Recommendations:
- The manufacturer recommends using ethylene glycol-based coolant (antifreeze). Check with your dealer - seller of the car for the brand of liquid poured into your car.
- Do not mix liquids of different colors, different manufacturers. If you need to add coolant, but you do not know the brand of liquid poured into the system, replace all the liquid in the cooling system.
- Use only products from proven manufacturers. Remember that using low-quality coolant leads to expensive engine repairs! Before starting work, place the car on a level surface.
Warnings:
- Check the coolant level only when the engine is cold.
- Coolant is toxic, so take precautions when handling it.
- Do not pour fluid into the tank above the "MAX" mark, as its volume will increase when the engine is running.
- When starting the engine, the expansion tank cap must be closed.
- Monitor the coolant level. A sharp decrease or increase should be a signal for an immediate check of the engine cooling system.
- If the freshly poured antifreeze suddenly turns brown quickly, it means you were sold a fake, to which they "forgot" to add corrosion inhibitors. Replace the liquid as quickly as possible before it has time to corrode the cooling system.

The expansion tank is installed in the engine compartment on the left side.

1. The coolant level must be between the "MAX" and "MIN" marks on the wall of the expansion tank.

2. To add coolant, unscrew the expansion tank cap...

3. ...and add liquid to the required level.

4. Screw on the expansion tank cap.
Warning: Make sure the expansion tank cap is tightly screwed in. The expansion tank is under pressure when the engine is running, so coolant may leak from under a loosely screwed cap.
