2004 Chevrolet Epica Owner ManualM

What Will You See After an Air Bag
Inates?
After the air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module – the
steering wheel hub for the driver’s air bag, the instrument
panel for the right front passenger’s bag, the side of the
seatback closest to the door for the driver’s side impact
air bag – will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but not too
hot to touch. There will be some smoke and dust coming
from the vents in the deflated air bags. Air bag inflation
does not prevent the driver from seeing or being able to
steer the vehicle, nor does it stop people from leaving
the vehicle.
{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is
CAUTION: (Continued)
CAUTION: (Continued)
safe to do so. If you have breathing problems
but can’t get out of the vehicle after an air
bag inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment,
you should seek medical attention.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation. Additional
windshield breakage may also occur from the right front
passenger air bag.
•Air bags are designed to inflate only once. After an
air bag inflates, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you in
another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
1-53

•Your vehicle is equipped with a crash sensing
and diagnostic module, which records information
about the frontal air bag system. The module
records information about the readiness of the
system, when the system commands air bag
inflation and driver’s safety belt usage at deployment.
The module also records speed, engine rpm,
brake and throttle data.
•Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
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 air bag, or an air
bag covering on a seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or the air bag module and
seatback for a side impact air bag. Do not open
or break the air bag coverings.
Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air bag can still inate during improper
service. You can be injured if you are close
to an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag systems do not need regular maintenance.

Remote Keyless Entry System
If equipped, the keyless entry system operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.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 2-5.
•If you are still having trouble, see your dealer or
a qualified technician for service.

Immobilizer
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine. The
immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is turned
to LOCK and removed from the ignition. The security light
located on the top center of the instrument panel, near
the windshield, will flash when the immobilizer is active. If
the light does not flash after removing the key, have the
system checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
2-17

When trying to start the vehicle, if the engine does
not start and the security light continues flashing, the
key may have a damaged transponder. Turn the ignition
off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you may
also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-79. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty. See your
dealer who can service the theft-deterrent system to
have a new key made.
Up to four keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer
can service the theft-deterrent system to have new
keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program
on page 7-6.Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in.
SeeTowing a Trailer on page 4-35for
more information.
2-18

Ignition Positions
With the key in the
ignition switch, you
can turn the key to
four different positions.
Notice:If your key seems stuck in LOCK and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? If it is, then turn
the steering wheel left and right while you turn
the key hard. Turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of these works, then
your vehicle needs service.LOCK:This position locks your steering wheel, ignition,
shift lever and transaxle. This is the only position in
which you can insert or remove the key. For easier key
operation when unlocking the steering wheel, move the
steering wheel from right to left and turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories, such as the radio, but
not the ventilation fan.
ON:This is the position to which the switch returns
after you start your engine and release the key.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON to operate your electrical accessories, and to display
some instrument panel warning lights.
START:This position starts the engine. When the
engine starts, release the key. The switch will return to
ON for normal driving. Do not turn the key to START
if the engine is running.
Even if the engine is not running, ACC and ON allow
you to operate electrical accessories, such as the radio.
2-19

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags 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 air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should turn on 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.
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.
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.
3-34

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not 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 to ON. If it does
not come on then, have
it fixed so it will be ready
to warn you if there is
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 does not fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
floor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-29.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
3-35

Anti-Lock Brake System Warning
Light
If your vehicle has an
anti-lock brake system,
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. Or, 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. 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 3-35.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key 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.
Speed Sensitive Power Steering
(SSPS) Warning Light
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 SSPS system may not be working. If this
happens, see your dealer for service.
