BF20.00-N-1001-01B

 Danger !	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
 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
	Notes on coolant		AH20.00-N-2080-01A
1	Inspect cooling and heating system for leaks and proper condition before replacing the coolant		AP20.00-W-2050A
2	Unscrew cap from filler neck on cooling system
3	Set temperature switch on heater operating unit, heater-air conditioning system or the automatic climate control to full heat output

		If there is severe contamination:
		
		Clean cooling system, subject to separate repair order.
5	Start engine and bleed cooling and heating system	 Allow engine to run at varying speeds for approx. 1 minute. When the engine is running the coolant level must be checked constantly, if necessary top up with coolant.
6	Turn off engine
7	Screw cap onto filler neck of cooling system
