• Evitare di viaggiare con poco carburante: Consistently running your vehicle with very low fuel levels can cause the fuel pump to overheat, as fuel acts as a coolant for the pump motor.
• Utilizzare carburante di qualità: Using clean, high-quality fuel helps prevent contaminants from entering and damaging the fuel system components.
