If your four-wheel
drive vehicle has the
electronic transfer
case, the transfer case
switches are on the
right side of your
instrument panel
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.
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,
or in most off-road situations.
4LO - This setting also engages your front axle to give you extra
traction. You may never need 4LO. It sends the maximum power to all
four wheels. You might choose
4LO if you were driving off-road in
sand, mud, deep snow and climbing or descending steep hills.
Amber indicator lights
in the switches show you which setting you are in.
The indicator lights will come on briefly 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. When shifting,
an indicator light will flash until the shift is
completed then remain solidly lit.
To shift from 2HI to 4HI - Press and release the 4HI switch. This can be
done at any speed, and the front axle will lock automatically.
To shift from 4HI to 2HI - Press and release the 2HI switch. This can be
done at any speed, and the front axle will unlock automatically.
To shift from 2H1, or 4HI to 4LO - The vehicle must be stopped or
moving less than
3 mph (4.8 km/h) with the transmission in NEUTRAL (N)
in vehicles equipped with an automatic transmission or the clutch pedal
depressed
in vehicles equipped with a manual transmission. The preferred
method for shifting into
4LO is to have your vehicle slowly moving 1 to 2
mph (1.6 to 3.2 km/h). Press and release the 4LO switch. You must wait for
the amber
4LO indicator light to stop flashing and go solid amber before
shifting your transmission into gear or releasing the clutch pedal.

Downloaded from www.Manualslib.com manuals search engine If the 4LO switch is pressed when your vehicle is in gear and/or moving, tht
amber 4LO indicator light will flash for
30 seconds and not complete the
shift unless your vehicle is below
3 mph (4.8 ludh) and the transmission is
in NEUTRAL (N) or the clutch pedal depressed.
On automatic transmission equipped vehicles: If your transfer case does not
shift into 4L0, your transmission indicator switch may require adjustment.
With your transmission in NEUTRAL (N), press and release the 4LO
switch. While the amber 4LO indicator light is flashing, shift your
transmission into PARK
(P).
Wait until the 4LO indicator light goes solid amber before shifting your
transmission into gear. This will get you into 4L0, but you should take your
vehicle in for service
so normal operation can be restored.
To shift from 4LO to 4HI - Your vehicle must be stopped or moving less
than
3 mph (4.8 kdh) with the transmission in NEUTRAL (N) or the clutcl
pedal depressed. The preferred method for shifting out of 4LO is to have
your vehicle slowly moving
1 to 2 mph (1.6 to 3.2 kdh). Press and release
the 4HI switch.
You must wait for the 4HI indicator light to stop flashing
and
go solid amber before shifting your transmission into gear or releasing
the clutch pedal.
If the 4HI switch is pressed when your vehicle
is in gear and/or moving, the
4HI indicator light will flash for
30 seconds but not complete the shift
unless the vehicle is below
3 mph (4.8 kmh) and the transmission is in
NEUTRAL (N) or the clutch pedal depressed.
On automatic transmission equipped vehicles: If your transfer case does not
shift into 4H1, your transmission indicator switch may require adjustment.
With your transmission in NEUTRAL (N), press and release the 4HI switch
While the 4HI indicator light is flashing, shift your transmission into PARK
(P). Wait until the 4HI indicator light goes solid amber before shifting your
transmission into gear. This will get you into 4H1, but you should take your
vehicle in for service
so normal operation can be restored.

Downloaded from www.Manualslib.com manuals search engine You will see this light flash for a few seconds when you turn your ignition
to
RUN or START. Then the light should go out. This means the system is
ready.
If the air bag readiness light doesn’t come on when you start your vehicle,
or stays on,
or comes on when you are driving, your air bag system may not
work properly. Have your vehicle serviced right away.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop
you. For good braking,
though, you need both parts working well.
If the warning light comes on, there could be a brake problem. Have your
brake system inspected right away.
This light should come on briefly
as you start the vehicle. If it doesn’t come
on then, have it fixed
so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully. You may notice that the pedal
is harder to push. Or, the pedal may
go closer to the floor. It may take longer to stop.
If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle” in
the Index.)

Downloaded from www.Manualslib.com manuals search engine The brake system warning light will also come on when you set your
parking brake, and it will stay on
if your parking brake doesn’t release fully.
If it stays
on after your parking brake is fully released, it means you have a
brake problem.
Anti-Lock Brake System Warning Light
ANTI-LOCK
With the anti-lock brake system, this light will come on when you start your
engine and may stay on for several seconds. That’s normal. If the light
doesn’t come on, have it fixed
so it will be ready to warn you if there is a
problem.
If the light stays on, or comes on when you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t on, you still have
brakes, but you don’t have anti-lock brakes.
If the regular brake system
warning light is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Indicator Lights
Indicator lights go on when you use your turn signals, change from low
beam headlights to high beams,
or when you use your hazard flashers. The
next few pages will also tell you about the indicator lights \
on your vehicle
and help you locate them.

