The level of DEF in the tank is checked via the Instrument Cluster (IC) menu. When selected the message center displays the approximate amount of DEF remaining, providing an estimated km/miles figure remaining, prior to emptying the tank

The DEF tank is fitted with combined temperature/ultrasonic level sensors. Circuit continuity and plausibility of the signals received are checked within the ECM. An ultrasonic "no echo malfunction" is set if no valid echo from the ultrasonic sensor is detected during a predefined time. This typically happens when the ultrasonic signal of the sensor is blocked, or if the DEF tank is overfilled (the air pocket at the top of the DEF tank is no longer present). The vehicle message center display's an advisory/warning system, which activates in low DEF conditions. If no corrective action is made, the engine will eventually not restart. The stages in the warning system are listed in the following tables

NOTE: None of the listed stages will activate the MIL. The stages are automatically cleared if the DEF level is increased
