WARNING
Follow all Safety Precautions when working with pyrotechnic components. Refer to → Chapter "Pyrotechnic Components Safety Precautions".
There is a risk of injury if the engine starts automatically in vehicles with the Start/Stop System.
- For vehicles with an activated Start/Stop System (recognizable from a notification in the instrument cluster), the motor can be started automatically if needed.
- Make sure that the start/stop system is deactivated when working on the vehicle (turn off the ignition, turn on the ignition when necessary).
- Turn on the ignition.
- Disconnect the battery ground cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
- Remove the front noise insulation. Refer to → Body Exterior; Rep. Gr.66; Underbody Panel; Overview - Underbody Panels.
WARNING
Before handling pyrotechnic components (for example, disconnecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
- Pull the locking mechanism -4- down -arrow- and disconnect the connector -1-.
- Remove the bolt -3- and the front airbag crash sensor -2-.
Installing
WARNING
- Follow all Safety Precautions when working with pyrotechnic components. Refer to → Chapter "Pyrotechnic Components Safety Precautions".
- Before handling pyrotechnic components (for example, connecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
Install in reverse order of removal. Note the following:
Note
- Make sure the connectors are installed correctly and are secure.
- Make sure the wires do not get caught.
WARNING
Ignition must be on when connecting battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. There must not be anyone inside the vehicle when connecting the battery.
DANGER!
When working on vehicles with the ignition already switched on or that are ready to drive there is a danger of the engine starting unexpectedly and of being poisoned by gas in enclosed areas. Risk of body parts and/or clothing being clamped or pulled.
Perform the following before switching on the ignition:
- Move the selector lever into P.
- Activate the parking brake
- Turn off the ignition.
- Open the hood
- Connect Battery Charger -VAS5095A- to the battery jump start terminal.
- Turn on the ignition.
- Connect the battery ground cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
Note
If the Airbag Indicator Lamp -K75- indicates a fault, check the DTC memory, erase it and check it again → Vehicle diagnostic tester.
