What does " revisão" mean here exactly? Is this just some "check-up" (some control) or this is serious and means some "repair"?
"Revisão" is used in the following sentence just as some control, review:
Um contabilista fez uma revisão das contas. An accountant carried out a review of the accounts.
However, here the translation is "maintenance" so this is not just "control" but making some serious works on the car.
Addtionally, in previous lessons "maintenance" has been translated as "manutenção", "conservação".
I wonder if anyone could put more light on that.
