Disposal of Air Bag Module and Seat Belt Pre-
tensioner
NBRS0018IBefore disposing of air bag module and seat belt pre-tensioner,
or vehicles equipped with such systems, deploy the systems.
If such systems have already been deployed due to an
accident, dispose of them as indicated in ªDISPOSING OF AIR
BAG MODULE AND SEAT BELT PRE-TENSIONERº (RS-28).
IWhen deploying the air bag module and seat belt pre-
tensioner, always use the Special Service Tool; Deployment
tool KV99106400 (Kent-Moore No. J38381).

IWhen deploying the air bag module and seat belt pre-
tensioner, stand at least 5 m (16 ft) away from the deployment
component.
IWhen deploying air bag module and seat belt pre-tensioner, a
fairly loud noise is made, followed by smoke being released.
The smoke is not poisonous, however, be careful not to inhale
smoke since it irritates the throat and can cause choking.
IAlways activate one air bag module at a time.
IDue to heat, leave air bag module unattended for more than
30 minutes after deployment. Also leave seat belt pre-ten-
sioner unattended for move than 10 minutes after deployment.
IBe sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
INever apply water to the deployed air bag module and seat
belt pre-tensioner.
IWash your hands clean after finishing work.
IPlace the vehicle outdoors with an open space of at least 6 m
(20 ft) on all sides when deploying air bag module and seat belt
pre-tensioner while mounted in vehicle.
IUse a voltmeter to make sure the vehicle battery is fully
charged.
IDo not dispose of the air bag module and seat belt pre-ten-
sioner un-deployed.

CHECKING DEPLOYMENT TOOLNBRS0018S01Connecting to BatteryNBRS0018S0101CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood
blocks approximately 5 m (16 ft) away from the vehicle.
IWait 3 minutes after the vehicle battery is disconnected before
proceeding.
IConnect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the
tool, marked ªdeployment tool powerº, should glow with a
green light. If the right side lamp glows red, reverse the con-
nections to the battery.
