Programmable Unlocking Feature
The following is the list of available programming
options:
Mode 1:Driver's door unlocks when the transmission is
shifted into PARK (P)(automatic transmission vehicles
only).
Mode 2:All doors unlock when the transmission is
shifted into PARK (P)(automatic transmission vehicles
only). This is the mode that is pre-programmed in
the factory for your vehicle.
Mode 3:All doors unlock when the key is removed
from the ignition This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
Mode 4:No automatic door unlock.
The following instructions tell you how to change the
automatic door unlock mode. Choose one of the
four programming options listed above before entering
the program mode. To enter the program mode, do
the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.2. Turn the key to RUN and LOCK twice. Then, with
the key in LOCK, release the turn
signal/multifunction lever. Once you do this, the
doors will lock and unlock, the horn will chirp twice,
and a 30-second timer will begin. You are now
ready to program the automatic door unlock feature.
3. Press the door unlock switch once. You will hear
one, two, three, or four chimes. The number of
chimes tells you which unlock mode is currently
selected. Continue to press the door unlock switch
until the number of chimes that you hear matches the
number of the mode that you want. If you take longer
than 30 seconds, the locks will automatically lock and
unlock and the horn will chirp twice to indicate that
you have left the program mode. If this occurs, you
can repeat the procedure beginning with Step 1 to
re-enter the programming mode.
You can exit the program mode any time by turning the
ignition to RUN (the doors will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode). If the lock/unlock
switches are not pressed while in the programming
mode, the current automatic settings will not be
modi®ed.

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. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
With this system, the
security light will ¯ash as
you open the door (if your
ignition is off), to let you
know that you are
activating the system.
This message reminds you to activate the theft-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The security light
should come on and ¯ash. If using the remote
keyless entry transmitter, the door does not need to
be open.If the delayed locking feature is active, the alarm
will not be activated until all doors are closed
and the security light goes off.
3. Close all doors. The security light will stop ¯ashing
and stay solid. The light should go off after
approximately 30 seconds. The alarm is not armed
until the security light goes off.
If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle's headlamps will ¯ash and the horn will sound for
about two minutes, then will turn off to save the
battery power.
Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here's how to avoid setting off the alarm by accident:
·If you don't want to activate the theft-deterrent
system, the vehicle should be locked with the door
key
afterthe doors are closed.
·Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm if the system
has been armed.
2-18

If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter or
by placing the key in the ignition and turning it to
START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps ¯ash, check to see if the horn
works. The horn fuse may be blown. To replace
the fuse, see
Fuses and Circuit Breakers on page 5-110.
If the alarm does not sound or the vehicle's headlamps
do not ¯ash, the vehicle should be serviced by an
authorized service center.
Passlockž
Your vehicle is equipped with the
Passlockžtheft-deterrent system.
Passlock
žis a passive theft-deterrent system.
Passlockženables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light ¯ashes,
wait until the light stops ¯ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
žsystem is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
žat this
time. You may also want to check the fuse (see
Fuses and Circuit Breakers on page 5-110.) See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-5under Customer Assistance Information.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle doesn't need an elaborate
ªbreak-in.º But it will perform better in the long run
if you follow these guidelines:
·Keep your speed at 55 mph (88 km/h) or less for
the ®rst 500 miles (805 km).
·Don't drive at any one speed Ð fast or slow Ð
for the ®rst 500 miles (805 km). Don't make
full-throttle starts.
·Avoid making hard stops for the ®rst 200 miles
(322 km) or so. During this time your new
brake linings aren't 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.
·Don't tow a trailer during break-in. See ªTowing
a Trailerº in the Index for more information.
Ignition Positions
With the key in the ignition switch, you can turn it to
four different positions.
A (LOCK):This position locks your ignition and manual
transmission. It's a theft-deterrent feature. You will
only be able to remove your key when the ignition is
turned to LOCK.
B (ACCESSORY):This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is off.
2-20

{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to OFF. Don't press the key
release button while the vehicle is moving.
Notice:If your key seems stuck in LOCK and you
can't turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
C (RUN):This is the position for driving.
D (START):This position starts your engine.
Key Release Button (Manual
Transmission)
The ignition key cannot be
removed from the ignition
of manual transmission
vehicles unless the
key release button is used.
To remove the key on manual transmission vehicles,
turn the key to ACC, then press the button and turn the
key to LOCK. Do not hold the button in while turning
the key to ACC. Pull the key straight out.
2-21

Retained Accessory Power (RAP)
Your vehicle may be equipped with a Retained
Accessory Power (RAP) feature which will allow certain
features on your vehicle to continue to work up to
10 minutes after the ignition key is turned to OFF.
Your radio, power windows and overhead console will
work when the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to LOCK, these
features will continue to work for up to 10 minutes or
until a door is opened.
Starting Your Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position ± that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only. If you have a diesel engine refer
to the diesel supplement for starting procedure.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the ¯oor
and start the engine. Your vehicle won't start if the clutch
pedal is not all the way down ± that's a safety feature.
2-22

Starting Your V8 Engine
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
your 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 it doesn't start within 10 seconds, push the
accelerator pedal all the way to the ¯oor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.When starting your engine in very cold weather (below
0ÉF or-18ÉC), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of the
key.
2. If your engine still won't 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. When the engine
starts, let go of the key and accelerator. If the
vehicle starts brie¯y but then stops again, do the
same thing, but this time keep the pedal down
for ®ve or six seconds. This clears the extra
gasoline from the engine.
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.
2-23

G(4HI):Use 4HI when you need extra traction, such
a on snowy or icy roads or in most off-road situations.
This setting also engages your front axle to help
drive your vehicle. This is the best setting to use when
plowing snow.
g(4LO):This setting also engages your front axle
and delivers extra torque. You may never need 4LO. It
sends maximum power to all four wheels. You might
choose 4LO if you are driving off-road in deep
sand, deep mud, deep snow and climbing or descending
steep hills.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See ªParking Brakeº in the
Index.NEUTRAL:Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-55orTowing
Your Vehicle on page 4-55for more information.
Indicator lights in the switches show which setting your
transfer case is in. The indicator lights will come on
brie¯y when you turn on the ignition and one will stay on.
If the lights do not come on, you should take your
vehicle to your dealer for service. An indicator light will
¯ash while the transfer case is being shifted. It will
remain illuminated when the shift is complete. If
for some reason the transfer case cannot make a
requested shift, it will return to the last chosen setting.
If the SERVICE 4WD light stays on, you should take
your vehicle to your dealer for service. See
Service on
page 5-3for further information.
Shifting into 4HI or AUTO 4WD
Press and release the 4HI or AUTO 4WD switch. This
can be done at any speed (except when shifting
from 4LO), and the indicator light will ¯ash while shifting.
It will remain illuminated when the shift is completed.
