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 is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be opened from approximately 3 feet (1 m)
up to 60 feet (18 m) away with the remote keyless
entry transmitter.
If your vehicle has the remote vehicle start feature, you
can also start the vehicle’s engine with the remote
keyless entry transmitter.

2. Remove the old battery and replace it with the new
one. Make sure the positive side (+) of the battery
faces up. Use one three-volt, CR2032 battery,
or equivalent type.
3. Put the two halves back together. Make sure the
cover is on tight so water will not get inside the
transmitter.
4. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active, the climate control
system will heat or cool the inside of the vehicle based
on the outside temperature. The rear window defogger
will be turned on by the climate control system when it is
heating the inside of the vehicle. Normal operation of
the system will return after the key is turned to RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.
The remote start system needs to be reset after your
vehicle’s engine is started two times using the
transmitter’s remote start button. The remote start
system is reset by inserting the vehicle’s key into the
ignition switch and turning to RUN. SeeIgnition
Positions on page 2-22for information regarding the
ignition positions on your vehicle.
Your remote keyless entry transmitter with the
remote start button provides an increased range of
operation. You can start your vehicle from approximately
492 feet (150 m) away. However, the range may be
less while the vehicle is running, and as a result
you may need to be closer to your vehicle to turn it off
than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-3for additional information.

PASS-Key®III Operation
The vehicle is equipped
with PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III is a passive
theft-deterrent system.
This means nothing special
needs to be done to arm
or disarm the system.
It works when the key is
inserted or removed
from the ignition.
PASS-Key
®III uses a transponder in the ignition key
that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle’s starter and fuel systems. The starter will not
work and fuel will stop owing to the engine. If
someone tries to start the vehicle again with the wrong
key, the vehicle will not start. Anyone using a
trial-and-error method to start the vehicle will be
discouraged to do so because of the high number of
electrical key codes.When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED DUE TO THEFT
SYSTEM warning message on the Driver Information
Center (DIC) 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 5-112. If the engine still
does not start with the other key, the vehicle needs
service. If the vehicle does start, the rst key may be
faulty. See your dealer who can service the
PASS-Key
®III to have a new key made. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-6for more information.
It is possible for the PASS-Key
®III decoder to accept
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. If all
the programmed keys are lost or do not operate,
see your GM dealer or a locksmith who can service
PASS-Key
®III to have keys made and programmed to
the system.
Canadian Owners: If all the keys are lost or damaged,
only a GM dealer can service PASS-Key
®III to have
new keys made and programmed to the system.

Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
The 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.
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 the
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 the engine does not start within 10 seconds, hold
your key in START for about 10 seconds at a time
until the engine starts. Wait about 15 seconds
between each try.When your engine has run for 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 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. If the vehicle starts
briey but then stops again, do the same
thing. This time keep the pedal down for ve or
six seconds to clear the extra gasoline from
the engine. After waiting about 15 seconds, repeat
the normal starting procedure.
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.

When the ignition key is turned to RUN, the HUD will
display an introductory message for a short time,
until the HUD has warmed up.
The following indicator lights come on the instrument
panel when activated and will also appear on the HUD:
Turn Signal Indicators
High-Beam Indicator Symbol
The HUD will temporarily display CHECK TRIP
COMPUTER when there are messages on the DIC trip
computer.
The HUD will also display the following messages when
these systems, if equipped, are active:
TRACTION CONTROL ACTIVE
STABILITY CONTROL ACTIVE
The HUD will temporarily display the TRACTION
CONTROL OFF message when the traction control
system is turned off.
The HUD will temporarily display the CRUISE SET
message when cruise control is activated or cruise
speed is increased.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image as
a parking aid.When the HUD is on, the speedometer reading will
continually be displayed. The current radio station or
CD track number will display for a short period of time
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed.
The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn navigation
information are displayed on the HUD.
The HUD control is located
on the console.
To adjust the HUD image so that items are properly
displayed, do the following:
1. Adjust the driver’s seat to a comfortable position.
2. Start the engine.
3. Adjust the HUD controls.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on the vehicle. The pictures help to 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
the 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 the vehicle’s functions. As the details
show on the next few pages, some warning lights come
on briey when the engine is started just to indicate they
are 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 the vehicle’s functions. Often gages and
warning lights work together to indicate when there is a
problem with the vehicle.
When one of the warning lights comes on and stays on
while the vehicle is being driven, or when one of the
gages shows there may be a problem, check the section
that tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and
even dangerous. So please get to know the vehicle’s
warning lights and gages. They can be a big help.
The vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-52for
more information.

Malfunction Indicator Lamp
Check Engine Light
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 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 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 awhile, 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:Modications 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.
Modications 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. SeeAccessories
and Modifications on page 5-3.
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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. 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, misring, 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,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x 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 check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
