Chevrolet Impala Warning Lights: What They Mean

Other warnings and indicators

Airbag Readiness Light

If it comes on and stays on, something may be wrong with the airbag system.
What to do: Have the vehicle serviced right away. PDF page 103

Charging System Light

If it stays on or comes on while driving, there may be a problem with the electrical charging system; the battery could drain.
What to do: Have it checked by your dealer. PDF page 103

Antilock Brake System (ABS) Warning Light

ABS has a problem. If only this light is on, regular brakes work but ABS does not. With the brake light also on, regular brakes have a problem.
What to do: Stop safely, turn the vehicle off and on to reset. If the light stays on or returns, see your dealer. PDF page 107

Traction Control System (TCS)/StabiliTrak Light

Steady light means TCS and possibly StabiliTrak/ESC are disabled. Flashing means the system is actively working.
What to do: Check the DIC messages to see which feature is not working and whether service is needed. PDF page 108

Traction Off Light

Traction control has been turned off, or StabiliTrak/ESC is off. Wheel spin is not limited.
What to do: Adjust driving accordingly. If it does not come on briefly at start, have it serviced. PDF page 108

StabiliTrak OFF Light

StabiliTrak/ESC is turned off, and TCS is also off, so the system does not assist in controlling the vehicle.
What to do: Turn TCS and StabiliTrak/ESC back on to turn the light off. PDF page 108

Passenger Airbag Status Indicator

ON means the front passenger frontal and knee airbags can inflate; OFF means the sensing system has turned them off.
What to do: If both or neither light stay on after several seconds, see your dealer for service. PDF page 103

Green: system on

Lane Departure Warning (LDW) Light

Green means LDW is on and ready. Flashing amber means the lane marking was crossed without a turn signal. PDF page 107

Vehicle Ahead Indicator

Green when a vehicle is detected ahead; amber when you are following much too closely. PDF page 107

Summarized in our own words from the 2020 Chevrolet Impala 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.
