If you're wondering whether or not your vehicle has StabiliTrak, the first thing to do is consult your owner's manual. Many vehicles today come with this feature as standard equipment, but it may also be an option that can be added onto certain models. You can typically find out more information about a specific model by visiting the manufacturer's website and looking up the features of that particular year and make of car. Additionally, you can take a look at any aftermarket parts websites to see if they have items specifically made for StabiliTrak systems on a particular vehicle model. If all else fails, you could always consult with a mechanic who specializes in working on your type of car who should know if your vehicle has StabiliTrak or not.
