🔧 Maintenance

Oil Change Interval:

Typically every 7,500 to 10,000 miles (12,000 to 16,000 km) or annually, depending on driving conditions and oil type used (refer to manual for exact recommendations).

Transmission Fluid Interval:

Automatic transmission fluid and filter change every 30,000 to 50,000 miles (48,000 to 80,000 km), depending on service classification (e.g., 'A' or 'B' service). Manual transmission fluid should be checked periodically and replaced as needed.

Engine Oil Specification:

API SG or higher, SAE 10W-40 or 15W-40 recommended for gasoline engines. Diesel engines may require specific diesel-rated oils (e.g., ACEA E2 or higher). Consult manual for specific engine variant and climate requirements.
