Remote Vehicle Start
This feature allows you to start the engine from outside
the vehicle.
Laws in some local 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.
/(Remote Vehicle Start):If your vehicle has the
remote vehicle start feature, the remote keyless entry
transmitter will have a button with this symbol on it.
An increased range of operation is provided with the
remote keyless entry transmitter that has the remote
vehicle start button. The vehicle can be started from
approximately 180 feet (60 m) away. However, the
operating range may be less while the engine is running
and you will need to be closer to your vehicle to turn
it off than you were to turn it on.
Do not use the remote start feature if your vehicle is
low on fuel. Your vehicle may run out of fuel.To start the engine using the remote start feature, do the
following:
1. Aim the remote keyless entry transmitter, equipped
with the remote vehicle start button, at the vehicle.
2. Press and release the transmitter’s lock button, then
immediately press and hold the remote vehicle start
button until the vehicle’s turn signal lamps ash,
or for at least two seconds, if the vehicle’s lights are
not visible. The vehicle’s doors will be locked.
3. When the vehicle’s engine starts, the parking lamps
will turn on and remain on while the engine is
running.
After a remote start, the engine will automatically shut
off after 10 minutes unless a time extension has
been done or the vehicle’s key is inserted into the
ignition switch and turned to RUN.
The maximum number of remote starts or remote start
attempts between ignition cycles with the key is two.
If it is the vehicle’s rst remote start, and the engine is
still running, repeat Steps 1 and 2 for a 10 minute
time extension. Ten minutes will be added to the
remaining minutes of the rst remote start. The
10 minute time extension is considered a second
remote start.
2-8

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.
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 5-87.
It is possible for the PASS-Key
®III decoder to learn
the transponder value of a new or replacement key.
Up to 10 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.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder 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.

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 a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine
still will not start, or starts briey 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 do not, your engine
might not perform properly.Engine Coolant Heater
Your vehicle may have an engine coolant heater. 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. Your vehicle may also have
an internal thermostat in the plug end of the cord.
This will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C) as
noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine compartment.
3. Plug it into a normal, grounded 110-volt AC outlet.

Rear Air Outlets
The outlet behind the left rear seat is the cold air
return outlet. Be sure to keep it free from obstructions.
Also, keep the area around the base of the center
instrument panel console, between and under the front
seats, free of objects that could also obstruct airow
to the rear seating area.
For more information on how to use the main climate
control system, seeDual Climate Control System
on page 3-25. For information on ventilation, see
Outlet Adjustment on page 3-28.
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 briey 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.

Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
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 light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.

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.
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.
3-40

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.
Oil Pressure Light
If you have low engine oil
pressure, this light will stay
on after you start your
engine, or come on when
you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it xed immediately by
your GM dealer.
3-42

The oil light could also come on in three other situations:
When the ignition is on but the engine is not
running, the light will come on as a test to show you
it is working. The light will go out when you turn
the ignition on. If it does not come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it xed right away.
If you are idling at a stop sign, the light may blink
on and then off.
If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
