Your car has two very different manuals. One tells you how to use and look after it. The other tells a mechanic how to take it apart and put it back together. Knowing which is which saves time, and sometimes money.
What the owner’s manual covers
The owner’s manual comes with the car and is written for drivers. Most manufacturers also publish it free online. It covers:
- controls, displays and what each dashboard warning light means
- where the fuse boxes are and what each fuse protects
- fluid types and capacities, including the right engine oil
- tire sizes and cold tire pressures
- the maintenance schedule and service intervals
- towing limits and safety information
What the workshop manual covers
The workshop manual, also called a service or repair manual, is written for technicians. It picks up where the owner’s manual stops:
- step-by-step removal and installation procedures
- torque specifications for bolts and fasteners
- wiring diagrams and connector pinouts
- diagnostic procedures for fault codes
- component locations, specifications and tolerances
- special tools needed for each job

Which one do you need?
Start with the owner’s manual if you want to know what a warning light means, which fuse to check, what oil to buy or when a service is due. It is free, and we link to the official copy on our owner’s manuals page.
Get the workshop manual if you are replacing a part, chasing an electrical fault, following up a fault code or need a torque figure. Those details are not in the owner’s manual.
For safety-critical work on brakes, steering, airbags or fuel systems, follow the full workshop manual procedure for your exact vehicle, or have the work done by a qualified technician.
