Also with Front Passenger Airbag Deployment:
• Instrument Panel
• Deformed front passenger module supports (cannot be reformed)
• All sensors for front airbag on the front end [AIRBAG SENSOR,FRONT]
• Remaining transverse acceleration sensors if the mounting points are deformed in the sensor area [AIRBAG SENSOR,FRT DOOR; AIRBAG SENSOR,INTERIOR]

Also with Driver Airbag Deployment:
• Return spring with slip ring
• All sensors for front airbag on the front end [AIRBAG SENSOR,FRONT]
• Remaining transverse acceleration sensors if the mounting points are deformed in the sensor area [AIRBAG SENSOR,FRT DOOR; AIRBAG SENSOR,INTERIOR]

Also with Side Airbag Deployment:
• Pressure sensors on the deployed side [AIRBAG SENSOR,FRT DOOR]
• Transverse acceleration sensors on the deployed side [AIRBAG SENSOR,FRONT; AIRBAG SENSOR,INTERIOR]
• Cover
• Cushion
• With a folding rear seat backrest: side cushion (if equipped)
• Remaining transverse acceleration sensors if the mounting points are deformed in the sensor area [AIRBAG SENSOR,FRONT; AIRBAG SENSOR,INTERIOR]

Also:
• All automatic belt retractors with deployed belt tensioners.
• All automatic belt retractors with deployed seat belt force limiters (depending on vehicle equipment).
• Seat belt latches for all automatic belt retractors with deployed seat belt tensioners with the belt on
• Seat belt height adjuster (manual and power) for all automatic belt retractors with deployed seat belt tensioners with the belt on

The Battery Interrupt Igniter • N253• interrupts the electrical circuit each time an airbag is deployed. The Battery Interrupt Igniter • N253• must be replaced after a deployment.

PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED

Vehicle Diagnostic Tester
The Airbag Control Module Must be Replaced:
• With driver and passenger airbag deployment “but not with airbag generation 9.•, 10.• and 8.R”
• After three side airbag, driver airbag, passenger airbag or belt tensioner deployments
• if housing is damaged
• if there is deformation in the tunnel in a 200 mm circumference around the control module

Connect the Vehicle Diagnostic Tester if there is a chance the belt tensioner and/or seat belt force limiter deployed.

• Check the seat belts
• If parts of the seat belt system are removed due to an accident, replace the belt system bolts.

If needed (visual inspection), the following must also be replaced:
• All faulty components.
• After an accident, all damaged parts must be replaced. If no airbag unit damage is detected, the airbag unit can still be used.

• After replacing the airbag units or the control module, affix stickers (only tear-off strips) to the registration card and return the registration card to the relevant Sales Center or to the Importer for registration

The following components must be checked after every airbag deployment.

With Front Passenger Airbag Deployment:
• Instrument panel central tube; front passenger airbag supports and passenger airbag unit must be installed free of tension. Otherwise the central tube is to be replaced.
• Check the glove compartment for damage. Replace the glove compartment if damaged.

With Driver Airbag Deployment:
• Steering wheel
• Check steering wheel for smoke residue. If smoke residue is present, replace the steering wheel.

WARNING:
After every accident the seat belt system must be inspected systematically.
