OPERATION
REMARK
• It is recommended to use a nozzle having a diameter and a length specified by ISO 22241-4 and an auto
stop function to add DEF. When the specified nozzle is used, the magnet installed inside the filler port of the
tank cancels the wrong fluid addition prevention device, and you can add DEF. This mechanism prevents
addition of DEF into the fuel tank, addition of fuel into DEF tank, and spill of DEF from the filler port.
• When using a nozzle which is not conformed to ISO 22241-4, hold it in your hand and add DEF carefully
while checking the sight gauge.
• Add only DEF in clearly marked DEF tanks that have the blue cap.