SERVICE
ENGINE
SOON
The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top
of your instrument
panel.
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come on when the ignition is on, but the engine is
not running,
as a check to show you it is working. If it does not come on at
all, have it fixed right away. If it
stays on, or it comes on while you are
driving, the computer is indicating that
you have a problem. You should
take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after awhile\

the emission controls won’t work
as well, your fuel economy
won’t be as good and your engine may not run as smoothly.
This
could lead to costly repairs not covered by your warranty.
If Your Vehicle is Equipped with 08D 11
Certain vehicles are equipped with a new emission diagnostic sy\
stem. You
can
tell whether your vehicle has this system by reading your tune-up l\
abel
located under the hood. If the label says “OBD
11” on it, the following
instructions apply.
Malfunction Indicator Lamp (SERVICE ENGINE SOON Light)
Your vehicle is equipped with an onboard computer which monitors
operation
of the emission control system. This system is called OBD I1
(On-Board Diagnostics-Second Generation) and is intended
to assure that
emissions are at acceptable levels for the life
of the vehicle, helping to
produce a cleaner environment. The “SERVICE ENGINE
SOON’ light
comes on to indicate when service is required. Malfunctions oft\

2-72

Downloaded from www.Manualslib.com manuals search engine indicated by the system before any problem is apparent, which may prevent
more serious damage to your vehicle, This system is
also designed to assist
your service technician in correctly diagnosing any malfunction.
The
“SERVICE ENGINE SOON” light should come on, as a check to show
you it is working, when the ignition is on and the engine is not running. This
light will also come during
a malfunction in one of two ways:
Light on steady - indicates a system malfunction has been detected.
Drive the vehicle to the dealer for service at your first opportunity.
Light flashing - indicates a misfire has been detected which may
damage the emission control system. The damage may be reduced by
lowering the vehicle speed, reducing the amount of cargo being hauled
or trailered, avoiding hard acceleration, or by avoiding steep uphill
grades.
If these actions are effective, the light will stop flashing and
remain
on steady. Drive the vehicle to a dealer for service. If the light
continues to flash, stop
the vehicle. Wait for a steady light to come on,
then drive the vehicle to a dealer for service.
These following conditions also may cause the “SERVICE ENGINE
SOON’ light to come on:
Low Fuel/Out of Fuel - As the vehicle starts to run out of fuel the
“SERVICE ENGINE SOON” light may come on as a result of an engine
misfire. Filling your gasoline tank should correct this condition. Make sure
to install the gas cap fully. It will require a few driving trips to turn the light
off.
Poor Quality Fuel
- Be sure to fuel your vehicle with quality fuel. Your
engine may not run efficiently
on poor fuel. Poor fuel may cause stalling,
hesitation or misfire. These conditions may
go away when the engine is
warned-up. However, poor quality fuel may cause the “SERVICE ENGINE
SOON’ light to come on.
Have a dealer check the vehicle. If no problems are found, you may want to
change to another brand of fuel.
Driving Through Standing Water
- Driving your vehicle through puddles
of deep standing water may result in a temporary misfire condition. This
condition will usually correct itself shortly after the electric\
al system dries
out. It will require a few driving trips to turn the light off.

When your engine is
not running, but the ignition'is on (in the
RUN position), this
gage shows
your
battery's state of
charge in DC volts.
When the engine is running, the gage shows the condition of the charging
system. Readings between the low and high warning zones indicate the
normal operating range.
Readings in the low warning zone may occur when a large number of
electrical accessories are operating in the vehicle and the engine is left at an
idle for an extended period. This condition is normal since
the charging
system is not able to provide full power at engine idle.
As engine speeds are
increased, this condition should correct itself as higher engine speeds allow
the charging system to create maximum power.
You can only drive for
a short time with the reading in either warning zone.
If you must drive, turn
off all unnecessary accessories.
Readings in either warning zone indicate a possible problem in the electrical
system. Have the vehicle serviced as soon as possible.
Luggage Carrier (Option)
If you have a luggage carrier, you can load things on top of your vehicle.
The luggage carrier
has slats, side rails and
cross rails attached to
the roof to secure
cargo. The moveable
tie downs, attached to
the side rails, should
be used to secure loads to the luggage
carrier.

more information on vehicle capacity and loading,
see “Loading Your
Vehicle’’ in the Index.
To prevent damage or loss of cargo as you’re driving, check
now and then to
make sure the luggage carrier and cargo are still securely fastened.
Trailer Wiring Harness
Your vehicle will have a 5-wire and may have a 7-wire harness.
The light duty trailer wiring is a 5-wire harness assembly taped and bundled
at the left corner
of the vehicle. The harness has no connector, and you
should have
a qualified service person wire your harness for you.
The heavy duty trailer wiring is
a 7-wire harness assembly. It is stored
under the vehicle, along the passenger-side frame crossmember on
two-door vehicles and on the driver-side corner frame crossmember on
four-door vehicles. It has a 30-amp feed wire with an inline fuse located by
the junction block. See “Fuses and Circuit Breakers” in
the Index.
Both the 5-wire harness and the 7-wire harness have no connector and
should be wired by a qualified service person. Attach the harness to the
trailer, then tape or strap
it to your vehicle’s frame rail. Be sure you leave it
loose enough
so the wiring doesn’t bend or break, but not so loose that it
drags on the ground.
Store the harness
in its original place. Wrap the harness together and tie it
neatly
so it won’t be damaged.
