Fire Extinguisher Option
The M-B- fire extiguisher can be ordered in almost all markets using code 682 (68/2), and can be fitted to all M-B automobiles and 4x4s.
It is an extra cost option which is almost always installed inmediantly in front of the driver's seat for quick access.
It uses Halon, a very expensive chemical component which does not stain paint, chrome or rubber.
