2007 CHEVROLET OPTRA 5 service indicator

AUTOMATIC OVERDRIVE (D):This position is
for normal driving.
Notice:Driving your vehicle if you notice that
it is moving slowly or not shifting gears as
you increase speed may damage the transaxle.
Have your vehicle serviced right away.
THIRD (3):This position is also used for normal
driving, however, it offers more power and lower
fuel economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
•When driving on hilly, winding roads.
•When going down a steep hill.
SECOND (2):This position gives you more power
but lower fuel economy. Use SECOND (2) on
hills. It can help control the vehicles speed as you
go down steep mountain roads, but then you
would also want to use your brakes off and on.
Notice:Do not drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can damage
the transaxle. Use THIRD (3) or AUTOMATIC
OVERDRIVE (D) as much as possible. Do not
shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h) or you can
damage your engine.FIRST (1):This position gives you even more
power but lower fuel economy than SECOND (2).
Use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1),
the transaxle does not shift into first gear until the
vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle.
If you are stuck, do not spin the tires.
When stopping on a hill, use the brakes, or
parking brake to hold the vehicle in place.
If there is a malfunction with the automatic
transaxle, the Check Engine Light or the HOLD
indicator light will turn on or flash. SeeMalfunction
Indicator Lamp on page 172orHold Mode Light
on page 170.
Take your vehicle to your dealer as soon as
possible.

If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly.
The airbags in your vehicle may not
inate in a crash, or they could even
inate without a crash. To help avoid
injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start
your vehicle.
The airbag readiness light should flash for a few
seconds when you turn the ignition to ON.
If the light does not come on then, have it fixed so
it will be ready to warn you if there is a problem.
Passenger Airbag Status Indicator
Your vehicle has a passenger airbag status
indicator in the clock, located in the center of the
instrument panel.
When the ignition key is
turned to ON or START,
the passenger airbag
status indicator will light
for several seconds
as a system check.
Then, after several more seconds, if the off
symbol is lit on the passenger airbag status
indicator, it means that the passenger sensing
system has turned off the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped). SeePassenger Sensing System
on page 76for more on this, including important
safety information.

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.

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
about 2.0 gallons (7.5 liters) of fuel remaining in
the tank.
To turn the light off, add fuel to the fuel tank.
SeeFilling the Tank on page 254.
Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 206. By taking a few moments to read this
manual and get familiar with your vehicle’s
audio system, you can use it with less effort, as
well as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone and adjusting the speakers. Then, when
driving conditions permit, you can tune to
your favorite stations using the presets and
steering wheel controls if the vehicle has them.

However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must not be
used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
plastic and rubber parts. That damage would
not be covered under your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your dealer for service.Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel might
be hard to find. Never use leaded gasoline or
any other fuel not recommended in the previous
text on fuel. Costly repairs caused by use of
improper fuel would not be covered by your
warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal firmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates can cause a
brake squeal when the brakes are first applied
or lightly applied. This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
specifications.
Brake linings should always be replaced as
complete axle sets.
SeeBrake System Inspection on page 381.Brake Pedal Travel
See your dealer if the brake pedal does not return
to normal height, or if there is a rapid increase
in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you apply the brakes, with or without
the vehicle moving, the brakes adjust for wear.

When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
symbol on the instrument panel cluster.
The low tire pressure warning symbol comes on at
each ignition cycle until the tires are inflated to
the correct inflation pressure.
The tire pressure warning light may come on in
cool weather when the vehicle is first started, and
then turn off as you start to drive. This could
be an early indicator that the tire pressures are
getting low and need to be inflated to the
proper pressure.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct inflation
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 236,
for an example of the tire information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 311.Your vehicle’s TPMS system can warn you about
a low tire pressure condition but it does not
replace normal tire maintenance. SeeTire
Inspection and Rotation on page 316andTires
on page 303.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
See your dealer for service if all TPMS sensors are
installed and the low tire pressure warning light
comes on and stays on.
