Should technicians always follow OEM guidelines and manuals?

Yes. It is critical to utilize OE service information and procedures for every EV or Hybrid. While there are standard service procedures, exact procedures of different vehicle makes will vary, and technicians need to follow these by the letter. OEM Manuals provide precise model-specific information straight from the manufacturer. Opting to use OEM guidelines and manuals ensures accuracy, reliability, reducing the risk of incorrect repairs or further damage to the vehicle.
