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.

If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the
interior lights will come on. Pressing UNLOCK again
within three seconds will cause the remaining doors to
unlock. The parking lamps will flash and the interior
lights will come on.
LOCK: Pressing this button once will lock all of the
doors. Press LOCK again within three seconds and the
horn will chirp.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.
Remote Panic Alarm
When the button with the horn symbol on the key
transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting the vehicle.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to prevent
another transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be purchased
through your dealer. Remember to bring any remaining
transmitters with you when you go to your dealer. When the
dealer matches the replacement transmitter to your vehicle,
any remaining transmitters must also be matched. Once your
dealer has coded the new transmitter, the lost transmitter will
not unlock your vehicle. Each vehicle can have only four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't work
at the normal range in any location. If you have to get close to
your vehicle before the transmitter works, it's probably time
to change the battery.
NOTICE:
When replacing the battery, use care not to touch any
of the circuitry. Static from your body transferred to
these surfaces may damage the transmitter.

2-9 Tailgate Removal
The tailgate on your vehicle can be removed to allow for
different loading situations. Although the tailgate can be
removed without assistance, you may want someone to
assist you with the removal to avoid possible damage to
the vehicle.
To remove the tailgate:
1. Remove the theft
deterrent bracket
from the lower
tailgate hinge,
located on the
passenger's side
of the vehicle.
Rotate the bolt
counterclockwise
to remove.
2. Raise the tailgate
slightly and release
both retaining cable
clips. To release the
retaining cable clips, lift
the cable so it points
straight out and push the
cable clip forward.
3. With the tailgate at a
slight upward angle, pull
back on the tailgate at
the right edge and then
move the tailgate to
the right to release
the left edge.

4. After removing the tailgate, reinstall the theft
deterrent bracket bolt. The bracket does not need to
be in place to install the bolt.
Reverse the above procedure to reinstall. Make sure the
tailgate is secure.
Theft
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.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have an automatic transmission, taking
your key out also locks your transmission. Also
remember to lock the doors.If the key is in the ignition, with any door open, and you
try to lock your doors with the power door locks, the
driver's door will not stay locked. This will help to keep
you from locking your keys in the vehicle.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.

Valuables can be locked in the center floor console.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.

Content Theft-Deterrent
(If Equipped)
Your vehicle may be equipped with a Content
Theft
-Deterrent alarm system.
With this system, the
SECURITY message will
flash as you open the door
(if your ignition is off).
This light 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
message should come on and stay on. If using the
remote keyless entry transmitter, the door does not
need to be open.
3. Close all doors. The SECURITY message should go
off after approximately 15 seconds. The alarm is not
armed until the SECURITY message 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 flash 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 after the 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.
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.

2-12 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 message 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 flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables 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 message flashes,
wait until the light stops flashing 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 message
comes on, you will be able to restart the engine if you turn
the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock at this time. You
may also want to check the fuse (see ªFuses and Circuit
Breakersº in the Index). See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.

NOTICE:
Damage to your transmission caused by shifting
out of PARK (P) or NEUTRAL (N) with the
engine racing isn't covered by your warranty.
DRIVE (D): This position is for normal driving. If you
need more power for passing, and you're:

Going less than about 35 mph (56 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
DRIVE (D) can be used when towing a trailer, carrying
a heavy load, driving on steep hills or for off
-road
driving. You may want to shift the transmission to
THIRD (3) or, if necessary, a lower gear selection if the
transmission shifts too often.THIRD (3): This position is also used for normal
driving, however it offers more power and lower fuel
economy than DRIVE (D).
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
If you manually select SECOND (2) in a light duty
automatic transmission, the transmission will drive in
second gear. You may use this feature for reducing the
speed of the rear wheels when you are trying to start
your vehicle from a stop on slippery road surfaces.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever is put in FIRST (1) while the vehicle is
moving forward, the transmission won't shift into first
gear until the vehicle is going slowly enough.

Shift Light
If you have a manual
transmission, you may have
a SHIFT light. This light
will show you when to shift
to the next higher gear for
best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions allow.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go
on and off if you quickly change the position of
the accelerator.
If your vehicle has four
-wheel drive and is equipped
with a manual transmission, disregard the SHIFT light
when the transfer case is in 4
-Wheel Low.
Ignore the SHIFT light when you downshift.
Four-Wheel Drive (If Equipped)
If your vehicle has four-wheel drive, you can send your
engine's driving power to all four wheels for extra
traction. To get the most satisfaction out of four
-wheel
drive, you must be familiar with its operation. Read the
part that follows before using four
-wheel drive. See the
appropriate text for the transfer case in your vehicle.
NOTICE:
Driving in the 4-WHEEL HIGH (4H) or
4
-WHEEL LOW (4L) positions for a long time
on dry or wet pavement could shorten the life of
your vehicle's drivetrain.
Front Axle Locking Feature
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock is normal.

yellowblue
2-28 Manual Transfer Case (If Equipped)
The transfer case shift lever is on the floor to the right of
the driver. Use this lever to shift into and out of
four
-wheel drive.
The 4WD indicator will
light up when you shift into
four
-wheel drive and the
front axle engages.Some delay between shifting and the indicator's lighting
is normal.
An indicator on the bezel near the lever shows you the
transfer case settings:
2
-Wheel High (2H): This setting is used for driving in
most street and highway situations. Your front axle is
not engaged in two
-wheel drive. This setting also
provides the best fuel economy.
4
-Wheel High (4H): Use 4HI when you need extra
traction, such as 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.

yellowblue
2-30 Automatic Transfer Case (If Equipped)
The transfer case switches
are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of
four
-wheel drive.
You can choose among four driving settings:
2HI: This setting is used for driving in most street and
highway situations. Your front axle is not engaged in
two
-wheel drive. This setting also provides the best fuel
economy.
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent only to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.

yellowblue
2-31
4HI: Use 4HI when you need extra traction, such as 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.
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 ªRecreational
Vehicle Towingº or ªTowing Your Vehicleº in the Index
for more information.Indicator lights in the switches show which setting you
are in. The indicator lights will come on briefly 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 flash
while shifting the transfer case. 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 ªService
4WDº in the Index for further information.
Shifting to 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 flash while shifting. It
will remain illuminated when the shift is completed.
Shifting to 2HI
Press and release the 2HI switch. This can be done at
any speed (except when shifting from 4LO).
