How to Use the Active Braking System on the Envision?

[Eileen]

The method to use the active braking system on the Envision is: The active braking does not require any setup; it automatically activates upon starting the vehicle. Active braking refers to the vehicle's capability to autonomously identify obstacles, assess the possibility of a collision, and decide whether to execute automatic braking based on the feedback results. Taking the Envision 2021 model as an example, its body dimensions are: length 4694mm, width 1839mm, height 1686mm, with a wheelbase of 2750mm and a fuel tank capacity of 66 liters. The Envision 2021 model is equipped with a 1.5T turbocharged engine, delivering a maximum power of 124kW and a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.

The active braking system in the Envision is an automatic function that does not require manual activation. It will automatically engage during driving whenever the system detects a collision risk. When sensors identify an obstacle ahead and the driver fails to respond promptly, the vehicle will first issue warnings through flashing red dashboard alerts and audible beeps. If the driver still does not brake, the system will automatically apply braking force to prevent or mitigate a collision. I recommend checking whether the millimeter-wave radar in the front grille and the windshield camera are obstructed by dirt before driving, as sensor malfunctions can cause the system to fail. Be especially cautious during rainy or foggy conditions, as the active braking system's recognition capability decreases in low visibility. Keeping the vehicle's software up to date is also crucial—remember to have the dealership check the advanced driver-assistance system (ADAS) module during maintenance visits.

As a regular Buick Envision driver, I've found that the automatic emergency braking doesn't require manual activation - the system remains on standby during normal driving. Its core technology relies on a combination of front radar and camera monitoring obstacles within 150 meters ahead. If you follow too closely or a pedestrian suddenly darts out, warning alarms will sound first, followed by automatic brake pedal depression for emergency stopping. Note the speed limitations though - full functionality activates only above 30km/h, so it might not trigger during low-speed traffic jams. I recommend disabling auto start-stop in daily use because the system briefly deactivates during engine restart cycles. Regular cleaning of front sensor areas is crucial - once after a long trip when I didn't wipe the radar cover, the system gave several false alarms.

The Envision's automatic emergency braking operates fully autonomously and activates by default upon ignition. While driving, it continuously scans the road through the windshield camera and will automatically apply brakes upon detecting collision risks. The only manual operation required is confirming the function's activation status via the steering wheel button settings menu. This feature effectively prevents rear-end collisions during urban driving, but two cautions apply: 1) Braking may be falsely triggered when crossing speed bumps or rough road surfaces, and 2) The camera may malfunction under intense backlighting. Monthly cleaning of the front radar cover with a damp cloth is recommended. If the system alarm sounds, remain calm and maintain steering control.

I found the active braking system on the Envision most practical in highway scenarios. This system requires no additional driver input, but three key points should be noted: it only activates when speed exceeds 15km/h; alert sensitivity can be adjusted via the central display - beginners should set it to the highest level; rear active braking operates independently during reversing - exercise caution when yellow markers appear on the reversing camera. After heavy rain, remember to dry the front sensor area - my vehicle once mistook rain curtains for obstacles and triggered sudden braking. Before long trips, perform a system self-check by running the diagnostic program in the instrument cluster's vehicle settings.

The Envision's automatic emergency braking is like an invisible co-pilot - you don't notice it normally but it can save lives in emergencies. It operates automatically throughout the journey, using radar waves to detect the movement trajectory of objects ahead. When the system determines a collision is unavoidable, seatbelts will pre-tighten and lock, followed by full-force braking. However, there are some situations to note: for example, when a vehicle ahead suddenly changes lanes, the system may respond with some delay; detection distance decreases when driving on curves or slopes. It's recommended to have the radar angle calibrated at the 4S store every spring. I personally also disabled the auto-hold function on the center console screen, which makes the braking force more linear when the automatic emergency braking intervenes.
