Seat belt pre-tensioner (1)Remove the lower center pillar trim. (2)Use a flat-tipped screw driver to pull out the locking button on the harness side of the connector forward so that the connector can be unlocked for disconnection. NOTE Once disconnected from the floor wiring harness, both electrodes of the seat belt pre-tensioner connector short-circuit automatically. This prevents the seat belt pre-tensioner from accidental deployment caused by static, and etc. (3)Prepare two operation harnesses longer than 6 m to connect with the pretensioner adapter harnesses (MB991885) and insulate the connections with tape. Furthermore, connect one end of the operation harnesses with the other to short-circuit. NOTE Short-circuiting both ends of the operation harness prevents the pretensioner from accidental deployment caused by static, etc. (4)Connect the pretensioner adapter harness (MB991885) to the pretensioner 2-pin connector in order to pull the operation harness out of the vehicle. (5)Close all the doors with the windows fully closed and put a cover over the vehicle to minimize excessive noise from deployment. (6)Separate the deployment harnesses as far from the vehicle as possible and connect to the terminals of the battery removed from the vehicle. Then deploy. Caution 1)Before operating the seat belt pre-tensioner, see that no one is in or near the vehicle. 2)The operation makes the insulator of the seat belt pre-tensioner very hot. Before handling the inflator, wait more than 30 minutes for cooling. 3)If the seat belt pre-tensioner fails to operate although the procedure is respected, do not go near the seat belt pre-tensioner. Contact your local distributor. (7)Discard the operated seat belt pre-tensioner according to Disposal Procedure. DEPLOYMENT OUTSIDE THE VEHICLE Operation must be carried out in the same manner as before except for the items described below: Caution 1.Carry out air bag deployment or seat belt pre-tensioner operation on large flat area at least 6 m away from any object or person. 2.Avoid a strong wind when carrying out deployment or operation outside the vehicle. Ignite the air bag at a place upwind from the air bag module and the seat belt pre-tensioner. 1.Disconnect the negative (-) and positive (+) battery cables from the battery terminals, and then remove the battery from the vehicle. Caution Wait at least 60 seconds before proceeding with any further work after the disconnection of the battery cables. (Refer to P.52B-12.) 2.Carry out deployment of the seat belt pre-tensioner according to the following procedure.

Seat belt pre-tensioner (1)Remove the seat belt with pre-tensioner from the vehicle. (Refer to P.52B-43.) Caution Once disconnected, both electrodes of the seat belt pre-tensioner are short-circuited automatically to prevent accidental deployment caused by static etc. Still, in consideration of accidental deployment, store the air bag module on a flat area with deployment surface facing up. Also, do not place anything on top of it.

(2)Prepare two operation harnesses longer than 6 m to connect with the pretensioner adapter harnesses (MB991885) and insulate the connections with tape. Furthermore, connect one end of the operation harnesses with the other to short-circuit. NOTE Short-circuiting both ends of the operation harness prevents the pretensioner from accidental deployment caused by static, etc. (3)Route a thick wire through the holes in the seat belt retractor bracket to secure at the top of the wheel (convex part). (two locations) (4)Connect the seat belt pre-tensioner connector to the the SRS air bag adapter harness with the operation harness attached. (5)Pull out the seat belt outside the tyre. Caution Place the connector of the SRS air bag adapter harness so that it is not clamped by the tyres at deployment.

(6)Place an old tyre (without a wheel) on the tyre, to which the seat belt with pre-tensioner is secured .

(7)At a location as far away from the seatbelt pretensioner as possible, and from a shielded position, disconnect the two connected wires from each other, and connect them to the terminals of the battery (which has been removed from the vehicle) to deploy the pretensioner.
