The Daihatsu Sirion, also known as the Boon in Japan, is a small hatchback that was produced by the Japanese automaker Daihatsu from 2004 to 2010. The Sirion/Boon was positioned as a budget-friendly and practical car, targeting young drivers and city dwellers. The second generation, which is covered by the 2004-2010 factory service repair manual, marked a significant departure from the first generation, featuring a more rounded and modern design. It was based on the Toyota Passo/Vitz platform, sharing many components with its sister model. This platform offered a stable and reliable driving experience, while also providing space for four passengers and modest cargo capacity. Customers had a choice of gasoline engines, including a 1.0-liter and a 1.3-liter unit, both paired with a 5-speed manual or a 4-speed automatic transmission. Although the Sirion/Boon was not a groundbreaking vehicle in terms of performance or technology, it offered a compelling combination of affordability, practicality, and fuel efficiency. Its compact size made it easy to maneuver in tight city streets, while its reliable and economical engines kept running costs low. The Sirion/Boon was particularly popular in Japan, where it was marketed as a convenient and affordable city car. It also found success in other markets, including Southeast Asia and Europe, where it was appreciated for its practicality and value. The 2004-2010 factory service repair manual is a valuable tool for mechanics and enthusiasts who want to maintain and repair their Daihatsu Sirion/Boon. It contains detailed information on every aspect of the vehicle, including engine, transmission, suspension, brakes, electrical system, and bodywork.
