headlights or parking lights are on. This will also cause your instrument
panel lights to dim.
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 mos
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. 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, or deep snow and climbing or descending
steep hills.
You can shift from 2HI to 4HI or from 4HI to 2HI while the vehicle is
moving.
Do not press the transfer case shift lever button when shifting fron
2HI to 4HI or from 4HI to 2HI. Your front axle will engage faster
if you
take your foot off
of the accelerator for a few seconds after you shift.
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.
To shift into or out
of 4LO:
1. The vehicle must be stopped or moving less than 3 mph (4.8 kdh)
with the transmission in NEUTRAL
(N) for an automatic transmission
or the clutch pedal depressed with a manual transmission.
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 wea
faster and make your transfer case harder to shift and reduce powertrain
longevity.

instrument panel will
flash
in the direction
of the turn or lane
change.
To signal a lane change, just raise or lower the lever until the green arrow
starts to flash. Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane change, if the arrows don’t flash but just stay
on, a signal bulb may be burned out and other drivers won’t see your turn
signal.
If a bulb is burned out, replace it to help avoid an accident. If the green
arrows don’t go on at all when
you signal a turn, check the fuse (see “Fuses”
in the Index) and for burned-out bulbs.
If you have a trailer towing option with added wiring for the trailer lights, a
different turn signal flasher is used. With this flasher instal\
led, the signal
indicator will flash even if
a turn signal bulb is burned out. Check the front
and rear turn signal lights regularly to make sure they are w\
orking.
Operation of Lighting System
Although your vehicle’s lighting system (headlamps, parking lamps, fog
lamps, side marker lamps and taillamps) meets all applicable federal
lighting requirements, certain states and provinces may apply their own
lighting regulations that may require special attention before you operate
these lamps.
For example, some jurisdictions may require that you operate your fog
lamps only when your lower beam headlamps are also on,
or that headlamps
be turned on whenever you must use your windshield wipers. In \
addition,
most jurisdictions prohibit driving solely with parking lamps, especially at
dawn or dusk. It is recommended that you check with your own state or
provincial highway authority for applicable lighting regulations.

wipers start, then let
go. The wipers will stop after one wipe. If you want
more wipes, hold the band on MIST longer.
You can set the wiper speed for a long or short delay between wipes.
This
can be very useful in light rain or snow. Turn the band to choose the delay
time. The closer to
LO, the shorter the delay.
For steady wiping at low speed, turn the band away from you to the
LO
position. For high speed wiping, turn the band further, to HI. To stop the
wipers
, move the band to the off symbol.
Remember that worn or damaged wiper blades may prevent you from
seeing well enough to drive safely. To avoid damage, be sure to clear ice
and snow from the wiper blades before using them. If they’re frozen to the
windshield, carefully loosen or thaw them.
If your blades do become worn
or damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. The windshield wiper motor is
protected
from overload by a circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper
will stop until the motor cools.
Although the circuit is protected from electrical overload, overload due to
heavy snow, etc. may cause wiper linkage damage. Always clear ice and
heavy snow from the windshield before using your windshield wipers.
Windshield Washer
At the top of the
multifunction lever
there’s a paddle
marked with the
windshield washer
symbol and PUSH. To
spray washer fluid on
the windshield, push
the paddle.
The wipers will clear the window and then either stop or return to your
preset speed.
Driving without washer fluid can be dangerous. A bad mud splash can block
your vision. You could hit another vehicle or go
off the road. Check your
washer fluid level often.

conditions.
For example, when the needle points to 2, it means the engine is
running at 2,000 revolutions per minute (rpm). The tachometer needle will
vary all the time that the engine is running.
The red warning range tells you that your engine speed is reaching its upper
limits. Don’t drive very long with the tachometer in the red warning range.
If you have a manual transmission, shift to a higher gear as
soon as possible.
If you have an automatic transmission, lift your foot
off of the accelerator
pedal. If you drive for very long with the tachometer in the red danger
range, engine damage will result.
NOTICE:
Do not operate the engine with the tachometer in the red range,
or engine damage will occur.
The red danger range tells you that your engine speed is at its upper limits.
You should immediately shift to a higher gear, or lift your foot
off of the
accelerator pedal. If you drive for very long with the tachometer in the red
danger range, engine damage will result.
Warning Lights and Indicators
This part describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong before it
becomes serious enough to cause an expensive repair or replacement.
Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you start the engine just to let
you know they’re working. If you are familiar with this section, you should
not be alarmed when this happens.
Gages caa indicate when there may be or is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells you what
to do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re a big help.

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\

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

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.
