For 2024 Yamaha moved the UMAX cars onto a new service book, LIT-19616-A3-12, and that is the reference for this car. Its model code is YUM2A24_UMAXCG.
The manual is written for the whole 2024 UMAX family, so the UMAX 1 EFI, UMAX 1 RALLY EFI, UMAX 2 EFI, UMAX 2 POWERTECH AC, UMAX 2 RALLY AC, UMAX 2 RALLY EFI, UMAX BISTRO EFI and UMAX RALLY 2+2 AC all appear in it alongside the RALLY 2+2 EFI. Because the range mixes EFI engines with AC drive systems, the relevant sections are split and labelled; read the heading before you start turning fasteners.
Content follows Yamaha's usual shop format. Periodic maintenance intervals, component removal and refitting, specifications and torque tables, wiring diagrams, and troubleshooting sequences for the engine, drivetrain, brakes, steering and electrics.
