Regular Cab
For regular cab models, the top
tether anchors are under covers on
the back panel behind the
passenger seat. Remove the trim
plug to access the anchor. Be sure
to use an anchor on the same side
of the vehicle as the seating
position where the child restraint will
be placed.Crew Cab Shown, Double Cab Similar
For crew and double cab models,
the top tether anchors are the loops
near the top of the seatback for
each rear seating position. These
loops will be used to route the top
tether through, as well as to secure
the top tether to the vehicle. Be sure
to use the anchor (loop) on the
same side of the vehicle as the
seating position where the child
restraint will be placed.
Be sure to read the following
instructions to properly install a child
restraint using these loops. Do not secure a child restraint in a
position without a top tether anchor
if a national or local law requires
that the top tether be attached, or if
the instructions that come with the
child restraint say that the top tether
must be attached.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position. See
Where to Put the
Restraint 092 for additional
information.
Securing a Child Restraint
Designed for the LATCH
System
{Warning
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured or
killed. Install a LATCH-type child

Warning (Continued)
restraint properly using the
anchors, or use the vehicle's
safety belts to secure the
restraint, following the instructions
that came with the child restraint
and the instructions in this
manual.
{Warning
Do not attach more than one child
restraint to a single anchor,
except for the center top tether
anchors in the crew and double
cabs. Attaching more than one
child restraint to a single anchor
could cause the anchor or
attachment to come loose or even
break during a crash. A child or
others could be injured. To reduce
the risk of serious or fatal injuries
during a crash, attach only one
child restraint per anchor.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.
Caution
Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the rear seatback
when the seat is occupied. Do not
fold the empty rear seat with a
safety belt buckled. This could
damage the safety belt or the
seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 092.
This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts.
Instead use the vehicle's anchors
and child restraint attachments to

secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.
Regular Cab Models1. For models without a rear seat, forward-facing child restraints
should only be installed in the
right front seating position with
safety belts and a top tether.
See Securing Child Restraints
(Center Front Seat) 0105 or
Securing Child Restraints
(Rear Seat) 0105 orSecuring

If the child restraint
manufacturer recommends that
the top tether be attached,
attach and tighten the top
tether to the top tether anchor,
if your vehicle has one. Refer

1.1. Fold the passenger seatback forward to
access the top tether
anchor. See Reclining

1.4. Route, attach, and tighten the top tether according to
your child restraint

following instructions:
If the position you are
using has an adjustable
head restraint and you are
using a dual tether, route
the tether around the head
restraint.
If the position you are
using has an adjustable
head restraint and you are
using a single tether, raise
the head restraint and
route the tether under the
head restraint and in
between the head
restraint posts.
2. Secure the child restraint in the right front seating position with
the vehicle safety belts. See
Securing Child Restraints
(Center Front Seat) 0105 or
