Lincoln MKZ Hybrid Warning Lights: What They Mean

Other warnings and indicators

Low Tire Pressure Telltale

One or more tires are significantly under-inflated. Driving that way can overheat the tire, cause tire failure and hurt handling and fuel economy.
What to do: Stop and check your tires as soon as possible, and inflate them to the recommended pressure. PDF page 355

TPMS Malfunction Indicator

The tire pressure monitoring system is not working properly. It flashes about a minute, then stays on, and cannot signal low pressure.
What to do: Check the telltale after replacing tires or wheels, since replacements can stop the system working properly. PDF page 355

Service Engine Soon Indicator

The OBD-II system has detected an emission control malfunction, which may be temporary, such as running out of fuel or a loose fuel inlet.
What to do: If it stays on, have the vehicle serviced at the first opportunity. Blinking eight times at ignition-on means not ready for I/M testing. PDF page 192

Seatbelt Warning Lamp

The driver seatbelt is not fastened when the ignition is turned on; a chime sounds for a few seconds.
What to do: Buckle the driver seatbelt; the lamp and chime then turn off. PDF page 43

Auto Hold (ACTIVE) Indicator Light

Auto Hold is holding your vehicle stationary.
What to do: Press the brake pedal and the Auto Hold button to switch Auto Hold off. PDF page 205

Auto Hold (UNAVAILABLE) Indicator Light

Auto Hold is on but cannot hold the vehicle, for example during Active Park Assist, with seatbelt unfastened or door open. PDF page 205

Passenger Airbag Status Indicator (OFF)

The front passenger frontal airbag is disabled and will not inflate, such as when the seat is empty or a child restraint is detected. PDF page 51

Summarized in our own words from the 2020 Lincoln MKZ Hybrid 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.
