BRAKE
~~~
United States
Canada
This light should come on briefly when you turn the
ignition key to
ON. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a problem.
When the ignition is on, the brake system warning
light will also come on when you set your parking brake.
The light will stay on
if your parking brake doesn’t
release fully.
If it stays on after your parking brake is
fully released, it means you have a brake 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 on page 4-32.
Your brake system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident.
If the light is still
on after you’ve pulled
off the road and stopped
carefully, have the vehicle towed for service.

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
so it will be ready to warn you if there is a problem.
Enhanced Traction System
Warning Light
TRAC
OFF
If your vehicle has the
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.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.

more information.
0 If the traction control system is affected by an
engine-related problem, the system will turn
off and
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
LOW
TRAC
If your vehicle has the
Enhanced Traction System
(ET§), this light
will
come on when the system
is limiting wheel spin.
Slippery road conditions may exist
if the Enhanced
Traction System active light comes
on, so adjust your
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.
3-32

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,
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
in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection
if the SERVICE
ENGINE SOON 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.
3-33

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 and you will hear
a chime 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 fixed immediately.
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 the engine is running.
If
it doesn’t come on with the ignition on, you may have a
problem with the bulb. Have it fixed right away. 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.
Notice: Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Low Oil Level Light
LOW
OIL
If your vehicle is equipped
with a
3400 V6 engine,
then you will have a
LOW
OIL light in your
instrument panel cluster.
This light will come on briefly when you start your
vehicle.
If the light stays on after starting your vehicle, or comes
on and chimes while you are driving, your engine oil
level should be checked.
Prior to checking the oil level, be sure your vehicle has
been shut
off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring it
to the proper level. See Engine Oil on page 5-15.
A false LOW OIL light may be generated when parking
on steep grades.
The oil level monitoring system only checks oil level
during the brief period between when the key is on and
the engine is cranking.
It does not monitor engine oil level
when the engine is running. Additionally, an oil
level check is only performed
if the engine has
been turned
off for a considerable period of time
allowing the
oil normally in circulation to drain back into
the oil pan.
CHANGE
OIL
The CHANGE OIL light
should come on briefly as
a bulb check when you start the engine. If the light
doesn’t come on, have it
serviced.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
To reset the CHANGE
OIL light, see Engine oil On
page
