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 briey 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
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.
The ERROR message is displayed on the odometer
indicating that the speedometer reading is approximately
10 percent above the actual speed. The SERVICE
VEHICLE SOON light will also come on. Press the trip
odometer button to return to the odometer/trip mode.
This message will appear every 10 minutes. If this
occurs, see your dealer for service.
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
Your trip odometer is located on the instrument panel
and shows how far your vehicle has been driven
since the trip odometer was last reset. To reset the trip
odometer to zero, press and hold the trip/reset button
on the speedometer for about two seconds.
Tachometer
The tachometer shows your engine speed in revolutions
per minute (rpm).

may not be working properly. The airbags in
your vehicle may not inate in a crash, or they

avoid injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start your

Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the red BRAKE light is not on, you still
have brakes, but you do not have anti-lock brakes. See
Brake System Warning Light on page 3-28.If the light stays on, turn the ignition to OFF. If the light
comes on when you are 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 are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-28.

Traction Control System (TCS)
Warning Light
Your vehicle may have a
traction control system
warning light. The traction
control system warning
light may come on for the
following reasons:
For vehicles equipped with the traction control
system and front-wheel drive, this light will come on
and stay on if you turn the system off by pressing
the traction control button located on the instrument
panel above the audio system. To turn the system
back on, press the button again. The warning
light should go off. SeeTraction Control
System (TCS) on page 4-8for more information.
For vehicles equipped with all-wheel-drive, this light
will come on and stay on when the all-wheel-drive
system is unable to protect for overheating
under extended heavy all-wheel-drive usage.
If there is an engine-related and brake system
problem that is specically related to traction control,
the traction control system will turn off and the
warning light will come on.If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Low Traction Light
If your vehicle has the
Traction Control
System (TCS) and has
front-wheel-drive, this
light will come on when
the system is limiting
wheel spin.
If your vehicle has all-wheel-drive, this light will come on
when the all-wheel-drive system is protecting itself
from overheating due to extended heavy all wheel drive
usage.
You may feel or hear the system working, but this is
normal. The roads may be slippery if this light comes on.
Adjust your driving accordingly.
The light will stay on for a few seconds after the system
stops limiting wheel spin. This light should also come
on for a few seconds when you start your vehicle.
If it does not, have your vehicle serviced.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating on
page 5-24for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-24.
Your vehicle could be damaged, and it might not be
covered by your warranty. Never drive with the
engine coolant temperature warning light on.
This light will also come on when starting your vehicle.
If it doesn’t, have your vehicle serviced.
This light will ash when the transaxle has overheated.
See “Transaxle Overheating”, underAutomatic
Transaxle Operation on page 2-19, for more information.
Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine.
If the indicator needle moves into the shaded area, the
engine is too hot. A temperature indicator light will
turn on.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

Malfunction Indicator Lamp
Check Engine Light
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 check engine 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 awhile, 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.Notice:Modications 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.
Modications to these systems could lead to costly
repairs not covered by 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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
