2004 CHEVROLET MONTE CARLO warning light

Voltmeter Gage
If your vehicle is equipped
with the 3800 V6 engine it
has a voltmeter gage
that indicates battery
voltage.
If the gage reads less than 12 volts or more than
16 volts while the engine is running, and it stays there,
you may have a problem with the electrical charging
system.
Also, when your gage reads less than 11 volts or more
than 16 volts, your battery life indicator will be
illuminated in the message center. For more information
seeBattery Warning Message on page 3-45.
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.
The LOW BRAKE FLUID message in the message
center will also appear when there is a brake problem.
SeeLow Brake Fluid Warning Message on page 3-50.
Have your brake system inspected right away.

This light should come on briey when you turn the
ignition key to ON. If it doesn’t come on then, have it
xed 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
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeBrake System
Warning Light on page 3-35andTowing Your Vehicle on
page 4-31.
{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 have pulled off the road and
stopped carefully, have the vehicle towed for
service.

Anti-Lock Brake System Warning
Light
If your vehicle has ABS,
the anti-lock brake system
warning light will come
on for a few seconds when
you turn the ignition key
to ON.
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, the anti-lock brake system
needs service and you don’t have anti-lock brakes.
The anti-lock brake system warning light will come on
briey when you turn the ignition key to ON. This is
normal. If the light doesn’t come on then, have it xed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
If your vehicle has the
traction control system,
this warning light may
come on for the following
reasons:
If you turn the system off by pressing the TRAC OFF
button located on the center console, a chime will
sound and 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. SeeTraction
Control System (TCS) on page 4-10for more
information.
If there’s a 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 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 warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Low Fuel Warning Message
This message is displayed when your vehicle is low on
fuel. Four chimes will also sound.
Refer to the fuel gage for a better indication of the
amount of fuel remaining in the fuel tank.
Low Brake Fluid Warning Message
This message will be displayed when your vehicle has
a brake problem. The brake system warning light
will also be illuminated.
If this message appears, the brakes aren’t working
properly. You should have your vehicle serviced
immediately. SeeBrake System Warning Light on
page 3-35for more information. United States

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.

Traction Control System (TCS)
Your vehicle is equipped with a Traction Control System
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle and apply the front brakes to
limit wheel spin.
This light will come on when your Traction Control
System is limiting wheel spin. SeeTraction Active
Message on page 3-43.
You may feel or hear the system working, but this is
normal.If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control Light
on page 3-41.
The Traction Control System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you’ve
chosen, so you should use the lower gears only
when necessary. SeeAutomatic Transaxle Operation on
page 2-21.
When the system is on,
this warning light will come
on to let you know if
there’s a problem.
SeeTraction Control System (TCS) Warning Light on
page 3-36. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly. United States

To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction Control
System on. But you can turn the system off if you
ever need to.
You should turn the system off if your vehicle ever gets
stuck in sand, mud or snow and rocking the vehicle
is required. SeeIf You Are Stuck: In Sand, Mud, Ice or
Snow on page 4-30.
To turn the system on or
off, press the TRAC OFF
button on the console.When you turn the system off, a chime will sound and
the Traction Control System warning light will come
on and stay on. If the Traction Control System is limiting
wheel spin when you press the button to turn the
system off, the warning light will come on and the
system will turn off right away.
You can turn the system back on at any time by
pressing the button again. The Traction Control System
warning light should go off.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
Hydroplaning does not happen often. But it can if your
tires do not have much tread or if the pressure in
one or more is low. It can happen if a lot of water is
standing on the road. If you can see reections
from trees, telephone poles or other vehicles, and
raindrops “dimple” the water’s surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just is not a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle.
If you can not avoid deep puddles or standing water,
drive through them very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong forces.
If you try to drive through owing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of
owing water can carry away a smaller vehicle.
If this happens, you and other vehicle
occupants could drown. Do not ignore police
warning signs, and otherwise be very cautious
about trying to drive through owing water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.
Have good tires with proper tread depth. SeeTires
on page 5-65.
