Scion xD Workshop Manuals
If you want to do fixes on your own Scion xD then it will always be a great idea to have access to a Workshop Manual to keep just for reference if you need to know tips to take off a certain part like the Gearbox and fit it again accordingly.
Scion xD Workshop Manuals will give you specified diagnostic details for the vehicle so if something is faulty it helps you identify what the situation is and some ways to correct it. You can then evaluate if this can be achieved on your own or in the event the job is too big it is possible to book your xD into a local mechanic.
