Cadillac CTS and CTS-V Warning Lights: What They Mean

Amber: check soon

Antilock Brake System (ABS) Warning Light

Antilock brakes are not working. If the brake system light is also on, the regular brakes have a problem too.
What to do: Stop safely, turn off, restart to reset. If it stays on or returns, have the vehicle serviced. PDF page 133

Other warnings and indicators

Charging System Light

If it stays on or comes on while driving, there may be a problem with the electrical charging system. PDF page 129

Passenger Airbag Status Indicator

ON means the passenger airbags can inflate; OFF means the sensing system turned them off. Both lit or neither lit suggests a problem.
What to do: If both or no lights stay on after several seconds, see your dealer for service. PDF page 129

StabiliTrak OFF Light

StabiliTrak/ESC is turned off, which also turns TCS 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 134

Traction Off Light

Traction Control System has been turned off, so wheel spin is not limited.
What to do: Adjust driving accordingly. PDF page 134

Green: system on

Lane Keep Assist (LKA) Light

Green: LKA is available. Amber: LKA is assisting; flashing amber is a Lane Departure Warning that a lane marking was crossed. PDF page 133

Vehicle Ahead Indicator

Green when a vehicle is detected ahead; amber when following a vehicle much too closely. PDF page 133

Summarized in our own words from the 2019 Cadillac CTS and CTS-V 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.
