Can Zilong's front radar be set to always be automatically on by default??? I couldn't find where to set it up.

It seems like all cars are designed this way. To activate the front radar, you need to press the radar button separately. [I just want to be quiet]

When driving, you have to manually press the button to turn it on; by default, it's off.

Yes, there is. Next to the mirror adjustment on the left side, there's a button that looks like a mobile signal. Press it to turn it on, and it will stay on. When you're at a red light and the car behind you gets too close, it will beep as an alert. It's a bit annoying.

Once you activate cruise control, it will engage.
