Initializing Run Flat Indicator (RPA) (X5 M)

NOTE: Checking the tire pressure is based on speed monitoring 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 driving.

Initialization must be carried out in each case immediately after tire pressures have been corrected, after tires/wheels have been exchanged and after repair work to the air spring system.

Attention! 

The Flat Tire Monitor (RPA) is not operational when driving with a compact spare wheel.

Please refer to the Owner's Handbook of the vehicle for the initialization procedure.
