Warning lights

Lane departure / lane keeping light

Steady: the lane system is on or cannot see the lane markings. Flashing: you are drifting out of your lane.

Urgency:Safe to keep driving

Is it safe to keep driving?

Yes. If the system reports itself unavailable, it usually means the camera cannot read the road — dirt, rain, snow or faded markings.

Likely causes

  • Dirty windshield in front of the camera
  • Poor or missing lane markings
  • Camera calibration off after a windshield replacement

Typical repair cost (US)

$0 – $400

Free if cleaning the windshield fixes it; a camera recalibration at the high end.

A typical range, not a quote. Actual cost depends on the car, the shop and the fault.

What to do now

  1. Clean the windshield around the camera.
  2. If it stays unavailable in clear conditions, the camera may need recalibrating.
