Chevrolet Silverado 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 135

Charging System Light

Comes on briefly at ignition as a check. If it stays on or comes on while driving, the charging system may have a problem.
What to do: Have it checked by your dealer; driving with it on could drain the battery. PDF page 135

Engine Coolant Temperature Warning Light

The vehicle has overheated. Driving with it on can damage the engine, possibly outside warranty coverage.
What to do: If it does not come on briefly at start, have the dealer service it. See Engine Overheating. PDF page 142

Antilock Brake System (ABS) Warning Light

ABS is not working if it stays on. With the brake system light also on, the regular brakes have a problem too.
What to do: Stop safely, turn the vehicle off and on to reset. If it stays on or returns, see your dealer. PDF page 139

Service Electric Parking Brake Light

Should come on briefly at start. If it stays on, there is a problem with the electric parking brake.
What to do: Take the vehicle to your dealer as soon as possible. PDF page 139

Low Tire Pressure Warning Light

One or more tires are significantly under-inflated. Flashing then staying on indicates a TPMS malfunction.
What to do: Stop as soon as possible and inflate tires to the pressure on the Tire and Loading Information label. PDF page 387

Electronic Stability Control (ESC) Off Light

ESC is turned off, which also turns off traction control, so the system does not assist in controlling the vehicle.
What to do: Turn on the TCS and ESC systems to turn the light off. PDF page 142

Trailer Sway Control Light (Uplevel Cluster)

Flashes when Trailer Sway Control is active. PDF page 142

Passenger Airbag Status Indicator

ON means the front passenger frontal airbag may inflate; OFF means the sensing system turned it off.
What to do: If both or neither light stay on after several seconds, see your dealer for service. PDF page 135

Four-Wheel-Drive Light

Shows the current drive mode; flashes while a shift is in progress and is steady once complete. PDF page 139

Summarized in our own words from the 2020 Chevrolet Silverado 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.
