	Check
 Danger!	Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by swallowing coolant.	Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses.	AS20.00-Z-0001-01A
1	Unscrew cap (2).
	Notes on coolant		AH20.00-N-2080-01A
2	Check coolant level	 Check coolant level and adjust to correct level only if coolant temperature is below 50 °C. The cooling system is filled correctly if the coolant is at the fold (arrow) of the expansion reservoir (1).
		 Before adjusting coolant to correct level, inspect anticorrosion/antifreeze protection.
3	Inspect anticorrosion/antifreeze protection	 If coolant level is low, open coolant drain plug (3) and drain coolant.
