Daewoo Motors grew out of National Motors, a South Korean company founded in 1937 that was absorbed by the Daewoo industrial group in the early 1980s and renamed Daewoo Motor. The wider Daewoo group, established in 1967, expanded into electronics, shipbuilding and heavy machinery before the car business was sold to General Motors in 2002 and later became GM Korea.

Daewoo is best remembered for practical, affordable cars sold in Korea and exported around the world, including the Lanos, Nubira, Leganza and Matiz model ranges, many developed with European engineering partners. The group also produced construction equipment and large diesel engines for industrial and marine use through its heavy-industry companies.

Workshop manuals for Daewoo cover engine repair and overhaul, fuel and ignition systems, manual and automatic transmissions, suspension and brakes, electrical wiring diagrams, torque specifications, diagnostic procedures and the manufacturer's scheduled maintenance program for each model and engine type. Wiring diagrams and connector views are included for the electronic engine management used on later Daewoo models.

Owners of Daewoo cars, independent garages and technicians working on Daewoo-badged vehicles or Korean-built machinery will find factory service manuals valuable for accurate repairs, correct specifications and dependable operation. Because many Daewoo cars are now affordable older vehicles, owners and small workshops value the original procedures for keeping them economical and dependable. Correct data also helps with parts identification on models sold under different export names.
