Blind Spot Monitor Warning or System Symbols

Blind Spot Monitor

These are Blind Spot Monitor (BSM) Warning or Blind Spot Detection (BSD), Blind Spot Alert (BSA) System (left) or BLind spot Information System (BLIS) (right) or Blind Spot Intervention (BSI) symbols. Yet another instance of essentially identical systems end up with manufacturer-dependent names for reasons that are not at all clear.

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

The light or symbol, often seen on the far corners of outside mirrors themselves, will illuminate when a vehicle is detected in the blind spot. Also seen on mirrors are simple yellow/amber lines in many models.

The light will flash while the turn signal is operated. Manufacturers who employ the light on the instrument panel also employ an indicator lamp on the inside of the mirror to draw attention to side of the vehicle being intruded upon.

The systems monitor the areas on either side of the vehicle just behind the driver and front passenger for unseen vehicles and obstructions. The indicator lights look like vehicles pointing a beam at another vehicle, which is pretty much what it is doing.

Note that these systems are evolving to active duty. That is, if an obstructive is detected in the area covered, the vehicle will move itself out of the way (Blind Spot Intervention above).

Many More Versions

System problems are generally indicated by a separate alert and text message in the instrument panel. These may include the Blind Spot Alert Malfunction indicator at the left. The word OFF added to the image means that the option has been switched off or has malfunctioned. The last two also indicate a malfunction one in red and the other with a line through, but still in yellow/amber/orange. A malfunction will not effect any driving systems, so you may continue on your way. Blind Spot Monitoring will not be available, however.

This version displays only the sensors used for blind spot detection. If seen in black and white, as shown here, the system is unavailable, likely because the sensors are dirty. A text message will be seen with the symbol in the information screen. If the system is working properly, the symbol will be displayed in green.

Alternatively or in conjunction with the symbols above, text symbols with the acronym BSM, or Blind Spot Monitor, or BSM OFF, may be seen on the instrument panel. BSM alone in green simply indicates the system is on. On of the symbols above will be seen in the outside mirrors themselves.

BSM alone and in yellow/amber indicates a problem with the system. If on continuously, BSM OFF indicates the system has been turned off. If flashing, BSM OFF indicates a problem with the system. See your dealer or authorized service center for repairs. The vehicle can be driven without the benefit of the advanced system.

This one is used by Audi. It may be the clearest concept, in that it is the image of a car in a mirror! It is the Audi Side Assist Indicator, and, if seen, regardless of color, points to a fault in the system.

However, in black and white, it may also simply indicate that the system is unavailable. It may reset on re-start, or may need sensors to be cleaned..

When the light is on and stays on, the assist system is inoperative and will not detect vehicles alongside your car. Find a dealer or authorized repair station soon.

Some manufacturers use an indicator in gray scale is seen when the system is activated. It uses large triangles on either side of an image of a vehicle to show the area covered by sensors. If there is a system problem, a text message will appear. Both are seen in the center information display.
