The strangest buttons on cars
Many cars, especially luxury cars, have different features, so they have strange buttons and switches that not many people know about.
"PTY/CAT" button on Subaru vehicles
PTY/CAT stands for “Program Type” and “Category”. The function of this button is to cycle through the settings and music genres in the car's playlist.
"BC" button on BMW turn signal lever
The function of this button is to cycle through the different settings on the display screen. Many people complain that they often press this button by mistake when they want to turn on the turn signal.
The "FUNK" button on Volkswagen and Audi cars
FUNK is German for radio, and for police cars and taxis this button turns off the radio.
The "horse" button on the Ford Mustang
On the steering wheel of the Ford Mustang there is a button with a horse symbol, next to the phone and music buttons. That is the horse symbol of the Ford Mustang line. When this button is pressed, the car's instrument cluster will display many parameters related to the car's high-performance mode.
Lexus door opener button
This button appears on the Lexus LX 570. At first glance, it looks like it depicts a person getting into the car. In fact, this button controls a function called "Easy Entry and Exit". If you press this button on the LX 570, the suspension will lower a bit to make it easier for you to get in next time.

The three-noodle button on the Mercedes-Benz Sprinter
The Mercedes-Benz Sprinter has a small button next to the steering wheel that looks like three noodles and a plus sign. This button actually controls something called a “heater,” which is designed to help the Sprinter’s engine warm up faster if the vehicle is in a cold climate. You can also use the heater while driving to ensure the engine stays at the optimal temperature.
Green circle button on Infiniti car
New Infiniti models feature a button on the steering wheel that looks like a car surrounded by blue circles. This confusing button activates Infiniti's "ProPILOT" system, an autonomous driving system that can steer and control the car for short periods of time before requiring the driver to intervene.

DNA button on Alfa Romeo
When you get into the cabin of an Alfa Romeo Stelvio or Giulia, you will be curious to see a knob with 3 letters d, n, a. If you are an Alfa Romeo car expert, you will understand that this is an abbreviation for 3 English letters Dynamic (Sport), Natural (Natural) and All-Weather (All-Weather).
Audi windshield knob
If you drive a high-end Audi, you'll notice that the headlight switch panel has a strange silver knob that looks like a windshield. This is actually the knob that controls the head-up display: turning it left/right will increase or decrease the brightness, while pressing it will turn it on or off.
Pickup button on Honda Ridgeline
The Honda Ridgeline has a strange button below the gearshift that has a picture of a pickup truck driving on a rough road. According to Honda, this button controls the traction control system for the Ridgeline’s four-wheel drive system. The system allows the driver to choose the mode they want: road, snow, mud, or sand.
Kia car star button
On many high-end Kia models, there is a button near the infotainment system with a star on it. It is located right next to the "RADIO" and "MEDIA" buttons, both of which have obvious functions, but the star button does not. The star button is actually a customizable button for the driver. The user can set it to perform any function, such as bringing up a frequently used screen.
Home arrow button on Mercedes-Benz G-Class
The new Mercedes-Benz G-Class is a big improvement over the old model, including the Home button with a little arrow on it. The function of this button is pretty straightforward: It brings the instrument cluster display back to the main interface if the user gets lost in the various sub-screens. What's confusing is that it's placed next to the cruise control buttons.

H2O button on Toyota Mirai
The Toyota Mirai is a hydrogen fuel cell vehicle, meaning its only waste product is water. So it's no surprise that we see a water-related button on the car. When you press this button, the car opens a small tube that allows water to flow onto the road. The Toyota Mirai is capable of automatically draining the water if needed, but you can also manually activate this feature with the push of a button.
