Speedometer
Your speedometer lets YOLI see your speed in both miles
per hour (mph) and kilometers per hour
(ktdh). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used
in Canada).
YOLI may wonder what happens if YOLK vehicle needs a
new odometer installed. Laws vary as to the procedure
that must be followed,
so check with your 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.
nip Odometer
The trip odometer can tell
YOLI how far your
vehicle has been driven
since you last set the trip
odometer
to zero.
To reset the trip odometer,
fully press the reset button
located near the trip odometer readout.
The odometer
can show either total miles or trip miles
by using the push control
in the cluster.

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
ao repam can be costly -- and even aangerous.
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.

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.
BRAKE

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”

when you start your engine and may stay on for several
seconds. That’s normal.
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. The

Malfunction Indicator Lamp (Service Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the
-
SERVICE
ENGINE SOON
fuel, ignition and emission
control systems.
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.
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:
0
0
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.
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.

If the Light Is Flashing Are you low on fuel‘?
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
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 “If
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 c0rrecte.d 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
s~nall 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
“FLE~”
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.

Oil Pressure Gage
The oil pressure gage shows the engine oil
pressure in psi (pounds
per square inch) when the engine is running. Canadian
vehicles indicate pressure
Oil pressure may vary with engine speed, outside
temperature and oil viscosity,
but readings above
the
lowpressure 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.
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.
