Buick Encore GX Warning Lights: What They Mean

Red: stop or act now

Airbag Readiness Light

If it comes on and stays on, something may be wrong with the airbag system, so airbags might not inflate in a crash or could inflate without one.
What to do: Have the vehicle serviced right away to help avoid injury. PDF page 104

Amber: check soon

All-Wheel-Drive Light

The light shows when All-Wheel Drive or Front-Wheel Drive mode is selected. If it displays amber, there may be a malfunction.
What to do: See your dealer. PDF page 108

Lane Keep Assist (LKA) Light

Flashing amber is a Lane Departure Warning that a lane marking was unintentionally crossed. White means unable to assist; green means on and ready to assist. PDF page 108

Other warnings and indicators

Passenger Airbag Status Indicator

ON means the front passenger airbag and knee airbag can inflate; OFF means the sensing system turned them off. Both lit or neither lit suggests a problem.
What to do: If both or neither are lit after several seconds, see your dealer for service. PDF page 104

Automatic Emergency Braking (AEB) Disabled Light

Automatic Emergency Braking or Front Pedestrian Braking is turned off, or unavailable due to malfunction, weather, or a dirty windshield. PDF page 108

Summarized in our own words from the 2026 Buick Encore GX 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.
