531-2. Child safety
LS500_OM_OM50F54U_(U) 1
For safety and security
■
Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seat. (Buttons displaying
the location of the anchors are
attached to the seats.)
■
Installation with LATCH system
Install the child restraint system in WARNING●
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 inju-
ries 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 th e 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 instructions pro-
vided 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 position s next to the child
restraint without inte rfering with it or
affecting seat belt effectiveness. 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 different posi-
tion. Failure to do so may result in
death or serious injury. ●
When installing a child restraint system
in the rear center se at, 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 this may cause death or serious
injuries in the event of sudden braking,
sudden swerving or an accident. ■
When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( → P.26)■
Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int 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 swerving or an accident.
