This manual covers the Subaru Dex, a compact multi-purpose vehicle produced from 2006 to 2013. Based on the J4 platform, shared with the Toyota bB/Scion xB II, the Dex offers practical utility in a compact footprint. It features a 1.0L 3-cylinder engine (1KR-FE) producing approximately 68-71 horsepower and 94 Nm of torque, paired with either a Continuously Variable Transmission (CVT) or a 5-speed manual transmission. Key safety features include Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), and front airbags. While Subaru is known for its Symmetrical All-Wheel Drive and boxer engines, the Dex was a badge-engineered model, representing a departure from typical Subaru design.
