What does the hold button on a car key represent?

The hold button on a car key means long-press to open the trunk. Here is some related information about the hold button: 1. On the remote key, it means to hold, which is different from unlocking and locking the car. Opening the trunk is only necessary when the car is parked. The function of long-pressing the hold button for a few seconds to open the trunk is to avoid the danger of accidentally opening the trunk while the car is moving. 2. Remote start allows you to adjust the interior temperature in advance. In winter, you can warm up the car beforehand, ensuring the engine temperature is normal when you get in, avoiding idling waits or engine wear due to low temperatures. The remote control range is usually no less than 50 meters, allowing you to start the car remotely from home or work. With an automatic timer function, if the car door is not unlocked within a certain time, the engine will automatically shut off. Using the hold button for remote start can significantly save the owner's time and enhance driving comfort.
I've driven quite a few cars with the HOLD button, which is mainly for remote engine start. Last time when it was minus ten degrees Celsius while taking my kid to school, I held the HOLD button for two minutes in advance, and the car warmed up by itself. When I got in, the steering wheel was already warm. Some American cars can even turn on the air conditioning to defog at the same time, which is especially useful when parking outdoors in summer. However, it's important to note that the doors remain locked after starting, and you need to press the unlock button again to open them. When I first bought the car, I didn't read the manual and pressed the button without any response—turns out I didn't press the brake while using the key. Later, I learned that certain conditions like being in P gear must be met for it to work. This button is a lifesaver in winter for preheating the car, no more shivering while waiting for the engine to warm up.
My old American SUV key has a small round button labeled 'HOLD' that activates remote start when pressed. Last year during a self-drive trip in Northeast China at minus twenty degrees Celsius, I would press it by the hotel window before heading out each day, and three minutes later, I'd go downstairs and drive off directly. Once I noticed that holding it down made the turn signals flash three times, the engine would roar to life, and even the steering wheel heater would turn on automatically. However, safety rules must be observed: if the car detects an unclosed door or a nearly empty fuel tank, this function won't work. Last time, a friend almost got locked outside because the engine automatically shuts off after ten minutes of inactivity after remote start. To extend the time, just press the HOLD button again.
