Front side (thorax) airbag

The front side (thorax) airbag is fixed to the lower part of the backrest of each front seat, on the door side.

On deployment, the inflatable bag tears through the module cover and the foam, and unclips the trim.

This system is operational as soon as the ignition is switched on.

REMOVAL

Before removing any component of the safety system, lock the airbag ECU using the diagnostic tool. When this function is active, all squib circuits are inhibited and the airbag warning light on the dashboard comes on (ignition on).

To work on a seat fitted with an airbag, and to ensure correct airbag deployment, strictly follow the instructions in MR365 - Bodywork.

• Disconnect the battery.
• Remove the seat.

• the airbag module wiring,
