We recommend t ha t all infa nts and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.
To fasten a child restraint follow child restraint
instructions for routing. Then pull shoulder belt out
completely and let it retract. During the seat belt
retraction a ratcheting sound can be heard to indicate
that the special seat belt retractor is activated. The belt
is now locked. Push down on child restraint to take up
any slack.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
Note:
For child seats with mounting fittings for tether
anchorages refer to page 67 (installation of infant and
child restra int systems).Important!
The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.
Wa r n i n g !
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.

Vehicle with third row seats
3Tether anchorages for second row seats
4Tether anchorages for third row seats
This vehicle is provided with tether anchorages for a top
tether strap behind the second row seats (3) and the
third row seats (4).We recommend to install infant and child restraints on
the third row seats.
When using the third row seats observe the following:
•Installation of infant and child restraint systems
with a top tether strap is allowed 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 restraint system, since exiting the
vehicle may not be possible in an emergency due to
the routing of the top tether strap.
To store the left third row seat, see page 126.
