Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the

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
If your vehicle has the
remote keyless entry
system, the vehicle has
a content theft-deterrent
alarm system.
To activate the content theft-deterrent system,
do the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp
six times. Press the lock button again, within
three seconds, and the doors will lock. Close the
open door and the system will be activated.
If a locked door is not opened using the remote keyless
entry transmitter, or by OnStar
®, the pre-alarm will
go off. If the engine is not started or unlock not
pressed within 10 seconds, the front turn signal lamps
will ash for two minutes, and the horn will sound for
two minutes, then will turn off to save the battery power.
Remember, the theft-deterrent system will not activate
if you lock the doors with a key, the manual door lock,
or power door lock switch. The system can only be
activated using the remote keyless entry transmitter,
or by OnStar
®. SeeOnStar®System on page 2-41
for additional information. You should also remember
that you can start your vehicle with the correct ignition
key if the alarm has been set off.
Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the remote keyless
entry transmitter. Unlocking a door any other
way will set off the alarm.
2-15

If you set off the alarm by accident, you can turn off
the alarm by pressing unlock on the remote keyless
entry transmitter. The alarm will not stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or start
the engine.
If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The horn
fuse may be blown. To replace the fuse, seeFuses
and Circuit Breakers on page 5-99.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.
Passlock®
Your vehicle has 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 an incorrect key is used or
the ignition lock cylinder is tampered with, the fuel
system is disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately ve seconds after the engine is started.
SeeSecurity Light on page 3-36.
If the engine stalls and the security light ashes, wait
about 10 minutes 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 does not start after three tries, the vehicle
needs service.
If the engine is running and the security 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.
In an emergency, call the Roadside Assistance Center.
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:
Keep your speed at 55 mph (88 km/h) or less
for the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting
to brake, or slow, the vehicle.
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 4-56for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
With the key in the ignition
switch, you can turn to
four different positions.
LOCK (A):This position locks your ignition. It also
locks your transmission on automatic transmission
vehicles. It will lock your steering wheel on manual
transmission vehicles when the key is removed.
It is a theft-deterrent feature. You will only be able to
remove your key when the ignition is turned to LOCK.
2-17

If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only
with your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories or
items plugged into the accessory power outlets.
On automatic transmission vehicles, this position
unlocks the ignition. On manual transmission vehicles,
it unlocks the ignition and steering wheel. Use this
position if your vehicle must be pushed or towed.
ON (C):This is the position that the switch returns
to after you start your engine and release the switch.
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 cluster warning and indicator
lights. The transmission is also unlocked in this position
on automatic transmission vehicles.START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch will return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the
radio or items plugged into the accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and the key
is in the ignition.
Retained Accessory Power (RAP)
Your vehicle has Retained Accessory Power (RAP)
which will allow certain features of your vehicle
to continue working for up to 20 minutes after the
ignition key is turned to LOCK.
Your radio, wipers and power windows will work when
the ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features will continue to
work for up to 20 minutes or until a door is opened.
2-18

Starting the Engine
Automatic Transmission
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:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The gear selector should be in NEUTRAL and the
parking brake engaged. Hold the clutch pedal to the oor
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 the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down
as your engine gets warm.Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent starter-motor
gear damage, this system also prevents cranking
if the engine is already running. The engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or LOCK position.
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 the engine does not start within 10 seconds,
push the accelerator pedal all the way to the
oor, while you hold the ignition key in START.
When the engine starts, let go of the key and let
up on the accelerator pedal. Wait about 15 seconds
between each try.
2-19

When starting your engine in very cold weather
(below 0°F or 18°C), do this:
1. With your foot off the accelerator pedal, turn
the ignition key to START and hold it there up
to 15 seconds. When the engine starts, let go of
the key.
2. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briey but then stops again, do the
same thing, but this time keep the pedal down
for ve 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. Any resulting damage
would not be covered by your vehicle’s warranty.Engine Coolant Heater
Your vehicle may have this feature.
In very cold weather, 0°F (–18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver’s
side of the vehicle.
3. Plug it into a normal, grounded 110-volt AC outlet.
