    METHOD OF USING THE REPAIR MANUAL This manual includes all main service operations. Primarily it is intended for left-hand drive cars, but the application to right-hand cars should present no difficulties as any differences are obvious. CLASSIFICATION We have shown at the beginning of this manual a classification of the main units of the car. The three figured number in front of each unit corresponds to the operation number relating to this particular unit.
