Rear radar system indicators

Rear radar system

These are Rear Radar System Indicators symbols from Volvo. A green indicator simply means that the system is active and working normally. If, however, there is a fault with the rear radar system, the red symbol will appear. A flashing symbol means there is a calibration failure.

  • Otherwise, you can return to our main Manufacturer Symbols pages and scan again!

The vehicle has several ways to identify objects that are in or approaching the reversing path, including the rear radar system, which can detect traffic approaching from the sides. If the separate Rear Auto Brake function is enabled, the vehicle may intervene by braking to prevent or mitigate a collision.

The vehicle deactivates the rear radar units if a trailer is connected. Towbar-mounted accessories that are not connected electrically to the vehicle does not disable the rear radar units but can obstruct them.

Blind spot information also relies in part on detection by the rear radar units and the symbols are very, very similar. The second vehicle is further behind. Do not confuse them. Click here for more on Blind Spot Detection,
