2007 CHEVROLET OPTRA 5 Owners Manual

Anti-Lock Brake System
Warning Light
If your vehicle has an
Anti-Lock Brake System
(ABS), this light will
come on when the
ignition is turned to
ON and may stay on
for several seconds.
That is normal.
If the light stays on, turn the ignition to LOCK.
If the light comes on, 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.
See your dealer. 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 168.
The ABS warning light will come on briefly when
you turn the ignition to ON. This is normal.
If the light does not come on then, have it fixed so
it will be ready to warn you if there is a problem.
169

Speed Sensitive Power
Steering (SSPS) Warning Light
If your vehicle has
Speed Sensitive Power
Steering, this warning
light will come on briefly
when you turn the
ignition to ON as a check
to show you it is working.
Then it should go out after a few seconds.
If the warning light does not come on, have it fixed
so it will be able to warn you if there is a problem.
If the warning light stays on, or comes on while
you are driving, the system may not be working.
If this happens, see your dealer for service.
Hold Mode Light
If your vehicle has this
feature, this light will
come on when the hold
mode is active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” underAutomatic
Transaxle Operation on page 110for additional
information on this feature.
170

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant
temperature gage.
With the ignition turned
to ON, 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.
SeeEngine Overheating on page 271.
Tire Pressure Light
This light comes on
briefly when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are significantly underinflated.
Stop and check your tires as soon as it is safe to
do so. If underinflated, inflate to the proper
pressure. SeeTires on page 303for more
information.
This light will flash for about 75 seconds and then
stay on if a problem is detected with the Tire
Pressure Monitor system.
SeeTire Pressure Monitor System on page 312
for more information.
171

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or replacement tires that do not
match your vehicle’s original tires 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. SeeAccessories
and Modifications on page 249.
When the ignition is on, this light should come on
and should go out after a few seconds as a
check to show you it is working. If the light does
not come on, have it repaired.
172

This light will also come on during a malfunction in
one of two ways:
•Light Flashing— A misfire condition has
been detected. A misfire 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.
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 the Tank on page 254.
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.
173

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.
SeeGasoline Octane on page 251. 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 dealer can prepare the vehicle for
inspection.
174

Oil Pressure Light
If your vehicle has 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 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.
{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.
175

Fog Lamp Light
The fog lamp 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 150for more
information.
Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is
turned off. SeeCruise Control on page 145
for more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
SeeHeadlamp High/Low-Beam Changer on
page 142for more information.
Daytime Running Lamps (DRL)
Indicator Light
This light will come on
when the Daytime
Running Lamps (DRL)
are activated. See
Daytime Running
Lamps (DRL) on
page 149.
