Section 2 Features and Controls
2-1 

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.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 is equipped with
a manual transmission, disregard the shift light when
the transfer case is in four-wheel low.
For more information, seeUp-Shift Light (Manual
Transmission) on page 3-28.

Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Do not shift down
more than one gear at a time when you
downshift.
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 most satisfaction 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 may
cause premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in four-wheel
drive for extended periods of time.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). 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 2-29.
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 brie y when
you turn on the ignition and one will stay on. 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.
