2003 Suzuki Aerio Service and Repair Manual

For its second season, the Aerio added an all-wheel-drive option, available with the automatic on the GS sedan and SX wagon, while the front-drive S, GS and SX carried on. Power still came from the 145-horsepower 2.0-liter DOHC four-cylinder, making 2003 the last year before the switch to a 2.3-liter engine. This service and repair manual covers the 2003 lineup specifically, including the extra driveline hardware on AWD cars, with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules keyed to this model year.

Engines covered

Known issues on the 2003 Aerio. Two recalls are on federal record: a windshield-mounting recall (FMVSS 212) because poor paint adhesion could leave the windshield insufficiently bonded to the body; a recall for five-speed manual cars whose shift-cable retaining clip could break when first gear was forced, disconnecting the shifter. NHTSA also logs 36 owner complaints, most often about the powertrain and wheels. The manual's inspection procedures and specifications help confirm the affected parts are correct and secure.
