Occupant safety indicator lamp while driving to make sure that the 42 indicator lamp is illuminated. If the 42 indicator lamp goes out or remains out, you may only carry a child on the front-passenger seat once the system has been repaired. A child in a rear-facing child restraint on the front-passenger seat will be seriously injured or even killed if the front-passenger front air bag inflates. RIf you have to place a child in a forwardfacing child restraint system on the frontpassenger seat, you must: - move the seat as far back as possible - use the proper child restraint recommended for the age, size and weight of the child - secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions Never place anything between the seat cushion and the child restraint system (e.g. a cushion), as this reduces the effectiveness of the BabySmart™ air bag deactivation system. The underside of the child restraint system must lie against the seat cushion of the frontpassenger seat. In the event of an accident, an incorrectly installed child restraint system could injure the child instead of offering protection. Observe the manufacturer's instructions when installing special child restraint systems. 49 G Warning When using a BabySmart™-compatible child restraint system on the front-passenger seat, the front-passenger front air bag is only disabled if the 42 indicator lamp is illuminated. Check the 42 indicator lamp repeatedly, every time you use a BabySmart™-compatible child restraint system on the front-passenger seat. Should the 42 indicator lamp not illuminate or go out while the restraint is installed, please check installation. If the 42 indicator lamp remains out, do not use the BabySmart™ child restraint system to carry a child on the front-passenger seat until the system has been repaired.
