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.

Speedometer and Odometer Tachometer
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).
Your vehicle has a tamper resistant odometer. The
digital odometer will read 999,999
if someone tries to
turn it back.
You may wonder what happens
if your vehicle needs a
new odometer installed. If the new one 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.
Trip Odometer
The trip odometer can tell you how far you have driven
since you last reset it. The
tachometer shows your engine speed in revolutions
per minute
(rpm).
Notice: Do not operate the engine with the
tachometer in the red area,
or engine damage
may occur.
The reset button is located below the tachometer. To
reset the trip odometer
to zero, press and hold briefly the
ribbed side of the button while the trip odometer is
displayed.
Also, by pressing this button for less than one
second you can toggle between the odometer and the
trip odometer.

so it will
be ready to warn you
if there is a problem.
Charging System Light
The charging system light
will come on when you
turn on the ignition, but the
II engine is not running, as
a check to show you
it
is working.
When the engine is running, the light should go out.
If it stays on, or comes on while you are driving and you
hear a chime, you may have a problem with the
electrical charging system. It could indicate that you have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while
this light is on could drain your battery. If
you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.

vehicle has this feature
this light comes on
when you need to shift to
the next higher gear.
See
Manual Transaxle
Operation on page
2-27.
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.
3-26

Anti-Lock Brake System
Warning Light
If your vehicle has the
anti-lock brake system, the
light will come on when
your engine is started and
may stay on for several
seconds. That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon
as possible and turn the ignition
off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while 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 on page 3-26 earlier in this
section.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key
to ON. This is
normal.
If the light doesn’t come on then, have it fixed

Enhanced Traction System
(ETS), this warning light
should come on briefly as
you start the engine.
If the warning light doesn’t come on then, have it fixed
so it will be ready to warn you if there’s a problem.
If the warning light stays on, or comes on when you’re
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.

the warning light will come on.
0 If the vehicle is driven on an extremely rough road,
the warning light may come on momentarily but will
go
off again when the vehicle leaves the rough
surface.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system is turned on and the parking brake is fully
released, your vehicle needs service.
Enhanced Traction System
Active Light

driving accordingly.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes on briefly when you turn the ignition key to
ON. If
the light doesn’t come on then, have
it fixed so it will be
there
to tell you when the system is active.

Malfunction Indicator Lamp
Service Engine Soon Light
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission control systems.
This system is called OBD
II (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. This
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
smoothly. This could lead to costly repairs that may not be covered by your warramty.
be 85 gcod and yaur engine may not run as
Notice: Modifications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of
the original tires with
other than those
of the same Tire Performance
Criteria
(TPC) can affect your vehicle’s emission
controls and may cause
this light to come on.
Modifications to these systems could lead to costly
repairs not covered &y your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
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:
e
e
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 may be 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.
3-31

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being h%uled 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. Find a safe place to park your vehicle.
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 recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See
Filling Your Tank on page 5-7. The
diagnostic system can determine
if the fuel cap has
been left
off or improperly installed. A loose or missing
fuel cap will allow fuel
to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light
off.
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.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. 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.
