3. Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
4. The lamp on the right side of the tool, marked ªdeployment tool
powerº, should glow green, not red.
5. Press the button on the deployment tool. The left side lamp on
the tool, marked ªseat belt pre-tensioner connector voltageº,
will illuminate and the seat belt pre-tensioner will deploy.
CAUTION:
When deploying the seat belt pre-tensioner, stand at least 5 m
(16 ft) away from the seat belt pre-tensioner.
DEPLOYMENT OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER WHILE MOUNTED IN VEHICLE
NBRS0018S03When disposing of a vehicle, deploy air bag module and seat belt
pre-tensioners while they are mounted in vehicle.
CAUTION:
When deploying air bag module or seat belt pre-tensioner,
ensure vehicle is empty.
1. Disconnect both the vehicle battery cables and wait 3 minutes.
2. Disconnect air bag module and seat belt pre-tensioner connec-
tor.
3. Connect deployment tool [SST: KV99106400 (J38381)] to air
bag module or seat belt pre-tensioner.
For front passenger air bag module, attach deployment tool

How to Handle BatteryNBSC0003CAUTION:
IIf it becomes necessary to start the engine with a booster
battery and jumper cables, use a 12-volt booster battery.
IAfter connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
INever add distilled water through the hole used to check
specific gravity.
MEL040F
METHODS OF PREVENTING OVER-DISCHARGENBSC0003S01The following precautions must be taken to prevent over-discharg-
ing a battery.
IThe battery surface (particularly its top) should always be kept
clean and dry.
IThe terminal connections should be clean and tight.
IAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
MEL041F
IWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle
has an extended storage switch, turn it off.)
MEL042F
ICheck the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVELNBSC0003S02WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.
