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.
Theft-Deterrent System
Your vehicle may have a theft-deterrent system.
The theft-deterrent system will not arm when you lock
the doors using the key or the manual door lock. It arms
only when you use the remote keyless entry transmitter.
Arming the System
To arm the system, do the following:
1. Close the doors, the windows, the hood, and the
trunk or liftgate.
Ensure that the windows are closed, as the system
can be armed even if the windows are open.
2. Turn the key to LOCK and remove the key from the
ignition.
If the key is inserted in the ignition, the transmitter
will not arm the theft-deterrent system.3. Lock the doors by pressing the lock button on the
remote keyless entry transmitter.
•The LED light on the transmitter will flash once.
•All of the doors will lock.
•The hazard warning lamps will flash once and
the horn will chirp.
•The security light (A) will flash once every
second to indicate that the theft-deterrent system
is armed. The security light is located on the
secondary information center (SIC) on the center
of the instrument panel.

Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine.
The immobilizer system isolates the power supply to the
ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key
is turned to LOCK and removed from the ignition.
The security light located on the top center of the
instrument panel in the secondary information center will
flash when the immobilizer is active. If the light does
not flash after removing the key, have the system
checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
2-16

When trying to start the vehicle, if the engine does not
start and the security light continues flashing, 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 key. At this time, you may
also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-77. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty.
See your dealer who can have a new key made.
Up to five keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer can
have new keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside Assistance.

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:
Do not drive at any one speed, fast or slow,
for the rst 500 miles (805 km). Do not make
full-throttle starts.
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 4-35for more information.

{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as
fast as the vehicle goes. If you have to stop or
turn quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.

Adding Coolant
If the level falls below the MIN (B) mark, add the proper
coolant mixtureat the surge tank,but only when the
engine is cool. If the surge tank is empty, a special
fill procedure is necessary. SeeCooling System
on page 5-26for instructions on “How to Add Coolant
to the Coolant Surge Tank.”
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-23.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned. Stop
your engine if it overheats, and get out of
the vehicle until the engine is cool.
