Abstract: In a method of operating a telematics system, the presence or absence of an unauthorized access to a motor vehicle is determined by a control unit integrated in the motor vehicle. When determining the presence of an unauthorized access to the vehicle a functional unit, integrated in the motor vehicle and configured to operate an engine start of the vehicle and/or to unlock or lock the motor vehicle, is irreversibly deactivated by the control unit in response to the unauthorized access to the motor vehicle, and specified data about the unauthorized access is sent by the control unit to a vehicle-remote server of the telematics system.

Abstract: The invention relates to an additive for stabilizing a water-containing liquid hydrocarbon fuel, which comprises an alcohol of 5-10 carbon atoms, 0.5-3 parts by weight, calculated for 1 part by weight of said alcohol, of a carboxylic amide of 5-10 carbon atoms, and 3-10 parts by weight, calculated for 1 part by weight of said alcohol, of a carboxylic acid of 5-10 carbon atoms. The invention also relates to a stabilized liquid fuel for an internal combustion engine, which comprises 10-40% by weight of water, 45-85% by weight of a liquid hydrocarbon fuel, and 5-15% by weight of an additive as defined above, all percentages being calculated for the total weight of said liquid fuel.
