New System Features/Modifications

The main feature of the instrument cluster in the Z4 is its new design:

• The indicator and warning lamps between the needle instruments. The coolant temperature gauge and the fuel gauge are integrated in the tachometer.
• Additional indicator and warning lamps (e.g. Electric Power Steering EPS) are integrated.
• The automatic gearbox or Sequential Manual Gearbox SMG has a liquid-crystal display for indicating the gear.
• The instrument cluster of the Z4 has a gateway function between the bus systems (as in the E46) K-Bus, PT-CAN Bus and diagnosis bus.
• The lighting of the instrument cluster is controlled by means of the K-Bus.
• The instrument cluster has a modified voltage supply with undervoltage detection.
• The acoustic alarms and test functions have been expanded.
