Oil Change Interval:
Typically every 15,000 km or 12 months, whichever comes first (subject to driving conditions; consult manual for specifics).
Timing Belt Replacement:
Crucial for 4-cylinder engines; interval generally around 60,000-90,000 km or 4-5 years. For 5-cylinder engines, often a timing chain or belt with longer intervals, but verification is key. Consult manual for specific engine code intervals.
Engine Oil Specification:
API SG/SH or ACEA A2/A3. Viscosity typically 5W-40, 10W-40, or 15W-40 depending on climate and manufacturer recommendation.
Coolant Specification:
G11 (blue/green) or G12 (pink/red) ethylene glycol-based antifreeze, mixed 50/50 with distilled water.
Brake Fluid Specification:
DOT 3 or DOT 4
Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, SAE 75W-90 or 80W-90
Transmission Fluid Automatic:
G009300 or equivalent ATF fluid (e.g., Dexron II/III)
Power Steering Fluid:

Common Issues:
Degradation of plastic/rubber components (hoses, seals, intake manifold gaskets), ABS sensor failures, window regulator mechanisms, ignition coil failure, suspension wear (bushings, ball joints), fuel pump issues, heater core leaks, rust around wheel arches, sills, and door bottoms.
Timing Belt Risk:
Interference engine design for most 4-cylinder variants; timing belt failure can cause catastrophic engine damage. Strict adherence to replacement intervals is critical.
Interior Wear:
Worn driver's seat bolsters, sagging headliner, and faded dashboard materials are common due to age and UV exposure.
Fuel System Issues:
Clogged fuel injectors, failing fuel pumps, and leaking fuel lines can occur.
