What must a customer do before any repairs can be made?

Before any repairs can take place, it is essential for the customer to provide full customer approval. This ensures that the customer is aware of the work that is going to be done on their vehicle and agrees to it. Obtaining approval not only serves to protect the customer's interests by ensuring they are informed about the repairs but also establishes a clear agreement between the service provider and the customer regarding the scope and cost of the work. This step is crucial in maintaining trust and transparency in the service process.

Other options, while they may be relevant in specific contexts, do not fulfill the fundamental requirement of obtaining customer approval for repairs. Being informed of potential risks is important, but it does not equate to giving consent. Similarly, signing a waiver or making a partial payment does not replace the need for the customer's explicit agreement to proceed with the repairs.
