Why the Owner’s Manual is Critical for your Car


Cars are very complex machines, with the average vehicle consisting of more than 30,000 separate components, and every car should be maintained according to the information given in the owner’s manual. Ask any qualified car mechanic in Weymouth and he will gladly confirm that the owner’s manual contains everything you need to know when servicing the vehicle.

Service History

The first section of the owner’s manual contains information on vehicle operation, while the rear section is devoted to the car’s service history. This section is where all servicing details should be recorded, and as the book is handed over to the new owner when sold, there will always be a record of the car’s service history.

Servicing Intervals

The owner’s manual would stipulate the mileage intervals for the car servicing, as well as detailing what needs to be checked and/or replaced during each service. A typical vehicle service would include the following:

  • Engine Oil Replacement – Complete with oil filter replacement.
  • Coolant Level Checking – Topped up as necessary.
  • Checking Drive Belts – Looking for wear and tear and correct tension.
  • Brake and Power Steering Fluid – Topped up when necessary.

There would be other aspects of a vehicle service that would be specified for each service, such as brake pads, gearbox oil replacement and spark plug resetting.

Wiring Diagrams

Each vehicle has its own set of electrical wiring diagrams, and these can be found in the owner’s manual, which is essential for the mechanic when dealing with electrical issues. Any fuses that have blown can easily be identified by referring to the wiring diagrams, and without this information, it might take the technician a long time to pinpoint an electrical fault.

Always refer to the owner’s manual when you need information about your car.
