Your vehicle has one
double-sided key for the
ignition and all door locks.
If you ever lose your keys, your dealer will be able to
assist you with obtaining new ones.
I NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your key inside.
You may even have to damage
your vehicle to get in.
So be sure you have an
extra key.
Tailgate
You can open the tailgate by lifting up on its handle
while pulling the tailgate toward you.
TO shut the tailgate, firmly push it away from you into
the latch.
After you put the tailgate back up, pull it back toward
you, to be sure that it latches securely.
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 finish damage.

Door Locks
A CAUTION:
Unlocked doors can be dangerous.
Passengers
-- especially children -- can easily
open the doors and fall out. When a door
is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may
not be so obvious: You increase the
chance of being thrown out of the vehicle in
a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you will be far
better
off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
From the outside, use your key or
the Keyless Entry
System,
if your vehicle has this option.
To lock the door from the
inside, slide the lever
on
your door down.
To unlock the door, slide the lever up.

Zear Door Security Locks (Crew Cab)
With this feature, you can
lock the rear doors
so they
can’t be opened from the

Keyless Entry System (If Equipped)
If your vehicle has this option, you can lock and unlock
your doors from about
3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
In addition, your interior lamps will be illuminated for a
set period of time when the transmitter signal is received
by the Keyless Entry System.
Your Keyless Entry System operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and
with Industry Canada.
This device complies with
Part 15 of the FCC Rules.
Operation
is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with
RSS-210 of Industry
Canada. Operation
is subject to the following two
conditions:
(1) this device may not cause interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation of the device. This
system has
a range of about 3 feet (1 m) up to
30 feet (9 m). 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 to determine if battery replacement or
transmitter resynchronization is necessary. See the
instructions
that follow.
Check the distance. You may be too far from your
vehicle.
You may need to stand closer during rainy
or snowy weather.
0 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.
0 If you’re still having trouble, see your GM dealer or
a qualified technician for service.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.

Operation Battery Replacement
To unlock the driver’s door, press the UNLOCK
button.
If you press this button again within five seconds, all the
remaining doors (except the third door)
will unlock. The
interior lamps will come on for
40 seconds or until the
ignition is turned on.
Press the LOCK button to lock all the doors (except the
third door). The interior lamps will come on for two
seconds as soon as all the doors are closed.
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. 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.
Use one three volt, type CR2032, or equivalent battery.

To replace the battery: Synchronization
1. Insert a small coin, or flathead screwdriver, to
separate the bottom of the transmitter from
the top.
making sure the positive
(+) side of the battery is
facing down.
2. Remove the battery and replace it with a new one,
3. Snap the top and bottom together.
4. Test the operation of the transmitter with your
vehicle.
If the transmitter does not work, try
synchronizing the transmitter
with the receiver. Synchronization
may be necessary due to the security
method used
by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the
LOCK
and UNLOCK buttons on the transmitter for at least
five seconds. The door locks should cycle to confirm
synchronization.
If the locks do not cycle, see your
dealer for service.
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 tone 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. And
remember to lock the doors.
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.
Lock all the doors except the driver’s.
New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” 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 first
500 miles (805 km).
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
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.
0 Don’t tow a trailer during break-in. See
“Towing a Trailer’’ in the Index for
more information.
a Avoid making hard stops for the first
