CT5 cannot close windows with the key. This model only supports opening the vehicle's windows via the remote key. To close the windows, you must use the door switches or operate them independently from the driver's door, which is not very convenient. Below is some related information about the CT5: 1. Body dimensions: The full range of models has a body length of 4924 mm, width of 1883 mm, height of 1453 mm, wheelbase of 2947 mm, front track of 1596 mm, rear track of 1634 mm. The vehicle is a four-door, five-seat sedan with a fuel tank capacity of 66 liters and a trunk capacity of 384 liters. 2. Manufacturer: The manufacturer is SAIC General Motors Chevrolet. The company, Shanghai General Motors Co., Ltd., was established on June 12, 1997, as a joint venture between China's SAIC Motor Corporation Limited and the American General Motors Company. Besides the Buick brand, the company also owns the Cadillac and Chevrolet brands.

I previously drove a CT5 for a while, and this car indeed supports closing the windows with the key, which is very convenient. The specific operation is to press and hold the lock button on the key for a few seconds, and all four windows will automatically roll up and close. I think this feature is particularly useful on rainy or hot sunny days. For example, if you realize the windows aren't fully closed after getting out of the car, you don't need to go back—just handle it remotely from a distance. However, it's important to note that there might be slight variations between different model years, so you should check the owner's manual to confirm that the comfort access feature is activated. I recommend keeping the key battery charged and cleaning the buttons regularly to prevent malfunctions. Another related point is that the CT5 may also support remote window closing via an app. If you don't have the key with you, you can still operate it from your phone, but you need to subscribe to the corresponding service. In short, this is a basic feature in modern cars—test it out to ensure the settings are correct and avoid accidents. I've encountered a few instances where the buttons became sticky after prolonged use. If the windows won't close, take it to the dealership to check the wiring or refresh the system.

My CT5 is the 2022 model, and it can fully close the windows using the key fob. The operation is very simple: just press and hold the lock button for about 3 seconds, and all the windows will roll up. This feature is fantastic for a tech enthusiast like me—it's integrated into the keyless entry system, showcasing Cadillac's intelligent design. Besides closing windows, the key fob can also remotely operate the sunroof or start the vehicle. When combined with the mobile app, it becomes even more powerful, offering remote temperature adjustment, door locking, and more. Just remember, the default settings might require activation—simply go to the vehicle settings menu and enable the 'Remote Window Close' option. I once experienced sluggish response when the key fob battery was low, but replacing it fixed the issue. On a related note, some modified cars can have similar modules installed afterward, but the factory version is more reliable. I often recommend friends to confirm this feature when purchasing a car—it's both safe and convenient.

My experience with the CT5 is that you can close the windows using the key fob, which is correct. Operationally, just press and hold the lock button on the key fob for a few seconds, especially useful when rushing out of the car. As a family car user, I often teach my wife and kids this trick to prevent seats from getting wet in the rain or to deter thieves, which is quite important. However, in practice, if the key fob isn't responsive, the windows might not close completely, so it's necessary to check if the buttons are damaged or have too much dust. Another aspect is safety: avoid accidentally pressing the key fob while driving, as it could cause the windows to suddenly close. Regular maintenance of the key fob, including checking if the settings have this function enabled, is advisable. The CT5 system usually has this preset, but if there's an issue, take it to a professional shop to fix the wiring or update the software.
