Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1

Section 2 Features and Controls
2-1

One key is used for the
ignition, the door and all
other locks.When a new vehicle is delivered, the dealer removes
the key tag and gives it to the first owner. The tag has a
code on it that tells your dealer how to make extra keys.
For vehicle security, keep the key tag in a safe place and
also record the key number somewhere other than inside
of the vehicle. If you lose your key, you will be able to
have a new one made easily using the tag.
Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. Even if a key has the same profile,
it will not start the engine if the electronic code is
incorrect. 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.
2-3

Lockout Protection
If your vehicle has remote keyless entry, you have
lockout protection. This feature stops the driver’s door
lock from locking when the driver’s door is open.
Leaving Your Vehicle
If you are leaving your vehicle, take your keys. All of the
doors, except for the driver’s door, can be locked
from the outside by pushing down the door lock and
then closing the door. The driver’s door can only
be locked from the outside by using the key or the
optional remote keyless entry transmitter.
Trunk (Sedan)
{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 2-32.
To open the trunk on your sedan from outside of your
vehicle, insert the key into the lock cylinder and turn the
key clockwise.
2-10

Liftgate (Hatchback)
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the liftgate open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
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. SeeClimate Control
System on page 3-12.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-32.To open the liftgate on your hatchback from outside of
the vehicle, insert the key into the lock cylinder and
turn it counterclockwise. Then pull up the handle above
the license plate to open the liftgate.
When closing the liftgate, close from the center to
ensure it fully latches. Although you may use one hand
to unlock the liftgate, it is recommended that two
hands on the upper surface be used to close the liftgate.
To lock the liftgate, insert the key into the lock cylinder
and turn it clockwise.
The liftgate can also be locked or unlocked by the
central door unlocking system. SeeCentral Door
Unlocking System on page 2-8.
2-12

To avoid activating the alarm by accident, do one of the
following:
•Unlock the driver’s or passenger’s front door using
the key.
•Press the unlock button on the remote keyless
entry transmitter.
Unlocking a door any other way will activate the alarm
when a door or the trunk or liftgate is opened.
If you do not want to arm the theft-deterrent system,
lock the vehicle using the key or the manual door locks.
Disarming the System
To disarm the system, do one of the following:
•Unlock the driver’s or passenger’s front door using
the key.
•Press the unlock button on the remote keyless
entry transmitter.
- The LED on the transmitter will flash once.
- All of the doors will unlock.
- The hazard warning lamps will flash twice.
- The theft-deterrent mode will disarm.
If the door is not opened or if the engine is not started
within 30 seconds after disarming the system using
the transmitter, all of the doors will automatically lock
and the theft-deterrent mode will rearm.
How the System Alarm is Activated
If a door or the trunk or liftgate is opened without using
the key or the remote keyless entry transmitter, the horn
will sound and the lamps will flash for up to 30 seconds.
How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated using
one of the following methods:
•Press the lock or unlock buttons on the remote
keyless entry transmitter.
•Unlock the driver’s or passenger’s front door using
the key.
Otherwise, the alarm will automatically stop after
30 seconds. The system will then lock the doors and
rearm the theft-deterrent system.
How to Detect a Tamper Condition
If the hazard warning lamps flash once when you press
the lock or unlock buttons on the remote keyless
entry transmitter, the theft-deterrent system alarm was
activated while you were away.

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 in the secondary information center
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 5-85. 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 have a new key made.
Up to five keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer can
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 4-37for more information.
2-18

Ignition Positions
With the key in the ignition
switch, you can turn the
key to four different
positions.
{CAUTION:
On manual transaxle vehicles, turning the key
to LOCK and removing it 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 ACC. Do not push
the key in 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.
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.

Starting Your Engine
Automatic Transaxle
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.
Manual Transaxle
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the floor and
start the engine. Your vehicle will not start if the clutch
pedal is not all the way down — that is a safety feature.
Starting Your Engine
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 it does not start, wait about 15 seconds and try
again to start the engine by turning the ignition key to
START. Wait about 15 seconds between each try.
When your engine has run about 10 seconds to
warm up, your vehicle is ready to be driven. Do not
race your engine when it is cold.
If the weather is below freezing (32°F or 0°C),
let the engine run for a few minutes to warm up.
3. If your engine still 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 about three seconds. If the vehicle starts
briefly but then stops again, do the same thing, but
this time keep the pedal down for five or six seconds.
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.
