They say your vehicle has one, but you've never seen it. And you might not even know it if you stumbled on it accidentally.
We're talking about the jack, that tool that allows you to lift one corner of the vehicle up, so someone can change a flat tire.
So you say you'd never try to change a flat anyway, so you don't care where it is. But one day, you may find yourself in a spot where you're stranded with no cell service, and you'll need to at least know the basics of what to do.
Well, here's the ironic part. Many of today's vehicles don't even have jacks and spares! Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor. If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it. Hopefully you'll be able to call roadside assistance, and they can take care of things, but circumstances may prevent help from coming for a long time. Consider watching an online video, too; there are plenty out there and may be specific to your make and model.
Some vehicles have a space-saving spare, a smaller one that is meant to get you on the road long enough to find a place to have it repaired or replaced. Those vehicles will also have a jack. Then there are vehicles that have a full-size spare tire and a jack. Again, you may prefer to call roadside assistance, but if no one is available or reachable (which is sometimes the case in a major storm), you may have to fix your own flat.
Some drivers do a "dry run" of changing a tire in their driveway during daylight hours, so they at least know where the jack and spare are and how to use them. Your service experts may be able to help you locate each part and give you some tips. And again, there are many videos online that can show you the fundamentals of jacking your make and model of vehicle.
Nobody relishes a flat tire. You may be lucky and never have to change one. But in this case, a little knowledge is better than no knowledge at all. In the unlikely case you are stranded at the side of a highway at night in the middle of the rain with no cell service, you'll at least be one step ahead.
