How to One-Touch Control Window Roll-Up/Down with Car Key?

[DiDelilah]

Press the button to the first detent position, then release when the window reaches the desired position. Apply slightly more pressure to press to the second detent, and the window will automatically roll down. Pull the switch up to the first detent and hold until the window moves to the required position. Apply slightly more force to pull the button to the second detent, and the window will automatically roll up.

I found this feature quite handy after buying the car. Holding down the unlock button on the remote key can roll down the windows, while holding the lock button can roll them up. It's very convenient for ventilating the car before getting in during summer, and you don't need to rush back to the car in the rain if you forget to close the windows. However, some older models require setup to activate this function—you need to find the window settings option on the central control screen and check the box to enable it. If the remote distance becomes shorter or unresponsive, it's likely time to replace the key battery. You can buy a coin cell battery and replace it yourself; just check the model number on the back of the key. Also, be careful not to close the windows when there are branches on the roof, as it can jam and damage the motor.
