Additional Notes
- The BMW 3 Series Convertible E93 M3 trim carries a power steering specification expressed as a range rather than a fixed volume, with the service fill defined as maintaining fluid level between the minimum and maximum marks on the reservoir.
- A "between min and max" capacity specification indicates a top-off or inspection-based service rather than a measured drain-and-fill procedure, meaning no discrete fluid volume in quarts or liters is assigned to the service interval.
- The M3 Convertible's power steering system is noted as a separate system with an ATF-type cap, distinguishing the fluid reservoir access point from a conventional power steering cap and signaling that an automatic transmission fluid-compatible fluid type is applicable to the system.
- The normal use condition applies to the M3 Convertible across the 2007-2013 model years, meaning the min-to-max specification is tied to standard operating conditions rather than a severe-duty interval.
