If you must drive a short distance with the voltmeter
reading
in a warning zone, turn off all your accessories,
including
your air conditioning and audio system.
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.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you
turn the
ignition key to
RUN. If it
doesn’t come
on then,
have it fixed
so it will be
ready to
warn you if there’s
a 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”
in the Index.)
I A CAUTION:
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.
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 haye 3 bg,&e problem.

Anti-Lock Brake System Warning Light
ABS
INOP
With the anti-lock brake system, this light will come
on when you start your
engine and
it will stay
on for three seconds.
That’s normal.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. Or, if the light comes on and stays 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
light is on and the regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti-lock brakes. Adjust your driving accordingly.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning Light
(Option)
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 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
driving accordingly.
The traction control system warning light will come on
if
you turn the system off by pressing the TCS button
located in front
of the 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” in the Index for
more information.)
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
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on.
If you have the traction control system, this light will
also come on when the system is limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light
comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the traction control system stops limiting
wheel spin.
The low traction light
also comes on briefly when you
turn the ignition key to
RUN. If the light doesn’t come
on then, have it fixed so it will be there to tell you when
the anti-lock
brake system or traction control system
is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area,
your engine
is too hot! It means that
your engine coolant
has overheated.
If you have been operating your vehicle under normal
driving conditions,
you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Low Coolant Light (5.7L V8 Engine)
This warning light should
come on while you are
starting your engine.
If the
light doesn’t come on, have
it repaired.
~
Your vehicle is equipped with a low coolant indicator
which is designed to detect when the coolant level drops
below set limits.
If the low coolant level sensor (on the
radiator) drops while the engine is running, the low
coolant indicator will light and remain lit until the
ignition
is turned to OFF. Check coolant level and add
coolant as needed. The low coolant light might stay on
after filling the radiator. Turn the ignition to
OFF, then
restart
the engine to verify that the low coolant light
goes out. See “Engine Coolant” in the Index.
NOTICE:
Driving with the low coolant light on could cause
your vehicle to overheat. See “Engine Overheating”
in the Index. Your vehicle could be damaged and it
wouldn’t be covered by your warranty.
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.
2-85
Page 141 of 406

This system is called OBD I1 (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 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.
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:
0 Light Flashing -- A misfire condition has been
detected. A misfiie 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.
2-86

If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
0 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 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.
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. 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. It
will take a few driving trips to turn the light
off.
2-87
Page 143 of 406

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). 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 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.
Oil Pressure Gage
\*
0
/
0 120
3800 V6 Engine 5.7L VS Engine
One of these gages may tell you there could be a
problem with
your engine oil pressure.
The engine oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) in the United States, or kpa
(kilopascals)
in Canada, when the engine is running. On
the 5.7L V8 engine, oil pressure should be 20 to 80 psi
(140 to 550 Pa). On the 3800 V6 engine, the oil pressure
should be between 20 and 120 psi (140 to 827 Wa). It
may vary with engine
speed, outside temperature and oil
viscosity, but readings above the red area show the normal
operating range. Readings
in the red area tell you that the
engine is low
on oil, or that you might have some other oil
problem. See “Engine Oil” in the Index.
Page 144 of 406
A CAUTION:
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.
I Low Oil Light
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered
by
your warranty.
LOW
OIL
Your vehicle is equipped
with an oil level monitoring
system. When you start
your engine, the warning light will come on briefly.
If
the light doesn’t come on,
have it repaired.
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil.
See “Engine Oil” in the Index.
NOTICE:
The oil level monitoring system only checks the
oil level when you are starting your engine.
It
does not keep monitoring the level once your
engine
is running. Also, the oil level check only
works when the engine has been turned
off long
enough for the oil to drain back into the oil pan.
