125000652 - N39 I.C.S. DETECTS INCORRECT POSITION

The Connect system detects an innacurate position Warning: The precise autoadjustment of the navigation system requires about 50 km operation at the first service and when the tyres are replaced with tyres of a different size.. If the wheel grip conditions are poor (for example slipping on ice), the system will temporarily give an incorrect position reading.
