The aim of this manual is to help you get the best value from your vehicle. It can do so in several ways. It can help you decide whai work must be done (even should you choose to get it done by a garagel. provide information on routine maintenance and servicing, and give a logical course of action and diagnosis when random faults occur. However, it is hoped that you will use the manual by tackling the work yourself. On simpler jobs it may even be quicker than booking the car into a garage and going there twice, to leave and collect it. Perhaps most important, a lot of money cart be saved by avoiding the costs 8 garage must charge to cover its labour and overheads.

The manual has drawings and descriptions to show the function of the various components so that their layout can be understood. Then the tasks are described and photographed in a step by-step sequence so that even a novice can do the work.

The manual is divided into thirteen Chapters, each covering a logical sub-division ot the vehicle. The Chapters are each divided into Sections, numbered with single figures, eg 5; and the Sections into paragraphs (or sub-sections), with decimal numbers following on from the Section they are in. eg 5.1. 5.2, 5.3 etc.

It is freely illustrated, especially in those parts where there is a detailed sequence of operations to be carried out. There are two forms of illustration: figures and photographs The figures are numbered in sequence with decimal numbers, according to their position in the Chapter – eg Fig. 6.4 is the fourth drawingnllustration in Chapter 6 Photographs carry the same number (either individually or in related groups) as the Section or sub-section to which they relate.

Chapter is also preceded by its own individual contents list.
