When the set light on the car is on, it indicates abnormal tire pressure, and the tire pressure needs to be checked promptly. Its function is to adjust the tire pressure to the standard level. Press and hold the set button for three seconds while observing the speedometer. After hearing a beep, the tire pressure monitoring value will be calibrated accordingly. When there is abnormal tire pressure, a warning indicator will appear on the dashboard. Common knowledge for checking tire pressure safety: 1. Observe the tire condition before driving; 2. Pay attention to the friction sound between the tires and the ground while driving; 3. Be mindful of the cushioning force when driving on bumpy roads; 4. Regularly check and replenish the tire pressure; 5. Regularly clean particles and dirt from the tire surface.
When the SET light on your car comes on, it generally means your cruise control system has been set to a specific speed, which is particularly useful for long-distance highway driving. After pressing the cruise control button, the vehicle will remember the current speed, and the SET light will illuminate to remind you that the system is active. At this point, you don’t need to press the accelerator, as the car will automatically maintain the set speed. If the light comes on without any operation, it might be due to accidentally touching the control lever or a dirty/stuck button. Turning it off is simple—just lightly press the brake or press the cancel button, and the light will go off. Safety first: it’s recommended to use this feature in good road conditions, such as on highways with light traffic, and avoid using it in the city where distractions can lead to accidents. Regularly check your cruise control system to ensure it’s responsive and prevent accidental activation.
When the SET light comes on, it usually indicates that the cruise control mode is activated, locking the vehicle speed at your preset value. I accidentally triggered this function while driving in the city—the light turned on but the speed didn't change, which was quite annoying. Later, I found out from the manual that this is normal. It's best to use this feature only in open areas like highways to avoid sudden automatic acceleration. To deactivate it, simply press the brake pedal or hit the OFF button on the handle, and the light will disappear. If the light stays on but the system isn't functioning, it might be due to a faulty button or loose wiring—don't ignore it and get it repaired immediately. During routine maintenance, ask the mechanic to check this system to prevent any surprises on the road.
