Buick Verano Warning Lights: What They Mean

Red: stop or act now

Brake System Warning Light

Comes on with the electric parking brake when applied, or when there is a brake problem. Brake pedal may be harder or go lower.

Amber: check soon

Electrical problem in the airbag system. If it stays on or comes on while driving, airbags might not work properly.

Summarized in our own words from the 2017 Buick Verano owner's manual (AI-assisted; every light name was matched against its cited page 2026-10-18). Your vehicle may not have every light, and other years can differ. A red warning that stays on usually means stop safely and check: your manual has the final word.
