What does 'set' mean on a car display?
2 Answers
When 'set' appears on a car display, it refers to the speed setting switch, which is the cruise speed control indicator. To set the cruise speed, the driver accelerates the vehicle to the desired speed and presses the SET button. Typically, the vehicle speed must exceed 30 miles per hour for this function to work. When using cruise control, pressing the brake pedal will deactivate the cruise speed control. The 'set' function in a car also serves to confirm the standard tire pressure. After adjusting the tire pressure of all four tires to the recommended level, the driver should press and hold the 'set' button for three seconds while observing the speedometer. A warning symbol (an exclamation mark inside parentheses) will appear, and a beep sound will confirm that the tire pressure has been set according to the driver's adjustments. If a tire loses pressure during driving, causing incorrect tire pressure, the system will automatically trigger an alarm.
When I'm driving and see the SET indicator on the dashboard, it usually refers to the cruise control setting button. After pressing this button, the car will memorize the current speed and begin automatic cruising, eliminating the need to constantly press the accelerator. This is particularly helpful for long-distance driving, especially when maintaining a steady speed on highways. Remember that the vehicle speed must exceed 40 km/h to activate it. Once engaged, the system automatically controls the throttle, helping to save fuel, but you should disengage it in heavy traffic by simply applying the brakes. If the SET light is on but not functioning, the button might not be pressed firmly enough or the system might not be activated. Check the SET position on the steering wheel to ensure it's not stuck due to dust. Occasionally, the system may require a restart—turn off the engine and try again. Safe driving is more important, so avoid using cruise control in complex road conditions.
