DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER

SRS-67

SRS

2005 Pathfinder

Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.

The lamp on the right side of the tool, marked “deployment tool
power”, should glow green, not red.

Press the button on the deployment tool. The left side lamp on
the tool, marked “air bag connector voltage”, will illuminate and
the air bag module or seat belt pre-tensioner will deploy.

CAUTION:

Deploy only one air bag module or seat belt pre-tensioner 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 or
seat belt pre-tensioner, wait at least 30 minutes or 10 minutes, respectively. Seal them in a plastic bag before
disposal.

CAUTION:

●

Never apply water to a deployed air bag module or seat belt
pre-tensioner.

●

Be sure to wear gloves when handling a deployed air bag
module or seat belt pre-tensioner.

●

No poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates the throat and can cause choking.

●

Do not disassemble air bag module or seat belt pre-ten-
sioner.

●

Air bag modules and seat belt pre-tensioners cannot be
reused.

●

Wash your hands thoroughly after finishing work.
