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 brie y when
you start the engine just to let you know they
are 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 is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as 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 are a big help.

Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The vehicle’s odometer works together with the
Driver Information Center (DIC). A Trip A and
Trip B odometer can be set. See “Trip Information”
underDIC Operation and Displays on page 144.
The odometer mileage can be checked without the
vehicle running. Open the driver’s door and the
mileage will be displayed brie y.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty.
Do not operate the engine with the tachometer
in the shaded warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will be provided for several seconds to remind
people to buckle their safety belts. The driver safety
belt light will also be provided and stay on for
several seconds, then it will ash for several more.
You should buckle your seat belt.
This chime and light
will be repeated if the
driver remains
unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime
nor the light will be provided.

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your retailer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 130.
Charging System Light
The charging system
light will come on brie y
when you turn on the
ignition, and when
the engine is not
running, as a check to
show you it is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked by your retailer.
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.

Anti-Lock Brake System
Warning Light
Your vehicle may have
the Anti-Lock Brake
System (ABS).
This light will come on when your engine is
started and may stay on for several seconds.
That is normal.
If the light stays on, turn the ignition 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 after driving at a speed of at
least 13 mph (20 km/h), 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.
SeeBrake System Warning Light on page 134.
The ABS warning light will come on brie y
when you turn the ignition key to RUN. This is
normal. If the light does not come on then, have
it xed so it will be ready to warn you if there
is a problem.

Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
(2.0L Engine Only)
This light is located in
the center of the
instrument panel cluster.
For vehicles that have the Electronic Stability
Control (ESC) system or the Traction Control
System (TCS), this warning light should come on
brie y when the engine is started.If the warning light does not come on then, have it
xed so it will be ready to warn you if there is a
problem. This light, along with the appropriate
Driver Information Center (DIC) messages,
indicates when the ESC system and the TCS are
working or are disabled.
If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled.
Check your DIC messaging to determine
which feature(s) is no longer functioning and
whether it is because of the driver turning off the
feature(s), or the system may not be working
properly and your vehicle requires service. If the
TCS is disabled, wheel spin will not be limited.
If the ESC system is disabled, the system will not
aid in maintaining vehicle directional control. In
either case, adjust your driving accordingly.

If the light is on and ashing, the TCS or the
ESC system is actively working. Check the
DIC messaging for details to determine which
system is working. If the LOW TRACTION
message appears, the system is limiting wheel
spin. If the ESC ACTIVE message appears,
the system is aiding in maintaining vehicle
directional control.
SeeElectronic Stability Control on page 201and
Traction Control System (TCS) on page 199
for more information.
SeeDIC Warnings and Messages on page 147
for more information on the messages associated
with this light.Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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:Modi cations made to the engine,
transmission, 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. Modi cations 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. SeeAccessories
and Modifications on page 233.

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 mis re condition has
been detected. A mis re 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.
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 the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.If the light continues to ash, 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 ashing, follow the
previous steps, and see your retailer for service as
soon as possible.
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. SeeFilling the Tank on page 238.
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.
SeeGasoline Octane on page 235. 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, mis ring, 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 one or more of these conditions,
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, your retailer can check the vehicle.
Your retailer has the proper test equipment
and diagnostic tools to x any mechanical or
electrical problems that may have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your retailer
can prepare the vehicle for inspection.

Oil Pressure Light
If you have a low engine
oil pressure problem,
this light will stay on after
you start your engine,
or come on when you
are driving.
This indicates that your engine is not receiving
enough oil.
The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
show you it is working, but the light will go
out when you turn the ignition to START.
If it does not come on with the ignition on, you
may have a problem with the fuse or bulb.
Have it xed right away.
If you are idling at a stop sign, the light may
blink on and then off.
If you make a hard stop, the light may come
on for a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
