Owner's Manuals, usually found in the glove compartment of your automobile, were published by the auto factory to acquaint owners with the proper operation and maintenance of their new car or truck. Generally, they familiarize the owner with the features engineered into the automobile to assure economical and efficient operation. They include instructions for operating all standard equipment and most optional or special equipment available at that time.

Instrument controls, lighting, radios, brakes, tires and wheels, towing and seat adjustment are among the topics sometimes covered. In addition, many auto owners manuals include some basic maintenance information (brake fluid, cooling system, oil requirements, etc) and specifications (engine, fuses, light bulbs, fluid capacities, etc.)

Truck owners manuals, like car owners manuals, contain operating instructions, maintenance recommendations and service specifications. Instrument panel and controls, 4 wheel drive operating instructions, brakes operating instructions, fuses and circuit breakers are among the topics sometimes included.
