Ford Explorer Warning Lights: What They Mean

Red: stop or act now

Brake indicator

Parking brake applied, low brake fluid level, or a brake system fault. Also lights briefly at ignition on as a bulb check.
What to do: If lit while moving, make sure the parking brake is released. If it is, see an authorized dealer. PDF page 234

Amber: check soon

ABS indicator

Anti-lock braking system malfunction. Normal braking continues without the anti-lock function. Flashing at any time also indicates a problem.
What to do: See an authorized dealer to have the system checked. PDF page 234

Low tire pressure telltale

One or more tires are significantly underinflated. If it flashes about a minute then stays on, the monitoring system has a malfunction.
What to do: Stop and check your tires as soon as possible and inflate them to the proper pressure. PDF page 439

Auto-start-stop indicator

Flashing amber with a message means you need to take action; the engine may restart automatically. Green means the engine is stopped by the system.
What to do: Follow the instrument cluster message. If the system malfunctions, have the vehicle checked as soon as possible. PDF page 192

Other warnings and indicators

Passenger airbag status indicator

The off lamp shows the front passenger frontal airbag is disabled; the on lamp shows it is enabled.
What to do: If the on lamp lights with a child restraint installed, switch off and reinstall the restraint. If an adult sees off, have them sit upright; otherwise ride in the rear. PDF page 64

Auto hold active indicator

Auto hold is applying the brakes to hold the vehicle at a standstill after a complete stop.
What to do: Press the accelerator and drive off normally to release the brakes. PDF page 244

Summarized in our own words from the 2026 Ford Explorer 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.
