Once you have the top strap anchored, you'll be ready to
secure the child restraint itself. Tighten the top strap
when and as the child restraint manufacturer's
instructions say.
Anchor brackets for the rear seat positions are located
on the floor in the cargo area of your vehicle. Do not
use the rear tie
-down brackets near the liftgate for top
strap tethers.
Lower Anchorages and Top Tethers for
Children (LATCH System)
Your vehicle may have the LATCH system. If it does,
you'll find anchors (A) in the rear outside seat positions.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the LATCH
system will have two metal tabs where the seat cushion
meets the seatback.

1-46
With this system, use the LATCH system instead of the
vehicle's safety belts to secure a child restraint.
CAUTION:
If a LATCH-type child restraint isn't attached to
its anchorage points, the restraint won't be able
to protect a child sitting there. In a crash, the
child could be seriously injured or killed. Make
sure that a LATCH
-type child restraint is
properly installed using the anchorage points, or
use the vehicle's safety belts to secure the
restraint. See ªSecuring a Child Restraint in a
Rear Outside Seat Positionº in the Index for
information on how to secure a child restraint in
your vehicle using the vehicle's safety belts.

Securing a Child Restraint Designed for the
LATCH System
1. Find the anchors for the seating position you want to
use, where the bottom of the seatback meets the back
of the seat cushion.
2. Put the child restraint on the seat.
3. Attach the anchor points on the child restraint to the
anchors in the vehicle. The child restraint
instructions will show you how.
4. If the child restraint is forward
-facing, attach the top
strap to the top strap anchor. See ªTop Strapº in the
Index. Tighten the top strap according to the child
restraint instructions.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
strap from the top tether anchor and then disconnect the
anchor points.
Securing a Child Restraint in a Rear
Outside Seat Position
If your child restraint is equipped with the LATCH
system, see ªLower Anchorages and Top Tethers for
Children (LATCH)º in the Index.
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. Put the restraint on the seat.
2. 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.

1-49
5. To tighten the belt, feed the shoulder belt back into
the retractor 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.

The restraints won't work properly.
Securing a Child Restraint in the Right
Front Seat Position

1-51
If your child restraint is equipped with the LATCH
system, see ªLower Anchorages and Top Tethers for
Children (LATCH)º in the Index.
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. 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.
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.

1-53
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.

3. You are now ready to program the automatic door
locks. Select one of the four programming options
listed above, and press the unlock side of the power
door lock switch to cycle through the unlocking
options. You will have 30 seconds to begin
programming. If you exceed the 30 second limit, 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, 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 locks 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 auto lock/unlock setting will not
be modified.
See your dealer for more information.
Rear Door Security Locks
With this feature, you can lock the rear doors so they
can't be opened from the inside by passengers. To use
one of these locks do the following:
1. Open one of the rear doors.
2. You will find a security
lock lever located on the
inside edge of each rear
door. Move the lever
down to engage the
safety lock. Move the
lever up to disengage
the safety lock.
3. Close the door.
4. Do the same thing to the other rear door.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and open the door from the outside.
