Connectivity Features:

Standard analogue gauges, basic climate controls. Limited connectivity, often requiring aftermarket Bluetooth or audio interfaces.

🔧 Maintenance

Oil Change:

Every 3,750 miles (6,000 km) or 3 months, whichever comes first (under severe driving conditions); 7,500 miles (12,000 km) or 6 months (normal conditions). Highly recommended more frequently for performance driving.

Air Filter Replacement:

Inspect every 15,000 miles (24,000 km), replace as needed or every 30,000 miles (48,000 km).

Spark Plug Replacement:

Typically every 60,000 miles (96,000 km) for iridium plugs.

Timing Belt Replacement:

Crucial: Approximately every 90,000 miles (144,000 km) or 7 years. This is a critical preventative maintenance item; failure can cause catastrophic engine damage.

Engine Oil Type:

5W-30 Synthetic (API SN/SN PLUS or ILSAC GF-5 compliant); 0W-20 for certain specific models/regions or high-performance applications. Consult manual for exact spec.

Engine Internal:

Rod bearing failures can occur if oil starvation or detonation is present. Valve stem seals can wear, leading to oil consumption. Head gasket failures on heavily modified engines.

Turbocharger:

Oil leaks or bearing failure on turbochargers, especially with age and improper maintenance. Clogged oil feed lines can starve the turbo.

Drivetrain:

AYC/ACD pump failure or leaks. Clutch wear, especially with aggressive driving. Differential wear.

Suspension And Chassis:

Worn bushings, especially on the control arms. Rust in common areas like rocker panels and strut towers, particularly in areas with road salt.

Electrical:

Corrosion on grounds and electrical connectors. Issues with immobilizer systems or ECUs.
