Parts, service, wiring, VSD, and operator manuals
Choose the publication type that matches the information you need, then verify the vehicle model and production build.
Parts manuals
Parts manuals identify assemblies and components for a particular build. They are useful when a part reference or exploded assembly view is needed. Because parts can change between orders, the agency and unit or VIN range matter as much as the public model name.
Service and maintenance manuals
Service manuals focus on repair and workshop information. Maintenance manuals emphasize inspection and preventive-maintenance work. The names sometimes overlap, so read the listing title and preview instead of choosing by label alone.
Wiring, electrical, and vehicle systems drawings
These publications contain circuit and system diagrams. “VSD” means vehicle systems drawings in this catalog. Electrical documentation is highly build-specific; match the agency, SR code, revision, and vehicle range before use.
Operator guides
Operator guides explain controls, indicators, driving procedures, and other driver-facing information. They are usually concise and should not be treated as comprehensive repair manuals.
Emergency responder and supplier documents
Emergency responder guides cover vehicle-specific incident information. Supplier manuals cover an installed component rather than the complete bus. Verify the propulsion or component model carefully.
Use the catalog hierarchy
Start with brand or model, narrow by document type, and then confirm agency and publication identifiers on the product page.
