Checking the coolant level
If possible, open the compensating tank cap (1) only when the engine is cold. When
opening the system while the engine is hot, air may penetrate into the system and
impair the function. A float (2) indicating the fluid level is provided behind the cap.
When the engine is cold, the fluid level should be between min and max. Place the
vehicle on a flat surface to ensure proper measurement.
