What is the SET button in a car for?
1 Answers
The SET button in a car stands for speed setting switch, which is a cruise speed control indicator. When you want to set the cruise speed, accelerate the car to the desired speed and press the SET button. Here are the relevant details: 1. Function: Its main function is to set the standard tire pressure for all four tires. After adjusting the tire pressure to the standard level, press and hold the SET button for three seconds while observing the speedometer dial. A warning symbol (an exclamation mark inside parentheses) will appear, and upon hearing a beep sound, the system will calibrate the tire pressure for all four tires based on the adjusted values. If a tire loses pressure during driving, the system will automatically trigger an alarm. 2. RES: The corresponding button to SET is RES. The RES button has two functions: one is to accelerate when cruise control is set, and the other is to resume the previously set speed after temporarily canceling the cruise control.
