The cruise control switch for the Buick GL8 is located on the left side of the steering wheel, near the car emblem. Press the button to activate cruise control. Abbreviated as CCS, it is also known as a cruise control driving device, speed control system, or autonomous driving system. The cruise function will automatically deactivate when the brake lights are illuminated, which has led to the development of a new safety feature that activates if the brake circuit or brake bulb fails.

As a veteran driver who has driven the GL8 for many years, the cruise control is particularly useful on the highway. To activate it, first ensure the car is on a flat road and the speed is above 40 km/h—for example, if you want to set it at 80, steadily accelerate to 80 km/h. On the right side of the steering wheel, there are usually a few buttons: one with a dashboard icon labeled ON/OFF—press it to turn on the system (a light will illuminate on the dashboard); then press the adjacent SET button to lock the current speed. While using cruise control, use the + and - buttons for minor speed adjustments. To cancel at any time, either press the brake or the CANCEL button; to resume later, press the RES button. It’s recommended to use this feature only on well-maintained highways with good traffic conditions—avoid using it in congested city areas to prevent accidents. Also, regularly check the buttons during maintenance to ensure they don’t get stuck.

I just got a used GL8 and fell in love with cruise control—it's awesome to use! Here's how to operate it: Drive on a steady road and accelerate to your desired speed, say around 60 km/h. On the left or right side of the steering wheel, there's a small button cluster—press the ON switch to light up and activate the system. Then hit SET to lock it in immediately. This way, your foot can take a break from the accelerator, and adjusting speed with the +/- buttons is super convenient. To cancel, just tap the brake or press CANCEL. Don't panic when trying it for the first time—it's especially fuel-efficient and relaxing for long highway drives. Remember not to use it in rain, snow, or on winding roads. Get familiar with the button positions by practicing a few times.

Veteran GL8 drivers who make a living on the road will tell you: cruise control is a godsend for long trips. Just follow these simple steps: accelerate smoothly to over 40 mph; press the ON button on the steering wheel to activate the system; press SET to lock in your speed. Use the +/- buttons to adjust speed, and simply tap the brake to cancel. It's a huge convenience and fuel-saver on highways—but don't experiment with it in heavy traffic.
