Crew Cab Split Bench Rear Seat: Center LATCH
Anchorages Available
If a child restraint installed in the center
position blocks the seat belt webbing or buckle
for the outboard position, do not use that
outboard position. If a child seat in the center
position blocks the outboard LATCH anchors or
seat belt, do not install a child seat in that
outboard position.
Always follow the directions of the child
restraint manufacturer when installing your
child restraint. Not all child restraint systems
will be installed as described here.
To Install A LATCH-Compatible Child
Restraint
If the selected seating position has a
Switchable Automatic Locking Retractor (ALR)
seat belt, stow the seat belt, following the
instructions below. See Ú page 364 to check
what type of seat belt each seating position has.
1. Loosen the adjusters on the lower straps
and on the tether strap of the child seat so
that you can more easily attach the hooks
or connectors to the vehicle anchorages.

2. Place the child seat between the lower anchorages for that seating position. If the
second row seat can be reclined, you may
recline the seat and/or raise the head
restraint (if adjustable) to get a better fit. If
the rear seat can be moved forward and
rearward in the vehicle, you may wish to
move it to its rear-most position to make
room for the child seat. You may also move
the front seat forward to allow more room
for the child seat.
3. Attach the lower hooks or connectors of the child restraint to the lower anchorages in
the selected seating position.
4. If the child restraint has a tether strap, connect it to the top tether anchorage. See
Úpage 366 for directions to attach a tether
anchor.
5. Tighten all of the straps as you push the child restraint rearward and downward into
the seat. Remove slack in the straps according to the child restraint
manufacturer’s instructions.
6. Test that the child restraint is installed tightly by pulling back and forth on the child
seat at the belt path. It should not move
more than 1 inch (25.4 mm) in any
direction.
How To Stow An Unused Switchable-ALR
(ALR) Seat Belt:
When using the LATCH attaching system to
install a child restraint, stow all ALR seat belts
that are not being used by other occupants or
being used to secure child restraints. An unused
belt could injure a child if they play with it and
accidentally lock the seat belt retractor. Before
installing a child restraint using the LATCH
system, buckle the seat belt behind the child
restraint and out of the child’s reach. If the
buckled seat belt interferes with the child
restraint installation, instead of buckling it
behind the child restraint, route the seat belt
through the child restraint belt path and then
buckle it. Do not lock the seat belt. Remind all
children in the vehicle that the seat belts are not
toys and that they should not play with them.WARNING!
Never use the same lower anchorage to
attach more than one child restraint

Installing Child Restraints Using The
Vehicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt. The seat belts in the passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) that is
designed to keep the lap portion of the seat belt
tight around the child restraint so that it is not
necessary to use a locking clip. The ALR
retractor can be “switched” into a locked mode
by pulling all of the webbing out of the retractor
and then letting the webbing retract back into
the retractor. If it is locked, the ALR will make a
clicking noise while the webbing is pulled back
into the retractor.See the “Automatic Locking Mode” description
Ú
page 341 for additional information on ALR.
Please see the table below and the following
sections for more information.

WARNING!
Improper installation of a child restraint to
the LATCH anchorages can lead to failure of
the restraint. The child could be badly
injured or killed. Follow the child restraint
manufacturer’s directions exactly when
installing an infant or child restraint.
Child restraint anchorages are designed to
withstand only those loads imposed by
correctly-fitted child restraints. Under no
circumstances are they to be used for adult
seat belts, harnesses, or for attaching other
items or equipment to the vehicle.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure
of the restraint. The child could be badly
injured or killed.

Installing A Child Restraint With A
Switchable Automatic Locking Retractor
(ALR):
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
1. Place the child seat in the center of the
seating position. If the second row seat can
be reclined, you may recline the seat and/
or raise the head restraint (if adjustable) to
get a better fit. If the rear seat can be
moved forward and rearward in the
vehicle, you may wish to move it to its
rear-most position to make room for the child seat. You may also move the front
seat forward to allow more room for the
child seat.

2. Pull enough of the seat belt webbing from the retractor to pass it through the belt path
of the child restraint. Do not twist the belt
webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat.
Frequently Asked Questions About Installing Child Restraints With Seat Belts

5. To lock the seat belt, pull down on the
shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to retract
back into the retractor. As the webbing
retracts, you will hear a clicking sound. This
means the seat belt is now in the Automatic
Locking mode.
6. Try to pull the webbing out of the retractor. If it is locked, you should not be able to pull
out any webbing. If the retractor is not

locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. If the child restraint has a top tether strap and the seating position has a top tether
anchorage, connect the tether strap to the
anchorage and tighten the tether strap
Úpage 366.
9. Test that the child restraint is installed tightly by pulling back and forth on the child
seat at the belt path. It should not move
more than 1 inch (25.4 mm) in any
direction. Any seat belt system will loosen with time, so
check the belt occasionally, and pull it tight if
necessary.
Installing Child Restraints Using The Top
Tether Anchorage
The top tether anchorages in this
vehicle are tether strap loops located
between the rear glass and the back
of the rear seat. There is a tether
strap loop located behind each seating position.
Follow the steps below to attach the tether strap
of the child restraint.
Right Or Left Outboard Seats:

1. Reach between the rear seat and rear glass to access the tether strap loop.

2. Place a child restraint on the seat and adjust the tether strap so that it will reach
over the seat back, through the space
between the head restraint and the seat
back, through the tether strap loop behind
the seat and over to the tether strap loop
behind the center seat.
WARNING!
Do not attach a tether strap for a rear-facing
car seat to any location in front of the car
seat, including the seat frame or a tether
anchorage. Only attach the tether strap of a
rear-facing car seat to the tether anchorage
that is approved for that seating position,
located behind the top of the vehicle seat.
See the section “Lower Anchors and Tethers
for CHildren (LATCH) Restraint System” for the
location of approved tether anchorages in
your vehicle.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying Passenger
Front Air Bag can cause death or serious
injury to a child 12 years or younger, including
a child in a rear-facing child restraint.
