The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected. The measure comprises supplying charge gas, which has recirculated exhaust gas, to the internal combustion engine during overrun operation. Also a capability check is carried out to detect conditions suitable for implementing the operating method.
