My oil light (rench) came on today 3/29/2019? I just had it service for the first time 2/12/2019
If your dealer didn't reset the oil change light it will come on at your scheduled milage
CAN I RESET IT ? AND HOW
The wrench indicator light means that your Mazda is due for some service. This light’s illumination can mean that your Mazda is in need of tire rotation, an oil change, or other types of service work. If you just had it serviced a few weeks ago, they might have forgotten to reset it. You could follow the procedure in your owners manual to reset the light, Or go to the dealership when you're near and have them do it; it will only take a few minutes. They should be apprised of this lack of assistance. We have CX-5 and service people are sometimes rushed and forget to do this.
