You'll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one. Be sure
to follow the instructions that came with the child
restraint. Secure the child in the child restraint when and
as the instructions say.
1. Because your vehicle has a front passenger air bag,
always move the seat as far back as it will go before
securing a forward
-facing child restraint. (See
ªSeatsº in the Index.)
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.6. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint.
You may find it helpful to use your knee to push down
on the child restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.

2. Gently pry the battery out of the transmitter. Do not
use the metal flanges to ªpop outº the battery.
3. Replace the battery.
4. Reassemble the transmitter. Make sure the halves are
snapped together tightly so water will not get in.
5. Check the transmitter operation. If needed, follow
the instructions on resynchronizing your
remote transmitter.
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.
Resynchronization
Your remote keyless entry system uses a continually
changing code for increased security. Normally, the
receiver in your vehicle will keep track of this
changing code.

Loss of synchronization will occur if the transmitter
is activated more than 256 times while out of range
of the vehicle.

Loss of synchronization will occur after the battery
replacement if the transmitter is immediately
activated more than 16 times while out of range of
the vehicle.
If your remote keyless entry transmitter has stopped
working, you may need to resynchronize the transmitter
to the vehicle receiver. To do this, press the LOCK and
UNLOCK buttons together and hold for at least seven
seconds or until the horn sounds if equipped with
Content the Theft
-Deterrent system. Check the
transmitter operation.

NOTE: While this mode provides increased security, it
can be a problem if your remote keyless entry
transmitter is damaged, lost or if it fails to operate for
any reason while the Content Theft
-Deterrent system is
armed. The Content Theft
-Deterrent system must be
disarmed for the engine to run while in Mode 2; your
key can no longer disarm the system.
If your vehicle is equipped with the optional dealer
installed OnStar

system, OnStar will not be able to
remotely unlock your vehicle if it has been programmed
to Mode 2.
Mode 3: Standard Arming and Disarming

The system will arm when you lock the doors using
either power door lock switch while any door or the
liftgate is open and the key is removed from
the ignition.

The system will arm when you lock the doors with
your key or remote keyless entry transmitter and the
key is removed from the ignition.

The system will disarm when you unlock the doors
with your key or remote keyless entry transmitter.
Vehicles are delivered programmed in Mode 1.To change the mode:
1. Follow the instructions for ªEntering Programming
Modeº listed previously.
2. Insert your second key fully into any door key
cylinder and turn it to the unlock position.
This step is necessary to prevent accidental
programming of this feature to Mode 2. Do not
program this feature to Mode 2 without first reading
the special note contained in the description for that
mode. The door key cylinder must remain in the
unlock position during Steps 2 through 4.
3. Press the horn symbol on the remote keyless
entry transmitter.
4. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is in.
You can change the mode by pressing the horn
symbol on the remote keyless entry
transmitter again.

Sliding Door Security Lock
Your vehicle is equipped with a sliding door security
lock that helps prevent young children or other
passengers from opening the sliding door by using the
inside door handle.The security lock lever is located on the inside of the
sliding door, on the front edge of the door. To access the
lever, open the sliding door. Use the security lock label on
the edge of the door as a guide. This lock is on both doors
if your vehicle is equipped with dual sliding doors.
To use the security lock,
move the security lock lever
all the way up and close the
door from the outside.
If your vehicle is equipped with a power sliding door,
you can override the security lock by pressing either
