Chevrolet Volt Warning Lights: What They Mean

Amber: check soon

Vehicle Ahead Indicator

Amber means you are following a vehicle ahead much too closely; green means a vehicle is detected ahead. PDF page 120

Other warnings and indicators

Airbag Readiness Light

Shows an electrical problem in the airbag system if it stays on after start or comes on while driving; airbags may not work properly.
What to do: Have the vehicle serviced right away. PDF page 114

Low tire pressure warning light

One or more tires has a significant loss of pressure. It may also flash then stay on if the TPMS has a malfunction.
What to do: Stop as soon as possible and inflate the tires to the pressure on the Tire and Loading Information label. PDF page 282

StabiliTrak OFF Light

StabiliTrak/ESC is turned off, which also turns off TCS, 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. If it does not come on briefly at start, have the vehicle serviced. PDF page 120

Traction Off Light

The Traction Control System has been turned off, so wheel spin is not limited. It also comes on with the StabiliTrak OFF light when ESC is off.
What to do: Adjust driving accordingly. If it does not come on briefly at start, have the vehicle serviced by your dealer. PDF page 120

Green: system on

ACC Indicator

Adaptive Cruise Control is engaged. It shows white when ACC is turned on but not engaged. PDF page 194

Regular Cruise Control Indicator

Regular cruise control is engaged; the following gap is not displayed.
What to do: Check which cruise mode is active before using it, since regular cruise will not brake for vehicles. PDF page 194

Summarized in our own words from the 2019 Chevrolet Volt 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.
