Safety information CAUTION n 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 emergency braking, sudden swerving or an accident. n To correctly attach a child restraint system to the anchors When using the LATCH anchors, be sure that there are no foreign objects around the anchors and that the seat belt is not caught behind the child restraint. 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 emergency braking, sudden swerving or an accident. 118
