Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
Canada only:
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
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 mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The seat 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 man-
ner.The use of infant or child restraints is
required by law in all 50 states, the District
of Columbia, the U.S. territories and all
Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured in
accordance with the manufacturer’s
instructions for the child restraint, that
complies with U.S. Federal Motor Vehicle
Safety Standards 213 and 225 and
Canadian Motor Vehicle Safety Standards
213 and 210.2.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could
injure other persons
get out of the vehicle and injure them-
selves or be injured by following traffic.
Do not carry heavy or hard objects in the
passenger compartment or trunk unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 273) and
“Useful features” (
page 282).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of:
strong braking maneuvers
sudden changes of direction
an accident
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.i

tings for tether anchorages (
