Installing the front passenger airbag
Danger! Immobilization period-threatening injuries!
- Before performing any work on the airbag, always disconnect the battery ground lead from the battery.
- Airbag unit may only be set down with the cushion (airbag itself) facing upwards.
- For ADDITIONAL INFORMATION see: 72 00... Safety regulations on handling airbag system components/gas generators
Danger! Immobilization period-threatening injuries!
- All work on pyrotechnic parts may be carried out by technically experienced and appropriately trained personnel only.
- Replace any damaged part or ones that have been dropped.
- For ADDITIONAL INFORMATION see: 72 00 Safety regulations on handling components with gas generators.
The screw connection of the front passenger airbag to the instrument panel depends on whether the removed parts or new parts are installed. Note the following case distinction.
- Variant A (installation of the removed front passenger airbag on a new instrument panel)
Position passenger airbag (2).
Fasten the front passenger airbag (2) with screws 12.
Tighten the screws (1).
A retorque of the screws using the torque wrench is not permitted!
TIGHTENING TORQUES SPECIFICATIONFront passenger airbag to dashboard Oval-head screw for thermoplastic Tightening torque 2.3 Nm - The tightening torque must be applied on at least 11 screws.
- If the tightening torque is not reached for more than one screw, the instrument panel must be replaced.
- Variant B (installation of a new front passenger airbag on the removed instrument panel)
The removed front passenger airbag was fastened with 6 screws.
- Position passenger airbag (2).
- Fasten the front passenger airbag (2) with screws 12.
- Tighten the screws (1).
A retorque of the screws using the torque wrench is not permitted!
TIGHTENING TORQUES SPECIFICATIONFront passenger airbag to dashboard Oval-head screw for thermoplastic Tightening torque 2.3 Nm - The tightening torque must be applied on at least 11 screws.
- If the tightening torque is not reached for more than one screw, the instrument panel must be replaced.
- Variant C (installation of a new front passenger airbag on the removed instrument panel)
The removed front passenger airbag was fastened with 11 screws.
Position passenger airbag (2).
NOTE: TECHNICAL INFORMATION
The marked screw point 3 serves as an example for the unused screw point. - Do not
use the marked screw point (3) when removing the front passenger airbag.
Fasten the front passenger airbag (2) with 11 screws at the same screw points already used.
- Tighten down screws (1).
A retorque of the screws using the torque wrench is not permitted!
TIGHTENING TORQUES SPECIFICATIONFront passenger airbag to dashboard Oval-head screw for thermoplastic Tightening torque 2.3 Nm - Make sure that the tightening torque is reached in all 11 screws.
- If the tightening torque is not reached for a screw, the instrument panel must be replaced.
Check
NOTE: TECHNICAL INFORMATION
Although the screws were correctly tightened using the torque wrench, it is possible that the screw head is not seated without a gap. The following procedure is applicable to all present cases. - Check if all the screw heads (1) rest without any gaps as shown (using a thin paper strip (2)).
Result
» The paper strip (2) slides under the screw head (1). The screw (1) does not rest without any gaps. The threaded connection is not correct.
Measure
- Release screw (1) and tighten it once again to the same, prescribed tightening torque without retorque.
Increasing the tightening torque in order to seat the screw head in the correct position is not permitted!
Repeating the threaded connection is only permitted once per screw point.
Result
» The paper strip (2) does not slide under the screw head (1). The screw (1) rests without any gaps. The threaded connection is correct.
Measure
- No action required.
Result
» The paper strip (2) passes under the screw head (1) despite one repeated threaded connection. The screw (1) does not rest without a gap despite one repeated threaded connection. The threaded connection is not correct.
Measure
- Replace the instrument panel.
- Release screw (1) and tighten it once again to the same, prescribed tightening torque without retorque.
