Pedestrian Detection Alert

Drive carefully to a mechanicTypically Red or Amber on the dash

Flashing red: a pedestrian is detected in your path — brake. Steady amber: the detection system is unavailable.

What it means

Camera and radar watch for pedestrians and cyclists ahead, especially at city speeds. An active red alert (usually with a chime, sometimes with automatic braking) means the car thinks a collision with a person is imminent. A steady amber light means the system is off or its camera view is blocked.

Can you keep driving?

An active alert demands immediate braking. A system-unavailable light means drive normally — you simply don't have the automatic backup; clean the windshield camera area.

What to do now

  1. 1

    Brake immediately on an active alert, then verify with your own eyes.

  2. 2

    Clean the windshield in front of the camera and the front emblem/radar area.

  3. 3

    Get persistent amber warnings scanned — especially after windshield replacement or front-end work.

Likely causes

  • Pedestrian or cyclist detected in the vehicle path (active alert)
  • Camera or radar blocked by dirt, snow, or glare
  • System fault or switched off

Typical fix cost

$0 to clean sensors; $300–$1,500 for camera/radar replacement and calibration

Ranges reflect mainstream US parts-and-labor pricing; your vehicle and region will vary.
