The fog light symbol looks a lot like the one used for the regular headlights, albeit with a squiggly line in front of it instead of three lines that look like beams.

 If you see this sign don't freak out. Instead, find a safe place to stop and inspect your tires. Carefully make your way to the nearest gas station to fill them with air. 

 Without sufficient oil pressure, the engine can't properly lubricate itself. The engine could seize and leave you stranded. As a result, it's best if you get this checked out right away.

Unless you're really handy, you should leave a fix like this to a mechanic you trust. Either way, if you see the check engine light on your dash, something's gone wrong and you shouldn't put off a trip to the shop. The sooner you can fix it, the better.

This means one of two things has happened here: Either you turned the function off because you wanted to do some sporty driving  or the feature has failed altogether. It's safest to let the computer think about traction for you, so find a way to get it back on ASAP.

There are a number of things that could have happened, but the best thing to do is stop the car and wait a good long while for the engine to cool down by itself.  If your car is so hot the engine, coolant reservoir, or coolant tank is "smoking," then you might want to call a tow service.

In the event that you see an exclamation mark with a circle around it in your dash, that means something is wrong with your brakes. There may be a problem with brake components or the hydraulic fluid may need a top-off.

 It's likely that if you stop too hard with this light on, then your car's brakes may lock up, which could make it a struggle to come to a full stop. It's best to take your car to a shop in this case, as ABS is one of the most important safety enhancements in cars since the seatbelt was invented.

 It can indicate a problem with any number of items, including the sensors that detect crashes and deploy airbags in the event of an accident have failed. If this light pops up on your dash consistently, then it's time to take your car to a shop for a lookover.
