Collision Mitigation Brake System Indicator

Collision Mitigation

This is the Collision Mitigation Brake System (CMBS) Indicator symbol. It is a radar-based system that can warn a driver of a potential collision or even apply the brakes on its own to prevent one. These systems are all moving in the direction of automatic braking, which all manufacturers have promised to install in all passenger vehicles by roughly 2020.

  • Before moving on, are you sure this is your symbol?? If yes, then continue on below.
  • Otherwise you can return to our main Text Symbols page and scan again!

The light comes on if the system has been turned off, if the radar sensor is dirty or blocked, or if there is a fault in the system. In the second case, a simple car wash may restore the system’s function. In the last case, take the vehicle to your dealer or authorized service center for diagnosis and repair.

These systems continue to evolve. Click this link for more on Collision Avoidance and Auto Braking systems. This link goes to yet another related system with an entirely different name, Intelligent Brake Assist.
