            Typically every 10,000-15,000 km or 12 months, depending on engine and driving conditions. Manual will specify.
        
     
    
        
            Timing Belt:
        
        
            Critical component. Typically replaced every 60,000-80,000 km or 4-5 years for petrol engines (XU and TU series). Diesel engines may have different intervals or timing chains for some variants. Always consult the manual.
        
     
    
        
            Transmission Fluid:
