7. Place three old tires without wheels on top of the tire 

secured to the air bag module, and secure all tires together 
with ropes (four locations).

WARNING

•

Before deployment, check carefully to be sure that 
no one is nearby. 

•

The inflator will be quite hot immediately following 
the deployment, so wait at least 30 minutes to 
allow it to cool before attempting to handle it. 
Although not poisonous, do not inhale gas from 
air bag deployment. See Deployed Air Bag Module 
and Operated Seat Belt Pre-tensioner Disposal 
(Refer to 

P.52B-403

) for post-deployment handling 

instructions. 

•

If the air bag fails to deploy, do not go near the 
module.

8. At a location as far away from the air bag module as 

possible, and from a shielded position, disconnect the two 
connected wires from each other, and connect them to the 
two terminals of the battery (which has been removed from 
the vehicle) to deploy the air bag. 

9. Discard the deployed air bag module as specified in 

Deployed Air Bag Module and Operated Seat Belt 
Pre-tensioner Disposal (Refer to 

P.52B-403

). 

.

DEPLOYMENT OUTSIDE THE VEHICLE <Seat belt 
pre-tensioner>

DANGER

Wait at least 60 seconds after disconnecting the bat-
tery cables before doing any further work (Refer to 

P.52B-26

).

WARNING

•

Battery posts, terminals and related accessories 
contain lead and lead compounds. WASH HANDS 
AFTER HANDLING.

•

Operate the seat belt pre-tensioner in a wide, flat 
area at least 6 meters (20 feet) away from obsta-
cles and other people.

•

Do not perform operation outside if a strong wind 
is blowing. If there is a slight breeze, place the seat 
belt pre-tensioner downwind from the battery.

1. Disconnect the negative (

−) and positive (+) battery cables 

from the battery terminals, and then remove the battery from 
the vehicle.

WARNING

Store the seat belt pre-tensioner on a flat surface with 
its operation surface facing up. Do not place anything 
on top of them.

2. Remove the seat belt pre-tensioner from the vehicle (Refer 

to 

P.52B-380

).

3. Use a flat-tip screwdriver to unlock the harness side 

connector locking button by withdrawing it toward you in two 
stages.

4. Disconnect the D-22 or D-33 harness side connector.

5. Connect two wires, each 6 meters (20 feet) or longer, to the 

two leads of special tool pre-tensioner adapter harness 
(MB991885), and cover the connections with insulation 
tape. The other ends of the two wires should be connected 
to each other (short-circuited), to prevent sudden 
unexpected operation of the seat belt pre-tensioner.

6. Connect the special tool pre-tensioner adapter harness 

(MB991885), which the deployment wires is attached to, to 
the seat belt pre-tensioner connector.

CAUTION

The adapter harness below the wheel should be loose. If it 
is too tight, the reaction when the seat belt pre-tensioner 
operates could damage the adapter harness.
7. Pass the thick wires through the hole on the seat belt 

pre-tensioner bracket and secure them to the front (raised 
part) of the wheel in two places.

8. Pull the seat belt out to the outside of the tire, and then place 

one tire without a wheel on top.

WARNING

•

Before operation, check carefully to be sure that 
no one is nearby.

•

The inflator will be quite hot immediately following 
the operation, so wait at least 30 minutes to allow 
it to cool before attempting to handle it. Although 
not poisonous, do not inhale gas from seat belt 
pre-tensioner operation. See Deployed Air Bag

posal (Refer to 

P.52B-403

) for post-operation han-

dling instructions.

•

If the seat belt pre-tensioner fails to operate, do 
not go near the seat belt pre-tensioner.

9. At a location as far away from the air bag module as 

possible, and from a shielded position, disconnect the two 
connected wires from each other, and connect them to the 
two terminals of the battery (which has been removed from 
the vehicle) to operate the seat belt pre-tensioner.

10.Discard the operated seat belt pre-tensioner as specified in 

Deployed Air Bag Module and Seat Belt pre-tensioner 
Disposal (Refer to 

P.52B-403

DEPLOYED AIR BAG MODULE AND OPERATED 
SEAT BELT PRE-TENSIONER DISPOSAL

After deployment and operation, the air bag module and seat 
belt pre-tensioner should be disposed of in the same manner 
as any other scrap parts, adhering to local laws and/or legisla-
tion. Observe the following precautions during air bag or seat 
belt pre-tensioner disposal:
1. The inflator will be quite hot immediately following 

deployment, so wait at least 30 minutes to allow it cool 
before attempting to handle it.

2. Do not put water or oil on the air bag after deployment or on 

the seat belt pre-tensioner after operation.

WARNING

If after following these precautions, any material does 
get into the eyes or on the skin, immediately rinse the 
affected area with a large amount of clean water. If 
any irritation develops, seek medical attention.

3. There may be material on the deployed air bag module or 

the operated seat belt pre-tensioner, that could irritate the 
eye and/or skin. Wear gloves and safety glasses when 
handling a deployed air bag module or the operated seat 
belt pre-tensioner.
