you may need to
have another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, so you can pull the shift
lever out of PARK (P).
136

Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is in the LOCK
position. In addition, you have to fully apply the
regular brakes before you can shift from PARK (P)
when the ignition is in ON. SeeAutomatic
Transmission Operation on page 124.
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
the gear you want.
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Turn the key to ACC. There is no shift
interlock in this key position.
2. Apply and hold the brake until the end of
Step 4.3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear
you want.
5. Have the system xed as soon as you can.
Parking Your Vehicle
(Manual Transmission)
Your vehicle has a manual transmission.
Before you get out of your vehicle, move the
shift lever into REVERSE (R), and rmly apply
the parking brake. Once the shift lever has
been placed into REVERSE (R) with the clutch
pedal pressed in, turn the ignition key to LOCK,
remove the key and release the clutch.
If you are parking on a hill, or if your vehicle is
pulling a trailer, seeTowing a Trailer on page 306.

If the display reads CAL, the compass needs
to be calibrated. For more information, see
“Compass Calibration” following.
To adjust between Fahrenheit and Celsius:
1. Press and hold the on/off button for
approximately four seconds until either
a ashing F or C appears.
2. Press the button again to change the display
to the desired unit of measurement. After
approximately four seconds of inactivity,
the new unit will be locked in and the
compass/temperature display will return.
If an abnormal temperature reading is displayed
for an extended period of time, see your
dealer/retailer. Under certain circumstances, a
delay in updating the temperature is normal.
Automatic Dimming Mirror Operation
The automatic dimming mirror comes on each time
the ignition is turned to start. To turn the automatic
dimming feature off or back on, press the on/off
button. The indicator light on the mirror is lit when
the automatic dimming feature is on.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately ve seconds, the display
does not show a compass heading, N for
North, for example, there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note
pad holder, or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.
In order to calibrate, CAL must be displayed
in the mirror compass windows. If CAL is
not displayed, push the on/off button for
approximately 12 seconds or until CAL is
displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until
the display reads a direction.
