The 10 Most Confusing Car Buttons And Symbols — And What They Mean

It cycles through “program type” and “category” to shuffle through your playlists, not that its name is even remotely helpful, as ejp hates automatic transmissions points out.

The PTY/CAT button, native to many fine Subarus. Experts have been debating what this button actually does since it found its way into Japanese cars over a decade ago. Some say that when this button is pressed, somewhere in the world, a random putty cat is killed. Others say that it puts your car in “PARTY CAT” mode, but nobody really knows what that means, either.

“BC” cycles through your dashboard display. Not that a BMW driver ever uses his turn signals, of course.

This light is obvious to gearheads, but more than a few normal folks don’t realize it means the air in one of your tires is low. Drivers’ ignorance of what this light means leads to a lot of headaches for mechanics like Hello I’m Justin:

When I was a service advisor, for most of my customers it was this. This light would single handedly fill my morning with quick tire fills. We had to keep an air tank on the service drive just for this light. Hate it.

You see this on a lot of older cars. With.a.G explains why it makes sense, kind of.

When driving at night, it’s important not to burden a driver with the need to remove a hand from the wheel, especially when visibility conditions are changing. So, we’ll put high beam switch next to the BRAKE PEDAL.

You sometimes see this on older VWs and Audis. No, it doesn’t blast George Clinton at the highest possible volume. Funk means “radio” in German, and the button is a radio kill switch for police cars and taxi cabs.

If any automaker knows a thing or two about wild parties, it’s Toyota! That’s why the 4Runner used to have a button that raised the bass and sent the sound to the rear of the car.

On the off chance you’re ever driving a DeLorean, it helps to know what the oddball “Lambda” light on the dashboard means. XBnMonaro breaks it down for us:

Notice that the the function of the light is not to monitor the operation of the engine or its emissions control system, but merely to remind the operator that the factory recommends that he service the engine.

It goes off every 30,000 miles to remind you to replace the oxygen sensor, or Lambda-Sond as it was called in Europe. Neat!

The fog light button looks confusing enough, but drivers in Europe have to worry about the one in the rear as well.

Extra what? According to the Saab Musuem, it’s for extra stuff you might want to add on later:

…..regarding the Extra button in the 99 (and also other Saabs) It was a button located in the panel [to be used] if the owner of the car wanted to add some electrical equipment to the car, like foglights etc. In Swedish we call [it] Extraljus. So we can say that it is a bit of Swinglish in our cars.

The button was also available off the shelf at our dealers if people wanted to have more in their Saab. We probably sold MANY of them in the good old times when the staus of the cars was connected to how many switches you had on the dashboard…..

Everyone knows what this light means, everyone dreads it, and everyone hates it. RazorGP explains this light’s biggest problem: from a diagnostic standpoint, it’s absolutely useless.

This cryptic fucker. It can mean anything from low washer fluid to your engine is 3 revolutions from mimicking a supernova and throwing its insides outside.
