 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
 Warning	Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.	Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
 Warning	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

	Check
1	Check fluid level.	 Only check fluid level at a coolant temperature lower than 50 °C. Before correcting the fluid level, check the anticorrosion and antifreeze protection. The fluid level must be level with the marking (arrow) on the expansion reservoir.
2	Unscrew cap of expansion reservoir.
3	Check anticorrosion and antifreeze protection.	If necessary,
		
		Correct anticorrosion and antifreeze protection.
