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 don’t 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.
When trying to start the vehicle 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.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
and Circuit Breakers on page 5-86. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, thefirst key may be
faulty. See your dealer who can service the
PASS-Key
®III to have a new key made.
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 who can service PASS-Key
®III to get a
new key blank that is a 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.

Retained Accessory Power (RAP)
With RAP, the power windows, the audio system, the
sunroof 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.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position–that’sa
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Don’t try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
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 warms up.
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 doesn’t start in 10 seconds, push the
accelerator pedal about one-quarter of the way
down while you turn the key to START. Do this until
the engine starts. As soon as it does, let go of
the key.
3. If your engine still won’t start (or starts but then
stops), it could beflooded 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 a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine
still won’t start or starts briefly but then stops again,
repeat Step 1 or 2, depending on the temperature.
When the engine starts, release the key and
the accelerator pedal.
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 don’t, your engine
might not perform properly.

Instrument Panel Switchbank
There is an instrument panel switchbank located below
the comfort controls. It contains switches or blanks
that will vary with the options that are on your vehicle.
The switches you may have are:
•Rear Window Wiper/Washer
•Liftgate Release
•Traction Disable
•Park Aid Disable
•Heated Seats (driver’s and passenger’s)
For more information, see each of these features in the
Index.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it’s dark
outside. Be sure to keep the HUD image dim
and placed low in your field of view.If your vehicle has the HUD, it can display the
speedometer reading in English or metric. The current
radio station, CD number and/or track number or
tape may also be displayed and will appear as an image
focused out toward the front of your vehicle.
The HUD is capable of displaying English or French.
SeeDIC Controls and Displays on page 3-55to change
the display from English to metric.
The Head-Up Display also displays the following lights
and messages when they appear on the instrument
panel cluster:
•Turn Signal Indicators
•High-Beam Indicator
•Low-Fuel Warning Message
See each of these features in the Index for more
information.
The Head-Up Display also displays a CHECK GAGES
icon. The following messages could appear on the
instrument panel cluster when CHECK GAGES appears:
•Engine Coolant Temperature Warning
•Low Oil Pressure
•Charging System Indicator
•Low Brake Fluid Warning

To adjust the HUD so you can see it properly:
1. Start your engine and turn the dimmer knob to the
desired HUD image brightness.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer knob set. If you are facing a dark object or
a heavily shaded area, your HUD may anticipate
that you are entering a dark area and may begin
to dim.
2. Adjust the driver’s seat. If you change your seat
position, you may have to readjust your HUD.
3. Press the UP or DN buttons until the HUD image is
easy to see and then press the DN button until the
HUD image is as low as possible, but remains
in full view straight ahead near the front bumper.
The HUD image can only be adjusted up and down,
not side-to-side.
4. To turn the image off, turn the dimmer knob
counterclockwise until it stops.
If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using
the dimmer knob. Polarized sunglasses could make the
HUD image harder to see.When youfirst start the vehicle the display will show
BUICK and the Buick logo for a few seconds. If it is cold
outside, this display may stay on for up to a minute.
Clean the inside of the windshield as needed to remove
any dirt orfilm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you can’t see the HUD image,
check to see if one of the following conditions exist:
•The HUD unit is covered,
•the HUD dimmer knob is adjusted incorrectly,
•the HUD image is not adjusted to the proper height,
•ambient light (in the direction your vehicle is
facing) is low, or
•a fuse is blown. SeeFuses and Circuit Breakers on
page 5-86.
If you ever have to have your windshield replaced, be
sure to get one that is designed for the HUD or your
HUD image may look blurred and out of focus.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly–and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle also has a message center that works
along with the warning lights and gages. SeeMessage
Center on page 3-44.

If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-22.
Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or Check Engine Light in
Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or CHECK
ENGINE light comes on to indicate that there is a
problem and service is required. Malfunctions often will
be indicated by the system before any problem is
apparent. This may prevent more serious damage to United StatesCanada

your vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modifications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modifications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light doesn’t come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
•Light Flashing—Amisfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
•Light On Steady—An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis
and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
•Reducing vehicle speed.
•Avoiding hard accelerations.
•Avoiding steep uphill grades.
•If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stopsflashing and remains on steady, see“If
the Light Is On Steady”following.
If the light continues toflash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see“If
the Light Is On Steady”following. If the light is still
flashing, follow the previous steps, and drive the vehicle
to your dealer or qualified service center for service.

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your Tank on page 5-6. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine
may not run as efficiently as designed since small
amounts of air are sucked into the fuel line causing
misfire. The system can detect this. Adding fuel should
correct this condition. Make sure to install the fuel
cap properly. SeeFilling Your Tank on page 5-6.Itwill
take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check
the vehicle. Your dealer has the proper test equipment
and diagnostic tools tofix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.

Charging System Indicator Message
The charging system
battery symbol will come
on in the message
center when you turn on
the ignition as a check
to show you it is working.
It will remain on as long as the engine is not running.
It should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this indicator appears in the message
center could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off all your accessories, such as
the radio and air conditioner.
Low Oil Pressure Message
Your vehicle is equipped with a low oil pressure warning
message.
Your oil pressure message lets you know when you
may have a problem with your engine oil pressure.
When the engine is running and this message appears,
the engine oil level may be too low. There may also
be another problem causing low oil pressure.
