Disposal of Air Bag Module and Seat Belt
Pre-tensioner
+Before 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-1018).
+When deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool KV99106400.
+When deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
+When 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.
+Always activate one air bag module at a time.
+Due to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave
seat belt pre-tensioner unattended for move than 10 minutes after deployment.
+Be sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
+Never apply water to the deployed air bag module and seat belt pre-tensioner.
+Wash your hands clean after finishing work.
+Place 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.
+Use a voltmeter to make sure the vehicle battery is fully charged.
+Do not dispose of the air bag module and seat belt pre-tensioner un-deployed.
CHECKING DEPLOYMENT TOOL
Connecting to battery
CAUTION:
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.
+Wait 3 minutes after the vehicle battery is disconnected
before proceeding.
+Connect 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
connections to the battery.

at a time.
DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
Deployed air bag modules and seat belt pre-tensioners 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:
+Never apply water to a deployed air bag module and seat
belt pre-tensioner.
