WARNING
■When installing a child restraint system
●When installing a child restraint system on the third center 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.
● When using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
● 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. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
● 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.
● Follow all installation instructions provided by the child restraint system
manufacturer.
● When securing some types of child restraint systems in second (8-passen-
ger models) or third row 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 effectiveness. Be sure your seat belt fits snugly across
your shoulder and low on your hips. if it dose not, or if it interferes with the
child restraint, move to a different position. Failure to do so may result in
death or serious injury.
