Discovery Generations:

The Discovery 2 (LD) was produced from 1998 to 2004. The 2006 model listed in the manual likely refers to a specific export market or a closely related successor variant if the Discovery 2 production extended past 2004 in certain regions, or it might be a typo and refer to the later Discovery 3 (LR3).

Discovery 2 Facelift:

The Discovery 2 received a significant update in 2002, introducing the larger 4.6L V8 engine, improved interior, and updated electronics.

Production Period:

Discovery 2: 1998-2004. If the manual truly covers a 2006 model for the Discovery 2, it implies continued production in specific markets or a reference to later models that might share some components.
