2005 Chevrolet Cavalier Owner ManualM

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in another
crash. A new system will include airbag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
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 7-9.
Let only qualied 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, or the airbag
covering on the driver’s and right front passenger’s
seatback, the airbag may not work properly. You may
have to replace the airbag module in the steering
wheel, both the airbag module and the instrument
panel for the right front passenger’s airbag, or both
the airbag module and seatback for the driver’s and
right front passenger’s side impact 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
inate 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 7-11.
{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
Checking Your Restraint Systems
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.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
1-55

One key is used for the
ignition, the doors and all
other locks.
When a new vehicle is delivered, the dealer removes
the key tag from the key and gives it to the rst owner.
Each tag has a code on it that tells your dealer or a
qualied locksmith how to make extra keys. Keep the
tag in a safe place. If you lose your key, you will be able
to have a new one made easily using the tag.
If you need a new key, contact your dealer who can
obtain the correct key code. SeeRoadside Assistance
Program on page 7-6for more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.If your vehicle is equipped with the OnStar®system with
an active subscription and you lock your keys inside
the vehicle, OnStar
®may be able to send a command to
unlock your vehicle. SeeOnStar®System on page 2-33
for more information.

If equipped, the remote 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 modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
2-3

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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
“Remote Keyless Entry System Operation” following
this section.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet
(1 m) up to 30 feet (9 m) away using the remote keyless
entry transmitter supplied with your vehicle.
In addition, the system illuminates the interior lamps for
a set period of time. Also, a content theft security
system can be activated to monitor and set a horn alarm
if the vehicle’s door or trunk is opened without rst
unlocking the door or trunk with the remote keyless entry
transmitter.
The remote keyless entry system consists of a receiver,
which is located in the vehicle, and two hand held
transmitters.
2-4

To replace the battery in the transmitter:
1. Use a coin or similar object 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 down. For battery replacement, use a
three-volt battery, type CR2032, or equivalent.
3. Read the instructions inside the case.
4. Put the two halves back together. Make sure the
cover is on tightly, so water will not get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent to it
more than once.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for at least 10 seconds. During this
time, the doors should lock and unlock once. This
conrms the resynchronization. If the doors do
not lock and unlock, see your dealer for service.

How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated by:
Pressing the LOCK or panic button on the
transmitter to turn off the alarm. The system will
re-arm if all doors and the trunk are later closed.
Pressing the UNLOCK or trunk button on the
transmitter to turn off the alarm and disarm
the system.
Putting the key in the ignition and turning it to
START to turn off the alarm and disarm the system.
How to Detect a Tamper Condition
If you hear three horn chirps when you press the
UNLOCK, LOCK or trunk release buttons on your
transmitter, the content theft security system alarm was
triggered while you were away.
Your dealer can change the settings to disable the
headlamp ash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp
twice on the rst press of the UNLOCK button. See your
dealer for more information.
Passlock®
Your vehicle is equipped with the
Passlock®theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
During normal operation, the THEFT SYSTEM light
will go off approximately ve seconds after the key is
turned to the RUN ignition position following an
engine start.
If the engine stalls and the THEFT SYSTEM light
ashes, wait until the light stops ashing before trying to
restart the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the THEFT SYSTEM light
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and must be
serviced by your dealer. Your vehicle is not protected
by Passlock
®at this time. See your dealer for service.
Or seeRoadside Assistance Program on page 7-6
for more information.
You may also want to check the fuses. SeeFuses and
Circuit Breakers on page 5-81.

{CAUTION:
On manual transaxle vehicles, turning the key
to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to OFF. Don’t press the key
release button while the vehicle is moving.
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.C (OFF):This position unlocks the steering wheel (for
vehicle’s equipped with a manual transaxle) and
ignition, but does not send power to any accessories.
Use this position if your vehicle must be pushed or
towed, but never try to push-start your vehicle. A
warning chime will sound if you open the driver’s door
when the ignition is in OFF and the key is in the ignition.
D (RUN):This is the position to which the switch
returns after you start your engine and release the
switch. The switch stays in RUN while the engine
is running. But even while the engine is not running, you
can use RUN to operate your electrical accessories,
and to display some instrument panel warning lights.
E (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to RUN for normal driving.
Even if the engine is not running, ACCESSORY and
RUN allow you to operate electrical accessories,
such as the radio.
