The distance until the DEF tank is empty can be viewed in the vehicle's instrument panel:

  1. Switch on the ignition. See SWITCHING ON THE IGNITION.

  2. Press the OK button repeatedly on the steering wheel control until Driver Assistance is displayed.

  3. Using the down arrow button on the steering wheel control, scroll down to highlight Vehicle Information.

  4. Press the OK button to confirm selection.

  5. Scroll down to highlight Next Service.

  6. Press the OK button to confirm selection. The Diesel Exhaust Fluid range is then displayed.
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.

We just drive our Discovery till it starts moaning it needs a topup, then put some in.
 
Sounds complicated.
