E34 Generation:
Second generation of the BMW 5 Series, introduced in 1988 for the 1989 model year. The 540i was a late addition to the E34 lineup, representing the pinnacle of performance for the non-M models.
540I Introduction:
The 540i model was introduced for the 1994 model year in North America, effectively a facelift/update to the E34 platform, but this manual specifies 1991. This indicates the manual might cover early development or international markets where the 4.0L V8 was available earlier in the E34's lifecycle, or it's a slight mislabeling and pertains to later E34 V8 models. Assuming the product name is correct for a 1991 model, it would refer to the pre-facelift E34 with the M60 engine, which became more widely available in later years. (Editor's Note: Typically, the 540i designation with the M60B40 engine was introduced for the 1994 model year in the US. If this manual is truly for a 1991 model, it might pertain to the European market where V8s were introduced earlier, or it could be a very early production or special order vehicle. The manual's comprehensive nature would be crucial to confirm exact model applicability if discrepancies arise).
