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.
When a junior seat (booster seat) is
installed, always ensu re that the shoulder
belt is positioned across the center of the
child’s shoulder. The be lt should be kept
away from the child’s neck, but not so that

●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
■When installing a booster seat
To prevent the belt from going into ALR

der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. (

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
