Before performing any works near assembly of a pillow or a steering column, without fail disconnect system in order to avoid getting injured as a result of its casual operation (see the Head Onboard electric equipment).

The air conditioning system constantly is under high pressure. Do not disconnect refrigerator lines at all and do not remove any components of system, previously without having executed a discharge of the last. The discharge of the air conditioning system has to be made by forces of the skilled expert in the conditions of a workshop of car service. At a rassoyedineniye of refrigerator lines surely put on goggles!


 PERFORMANCE ORDER

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!


2. Empty the cooling system (see the Head Routine maintenance).

3. Disconnect a driving cable of the valve of a heater (see an accompanying illustration).

4a. In a motive compartment disconnect hoses of a cooling path of the engine from inlet and final branch pipes of the heat exchanger of a heater on a back partition of a motive compartment (see an accompanying illustration).

4b. For collecting the spilled liquid get drain capacity under branch pipes. Give the nut of assembly of a heater located directly over inlet and final branch pipes of the heat exchanger on a back partition of a motive compartment (see an accompanying illustration).
