Can the CT5 use the key for one-touch window roll-up?

The CT5 can use the key for one-touch window roll-up. Operation method: The Cadillac CT5's one-touch window roll-up/down does not require additional settings. The key can be used to control the one-touch window operation. Press the lock button for three seconds, and all windows will automatically roll up; press the unlock button for three seconds, and all windows will automatically roll down. Smart key working principle: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit identifies the signal code, and then the system's actuator (motor or electromagnetic coil) executes the lock or unlock action. Press and hold the remote unlock button, and all four windows will automatically lower. Press and hold the lock button, and all four windows will automatically rise.
I've been driving the CT5 for almost a year now and found that the key can indeed lower all windows with one button. Holding down the unlock button will roll down the windows to release heat, which is very practical in summer. However, one-touch window closing doesn't seem to work. I've tried holding the lock button multiple times with no response, possibly to prevent safety risks from objects getting stuck. The CT5 windows have anti-pinch functionality - they'll automatically stop rising if they encounter an obstruction while driving or closing. But the remote window-closing feature has been restricted. You can use the window controls on the driver's door panel to close all windows with one touch after getting in the car, which is quite convenient. Although remote window closing isn't supported, understanding these details can help avoid confusion. I also recommend regularly checking the window seals for aging to prevent leaks or unusual noises.
As a CT5 owner, I often forget to close the windows during daily use. The one-touch function on the key allows the windows to automatically lower by holding the unlock button, which helps with quick ventilation inside the car. However, raising the windows relies on the controls inside the car. I've tried holding the lock button while locking the car with the key, but the windows didn't move, suggesting the CT5 might not have this feature designed. This could be due to safety regulations, as raising windows without attention might pinch people or pets. You can develop a habit of checking the windows before leaving or connect to the car's app to set up automatic window closing upon locking. By the way, remote window lowering is quite handy during rainy days or when parking, preventing rainwater from seeping in. In short, adapting to the existing features is the more reliable approach.
