It is a method for the aftertreatment of the exhaust gas of an internal combustion engine, in particular an internal combustion engine of a motor vehicle, proposed in which a liquid tool 25 stored for post-treatment in a reservoir 1, 31, if necessary, by means of removal means 3, 5, 7, 8 removed from the reservoir and exhaust gas-carrying areas 10 of the internal combustion engine is supplied, wherein the aid 25 before the time of filling the reservoir 1 with the aid 25 or in the case of a replaceable cartridge 31 as a reservoir before the date of connection of the reservoir 31 with the removal means 3, 5, 7 8 is offset with a freezing point lowering agent 26, the freezing point lowering agent 26 has no corrosive effect on the removal means 3, 5, 7, 8, which is stronger than a corrosive effect of the aid 25 on the removal means 3, 5, 7, 8 , |
