The Concierge 4/6 arrived as a gas passenger car, and for the 2000 G20-AU the factory reference is LIT-19616-G2-0A. Its model code is G20AU.
Yamaha wrote this manual to serve model years 2000, 2001 and 2002, so the later G20-AW and G20-AX cars share the same pages. For a resort or community fleet that bought Concierges across several seasons, that means one book rather than three.
Coverage runs the way a technician works through a car: periodic maintenance intervals, engine and carburetor service, the drive and transmission, brakes and parking brake, steering and front suspension, the frame and body panels, then the electrical system with its wiring diagram. Specifications and torque values sit with the procedures they belong to.
If you are chasing a fuel delivery complaint or setting brake free play on a six-passenger car that spends its days loaded, the factory figures here are the ones to work to.
