Removing
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 (recognized by a signal in the instrument cluster), the engine 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).
- Disconnect the battery Ground (GND) cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
- Remove the front wheel housing liner. Refer to → Body Exterior; Rep. Gr.66; Wheel Housing Liner; Front Wheel Housing Liner, Removing and Installing.
- Remove the front wheel spoiler. Refer to → Body Exterior; Rep. Gr.66; Wheel Housing Liner; Front Wheel Housing Liner, Removing and Installing.
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.
- Remove the bolt -2- and the front airbag crash sensor -3-.
- Pull out connector lock -4--arrow- and press down, disconnect harness connector -1- at the crash sensor.
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 the charger, such as the Battery Charger -VAS5095A- to the jump start of the 12V vehicle electrical system.
- Turn on the ignition.
- Connect the battery GND 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 Diagnostic Trouble Code (DTC) memory, erase it and check it again. Refer to Vehicle Diagnostic Tester.
Installation notes, for example tightening specifications, replacing components. Refer to → Chapter "Component Location Overview - Airbag Crash Sensors".
