You will find specific guidelines for engine oil, transmission gear oil, and cooling system maintenance. When referencing detailed repair data, working with accurate factory numbers directly impacts workshop productivity.

Specification Previews
The reference material provides vital engine data, such as the 1–3–2–4 ignition order and precise valve configurations. The transmission section maps out exact gear ratios for both the 5MT and 4AT systems. For routine servicing, the 2.5L engine drain plug torque is listed at 44 Nm, while the manual transmission requires exactly 3.5 liters of oil. Brake system tolerances are strictly defined: pedal free play must measure between 0.5–2.0 mm, and the front disc rotor thickness standard is 24 mm. Having these factory numbers readily accessible eliminates guesswork in the bay and ensures accuracy during every job.
