2005 CHEVROLET OPTRA Owners Manual

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 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 see your dealer
for service as soon as possible.
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. SeeFilling 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 missingfuel 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.
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 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, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
If you have low engine oil
pressure, this light will stay
on after you start your
engine, or come on 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 by
your GM dealer.
The oil light could also come on in three other situations:
•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. The light will go out when you turn
the ignition on. If it does not come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it fixed right away.
•If you are idling at a stop sign, the light may blink
on and then off.
•If you make a hard stop, the light may come on for
a moment. This is normal.
3-38

{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.
Fog Lamp Light
The fog lamps light will
come on when the fog
lamps are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-16for 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 3-12for more
information.
3-39

Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
SeeHeadlamp High/Low-Beam Changer on page 3-10
for more information.
Daytime Running Lamps (DRL)
Indicator Light
This light will illuminate
when the Daytime Running
Lamps (DRL) are
activated. SeeDaytime
Running Lamps (DRL) on
page 3-15.
Door Ajar Light
This light will stay on until
all doors are closed and
completely latched.
If the key is in the ignition while the driver’s door is
open, you will also hear a warning chime.
Trunk Ajar Light (Sedan)
This light will come on
when the trunk is not
completely closed.
3-40

Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is turned to ON.
When the tank nears empty, the low fuel warning light
will come on. You still have a little fuel left, but you
should get more soon. SeeLow Fuel Warning Light on
page 3-41for more information.
Here are four things that some owners ask about. None
of these show 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 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 indicator moves a little when you turn a corner
or speed up.
•The gage goes back to empty when you turn off the
ignition.
Low Fuel Warning Light
This light comes on when
the fuel tank is low on fuel.
The low fuel warning light comes on when there is
approximately 2.0 gallons (7.5 liters) of fuel remaining in
the tank.
To turn the light off, add fuel to the fuel tank. SeeFilling
Your Tank on page 5-7.

Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, find
out what your audio system can do, and how to operate
all of its controls.

stopped, if it was the last selected audio source.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. You may experience an
increase in skipping, difficulty in finding tracks, and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.
Do not add paper labels to CDs, they could get caught
in the CD player.
If an error appears on the display, see “CD Messages”
later in this section.
