There are many vacuum, heater and electrical connections that are easily accessible by removing the passenger side airbag. Mercedes replaced the glove box with a passenger side airbag and a glove box beneath it, which necessitates the removal of the airbag to be able to get access to these systems again. This article will show you how to remove the passenger side airbag.

Locate the negative terminal on the battery (yellow arrow) and remove the negative ground cable (red arrow).
Figure 1

Locate the negative terminal on the battery (yellow arrow) and remove the negative ground cable (red arrow). Place the cable in a manner that it cannot come in contact with the battery while working. Allow the car to sit for at least 15 minutes before working further on it to allow any remaining electrical energy in the car to dissipate.

If the airbag has never been removed it can be easier and potentially do less damage to the trim if you help push the airbag out from behind.
Figure 2

If the airbag has never been removed it can be easier and potentially do less damage to the trim if you help push the airbag out from behind. To do this you need to remove the lower passenger side kick panel. Begin by removing any carpets on the passenger side, including the big heavy foam floor piece. Remove the single Philips head screw that holds the kick panel (red arrow) in place (yellow arrow). With the screw removed slide the kick panel towards the front of the vehicle and slip the retaining clips out from the lower dash (green arrows).

Use care when removing the panel from around the insulation under the glove box as it can tear easily.

Use care when removing the panel from around the insulation under the glove box as it can tear easily. You can now remove the kick panel from the vehicle (red arrow).

Directly under the airbag is access to the single bolt holding the airbag in place.
Figure 4

Directly under the airbag is access to the single bolt holding the airbag in place. Use a 10mm socket with an extension and remove the single bolt holding the airbag to the mount (red arrow).

The bolt is very long so do not lose it.

The bolt is very long so do not lose it.

Depending on whether the airbag has been removed before will vary the amount of force needed to push and wiggle it out form the mount (red arrow).
Figure 6

Depending on whether the airbag has been removed before will vary the amount of force needed to push and wiggle it out form the mount (red arrow). If it is really stuck it is a good idea to push it out from behind so as not to damage the trim on the exterior of the unit.

Tilt the unit forward and remove the main wiring harness from the clip on the back of the unit (red arrow) and then the two orange connections (yellow arrows).
Figure 7

Tilt the unit forward and remove the main wiring harness from the clip on the back of the unit (red arrow) and then the two orange connections (yellow arrows). Always store the airbag unit with the padded side facing upwards.

With the air bag removed you now have access to the vacuum lines, heater core lines and electrical connections.
Figure 8

With the air bag removed you now have access to the vacuum lines, heater core lines and electrical connections. Installation is the reverse of removal.

Pete2 Comments: Nick - Thank you for your prompt response! I may be mistaken, but I thought there is no scan tool available for 1993 vintage MB vehicle and to reset the codes. This 300E model code reader even has no built in red blinking light to give an error code number as opposed to the red light on 1994 E320 3.2L MB code reader.

  Followup from the Pelican Staff: I apologize, I made the mistake on the year when reading your question. Saw it as 1998. If you have a 16 pin, you need the flash code reader. Fault should clear once repair is made. If you have 38 pin, you need a scan tool. - Nick at Pelican Parts  
Pete Comments: Follow-up questions - Is the procedure to remove already deployed passenger side airbag any different? What additional steps will be required to remove it from above the glove compartment? Additionally, how to reset the SRS red light on the dash board now permanently on in my 1993 Mercedes 300E 2.8 L sedan? Will a replacement of the deployed airbag automatically take care of this light. If not what steps need to be taken to reset the light?
I did email similar question yesterday, but I am not sure if they were received.
Your help will be greatly appreciated.

Pete2 Comments: Very helpful article! A follow-up question:
1. How different is it to replace a deployed SRS airbag on 1993 MB 300E 2.8 L sedan? are there any changes in the procedure.

Thanks a lot Dmitry.

  Followup from the Pelican Staff: The procedure is similar. You will need a Mercedes-benz scan tool to clear the fault codes. - Nick at Pelican Parts  
Doug Comments: isnt there a heater hose behind the air bag needing removed before you can reach the single 10 mm bolt? Im attemptnig this now..to get to the aspirator pump for the climate control system..

  Followup from the Pelican Staff: What vehicle are you working on? is there a hose currently blocking the fastener? - Nick at Pelican Parts
