The front axle portion of the diagram on the indicator
will light up when you shift
into four-wheel drive. A
slight delay between shifting and the pattern's lighting is
normal. If the pattern does not light up, or if the front
axle lights
do not go out after you shift out of
four-wheel drive, have your dealer check your system.
Turn
the INT LIGHTS switch located to the right of
your headlamp switch to dim your transfer case
indicator light when your headlamps or parking lamps
are on. This
will also cause your instrument p.anel lights
to dim.
2HI: This setting is for driving in most street and
highway situat.ions. Your front axle
is not engaged in
two-wheel drive.
4HI: This setting engages your front axle to help
drive
your vehicle. Use 4H1 when you need extra
traction. such
as on snowy or icy roads. or in most
off-road situations.
N SET PARK BRAKE: Shift to this neutral setting
only when your vehicle needs to be towed.
4LO: This setting also engages your front axle to give
you extra traction and provides extra gear reduction.
YOLI may never need 4LO. It sends the maximum power
to all four wheels. You might choose 4L0 if you were
driving off-road
in sand, mud or deep snow and
climbing or descending steep hills.
You can shift from
2HI to 4H1 or from 4HI to 2HI while
the vehicle
is moving. Do not press the transfer case
shift lever button when shifting from
2HI to ;CHI or
from
4HI to 2HI.
To shift your transfer case into N SET PARK BRAKE:
1. Stop the vehicle and shift your transmission into
NEUTRAL
(N).
2. Set the parking brake. Your vehicle can roll unless
the brakes are applied.
3. Pull the transfer case shift lever into N SET
PARK BRAKE.

Page 87 of 410

To shift into or out of 4LO:
1. The vehicle must be moving less than 3 mph
(4.8 km/h) with the transmission in NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method
for shifting into or out of 4LO
is to have your vehicle moving I to 2 tnph (I .6 to
3.2 km/h).
2. Press the transfer case shift button and shift in one
continuous motion.
Don’t pause
in N SET PARK BRAKE as you shift into
or out of
4L0, or your gears could clash.
Remember that driving
in 4HI or 4LO may reduce fuel
economy. Also, driving in four-wheel drive on dry
pavement could cause your tires to wear faster and
make your transfer case harder to
shift and reduce
powertrain longevity.
Electronic Transfer Case (If Equipped)
If your four-wheel-drive
vehicle has the electronic
transfer case, the transfer
case switches are above
the radio controls.
Use these switches to shift into and out
of four-wheel
drive.
You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged
in
two-wheel drive. When this lamp is lit, it is about
one-half
as bright as the others.
4HI: This setting engages your front axle to help drive
your vehicle. Use
4HI when you need extra traction, such
as on snowy or icy roads. 01- in most off-road situations.

down with your right foot. Push down the parking brake
pedal with your left
foot. If the ignition is on, the brake
system warning light
will come on.
To

Shifting Into PARK (P) (Automatic
Transmission
Models Only)
It can be dangerous to get out of your vehicle if
the shift lever
is not fully in PARK (P) with the
parking brake firmly 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 won’t move, even when
you’re on fairly level ground, use the steps that
follow. If you have four-wheel drive with a manual
transfer case shift
lever and your transfer case is
in NEUTRAL (N), your vehicle will be free to roll,
even if your shift lever is in PARK (P). So, be sure
the transfer case is in
a drive gear -- not in
NEUTRAL
(N). If you’re pulling a trailer, see
“Towing a Trailer” in the Index.
Column Shift Lever
1. Hold the brake pedal down with your right foot and
set the parking brakc.
2. Move the shift lever into PARK (P) position like this:

3. If you have four-wheel drive with a manual transfer
case shift lever-. be sure the transfer case is in a drive
gear
-- not in NEUTRAL (N).
4. Turn the ignition key to LOCK.
5. Retnove the key and take it with you. If you can
leave your vehicle with the key, your vehicle is in
PARK (P).

