[VanLevi]

The one-touch window roll-up function allows the car window glass to be controlled to roll up or down with a single press. The activation steps are as follows: 1. First, close the car door and turn on the ignition switch to test if each window rolls up and down normally; 2. Start by setting the driver's door window. Press and hold the left front door window button to roll it up to the top; 3. After reaching the top, continue holding the button for more than 3 seconds; 4. Release the button after 3 seconds and test if the one-touch window roll-up function is successfully set; 5. Generally, it succeeds in one attempt. If not, repeat the operation; 6. Set the other three door windows in the same way.
