How to activate cruise control on the Buick GL8?

[StAsher]

To activate cruise control on the Buick GL8, follow these steps: 1. When the vehicle speed reaches above 40 km/h, turn on the cruise control switch, then press the deceleration button. 2. Drive according to the set speed, and press the deceleration button again to engage the cruise function. To deactivate, simply step on the brake pedal, which will automatically disengage the system. The working principle of the cruise control system is as follows: 1. The cruise control module reads the pulse signal from the vehicle speed sensor and compares it with the preset speed, then issues commands to the servo mechanism to adjust the throttle opening, increasing or decreasing it to maintain the set speed. 2. The electronic multi-function cruise control system eliminates the mechanical control parts of the cable-type cruise control, adopting precise electronic control instead, which ensures more accurate control and avoids the risk of mechanical failures.
