GL8's rear door behind the driver is manually operated, while the door behind the front passenger is electric with four opening methods: first, there is an opening switch near the sunroof controls; second, a button switch is located on the B-pillar above the front passenger seatbelt; third, it can be opened from inside the middle door via the interior handle; fourth, it can be opened using the button on the remote control. Below is more information about the GL8: Exterior: The new generation Buick GL8 Avenir family has body dimensions of 5219mm × 1878mm × 1799mm, with a wheelbase of 3088mm. Powertrain: The new generation Buick GL8 family is equipped with General Motors' latest Smart Propulsion technology, featuring a powerhouse combination of the eighth-generation Ecotec 2.0T variable cylinder turbocharged engine and a 9-speed HYDRA-MATIC intelligent transmission, delivering robust performance of 174kW and 350Nm, with a combined fuel consumption of only 7.9L/7.8L per 100km.

I've been driving the GL8 for five years, and the door opening button is usually right on the driver's side, within easy reach. The most common location is below the left side of the steering wheel, in the corner of the dashboard—it's a small button with a door icon. Just press it lightly, and the sliding door opens automatically, which is super convenient. If you're a newbie, it might take a few tries to get used to it, but the placement is quite user-friendly and not too far off to the side to be hard to find. Additionally, the button on the electric door version responds quickly and is easy to press, especially in tight parking spots or on rainy days—no need to open the door to pick someone up. Sometimes, with older GL8 models, you might find the button on the door handle, requiring a pull on the inner side of the door. Remember to clean the button regularly to avoid dust buildup; over time, it might develop poor contact—I've had that happen before. Getting the wiring checked during maintenance can help prevent malfunctions.

For regular GL8 users, the door opening button is not hard to locate. There's usually a small button in the lower left corner of the dashboard on the driver's side—press it and the door opens. It's straightforward: stop the car and press the button. If it doesn't respond, it might be a blown fuse or an electrical issue; a quick check of the fuse box can help. Some higher-end models integrate the button into the central touchscreen, but most still use a physical button. I also recommend avoiding excessive force when pressing the button to prevent wear. Compared to other vehicles, the GL8's design is thoughtful, making it easy for family members to get in.

The GL8 door opening button is usually located under the instrument panel on the left side of the driver's seat, in a clearly visible and easy-to-operate position. A single press opens the middle door, making it convenient for daily use. There might be slight variations in position across different models, but it's generally in this area. New users will get accustomed to it after a few tries.
