This indicator light stays on for a few seconds when the ignition is switched ON.
It also illuminates when the DSC OFF switch is pressed and TCS/DSC is switched off.
Refer to DSC OFF Switch (Search).
If the light remains illuminated and the TCS/DSC is not switched off, take your vehicle to an expert repairer, we recommend an Authorised Mazda Repairer. The DSC may have a malfunction.
