Visuals & Meaning of ADAS Lights
ADAS lights typically appear in one of three colors, each conveying a different level of urgency:
- Green / Blue: Indicates a system is active and operating correctly—such as Adaptive Cruise Control (ACC) or Lane Keeping Assist (LKA). These lights are a reassuring confirmation that the system is engaged and functional.
- Yellow / Amber: A cautionary signal. It indicates that a system—like Forward Collision Warning or Lane Departure Warning—detects a potential issue. Attention is advised, but immediate action may not yet be critical.
- Red: A serious safety warning. Lighting up in red, these lights signal that an ADAS component may not be working correctly and requires prompt inspection to ensure the vehicle’s safety systems are fully operational.
Common ADAS Dashboard Icons
Here are some typical symbols and what they represent:
- Steering Wheel with Lane Lines: Represents Lane Keeping Assist or Lane Departure Warning, often depicted in green when active or amber/red when there’s a fault.
- Car with a Radar Beam: Indicates Adaptive Cruise Control functioning; a change in color or illumination may signal a calibration issue.
- Car Approaching Another Car or Pedestrian: Common for Forward Collision Warning or Automatic Emergency Braking—warns you of front-end obstacles or malfunctions.
- Exclamation Mark in Steering Wheel or Warning Circle: Alerts to significant ADAS malfunctions. Similar to power steering warnings, they can be red or amber and should be taken seriously
Why These Lights Matter
ADAS dashboard lights are your car’s way of communicating system status and health:
- Green/Blue = System is active and performing as expected.
- Yellow/Amber = Issue detected; schedule service soon to avoid downtime.
- Red = Critical malfunction; prompt professional attention is essential for your safety.
Ignoring these lights can compromise vital safety systems like collision avoidance, adaptive braking, and lane guidance.
