Driver's Front Airbag
With the MRS III system, the driver's front airbag becomes a two stage bag similar to the passenger's front side bag, introduced on the 1999 model E38/E39s. The complete assembly is mounted beneath the cover in the center of the steering wheel as with previous airbags. The assembly now contains the inert gas generator chamber and two ignition stages (ignitors).
The airbag consists of:
- Accumulator/gas generator
- Two ignition capsules
- Propellant gas - 13.5% hydrogen/86.5% oxygen
- 64 liter airbag
