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.
An 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 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 flash
at twice the normal rate, a signal bulb may be burned
out and other drivers may not see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If.the arrows don’t go on at all when
you
signal a turn, check for burned-out bulbs and a blown
fuse (see “Fuses and Circuit Breakers” in the Index).
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.

Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
You may wonder what happens if your vehicle needs a
new odometer installed. Laws vary as to the procedure
that must be followed,
so check with yo~~r state or
provincial vehicle registration office.
But generally, if
the new odometer can be set to the mileage total of the
old odometer, then
it must be. But if it can’t, then it’s set
at zero,
and a label must be put on the driver’s door to
show the old mileage reading
when the new odometer
was installed.

Downloaded from www.Manualslib.com manuals search engine Warning Lights, Gages 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.
Safety Belt Reminder Light
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.

Downloaded from www.Manualslib.com manuals search engine 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 sensor, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information
on the air bag system, see “Air
Bag” in
the Index.
AIR
BAG
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.
Charging System Light
This light should come on
briefly when you turn on the
ignition, before starting the
engine, as a check to show
you
it is working.
After the engine starts, the light should go out. If it stays
on or comes on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the alternator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it
helps
to turn off all your accessories, such as the radio
and air conditioner.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Service
Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
SERVICE
ENGINE SOON
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 that there is a problem and 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.
I NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel economy may not be
as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition
is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light
will also come on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage
the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service
is required.
0 Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing Are you low on fuel?
The following may prevent more serious damage
to
your vehicle:
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as
it is possible.
If the light stops flashing and remains on steady, see
--IT
the Light Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains on steady, see “If the Light
Is On
Steady” following. If the light is still flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering
the following:
Did
you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when
the electrical system
dries
out. A few driving trips should turn the light off. As
your engine starts
to run out of fuel, your engine may
not run
as efficiently as designed since small amounts of
air are sucked
into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off.
Have you recently changed brands
of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling
on acceleration. (These conditions may go
away once the engine is warmed up.) This will be
detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
The oil pressure gage
pressure
in psi (pounds
shows
the engine oil
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
OIL 93
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low
oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
A C -1TION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You
or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
