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 your
vehicle. Many times, this damage would not be covered
by your vehicle’s 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.
There are also warning labels on your 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 following
topics:

iv

In many crashes severe enough to inate 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 inate only once. After an
air bag inates, you’ll 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.
Your vehicle is equipped with two electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also 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 ination and driver’s safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
Let only qualied 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 the air
bag covering on the driver’s and right front
passenger’s seatback, the air 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 both the air bag module
and seatback for the driver’s and right front
passenger’s side impact air bag. Do not open or
break the air bag coverings.

Liftgate
To unlock or lock the liftgate from the outside, use the
remote keyless entry transmitter. For more information,
seeRemote Keyless Entry System Operation on
page 2-5.
Open the liftgate using the handle located above the
license plate. Once slightly opened, the liftgate will rise
by itself. Lamps in the rear of the vehicle will come
on, illuminating the rear cargo area. SeeInterior Lamps
on page 3-14.
Notice:If you open the liftgate without checking for
overhead obstructions such as a garage door,
you could break the liftgate glass. Always check to
make sure the area above the liftgate is clear
before opening it.{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 3-21.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-43.
2-22

To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Don’t drive with the liftgate open,
even slightly. SeeEngine Exhaust on page 2-43.
A message in your instrument panel cluster will warn
you if the liftgate is not completely closed. See
Rear Hatch Ajar Warning Message on page 3-46.

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 the PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III is a passive
theft deterrent system. This
means you do not have to
do anything different 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 being delivered 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.
If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
2-29

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 instrument panel PASS
KEY fuse. 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 or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit Breakers
on page 5-96.
It is possible for the PASS-Key
®III decoder to learn the
transponder value of a new or replacement key. Up
to 10 additional keys may be programmed for the
vehicle. This procedure is for learning additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith
who can service PASS-Key
®III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III to get a new key blank that is cut exactly
as the ignition key that operates the system.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
®III to
have new keys made. To program additional keys you
will need two current driver’s keys, black in color.
You must add a step to the following procedure. After
Step 3, repeat Steps 1 through 3 with the second current
driver’s key. Then continue with Step 4.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the ignition key in the ignition and start the
engine. If the engine will not start, see your dealer
for service.
3. After the engine has started, turn the key to OFF
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer or a locksmith who can service PASS-Key®III to
have a new key made.

Ignition Positions
With the key in the ignition, you can turn it to ve
different positions.
A (ACCESSORY):This is the position in which you can
operate your electrical accessories. Press in the ignition
switch as you turn the top of the key toward you.
B (LOCK):This is the only position from which you can
remove the key. This position locks your ignition and
transaxle.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
none of this works, then your vehicle needs service.
C (OFF):This position unlocks the ignition and
transaxle, 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.
D (RUN):This is the position to which the switch
returns after you start your engine and release the
ignition key. This is the position for driving. Even when
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 ignition key. The switch
will return to RUN for normal driving.
If the engine is not running, ACCESSORY and RUN are
positions that allow you to operate your electrical
accessories, such as the radio.
Retained Accessory Power (RAP)
With RAP, the power windows, power rear quarter
windows, audio system and the automatic level control
will continue to work up to 10 minutes after the ignition
key is turned to OFF and none of the doors are opened.
