When discarding the seat belt with pre-tensioner or a vehicle which is equipped with seat belts with pre-tensioner, be sure to deploy the seat belt pre-tensioner in advance as specified in the service procedure that follows.
|
|
|
1.Move the vehicle to flat and isolated spot.
|
|
|
2.
| caution |
Before starting the work, wait for 60 seconds or more after the disconnection of the auxiliary battery cable. (Refer to the item 5  of Service Precautions).
|
Disconnect the (-) and (+) terminals of auxiliary battery cable, and then remove the auxiliary battery from the vehicle.
|
|
|
3.Remove the lower centre pillar trim (Refer to GROUP 52A - Interior Trim ).
|
|
4.Use the flat-tipped screwdriver to pull out the locking button of harness side connector. After releasing the lock, disconnect the connector.
| note |
When the harness side connector is disconnected from the seat belt pre-tensioner, the two pins of seat belt pre-tensioner connector are automatically shorted. This prevents the unintentional deployment of seat belt pre-tensioner caused by the static or others.
|
|
|
5.Connect the deployment wires of 6 m or more to each of the two wiring harnesses of special tool adapter harness (MB991885), and cover the connection areas with insulation tape. Keep the other ends of deployment wires connected to each other (shorted).
| note |
This prevents the unintentional deployment of seat belt pre-tensioner caused by the static or others.
|
|
|
6.Connect the adapter harness (MB991885) to the 2-pin connector of seat belt pre-tensioner, and then pull out the deployment wire to outside the vehicle.
7.In order to suppress the operation sound as much as possible, fully close all the door windows and close the doors.
8.
| caution |
- Make sure that no one is present inside or near the vehicle before the deployment.
- Immediately after the seat belt pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
- If the seat belt pre-tensioner does not deploy, consult with your distributor.
|
Disconnect the deployment wire connection at a place as far as possible from the vehicle. Then, connect the wires to the removed vehicle auxiliary battery to deploy the seat belt pre-tensioner.
9.Discard the deployed seat belt pre-tensioner according to the disposal procedures (Refer to ).

|
|
|
2.
| caution |
When the connector is disconnected, the two pins of seat belt pre-tensioner are automatically shorted to prevent the unintentional deployment caused by the static or others. However, in preparation for the accidental deployment, store the pre-tensioner on a flat place with the deployment surface facing upward. Also, do not put anything on it.
|
Remove the seat belt with pre-tensioner from the vehicle (Refer to ).
|
|
3.Connect the deployment wires of 6 m or more to each of the two wiring harnesses of special tool adapter harness (MB991885), and cover the connection areas with insulation tape. Keep the other ends of deployment wires connected to each other (shorted).
| note |
This prevents the unintentional deployment of seat belt pre-tensioner caused by the static or others.
|
4.Pass a thick wire through the seat belt pre-tensioner bracket hole, and attach it to the old tyre with wheel.
5.Connect the adapter harness to the seat belt pre-tensioner connector. (Retractor side)
6.
| caution |
Set so that the connector of seat belt pre-tensioner adapter harness does not get pinched between the tyres when deployed.
|
Pull out the seat belt to outside the tyre.
|
|
7.Place an old tyre without wheel onto the pre-tensioner.
|
|
8.
| caution |
- Make sure that no one is present near the seat belt pre-tensioner before the deployment.
- Immediately after the seat belt pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
- If the seat belt pre-tensioner does not deploy, consult with your distributor.
|
Disconnect the deployment wire connection at a place as far as possible from the seat belt pre-tensioner. Then, connect the wires to the removed vehicle auxiliary battery to deploy the pre-tensioner.
9.Discard the deployed seat belt pre-tensioner according to the disposal procedures (Refer to ).
|
|
|
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 legislation. Observe the following precautions during air bag or seat belt pre-tensioner disposal:
|
|
|
1.Immediately after the seat belt pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
|
|
|
2.Do not pour water or oil onto the deployed seat belt pre-tensioner.
|
|
|
3.To the deployed pre-tensioner, substances that irritate eyes and skin may be deposited. Therefore, wear gloves and protective glasses when handling. When the substance comes in contact with eyes or skin, flush with a large amount of water.
|