Leaving Your Vehicle With the Engine
Running (Automatic Transmission
Models Only)
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move suddenlJ
if the shift lever
is not fully in PARK (P) with the
parking brake firmly set. If you have four-wheel
drive with
a manual transfer case shift lever and
your transfer case
is in NEUTRAL (N), your
vehicle will
be free to roll, even if your shift lever
is in
PARK (P). So be sure the transfer case is in a
drive gear
-- not in NEUTRAL (N). And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave
your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle
is in PARK (P) and yo~~r parking brake
is firmly set before you leave
it. After
you've moved the shift lever into the PARK
(P)
position, hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK (P)
without first pulling it toward you (or pressing the
button on
a console shift lever). If YOLI can, it means that
the shift lever wasn't fully locked
into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't 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 find it difficult to pull the shift
lever out
of PARK (P). This is called "torque lock." To
prevent torque lock, set the parking br'ke and then shift
into PARK
(P) properly before you leave the driver's seat.
To find out how, see "Shifting Into PARK (P)" in
the Index.
When
you are ready to drive, move the shift lever out of
PARK (P) kc$~w 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
~OLI can pull the shift lever out of PARK (P).

Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock.
YOLI have to fully apply your regular brake before you
can shift
from PARK (PI when the ignition is in the
RUN position. See "Automatic Transmission Operation"
in the Index.
If you cannot shift out of PARK (P)? ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want (you must
press the shift lever button
if you have the console
shift lever).
If you ever hold the brake pedal down but still can't
shift out
of PARK (P)? try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 3.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.
Parking Your Vehicle (Manual
Transmission Models Only)
Before you get out of your vehicle, turn off your engine,
put your- manual transmission in REVERSE (R) and
firmly apply the parking brake.
If you have four-wheel drive with it manual transfer case
shift lever, be sure your transfer case is in a drive gear.
Your vehicle could roll
if it isn't.
If you are parking on a hill. or if your vehicle is pulling
a trailer, see "Towing a Trailer" in the Index.

Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if
ever have to, here are some things to know.
Idling the engine with the air system control
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO -- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard.
l (See “Blizzard” in the Index.)
I-
It can be dangerous to get out of your vehicle if
the shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is running unless you have to.
If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
If you have four-wheel drive with a manual transfer case
shift lever and your transfer case is in NEUTRAL
(N),
your vehicle will be free to roll, even if your shift lever
is in
PARK (P). So, be sure the transfer case is in a drive
gear
-- not in NEUTRAL (N). Always set your parking
brake. Follow the proper steps
to be sure your vehicle
won’t move. See “Shifting Into
PARK (P)” in the Index.
If you’re pulling a trailer, see “Towing a Trailer” in
the Index.

Cruise Control (If Equipped)
With cruise control, you can
maintain
a speed of about
25 mph (40 krn/h) or more
without keeping your foot
on the accelerator. This
can
really help on long trips.
Cruise control
does not
work at speeds below about
25 rnph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut
off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will
shut off.
A CAUi ION:
I
Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don‘t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.

Setting Cruise Control
I
If you leave your cruise control switch on when
you’re not using cruise, you might hit a button
and
go into cruise when you don’t want to. You
could be startled and even lose control. Keep
the cruise control switch
OFF until you want to
use it.
1 - Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button
at the end
of the lever
and release
it.
4. TLlke your foot oft’ the
accelerator pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then
you apply the brake. This, of course, shuts off
the cruise control. But you don’t ne.ed to reset it.
Once. you’re going
about
25 mph (40 kmh) or nnore,
you can move the cruise
control switch from
ON
to R/A for about a half
a second.
You’ll go right back LIP to your chosen speed and
stay there.
Ren~ember. if you hold the switch at R/A longer than a
half a second, the vehicle will keep going faster until
you release the switch or apply the brake. You could be
startled and even lose control. So unless you want to go
faster. don‘t hold the switch at R/A.
