of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions.
GWarning!
Infants and small children should never share
a seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children too big for a toddler restraint must
ride in 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 seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap/shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
Installation of infant and child restraint 
systems
GObserve Safety notes, see page 44.GWarning!
Always lock the seat backrests in their upright
position when the rear seats are occupied by
passengers, before installing top tether
straps, or the extended cargo compartment is
not in use. Make sure that seat backrests are
secured properly by pushing and pulling on
the seat backrests. If a seat backrest is not
locked properly, the seat backrest could fold.
The child seat would no longer be supported
properly or positioned to provide its intended
benefit. That could cause serious or even fatal
injuries.
This vehicle is equipped with tether
anchorages for a top tether strap at each of
the rear seating positions. The anchorage
rings are located on the floor behind each rear
seat.
Top tether straps enable an additional
connection to be made between child
restraint systems secured with LATCH-type
anchors and rear seats. This can further
reduce the risk of injury.
XRemove the cargo compartment cover
blind, if installed (Y page 129).
XGuide the top tether strap between head
restraint and top of the seat backrest.
The head restraint must be installed and
positioned such that the top tether strap
can pass freely between the head restraint
and top of the seat backrest.
XMake sure the top tether strap is not
twisted.
XFold up anchorage ring :.XSecurely fasten hook ;, which is part of
top tether strap, to anchorage ring :.

accident. Make sure the top tether straps are
not crossed or twisted and the hook is
attached and closed properly.
Child seat anchors – LATCH-type
GObserve Safety notes, see page 44.GWarning!
Children too big for a toddler restraint must
ride in 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 seat belt positioning for children over
41 lb (18 kg) until they reach a height where
a lap/shoulder belt fits properly without a
booster.
Install child seat according to manufacturer’s
instructions.
The child seat must be firmly attached to the
right and left side anchors.
An incorrectly mounted child seat may come
loose during an accident which could result in
serious injury or death to the child.
Damaged or impact damaged child seats or
child seat mounting fittings must be replaced.
This vehicle is equipped with two LATCH-type
anchors (at each of the rear outer seats) for
the installation of a LATCH-type child seat
with matching mounting fittings.
Non-LATCH-type child seats may also be used
and can be installed using the vehicle’s seat
belt system. Install child seat according to the
manufacturer’s instructions.
LATCH-type anchors : are located between
the seat cushion and the backrest.
XInstall a LATCH-type child seat according
to the manufacturer’s instructions.
A rigid connection between the child seat
and the body of the vehicle is established.
XMake sure the seat belt for the rear center
seat can operate freely with a child seat
installed.
