Downloaded from www.Manualslib.com manuals search engine Turn Signal and Lane Change Indicator
The turn signal has
two upward (for
Right) and two
downward (for Left)
positions. These
positions allow you
to
signal a turn or a lane
change.
To signal a turn, move the lever all the way up or down. When the turn is
finished, the lever will return automatically.
es
A green arrow on the
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 installed, 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 working.

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.

Downloaded from www.Manualslib.com manuals search engine Normal operating range shows your engine speed during normal driving
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.
I 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 can 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.

When the key is turned to RUN or START, a tone will come on for about
eight seconds
to remind people to fasten their safety belts, unless the
driver’s safety belt
is already buckled. The safety belt light will also come
on and stay on for about 20 seconds, then it will flash for about 55 seconds.
If the driver’s belt is already buckled, neither the tone nor the light will
come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument panel, which shows
AIR
BAG. The system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical problem.
The
system check includes the air bag sensors and module, the wiring and the
diagnostic module. For more information on the air bag system, see “Air
Bag” in the Index.

Downloaded from www.Manualslib.com manuals search engine 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.
Malfunction Indicator Lamp (SERVICE ENGINE SOON
Light)
The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top of your instrument
panel.
SERVICE
ENGINE
SOON
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 OBD I1
Certain vehicles with 4.3 liter engines are equipped with a new emission
diagnostic system. You can tell whether your vehicle has this system
by
reading your tune-up label located under the hood. If the label says “OBD
11” on it, the following instructions apply.

Downloaded from www.Manualslib.com manuals search engine 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 often will be
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:
0
0
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 FueVOut 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 electrical system dries
out. It will require a few driving trips to turn the light off.
