Dismantling
1. Follow all safety rules when working with passive safety systems.
GENERAL INFORMATION, Safety precautions when working with the airbag system (SRS).

1. Install the control units and connect the connector blocks.
2. Install the control units onto the airbag module and tighten the Torx screws to 2.5 Nm.
3. Install the airbag module and connect the connector.
NOTE: If a component of the passive restraint system needs to be replaced, the bar code of the new component must be recorded.
4. On models with heated steering wheel: Connect the heated steering wheel control module connector.
5. Position the airbag module on the steering wheel and gently press until the spring clips engage.
