Emergency Brake Light

The hazard flasher system is activated as an additional emergency brake light in the case of emergency braking. Based on a defined delay value, the ABS module sends a signal to the IPC over the HS-CAN3 through the GWM. The IPC activates the hazard flasher system, which flashes 7 times.

Prerequisites for activation of the emergency brake light are:

• The speed is higher than 50 km/h (31 mph).
• The brake pedal is being actuated.
• The deceleration is greater than 9 meters per second squared.

To prevent activation on snow or ice, for example, the following prerequisites must be met:

• The speed is higher than 50 km/h (31 mph).
• The brake pedal is being actuated.
• ABS activation is taking place.
• The deceleration is greater than 6 meters per second squared.
