What does dsc off mean mazda 3?

If You get a message on Your Mazda3 showing "DSC OFF", first You should know that DSC stands for Dynamic Stability Control. This is a fancy term for what amounts to Your Mazda limiting the amount of spin from Your wheels. Let me clarify what that means: Say You're in some mud, or snow, depending on where You live. Typically, if You floor the gas, Your wheels will spin there. With DSC on, Your engine won't have increased power (no spin), so it'd difficult to free Your vehicle. You can typically turn the DSC off with a small button; You might want to if You're trying to clear snow, or if You're doing drag racing: legally, I hope!
