Land Rover Discovery: Running out of fuel

Avoid running out of fuel.

If the vehicle does run out of fuel, a minimum of 4 litres will be required to restart the engine.

The vehicle should be left with the ignition on for 5 minutes after refuelling, before attempting to restart the engine.

The vehicle will need to be driven for a distance of 1.5 - 5 km, in order to reset the engine management and monitoring systems.

Running out of fuel

Some vehicles with a diesel engine are supplied with an active misfuelling device, i.e., a visible metal flap in the filler neck.

These vehicles will require the use of the emergency funnel supplied with the vehicle, to refill the fuel tank with a fuel can. Insert the funnel into the filler neck, fully and squarely to open the active misfuelling device.

Note: If the vehicle does run out of fuel, seeking qualified assistance is advisable.


If the warning WATER IN FUEL SEE HANDBOOK is displayed in the Message centre, an excessive amount of water has collected in the fuel filter bowl. Seek assistance from a Retailer/Authorised Repairer, to have the fuel filter bowl drained as soon as possible.


Vehicles with a diesel engine are equipped with a system to prevent the fuel tank from emptying completely, which would then draw air into the fuel system. When the fuel reaches a minimum level, the system will activate a reduced power mode (i.e., the engine will not run properly). This will be followed by the engine stopping in approximately 1.6 km.

This feature prevents the fuel system from running dry, which could cause damage to the vehicle. If the gauge indicates low fuel or the warning indicator illuminates, the fuel tank should be refuelled as soon as possible, with at least 4 litres of fuel.

If the system protection function has activated, the vehicle must be refuelled, then restarted using the following procedure:

  1. With the brake pedal pressed, press and hold the engine START/STOP button and crank the engine for 5 seconds.
  2. Release the START/STOP button.
  3. With the brake pedal pressed, press and release the START/STOP button to crank the engine. The engine should start within approximately 5 seconds.

Note: If the engine does not start, pause for 10 seconds with the ignition in Convenience mode, before repeating the procedure from the beginning.

Do not crank the engine for longer than 30 seconds continuously.
