Attach the tether strap only to the
appropriate tether anchor as shown. The
tether strap may not work properly if
attached somewhere other than the
correct tether anchor.

If you install a child restraint with rigid
LATCH attachments, do not tighten the
tether strap enough to lift the child
restraint off the vehicle seat cushion when
the child is seated in it. Keep the tether
strap just snug without lifting the front of
the child restraint. Keeping the child
restraint just touching the vehicle seat
gives the best protection in a severe crash.

Once the child safety seat has been
installed using either the seatbelt, the
lower anchors of the LATCH system, or
both, you can attach the top tether strap.

Attachment (Regular Cab)

Note: For vehicles with adjustable head
restraints, route the tether strap under the
head restraint and between the head
restraint posts, otherwise route the tether
strap over the top of the seatback.

1.

Route the child safety seat tether strap
over the back of the seat and under the
head restraint.

2. Locate the correct anchor for the

selected seating position. You may
need to pull the seatback forward to
access the tether anchors. Make sure
the seat is locked in the upright position
before installing the child restraint.

3. Clip the tether strap to the anchor.

4. Tighten the child safety seat tether

strap according to the manufacturer's
instructions.

If the tether strap is clipped incorrectly, the
child safety seat may not be retained
properly in the event of a crash.

If the safety seat is not anchored properly,
the risk of a child being injured in a crash
greatly increases.

If your child restraint system has a tether
strap, and the child restraint manufacturer
recommends its use, we also recommend
its use.

Rear Seat Tether Strap
Attachment (Crew Cab and Super
Cab)

E167009

There are three loops of webbing just
above the back of the rear seat (along the
bottom edge of the rear window). Use
these loops as both routing loops and
anchor loops for up to three child safety
seat tether straps.

For example, you can use the center loop
as a routing loop for a child safety seat in
the center rear seat and as an anchoring
loop for child restraints installed in the
outboard rear seats.

Many tether straps cannot be tightened if
the tether strap is hooked to the loop
directly behind the child restraint. To
provide a tight tether strap:

E162714

1.

Route the tether strap under the head
restraint and through the loop directly
behind the child restraint.

E162715

2. Route the tether strap behind the head

restraint supports to a loop behind an
adjacent seating position, and hook the
strap hook onto the loop. If using the
driver side, pass the strap behind the
shoulder belt for the center seat.
Always put the tether strap through the
routing loop. The head restraint
support post will hold the child
restraint tightly, but the head restraint
post is not strong enough to hold the
child restraint during a crash.

3. Tighten the tether strap according to

the child restraint manufacturer's
instructions.

If the safety seat is not anchored properly,
the risk of a child being injured in a crash
greatly increases.

If your child restraint system has a tether
strap, and the child restraint manufacturer
recommends its use, we also recommend
its use.

BOOSTER SEATS

WARNING

Never place, or allow a child to place,
the shoulder belt under a child's arm
or behind the back because it

reduces the protection for the upper part
of the body and may increase the risk of
injury or death in a crash.

Note: Some booster seat safety belt guides
may not accommodate the shoulder portion
of the inflatable safety belt.

Use a belt-positioning booster seat for
children who have outgrown or no longer
properly fit in a child safety seat (generally
children who are less than 4 feet 9 inches
(1.45 meters) tall, are greater than age four
(4) and less than age twelve (12), and
between 40 pounds (18 kilograms) and
80 pounds (36 kilograms) and upward to
100 pounds (45 kilograms) if
recommended by your child restraint
manufacturer). Many state and provincial
laws require that children use approved
booster seats until they reach age eight, a
height of 4 feet 9 inches (1.45 meters) tall,
or 80 pounds (36 kilograms).

Booster seats should be used until you can
answer YES to ALL of these questions
when seated without a booster seat:

E142595

•

Can the child sit all the way back
against their vehicle seat back with
knees bent comfortably at the edge of
the seat cushion?

•

Can the child sit without slouching?

•

Does the lap belt rest low across the
hips?

•

Is the shoulder belt centered on the
shoulder and chest?

•

Can the child stay seated like this for
the whole trip?

Always use booster seats in conjunction
with your vehicle lap and shoulder belt.

Types of Booster Seats

E68924

•

Backless booster seats

If your backless booster seat has a
removable shield, remove the shield. If a
vehicle seating position has a low seat
back or no head restraint, a backless
booster seat may place your child's head
(as measured at the tops of the ears)
above the top of the seat. In this case,
move the backless booster to another
seating position with a higher seat back or
head restraint and lap and shoulder belts,
or consider using a high back booster seat.

E70710

•

High back booster seats

If, with a backless booster seat, you cannot
find a seating position that adequately
supports your child's head, a high back
booster seat would be a better choice.

Children and booster seats vary in size and
shape. Choose a booster that keeps the
lap belt low and snug across the hips,
never up across the stomach, and lets you
adjust the shoulder belt to cross the chest
and rest snugly near the center of the
shoulder. The following drawings compare
the ideal fit (center) to a shoulder belt
uncomfortably close to the neck and a
shoulder belt that could slip off the
shoulder. The drawings also show how the
lap belt should be low and snug across the
child's hips.
