What does the car remote control hold mean?

[ReidRose]

Car remote control hold button means long press. The hold button with a trunk pattern indicates that long pressing will open the trunk, simplifying the process of opening the trunk. Another function of the hold button is as a remote engine start button. Pressing and holding the hold button for 2 to 3 seconds within the remote distance can automatically start the car. The hold button can also pre-adjust the interior temperature. In summer, setting the air conditioning temperature before getting off the car allows remote start to cool the interior in advance. In winter, it can warm up the car in advance, so the engine temperature is normal when getting in, avoiding idling wait and engine wear caused by low temperature.
