Traction Control System (TCS)
Warning Light
,
TRAC
OFF
United States Canada
This warning light should come on briefly when the
engine
is started.
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 it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your ariving accordingiy. The
traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the TC button
located on the center console, the warning light will
come on and stay on. To turn the system back
on, press the button again. The warning light should
go
off. See Traction Control System (TCS) on
page 4-8 for more information.
If there’s a brake system problem that is specifically
related to traction control, the traction control
system will turn
off and the warning light will come
on.
If your brakes begin to overheat, the traction
control system will turn
off and the warning light will
come on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the 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.

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 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.
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 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 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 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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
* Avoiding hard accelerations.
b Avoiding steep uphill grades.
If you are 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.
Find a safe place to park your vehicle. Turn the key off,
wait at least
10 seconds and restad 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 also 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
Filhg 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.
Are you low on fuel?
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. See
Filling Your Tank on page 5-7. 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
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.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
UI-I~ iuii ia~k ui iile pruper iuei iu iurrl iile iiyili uii.
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.

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, see your dealer or qualified service
center to prepare the vehicle for inspection.
Oil Pressure Light
If you have a problem with
your
oil, this light may stay
on after you start your
engine, or come on when
you are driving.
A warning chime and the DIC message
LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be
low on oil, or could have some other oil problem. Have
it fixed right away.
The oil light could also come on briefly 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 about five seconds after you turn
the ignition to START.
If it doesn’t come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it fixed right away.

Fuel Gage Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
United States Canada
When the ignition is on, your fuel gage tells you about
how much fuel you have left.
When you have less than
3.5 gallons (13.2 L) of fuel
remaining, the
DIC message LOW FUEL will be
displayed and a chime will sound. You need to get more
fuel right away.
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
fill the tank.
The gage moves a little when you turn a corner or
speed up.
The tank is not necessarily empty when the gage
reads empty. There
is a reserve of about
1.5 gallons (5.6 L) in the tank. You should still get
more fuel as
soon as possible.

CHECK OIL LEVEL - 5: If you ever see the CHECK
OIL LEVEL message, it indicates that the engine oil level
is
1 to 1 1/2 quarts (0.9 L to 1.4 L) low. The message
will appear only
if the engine is running and it has been
at least eight minutes since the engine was last
running. If the message appears, check the oil dipstick
level.
If it reads low, your oil level should be brought
up
to the proper level. See Engine Oil on page 5-15.
After bringing the oil to the proper level, the ignition must
be
off for eight minutes to allow the majority of oil to
drain into the oil pan.
SERV STABILITY SYS
- 26: If you ever see the SERV
STABILITY SYS message, it means there may be a
problem with your stability enhancement system.
If you
see this message,
try to reset the system (stop; turn
off the engine; then start the engine again). If the SERV
STABILITY SYS message still comes on, it means
there is a problem. You should see your dealer
for service. Reduce your speed and drive accordingly. STABILITY ACTIVE
- 25: You may
see the STABILITY
ACTIVE message on the Driver Information Center
(DIC). It means that an advanced, computer-controlled
system has come on to help your vehicle continue
to go in the direction in which you’re steering. This
stability enhancement system activates when the
computer senses that your vehicle is just starting to
spin, as
it might if you hit a patch of ice or other slippery
spot on the road. When the system is on, you may
hear a noise or feel a vibration in the brake pedal. This is normal.
When the STABILITY ACTIVE message is on, you
should continue to steer in the direction you want to
The system is designed to help you in bad weather
or other difficult driving situations by making the most of
whatever road conditions will permit.
If the STABILITY
ACTIVE message comes
on, you’ll know that something
has caused your vehicle to start to spin,
so you should
consider slowing down.
