Your Fiat Punto Manual
The aim ol this manual is to help you get the best value from your vehicle, It can do so-ln several ways. It can help you decide what worfc must be done (even should you choose to get It dons by a garage), 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 tho car into a garage and going there twice, io leave and collect it. Perhaps mosl important, a lot of money can be saved by avoiding the costs a 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 layoul can be understood, Then the tasks are described and photographed in a clear step-by-step sequence. References to the 'left' or 'right' are In the sense of a person in the driver's seat facing forward.

do Weekly checks
Introduction
There are some very simple checks which need only take a few minutes to carry out, but which could save you a lot of inconvenience and expense.
These Weekly checks require no great skill or special lools, and the small amount of lime they take to perform could prove to be very well spent, for example;
P Keeping an eye on tyre condition and pressures, will not only help to stop them wearing out prematurely, but could also save your life.
C Many breakdowns are caused by electacai problems. Battery-relalod faults are particularly common, and a quick check on a regular basis will ofton prevent the majority of these.
• If your car develops a brake fluid teak, the first time you might know about it is when your brakes don't work properly. Checking the level regularly will give advance warning of this kind of problem.
• If the oil or coolant levels run low. the cost of repairing any engine damage will be far greater than fixing the leak, for example.
