Warning! The vehicles covered in this manual are equipped with the SRS Supplemental Safety System, better known as the airbag. Before doing any work near the cushion or steering column assembly, be sure to turn off the system to avoid injury from accidental operation (see chapter Onboard electrical equipment). The insulation and connectors of the SRS wiring harness are bright yellow. Do not connect any diagnostic devices to this circuit!
The air conditioning system is constantly under high pressure. Never disconnect refrigeration lines or remove any system components without first discharging the system. The discharge of the air conditioning system must be carried out by an experienced specialist in a car service workshop. Always wear safety goggles when disconnecting refrigerant lines!
Do not allow antifreeze to come into contact with exposed areas of the body and painted surfaces of the car. Accidental splashes should be washed off immediately with plenty of water. Remember that antifreeze is a highly toxic liquid and getting it into the body, even in small quantities, is fraught with the most serious consequences (up to death). Never leave antifreeze stored in a loosely sealed container and clean up spilled coolant on the floor without delay. Remember that the sweet smell of antifreeze can attract the attention of children and animals. Consult any car service station about ways to dispose of used coolant. In many regions of the world, special points have been set up to receive various types of detention. Never drain old coolant down the drain and onto the ground! Recently, non-toxic grades of antifreeze have been developed, but they must also be disposed of in an organized manner.
Wait until the engine has completely cooled down before proceeding with the procedure.
