2004 CHEVROLET MALIBU ECU

{CAUTION:
Both frontal and side impact air bags inate
with great force, faster than the blink of an
eye. If you’re too close to an inating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag ination before
and during a crash. Always wear your safety
belt even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Occupants
should not lean on or sleep against the door.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”

If your vehicle has a side impact air bag for the right
front passenger and the person directly behind that
passenger, it is located in the ceiling above the
side windows.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering. And, because your vehicle has
side impact air bags, never secure anything to
the roof of your vehicle by routing the rope or
tiedown through any door or window opening.
If you do, the path of an inating side impact
air bag will be blocked. The path of an inating
air bag must be kept clear.

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It also starts up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to the on position. A remote start occurs when buttons
on the remote keyless entry transmitter are pressed.
Laws in some local communities require that a person
using remote start have the vehicle in view when
doing so and may prohibit the execution of remote start
if not in view of the vehicle. Check local regulations
for any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts,
each with 10 minutes of engine running. Or it provides
one start with 10 minutes of engine running, which can be
extended by 10 more minutes, for 20 minutes of total
running time. Once two starts or 20 minutes running time
has been provided, the vehicle must be started normally
with the ignition key to get more remote starts.The remote start feature will not operate if the key is in
the ignition or the hood is not closed.
Your remote keyless entry transmitter, with the remote
start button, provides an increased range of operation.
However, the range may be less while the vehicle
is running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, see “Remote Keyless
Entry System Operation” previously in this section.
/(Remote Start):Press the lock button and then
press this button to use the remote start feature.
To start the vehicle using the remote start feature, do
the following:
1. Aim the transmitter at the vehicle.
2. Press the transmitter’s lock button, release it and
then immediately press and hold the transmitter’s
remote start button until the vehicle’s turn signal
lights ash or for at least four seconds. The
vehicle’s doors will be locked.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
4. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension.

Lockout Protection
Lockout protection is intended to provide enhanced
security and convenience. This feature prevents
the driver’s door from being locked using the power
door locks. If the key is left in the ignition and a door is
open, pressing the power door lock switch will lock
all the doors and then unlock the driver’s door.
Pressing and holding down the power door lock switch
for more than three seconds or until the driver door
locks, will override this feature.
This feature cannot guarantee that you will never be
locked out of your vehicle. If you don’t leave the key in
the ignition, or if you use the manual door lock or
the remote keyless entry transmitter, you could still lock
your key inside your vehicle. Always remember to
take your key with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and set
the locks from the inside, then get out and close the door.
Trunk
To unlock the trunk on the sedan manually from the
outside, insert the key and turn the trunk lock cylinder.
When closing the trunk, close from the center to
ensure it fully latches.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.

Remote Trunk/Liftgate Release
Press the remote release
button, located on the
lower edge of the driver’s
door, to open the trunk
lid or the liftgate.
The remote trunk release will only work when either the
ignition is off, or with the ignition in ON while the
vehicle is in PARK (P) or NEUTRAL (N).
Emergency Trunk Release Handle
Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located inside the trunk of the sedan model on
the trunk latch. This handle will glow following
exposure to light. Pull the release handle up to open the
trunk from the inside.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have a
content theft-deterrent
alarm system.
Arming the System
With the ignition off, you can initiate arming of the
system by:
Pressing the remote keyless entry transmitter lock
button
Pressing the power door lock switch and the
driver’s door is open or
With the doors closed, turning the driver’s door key
lock cylinder toward the front of the vehicle.
The system will arm thirty seconds after all the doors
and the liftgate are closed.
If the lock button on the transmitter is pressed again
within ve seconds, the system will arm immediately.
The security light will turn on to indicate that arming has
been initiated. Once the system is armed, the security
light will ash once every three seconds and remain
ashing.
If the security light is ashing twice per second, this
means that a door or the liftgate is open.
If you don’t want to arm the system, lock the car with
the lock levers on the doors.
2-18

Disarming the System
If the system is armed, you can disarm the system by:
Pressing the unlock button on the transmitter
Turning the ignition to ON or
Turning the driver’s door key lock cylinder once
toward the rear of the vehicle.
Once the system is disarmed, the security light will stop
ashing.
How the System Alarm is Activated
If the system is armed,
Opening the driver’s door will cause a ten second
pre-alarm chirp followed by a thirty second full
alarm of horn and lights.
Opening any other door or the liftgate will
immediately cause a full alarm for thirty seconds of
horn and lights.
If an alarm event has nished and all the doors and the
liftgate are closed, the system will re-arm itself.
How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated by:
Pressing the lock button on the transmitter to
turn off the alarm. The system will also re-arm itself.
Pressing the unlock button on the transmitter to turn
off the alarm and disarm the system
Putting the key in the driver’s door key lock cylinder
and turning it to the rear of the vehicle to turn off
the alarm and disarm the system or
Putting the key in the ignition and turning it to ON
to turn off the alarm and disarm the system.
How to Detect a Tamper Condition
If you hear three chirps when you press the unlock and
lock buttons on the transmitter, that means the
content theft security system alarm was triggered while
you were away.

PASS-Key®III+
Your PASS-Key®III + 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 harmful 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 modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
®III + uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III +
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III + is a passive
theft-deterrent system. This means you don’t have to do
anything special to arm or disarm the system. It works
when you insert or remove the key from the ignition.
When the PASS-Key
®III + system senses that someone
is using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel will
stop owing to the engine. Anyone using a trial-and-error
method to start the vehicle will be discouraged because
of the high number of electrical key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light in the instrument
panel cluster comes on, 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 ignition key. At this time,
you may also want to check the fuse, seeFuses
on page 5-88. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the rst key may be faulty. See your dealer
who can service the PASS-Key
®III + to have a new
key made. In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6for more information.
