Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driver Information
The Closing velocity module (CVM) sends information to the driver via text message, symbols and the indicator lamp in the Driver information module (DIM) (5/1).
The following text messages can appear in the Driver information module (DIM) :
- Message indicating that automatic braking has been requested by the Closing velocity module (CVM). The message remains until it is confirmed by the driver.
- Message indicating that there is a fault in one part of the support function City Safety . The function is switched off if the message appears in the vehicle.
- Message that the sensor on the windshield is blocked, for example, if a flag indicating long load on the roof hangs down in front of the sensor. From structure week 200835 the message also applies to forward-facing camera, connected to Forward Sensing Module (FSM).
