Fill the upper tank to the correct amount of diesel exhaust fluid, previously specified by the Land Rover approved diagnostic equipment.

CAUTIONS:

• Failure to carry out this instruction may cause damage to the vehicle.
• If any diesel exhaust fluid is visible in the clear filler pipe, this must be drained and discarded before proceeding to the next step.

Make sure that the inner rubber feed hose is in the position shown

CAUTIONS:

• Make sure the diesel exhaust fluid dispensing kit is correctly installed onto the diesel exhaust fluid filler pipe.
• Make sure that the vehicle paintwork is protected.

Install the diesel exhaust fluid dispensing kit on to the diesel exhaust fluid filler pipe.

NOTE:

Fluid may be visible in the outer hose.

Position the diesel exhaust fluid dispensing kit upper operating lever in the position indicated. The diesel exhaust fluid tank top-up procedure will now commence. Immediately proceed to the next step.

CAUTION:

Do not overfill the vehicle.

1. Fill the vehicle with the correct amount of diesel exhaust fluid specified by the Land Rover approved diagnostic equipment.
2. When the correct amount has been drained, position the diesel exhaust fluid dispensing kit upper operating lever to the position indicated.

1. Position the diesel exhaust fluid dispensing kit lower operating lever to the position indicated.
2. Operate the pump on the diesel exhaust fluid dispensing kit to recover any diesel exhaust fluid remaining in the clear filler pipe. The diesel exhaust fluid is recovered through the inner pipe at the vehicle filler pipe. The pipe may need to be raised to assist recovery.

NOTE:

Make sure the pump on the diesel exhaust fluid dispensing kit is switched off before this step is carried out.

Position the diesel exhaust fluid dispensing kit lower operating lever in the position indicated.

Using the Land Rover approved diagnostic equipment, follow the on-screen instructions and check the diesel exhaust fluid level.

CAUTIONS:

• If any fluid remains in the clear filler pipe after the diesel exhaust fluid dispensing kit is disconnected from the vehicle, this must be drained and discarded before the equipment can be used again.
• Make sure that the vehicle paintwork is protected.

Disconnect the diesel exhaust fluid dispensing kit from the diesel exhaust fluid filler pipe.

CAUTION:

Make sure that the mating faces are clean and free of foreign material.
