AIR BAG MODULE AND SEAT BELT PRE-TENSIONER 

DISPOSAL PROCEDURES

M1524001200514

Before disposing of a vehicle which is equipped with 
air bags or seat belts with pre-tensioner, or when dis-
posing of the air bags or seat belt pre-tensioner 
themselves, the following procedures must be used 
to deploy the air bags or operate the seat belt 
pre-tensioner before disposal.

UNDEPLOYED AIR BAG MODULE AND SEAT 
BELT PRE-TENSIONER DISPOSAL

Required Special Tools:

• MB628919 or MR203491: SRS Air bag adapter harness B

• MB686560: SRS air bag adapter harness A

WARNING

•

If the vehicle is to be scrapped or otherwise dis-
posed of, deploy the air bags and operate the seat 
belt pre-tensioner inside the vehicle. If the vehicle 
will continue to be used and only the air bag mod-
ules and seat belt pre-tensioner are to be disposed 
of, deploy the air bags and operate the seat belt 
pre-tensioner outside the vehicle.

•

Since a large amount of smoke is produced when 
the air bag is deployed and the seat belt 
pre-tensioner is operated, avoid residential areas 
whenever possible.

•

Since there is loud noise when the air bags are 
deployed and when the seat belt pre-tensioner are 
operated, avoid residential areas whenever possi-
ble. If anyone is nearby, give warning of the 
impending noise.

•

Suitable ear protection should be worn by person-
nel performing these procedures or by people in 
the immediate area.
