 Danger !	Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from 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
 Danger !	Risk of death caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between vehicle lift columns and position the four support plates at the vehicle lift support points specified by the vehicle manufacturer.	AS00.00-Z-0010-01A

		 An engine filled with type 30 antifreeze must not be filled later on with conventional coolant as per Sheet 325.0 or 325.2. Type 30 antifreeze may not be mixed with other antifreezes and it must be replaced every 3 years! Engine damage can occur otherwise.
		 A special antifreeze (type 30) is available for the "light alloy corrosion in cooling circuit" repair case. Indications of light alloy corrosion in the cooling circuit are:  Sludging or gel formation in cooling system  Engine overheating  Flow rate deficiency in cooler In these cases, a warning label (type 30) is to be attached in a well-visible spot on the coolant expansion reservoir (2).
		 Use type 30 antifreeze if warning label (type 30) is present on the coolant expansion reservoir (2).
		 Use only approved anti-corrosion and antifreeze agents.
