What you will need

• Steering wheel airbag (Mercedes Benz GLA250)
• Flat screwdriver or Allen wrench
• Prying tool
• 10mm wrench

Procedure

1. Open the hood. Pull the hood release under the dashboard, go to the vehicle’s front, unlock the hood latch, and pull the hood up. Use the hood strut to hold the hood up.

   

2. Disconnect the battery’s negative terminal by loosening the 10mm bolt and pulling the cable out from the battery post.
3. Go to the driver’s seat and press the horn twice to discharge any residual current. Wait 5 minutes before continuing to the next step. This procedure prevents the airbag from inflating when being removed.
4. Locate the holes on both sides behind the steering wheel. If the airbag has never been removed, you will notice to indents. Use the screwdriver to punch holes where the two indents are. 
5. Insert a screwdriver into the holes horizontally.
6. Push the screwdriver inside the hole to detach the steering wheel’s spring. Do this procedure on the other side too.
7. Once the airbag pops out, carefully pull the airbag out of the steering wheel.
8. Disconnect the electrical connectors of the airbag by pulling up the orange clip and pulling the connector out. Use a plastic prying tool to pull the clip and connector out.

   

9. Pull the clip holding the connector cables of the airbag.
10. Put the steering airbag in a safe place.
11. Get the replacement airbag and connect the electrical connectors to the proper connection port. 
12. Line up the airbag to the steering wheel and push it to lock into its place.
