For safety and security WARNING ■
When installing a child restraint system ●
When a booster seat is installed, always en sure 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 ch ild’s shoulder. Failing to do so may result in
death or serious injury in the event of su dden braking, sudden swerving or an acci-
dent. ●
Ensure that the belt and plate are securely locked and the seat belt is not twisted.●
Shake the child restraint syst em left and right, and forward and backward to ensure
that it has been securely installed. ●
After securing a child restraint system, ne ver adjust the seat.●
Follow all installation instructions provided by the child restraint system manufacturer.●
When securing some types of child restraint systems in se cond or third row seats, it
may not be possible to properly use the se at belts in position s next to the child
restraint without interfering with it or affe cting seat belt effect iveness. 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 position. Failure to do so may
result in death or serious injury. ■
Do not use a seat belt extender
If a seat belt extender is used when insta lling 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 swerving or an
accident. ■
To correctly attach a child re straint system to the anchors
When using the LATCH anchors, be sure that there are no foreig n objects around the
anchors and that the seat belt is not caught behind the child restraint system. Make sure
the child restraint system is securely attached , or it may cause death or serious injury to
the child or other passengers in the event of a sudden stop, sudden swerve or accident.
