Zusammenfassung:	The invention relates to a method for determining safe start-up of a reducing agent provision configuration during relatively cold conditions. The method comprises the steps of determining a need of heating energy supply to the reducing agent provision configuration in order to provide safe start-up of the reducing agent provision configuration. This is performed on the basis of determined ambient temperature values corresponding to engine shut down and engine start as well as a determined time period during which the engine has been turned off.The invention relates also to a computer program product comprising program code (P) for a computer (200; 210; 500) for implementing a method according to the invention. The invention relates also to a system for determining safe start-up of a reducing agent provision configuration and a motor vehicle (100) equipped with the system.
