How to Use Cruise Control on the Buick LaCrosse?

[McLogan]

To activate the cruise control system on the Buick LaCrosse, simply press the cruise control ON button. Below are some important precautions regarding the use of the cruise control system: Use on Fully Closed Roads: In principle, cruise control should be used on highways or fully closed roads. On non-closed roads, complex traffic conditions can compromise safety, and frequent braking prevents maintaining a stable cruise control state, rendering the feature ineffective. Avoid Use on Roads with Excessive Curves: Disable cruise control on mountain roads or roads with numerous curves. In cruise control mode, the vehicle automatically maintains a constant speed, with the throttle controlled by the onboard computer, which can pose dangers when navigating curves. Do Not Use in Heavy Traffic or Poor Road Conditions: Never engage the speed control system when driving on roads with heavy traffic or poor road surfaces (such as slippery roads, loose gravel, or roads after heavy rain).
