CHEVROLET MALIBU 2005 5.G Owners Manual

The Driver Information Center (DIC) may display a
Low Brake Fluid or Push Park Pedal message. These
messages might help to determine why the brake
system warning light is on. SeeDIC Warnings and
Messages on page 3-55.
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. SeeTowing Your Vehicle on
page 4-34.
{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 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. If the light
comes on and the chime sounds 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, 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 3-40earlier in this section.
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 does not come on then, have it xed
so it will be ready to warn you if there is a problem.
3-41

Enhanced Traction System
Warning Light
If your vehicle has
the Enhanced Traction
System (ETS), this
light may come on for
the following reasons:
If you turn the system off by pressing the
TC (traction control) button located on the center
console, the light will come on and stay on.
To turn the system back on, press the button
again and the warning light should go out.
If there’s a brake system problem that is specically
related to traction control, the ETS 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.
3-42

Enhanced Traction System
Active Light
If your vehicle has
the Enhanced Traction
System (ETS), 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
system stops limiting wheel spin.
3-43

Engine Coolant Temperature
Warning Light
This light indicates that
the engine coolant
has overheated or the
radiator cooling fan is
not working.
This light will come on briey when you turn on the
ignition as a check to show you it is working.
If the light comes on and the vehicle has been operating
under normal driving conditions, pull off the road, stop
the vehicle, and turn off the engine as soon as possible.
SeeCooling System on page 5-26for more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, the light
comes on and you hear a chime, your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal driving conditions and the gage reads hot,
you should pull off the road, stop your vehicle and
turn off the engine as soon as possible.
SeeEngine Overheating on page 5-24.

Malfunction Indicator Lamp
Check Engine Light
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 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:Modications 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.
Modications 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 does not come on, have
it repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre 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.
3-45

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 hauled as soon as it is possible
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
dealer 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 5-8.
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.
3-46

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline 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, misring,
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 dealer can check the vehicle. Your dealer 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 GM dealer can prepare the vehicle for
inspection.
3-47

Oil Pressure Light
If you have low engine
oil pressure, 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 xed immediately.
This light will come on briey when you turn on
the ignition as a check to show you it is working. If it
does not come on with the ignition on, you may have
a problem with the bulb. Have it xed right away.{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.
3-48

Security Light
This light will come on
briey when you turn the
key toward start. The
light will stay on until the
engine starts.
If the light comes on continuously while driving
and stays on, there may be a problem with the
PASS-Key
®III + system. Your vehicle will not be
protected by PASS-Key®III +, and you should see
your dealer.
If your vehicle has the content theft-deterrent alarm
system, the security light will also turn on to indicate that
arming has been initiated. SeeContent Theft-Deterrent
on page 2-18for more information.
Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is turned off.
SeeCruise Control on page 3-11for more information.
Highbeam On Light
This light will come on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.
Service Vehicle Soon Light
This light will come on and
a chime will sound if it
detects a problem on the
vehicle.
The Driver Information Center (DIC) may display a
message such as Low Coolant, Power Steering, Engine
Reduced Power, etc. These messages may help you
determine why the service vehicle soon indicator is on.
SeeDIC Warnings and Messages on page 3-56.If
this happens, see your GM dealer for necessary repairs
to maintain top vehicle performance.
3-49

Fuel Gage
Your fuel gage tells you about how much fuel you
have left, when the ignition is on. When the indicator
nears empty, the amber light located left of the
pump symbol will come on and you will hear a chime.
You still have a little fuel left, but you should get
more soon. The arrow on the fuel gage points to
side of the vehicle with the fuel door.Here are four things that some owners ask about.
These are normal and do not indicate a problem with
your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll 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
ll the tank.
The indicator moves a little when you turn a corner
or speed up.
The gage goes back to empty when you turn off the
ignition.
