This vehicle is provided with tether anchor-
ages for a top tether strap behind the
second row seats3 and the third row
seats4.
When using the third row observe the
following:

Installation of infant and child restraint
systems with a top tether strap is al-
lowed only on both third row seats plus
the center second row seat.


When using the center second row seat
for a top tether strap, the left third row
seat should only be used for a child re-
straint system, since exiting the vehicle
may not be possible in an emergency
due to the routing of the top tether
strap.


When installing an infant or child re-
straint system with a top tether strap
on the left second row seat, the left
third row seat should not be occupied. Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L

type anchors (at each of the rear seats) for
the installation of a LATCH child seat with
matching anchor fittings.

ing to the manufacturer’s instructions.
!An infant and child restraint system
must not be installed on the right
second row seat while a passenger
rides in a third row seat. An infant and
child restraint system installed on the
right second row seat will prevent the
use of the easy-entry / exit feature
(page 101).

An incorrectly mounted child seat may come
loose during an accident.
Damaged or impact damaged child seats or
child seat mounting fittings must be re-
placed.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system.
Children too big for child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck. A booster
seat may be necessary to achieve proper
belt positioning for children from 41 lbs until
they reach a height where a lap / shoulder
belt fits properly without a booster.
