Method to adjust the headlights of the Envision: 1. The light control lever and the light adjustment knob can be seen in the driver's compartment; 2. Pushing the light control lever up or down activates the turn signals; 3. Pulling the light control lever forward or backward also activates the turn signals; 4. Turning the knob to the "AUTO" position enables automatic vehicle lighting. The 2019 Envision features a newly designed intelligent drag-reducing grille, aluminum roof rails, newly designed chrome dual exhaust pipes, 19-inch multi-spoke aluminum alloy wheels, and multi-function exterior rearview mirrors. The interior of the 2019 Envision continues to embody Buick's luxury concept, equipped with front-row multi-function seats, rear-row sliding seats with adjustable backrest angles, a large split central storage box, a heated steering wheel, a two-piece oversized panoramic sunroof, and an 8-inch HD touchscreen.
My friend asked me how to adjust the headlights on the Envision, and here's what I told him: First, locate the headlight position. After opening the hood, you can see white plastic gear knobs at the rear of the headlight assembly—usually two of them, controlling height and horizontal angle respectively. Prepare a Phillips screwdriver or hex key, and adjust it at night against a wall for the most accurate results. For height adjustment: Sit in the driver's seat, and aim for the light cutoff to be at the midpoint between the front of the car and the wall. Turn counterclockwise to raise the beam and clockwise to lower it. When adjusting the horizontal angle, be careful not to misalign it and affect oncoming traffic. Always test it on the road after adjustment. The knob positions may vary by model year, but you can find detailed diagrams in the manual. If you can't adjust it properly yourself, take it to a 4S shop and let the technicians use a laser calibrator.
