HelloCustomer this light will come on if the vehicles computer is detecting a problem. It can also come on if there is low voltage in the vehicles battery/charging system. I would start by having the battery checked. If it is fine then have the computer scanned for codes. THis can typically be done for free at most auto parts stores.
