DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
NBRS0018S04Deployed air bag module and seat belt pre-tensioner are very hot.
Before disposing of air bag module, and seat belt pre-tensioner
wait at least 30 minutes, and 10 minutes, respectively. Seal them
in a plastic bag before disposal.
CAUTION:
INever apply water to a deployed air bag module and seat
belt pre-tensioner.
IBe sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
INo poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates throat and can cause choking.
IDo not attempt to disassemble air bag module and seat
belt pre-tensioner.
IAir bag module and seat belt pre-tensioner cannot be
reused.
IWash your hands clean after finishing work.
