	Checking
	Risk of accident  caused by vehicle starting off by itself when engine is running. Risk of injury  caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	-
	Risk of explosion  caused by welding or soldering work on closed air conditioning system. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with liquid refrigerant.	Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been discharged.	-
	Procedure if air conditioning system is damaged or leaking		AH83.30-N-0004-01A
	Notes on handling refrigerant R134a	Air conditioning with refrigerant R134a	AH83.30-N-0003-01A
1	Evacuate air conditioning system	For air conditioning service stations see GOTIS http://gotis.aftersales.daimlerchrysler.com
2	Fill air conditioning system with nitrogen	First fill system to 15.5 bar of system pressure, reduce system pressure to 15 bar after approx. 10 minutes. This system pressure must be maintained for at least 4 hours. Temperature changes during the pressure test can cause pressure surges, e.g. due to weather changes, transition from day to night, cooling down of engine compartment. Consistent ambient conditions must be strictly ensured.
3	Check air conditioning circuit for leakage.	Check for leaks using a leak detection spray in case of pressure drop. If there is a pressure loss and no leak is found in the refrigeration circuit: ↓	AR83.30-P-5520V
	Air conditioning nonfunctional or too low cooling output or noise during air conditioning operation	Perform leak test using contrast agent.	-
4	Fill air conditioning system	Fill air conditioning system with refrigerant R 134a
