■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may spring
up due to the rebound of the seat
cushion. Release the buckle while
holding down the child restraint
system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●Ensure that the belt and plate
are securely locked and the
seat belt is not twisted.
●Shake the child restraint system
left and right, and forward and
backward to ensure that it has
been securely installed.
●After securing a child restraint
system, never adjust the seat.
●When a booster seat is
installed, always ensure that the
shoulder belt is positioned
across the center of the child’s
shoulder. The belt should be
kept away from the child’s neck,
but not so that it could fall off the
child’s shoulder.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting s eat belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, move to a differ-
ent position. Fa ilure to do so
may result in death or serious
injury.
●When installing a child restraint
system in the ce nter rear seat,
adjust both seatbacks at the
same angle. Otherwise, the
child restraint system cannot be
securely restrained and this
may cause death or serious
injuries in the event of sudden
braking, sudden swerving or an
accident.
