All the operations should be carried out taking great care to avoid personal injury.

The engine compartment contains many moving parts, components at high temperatures and live wires. Follow the precautions described below very carefully when carrying out operations in the engine compartment:

• switch off the engine and wait for it to cool down
• do not smoke
• no naked flames
• make sure that there is a fire extinguisher nearby.

The use of special tools is required for certain procedures. The use of these tools is vital for working in safety.Follow the current workshop safety regulations. Where necessary, the Manual contains specific procedures to be followed to prevent dangerous situations from arising.For the use of chemical products, follow the safety instructions on the card from the supplier to the consumer.The electronic ignition system produces voltages of 20,000 V and above which could be very dangerous to people especially if they are suffering from a heart condition. Therefore take great care when working on these systems or in the vicinity of their components.

WARNINGS

All the operations should be carried out taking great care to avoid damage to components.Before any operation involving electrical system components, including disconnecting the battery, make sure that the ignition key is in the OFF position.Whenever the battery terminal leads are disconnected, run the window control unit initialisation procedure (right and left sides) to store the door glass end travel, refer to    Op. 7005M40 FRONT ELECTRIC WINDOW SYSTEM ECU - R+R FOLLOWING ELECTRICAL WIRING CHECK.To release parts that are sticking, tap gently using an aluminium or lead hammer if iron materials are involved; use a wooden or resin hammer for light alloy parts.When dismantling, check that components that should be marked have the appropriate references.When refitting, lubricate the parts, where necessary, to prevent seizing during the initial operating period.When refitting it is vital to follow the tightening torques and adjustment data.Each time they are refitted, replace gaskets, oil seals, flexible washers, safetly plates, self-locking nuts, pre-treated screws and all parts that have deteriorated.Use adhesive paper or clean cloths to suitably protect those parts of the engine which, if they remain uncovered after dismantling, will allow dust or foreign bodies to enter.Only genuine spare parts should be used to replace units or components that have been removed. this is the only way of ensuring the interchangeability and perfect operation of the various components.
