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 or
ACC. Once the key is turned from ON to LOCK,
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 your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to PARK (P) only when
your vehicle is stopped.
Manual Transmission
The shift lever should be in the NEUTRAL position
and the parking brake engaged. Hold the clutch
pedal 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 the 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.

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

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 Out of NEUTRAL
After towing your vehicle, you will have to shift
out of NEUTRAL in order to drive. To shift out
of NEUTRAL, do the following:
1. Set the parking brake and apply the regular
brake pedal.
2. Start a vehicle with an automatic transmission
in PARK (P). Use FIRST (1) for vehicles with
a manual transmission.
3. Shift the transmission to NEUTRAL (N), or
press the clutch pedal for vehicles with a
manual transmission.
4. Press the button for the desired transfer case
shift position (Two-Wheel High, Four-Wheel
High, or Four-Wheel Low).
5. After the transfer case has shifted out of
NEUTRAL, the indicator light will go out.
6. Release the parking brake.
7. Shift the transmission to the desired position.
Parking Brake
The parking brake
pedal is located to
the left of the regular
brake pedal, near
the driver’s door.
To set the parking brake, hold the regular
brake pedal down with your right foot. Push the
parking brake pedal down to its fully-applied
position with your left foot.
A chime will activate and the brake warning
light, located on the instrument panel, will ash
when the parking brake is applied and the vehicle
is moving at least 3 mph (5 km/h) for at least
three seconds. The chime will deactivate and the
light will turn off when the parking brake is set
and the vehicle is moving below 3 mph (5 km/h).
SeeBrake System Warning Light on page 189.
133

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.
137

Move the cruise lever from on to resume/
accelerate. Hold it there until you get up to the
speed desired, and then release the lever.
To increase your speed in very small amounts,
move the lever briey to resume/accelerate.
Reducing Speed While Using
Cruise Control

Press and hold the set button until you reach
the lower speed desired, then release it.
To slow down in very small amounts, briey
press the set button.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle
speed. When you take your foot off the pedal,
the vehicle will slow down to the cruise control
speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle speed, load, and the
steepness of the hills. When going up steep hills,
you might want to step on the accelerator
pedal to maintain the vehicle speed. When going
downhill, you might have to brake or shift to a
lower gear to keep the vehicle speed down.
Of course, applying the brake turns off the cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control lever to off.
Lightly tap or press the clutch, if you have a
manual transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.

As you are backing down the hill, put your left
hand on the steering wheel at the 12 o’clock
position. This way, you will be able to tell if the
wheels are straight and maneuver as you
back down. It is best that you back down the
hill with the wheels straight rather than in
the left or right direction. Turning the wheel
too far to the left or right will increase the
possibility of a rollover.
Here are some things youmust notdo if you stall,
or are about to stall, when going up a hill.
Never attempt to prevent a stall by shifting
into NEUTRAL (N), or pressing the clutch
if your vehicle has a manual transmission,
to rev-up the engine and regain forward
momentum. This will not work. Your vehicle
will roll backwards very quickly and you
could go out of control.
Instead, apply the regular brake to stop
the vehicle. Then apply the parking brake.
Shift to REVERSE (R), release the parking
brake, and slowly back straight down.
Never attempt to turn around if you are about
to stall when going up a hill. If the hill is
steep enough to stall your vehicle, it is steep
enough to cause you to roll over if you
turn around. If you cannot make it up the
hill, you must back straight down the hill.
Q:Suppose, after stalling, I try to back
down the hill and decide I just cannot
do it. What should I do?
A:Set the parking brake, put the automatic
transmission in PARK (P), or the manual
transmission in FIRST (1), and turn off
the engine. Leave the vehicle and go get
some help. Exit on the uphill side and
stay clear of the path the vehicle would
take if it rolled downhill.
269

Q:Are there some things I should not do
when driving down a hill?
A:Yes! These are important because if you
ignore them you could lose control and
have a serious accident.
When driving downhill, avoid turns that take
you across the incline of the hill. A hill that
is not too steep to drive down may be
too steep to drive across. You could roll
over if you do not drive straight down.
Never go downhill with the transmission in
NEUTRAL (N), or with the clutch pedal
pressed down with a manual transmission.
This is called “free-wheeling.” The brakes will
have to do all the work and could overheat
and fade.
Q:Am I likely to stall when going downhill?
A:It is much more likely to happen going
uphill. But if it happens going downhill,
here is what to do.
1. Stop your vehicle by applying the regular
brakes. Apply the parking brake.
2. Shift to PARK (P), or to NEUTRAL with the
manual transmission, and, while still braking,
restart the engine.
3. Shift back to a low gear, release the parking
brake, and drive straight down.
4. If the engine will not start, get out and
get help.
