  Spark plugs should be inspected around 20,000 kilometers. They need to be cleaned or replaced if worn. Good spark plugs ensure efficient fuel combustion in the engine.

• Scheduled Timing Belt Replacement

  The timing belt should be replaced between 80,000 to 100,000 kilometers. This is important to keep the engine's internal components synchronized properly.

• Fuel System Cleaning

  Every 30,000 kilometers, a fuel system cleaner should be used. This cleans the injectors and other parts of the fuel system to maintain optimal fuel delivery.

• Regular Valve Clearance Check

  Valve clearances should be checked around 40,000 kilometers. Adjustments are made if needed. Proper valve clearance ensures good engine performance.

• Regular Brake Fluid Replacement

  Every 40,000 kilometers, the brake fluid should be drained and replaced. This maintains proper braking efficiency and prevents moisture buildup in the system.

• Regular Check of Belts and Hoses

  Around 20,000 kilometers, all belts and hoses should be visually inspected. Any that are cracked or worn need to be replaced. Healthy belts and hoses prevent breakdowns.

• Regular Chassis Lubrication

  Every 20,000 kilometers, joints on the suspension and other chassis parts should be lubricated. This keeps the vehicle handling well.
