The distance until the DEF tank is empty can be viewed in the vehicle's instrument panel:
- Switch on the ignition. See SWITCHING ON THE IGNITION.
- Press the OK button repeatedly on the steering wheel control until Driver Assistance is displayed.
- Using the down arrow button on the steering wheel control, scroll down to highlight Vehicle Information.
- Press the OK button to confirm selection.

The instrument panel displays a series of messages when the DEF level gets low:
- The first message states that the DEF level is at a level where a top up is advised.
- The second message is accompanied by an AMBER warning icon and states to refill the DEF tank.
- The third message starts a countdown of the distance remaining until the DEF tank is empty, after which the vehicle will fail to start.
- The final message is accompanied by a RED warning icon and is displayed when the distance remaining is zero and states that no further restarts are possible until DEF is added to the tank.
