Essential equipment
diagnostic tool

The driver's front airbag is fitted with a two-stage inflator bag (low and high output).

It inflates depending on the severity of the impact or the position of the driver's seat adjustment.

To deploy, the airbag bag tears through the steering wheel cover.

REMOVAL

  • Disconnect the battery.
IMPORTANT
  • Before removing any component of the safety system, the airbag control unit MUST be locked using the diagnostic tool.

    When this function is active, all firing circuits are inhibited and the airbag warning light on the dashboard comes on (ignition on).

  • Never handle pyrotechnic systems (pretensioner or airbag) near a heat source or flame, as there is a risk of accidental deployment.
WARNING

The airbag control unit MUST be locked before starting removal. Locking the airbag control unit also unlocks the electric steering column lock.
