The Kia Mentor was not a real car model produced by Kia. It appears you might be referring to a Kia model with a similar name or a typo. There is no record of a Kia car model called "Mentor" in the company's history. While Kia has a rich history of producing various models like the Picanto, Rio, Forte, and Sportage, there is no mention of a car named Mentor in their lineup. It's possible that you might be thinking of a different model or there has been a misunderstanding in the name.

It's important to double-check the information and ensure the correct model name is used when searching for service manuals or other information related to a particular vehicle. If you can provide more information, such as the year of production, body style, or any other details about the vehicle, it might be possible to identify the specific model you are interested in.
