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.
●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 seat 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.

WARNING
●When installing a child restraint
system in the rear center seat,
adjust both seat cushions to the
same position and align both
seatbacks at the same angle.
Otherwise, the child restraint
system cannot be securely
restrained and t his may cause
death or serious injuries in the
event of sudden braking, sud-
den swerving or an accident.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.
■When installing a booster
seat
To prevent the belt from going into
ALR lock mode, do not fully
extend the shoulder belt. ALR
mode causes the belt to tighten
only. This could cause injury or
discomfort to the child. ( P.31,
33)
■Do not use a seat belt
extender
If a seat belt extender is used
when installing a child restraint
system, the seat belt will not
securely hold the child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.
