IMPORTANT:
- Use only BMW-approved two-part balancing weights.
- When fitting two-part balancing weights, always use specified tools.
- Do not straighten light alloy disc wheels: always replace damaged light alloy disc wheels.
- Notches in light alloy disc wheels can lead to cracking.
- Do not lubricate wheel nuts.
- When fitting tires, avoid damaging light alloy disc wheels, e.g. on sharpedged retaining claws on fitting machine.
INITIALIZING RUN FLAT INDICATOR (RPA)
NOTE: Checking the tire pressure is based on monitoring the speeds of the wheels in relation to each other. A tire puncture is detected and signalled by way of a deviation in specific speed ratios.
The four tires mounted on the vehicle are monitored while the vehicle is moving.
Initialization must be carried out in each case immediately after tire pressures have been corrected, after tires/wheels have been replaced and after repairs to the air spring system.
IMPORTANT: The Run Flat Indicator does not function when the vehicle is driven with the compact spare wheel.
Please refer to the relevant Owner's Handbook for details of the initialization procedure.
RDC RESETTING
NOTE: RDC monitors the tire inflation pressure in the four wheels.
Each tire incorporates an electronic wheel circuit, which constantly monitors the tire inflation pressure.
The system signals when the inflation pressure drops in one or more tires.
Resetting must be carried out in each case immediately after tire pressures have been corrected, after tires/wheels have been replaced and after repairs to the air spring system.
Please refer to the relevant Owner's Handbook for details of the resetting procedure.

Overview
The Dynamic Stability Control on the F01/F02 (DSC F0x) essentially
incorporates the same functions as on the
E70/E71 (DSC E7x).
As the DSC F0x is based on the same highly advanced technology as the DSC E7x,
all DSC functions on the
F01/F02 achieve outstanding performance in
