Seat Belt Pre-TENSIONER Deployment Inside The Vehicle

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Move the vehicle to flat and isolated spot.
CAUTION: Before starting the work, wait for 60 seconds or more after the disconnection of the battery cable. (Refer to the item 5 of SERVICE PRECAUTIONS ).
Disconnect the (-) and (+) terminals of battery cable, and then remove the battery from the vehicle.
Remove the center pillar trim lower (Refer to INTERIOR TRIM ).
Use the flat-tipped screwdriver to pull out the locking button of floor harness connector. After releasing the lock, disconnect the connector.
NOTE: When the floor harness connector is disconnected from the seat belt pre-tensioner, the two pins of the seat belt pre-tensioner connector are automatically shorted. This prevents the unintentional deployment of the seat belt pre-tensioner caused by the static or others.

Connect the deployment wires of 6 m (20 feet) 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.

CAUTION:
- Make sure that no one is present inside or near the vehicle before the deployment.
- Immediately after the 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 battery to deploy the seat belt pre-tensioner.
Discard the deployed seat belt pre-tensioner according to the disposal procedures (Refer to SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES ).
