1. Check the coolant system: Confirm if the coolant level is sufficient, and add it promptly if it is insufficient. Check for leaks in the coolant pipeline, repair or replace damaged components.
2. Check the cooling system: Clean the dust and debris on the surface of the radiator to ensure heat dissipation efficiency. Check if the fan is working properly, including speed and starting conditions, and repair or replace it if necessary.
3. Adjust driving mode or park to cool down: If the coolant temperature is found to be too high while driving, try reducing the speed and easing the motor load. Immediately find a safe place to park, let the vehicle cool down naturally, and avoid further driving that may cause more serious problems.
