safety belt quickly if you ever had to.

5. To tighten the belt, pull up on the shoulder belt while
you push down on the child restraint. If you're using
a forward
-facing child restraint, you may find it
helpful to use your knee to push down on the child
restraint as you tighten the belt.
6. 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.

1-43 Securing a Child Restraint in the Center
Rear Seat Position
X±01±0105±T
You'll be using the lap belt. 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.
CAUTION:
A child in a child restraint in the center front seat
can be badly injured or killed by the right front
passenger air bag if it inflates even though your
vehicle has Next Generation frontal air bags.
Never secure a child restraint in the center front
seat. It's always better to secure a child restraint
in the rear seat. You may secure a forward
-facing
child restraint in the right front passenger seat,
but before you do, always move the front
passenger seat as far back as it will go. It's better
to secure the child restraint in a rear seat.
See the earlier part about the top strap if the child
restraint has one.

Securing a Child Restraint in the Right
Front Seat Position
X±01±0102±T
Your vehicle has a right front passenger air bag. Never
put a rear
-facing child restraint in this seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear
-facing child
restraint would be very close to the inflating air
bag. Always secure a rear
-facing child restraint
in the rear seat.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.
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 right 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.

6. To tighten the belt, feed the lap 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.
Larger Children
AV170105
Children who have outgrown child restraints should
wear the vehicle's safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap
-shoulder belt and
get the additional restraint a shoulder belt can provide.

2-15 Remote Trunk Release Lockout
The trunk release lockout
switch in the glove box
must be on for the TRUNK
button to work. This feature
allows you to secure items
in the trunk when you must
leave the ignition key with
an attendant.
To secure the trunk, turn off the TRUNK RELEASE
switch, lock the glove box, then take the door key with
you. Now the trunk button to the left of the steering
column will not open the trunk.
Trunk Security Override
The remote keyless entry transmitter (if equipped), will
open the trunk even if the trunk release lockout switch
is OFF.
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.
With the ignition off and the driver's door open, 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
and transaxle. 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.

yellowblue
2-16 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?

If possible, park in a busy, well lit area.

Put your valuables in a storage area, like your
trunk or glove box. Be sure to close and lock the
storage area.

Close all windows.

Turn off the TRUNK RELEASE lockout in the
glove box.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.
Universal Theft-Deterrent
(If Equipped)
If your vehicle has
this option, it has a
theft
-deterrent alarm
system. With this system,
the SECURITY light will
flash as you open the door
(if your ignition is off).
This light reminds you to activate the theft
-deterrent
system when leaving your vehicle.
Activating the system:
1. Open the door.
2. Lock the door with the power door lock switch while
the door is open, or with the remote keyless entry
transmitter. The SECURITY light should turn on and
stay on.
3. Close all doors. The SECURITY light should go off
after about 30 seconds. The alarm is not armed until
the SECURITY light goes off.

yellowblue
2-17
If the SECURITY light comes on for one minute and
then shuts off while the ignition is on, the security
system has detected a problem with itself. See your
dealer for service.
If a door or the trunk is opened without the key or remote
keyless entry transmitter, the alarm will go off. It will
also go off if the trunk lock is damaged. Your vehicle's
lamps will flash and the horn will sound for one minute,
and then will go off in order to save battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or manual door lock. It
activates only if you use a power door lock switch with
a door open, or 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. You must still shut off the alarm by inserting the key
in the door lock, or by pressing the UNLOCK button on
the remote keyless entry transmitter.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, lock the door by using the door key or the
manual door lock switch.

Always unlock a door with a key, or use the remote
keyless entry system transmitter. Unlocking a door
any other way will set off the alarm.If you set off the alarm by accident, unlock any door
with your key.
You can also turn off the alarm by pressing UNLOCK
on the remote keyless entry transmitter, if you have it.
The alarm won't stop if you try to unlock a door any
other way.
Testing the Alarm
1. From inside the vehicle, roll down the window.
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 car, 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 lamps 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 lamps do not
flash, the vehicle should be serviced by an authorized
service center.
