indicated in “SRS-45, "
DISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER"
lWhen deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool (KV99106400).
lWhen deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
lWhen 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 irri-
tates the throat and can cause choking.
lAlways activate one air bag module at a time.
lDue to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave seat
belt pre-tensioner unattended for more than 10 minutes after deployment.
lBe sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
lNever apply water to the deployed air bag module and seat belt pre-tensioner.
lWash your hands clean after finishing work.
lPlace 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.
lUse a voltmeter to make sure the vehicle battery is fully charged.
lDo not dispose of the air bag module and seat belt pre-tensioner un-deployed.

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.
lWait 3 minutes after the vehicle battery is disconnected before
proceeding.
lConnect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
