2007 CHEVROLET OPTRA 5 battery

Clock
Your vehicle has a digital clock. If you have the
wagon, the clock is located in the center of the
instrument panel below the air outlets. If you have a
hatchback, the clock is located in the center of the
instrument panel above the air outlets. When the
ignition is turned to ACC or ON, the time is
displayed in the digital clock. There are
three adjusting buttons for the digital clock:H (Hour):To go forward one hour, press the
H button once. To go forward more than one hour,
press and hold the button until the correct hour
is reached.
M (Minute):To go forward one minute, press
the M button once. To go forward more than
one minute, press and hold the button until the
correct minute is reached.
S (Set):To reset the time to the nearest hour,
press the S button.
For example, if this button is pressed while the
time is between 8:00 and 8:29, the display is set to
8:00. If this button is pressed while the time is
between 8:30 and 8:59, the display is set to 9:00.
After disconnecting the battery or replacing the
fuse, reset the clock.

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something may
be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger’s seat
may not have the protection of the frontal
airbag and side airbag (if equipped).
SeeAirbag Readiness Light on page 164
for more on this, including important safety
information.
Charging System Light
The charging system
light will come on briefly
when you turn on the
ignition, and the engine
is not running, as a
check to show you it
is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging
system. Have it checked by your dealer. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
167

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.

You can run the engine to keep warm, but be
careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO
(carbon monoxide) gas to get inside. CO
could overcome you and kill you. You
cannot see it or smell it, so you might not
know it is in your vehicle. Clear away
snow from around the base of your
vehicle, especially any that is blocking the
exhaust pipe. And check around again
from time to time to be sure snow does
not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run your engine only as long as you must.
This saves fuel. When you run the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.
234

You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do it as
little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
will need to spin the wheels, but you do not
want to spin your wheels too fast. The method
known as rocking can help you get out when you
are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. And, the transaxle or
other parts of the vehicle can overheat.
That could cause an engine compartment
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h) as
shown on the speedometer.
Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you
spin the wheels too fast while shifting
the transaxle back and forth, you can destroy
the transaxle. SeeRocking Your Vehicle to
Get It Out on page 236.
For information about using tire chains on your
vehicle, seeTire Chains on page 323.

Replacing Brake System Parts
The braking system on a vehicle is complex.
Its many parts have to be of top quality and work
well together if the vehicle is to have really
good braking. Your vehicle was designed and
tested with top-quality GM brake parts. When you
replace parts of the braking system — for
example, when the brake linings wear down and
you need new ones put in — be sure you get new
approved GM replacement parts. If you do not,
the brakes might not work properly. For example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between the front
and rear brakes can change — for the worse.
The braking performance you have come to expect
can change in many other ways if someone
puts in the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. SeeEngine Compartment Overview
on page 258for battery location.Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep
your battery from running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 285for tips on working
around a battery without getting hurt.
