battery CHEVROLET CLASSIC 2005 Owners Manual

•Your vehicle is equipped with a crash sensing and
diagnostic module which records information after a
crash. SeeVehicle Data Collection and Event Data
Recorders on page 7-8.
•Let only qualified technicians work on your airbag
system. Improper service can mean that your airbag
system will not work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the airbag
may not work properly. You may have to replace the
airbag module in the steering wheel or both the
airbag module and the instrument panel for the right
front passenger’s airbag. Do not open or break
the airbag coverings.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inflate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-10.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Restraint System Check
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
•Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
•Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
•Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or
a qualified technician for service.
Remote Keyless Entry System
Operation
The following functions are
available with the keyless
entry system:
Q(Lock):Press the lock button to lock all of the
doors. The interior lamps will turn off after all of
the doors are closed.
2-4

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
To replace the battery in the remote keyless entry
transmitter:
1. Use a flat object like a coin to separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the new
one. Make sure the positive side of the battery
faces up. Use one three-volt, CR2032, or
equivalent, type battery.
3. Put the two halves back together. Make sure the
cover is on tightly, so water won’t get in.
2-6

Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow the radio to
continue to work up to 10 minutes after the ignition is
turned to OFF.
Your radio will work when the ignition key is in ON or
ACCESSORY. Once the key is turned from ON to OFF,
the radio will continue to work for up to 10 minutes or
until any door is opened.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer
than 15 seconds at a time will cause your battery
to be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If your engine will not start, or starts but then stops,
it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key
in START for not more than 15 seconds at a time.
This clears the extra gasoline from the engine.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Instrument Panel Brightness
The thumbwheel for this
feature is located on the
instrument panel to the
left of the steering wheel.
Move the thumbwheel to the right to brighten the lights
or to the left to dim them.
Dome Lamp
The switch on this lamp has three positions. The ON
position will turn on the lamp. The DOOR position
will turn on the lamp while a door is opened. The
OFF position will shut off the lamp completely, even
while a door is opened.
Entry/Exit Lighting
When you open any door, the dome lamp inside your
vehicle will go on. This lamp will fade out 10 seconds
after the last door is closed, or when the ignition
is turned on after all doors have been closed. This lamp
will also go on when you press the trunk release
button, the unlock button or the horn button on the
remote keyless entry transmitter.
The lamps inside of your vehicle will stay on for about
10 seconds after your key is removed from the ignition
to provide an illuminated exit.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle’s battery.
When any interior lamp (trunk, reading, footwell, visor
vanity or glove box) is left on when the ignition is
turned off, the battery run-down protection system will
automatically shut the lamp(s) off after 20 minutes.
This will avoid draining the battery.
3-16

To reactivate the interior lamps, do one of the following:
•Turn on the ignition,
•turn the exterior lamp control off and then on,
•open a door,
•press any remote keyless entry transmitter button
(if equipped),
•press the remote trunk release button, or
•press the power door lock switch.
The battery run-down feature will also be activated
when any door on the vehicle is left open and the
ignition is in OFF.
Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The accessory power outlet is located to the right of
the ashtray.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information
on accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
3-17

Charging System Light
The charging system light
will come on for a few
seconds when you turn on
the ignition as a check
to show you it is working.
If it stays on, or comes on while you are driving and
you hear a chime, you may have a problem with
the electrical charging system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. 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.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come
on briefly when you turn
the ignition key to ON.
If it doesn’t come on then,
have it fixed so it will
be ready to warn you if
there’s a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.

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
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 fixed immediately.
This light will come on briefly 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 fixed right away.
3-32

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 your 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. 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.
