If you need to perform adjustments for your CCM CR 40 then it is always a good idea to own a Workshop Manual for a reference if you want to know how to remove a specific component for instance the Dashboard and fit it again effectively.
CCM CR 40 Workshop Manuals can provide specific diagnostic facts for your vehicle therefore if something is not working it can help you discover what the issue is and ways to correct it. Then you are able to assess if this can be done yourself or that the job is just too big you could book your CR 40 in to a nearby repair garage.
