Yellow or Orange
Pre-Collision System (PCS)
Automatic emergency braking is unavailable.
This symbol means your vehicle's Pre-Collision System, which uses sensors to detect potential frontal impacts, is not functioning correctly. The system has detected a fault and will not be able to assist with automatic braking or collision warnings until it is serviced.
What to do
- 01Check the front grille and windshield areas for any dirt, mud, or snow blocking the sensors.
- 02Turn the vehicle off and restart the engine to see if the error clears.
- 03Schedule an appointment at our shop for a professional diagnostic scan.
Other common causes
Common causes include misaligned radar sensors, a cracked windshield in front of the camera, damaged wiring, or a temporary software glitch.
How we check it
We perform a system scan to retrieve fault codes and verify that the sensors are properly calibrated and free of obstructions.
Symbols vary by make and model — always confirm in your owner's manual. If the light is red, the car feels different, or the light is blinking, stop and call us before driving further.
