3-52 Seats and Restraints
{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 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.
The vehicle is equipped with a front
center airbag in the inboard side of
the driver seat. Even with a front
center airbag, a child restraint can
be installed in any second row
seating position.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint on
page 3-46. 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.
1. Attach and tighten the lower
attachments to the lower
anchors. If the child restraint
does not have lower
attachments or the desired
seating position does not have
lower anchors, secure the child
restraint with the safety belts
and top tether when
recommended by the child
restraint manufacturer. Refer to
your child restraint manufacturer
instructions and the instructions
in this manual.
1.1. Find the lower anchors for the desired seating
position.

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.If the position you are using
has a fixed head restraint
and you are using a single
tether, route the tether
around the inboard or
outboard side of the head
restraint.
If the position you are using
has a fixed or an adjustable
head restraint and you are
using a dual tether, route
the tether around the head
restraint.
3. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
LATCH path and attempt to move it side to side and back
and forth. There should be no
more than 2.5 cm (1 in) of
movement, for proper
installation.
Head Restraint Removal and
Reinstallation
1. Partially fold the seatback
forward. See Third Row Seats
on page 3-14 for additional

88 km/h (55 mph) or less for
the first 805 km (500 mi).
.Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
.Avoid making hard stops for
the first 322 km (200 mi) or
so. During this time the new

broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this
breaking-in guideline every
time you get new brake
linings.
.Do not tow a trailer during
break-in. SeeTrailer Towing
on page 9-73 for the trailer
towing capabilities of the
vehicle and more information.
