Im hoping someone here has successfully reset the wrench maintenance reminder in the dash after an oil change. I have a 2017 CX-5 GT, and I just did my first oil change at 5567 miles when the wrench appeared. I reset the maintenance interval in the infotainment screen, but the wrench continued to appear. After some research, I followed the procedure where I press and hold the dash illumination knob, and seemingly got confirmation that the wrench reminder should be reset with a flashing triangle thing, but the wrench continues to appear seemingly randomly. This morning I tried the dash illumination knob thing followed by another infotainment reset. Waiting to see if this solves the problem. I believe I have the latest infotainment firmware which I downloaded and updated myself after buying the car, from a link that was formerly active on another Mazda enthusiast site. That link has since gone inactive. Any help at all would be appreciated....including if any of you have a new source for the latest Mazda infotainment firmware. Thank you in advance.
