4.
Open up cover (2) at the right side of the machine, clean
blue DEF tank filler cap (3) and surrounding area.
Turn the cap (3) counterclockwise.
The caps of DEF tanks are blue, as required by emission
regulations.
5.
By sight gauge (4), add DEF through the filler port until
float (5) reaches line F (6).
Refill capacity of DEF tank: 23.1 ℓ
Line (7) in the sight gauge indicates approximately 5 ℓ be-
low line F, and line (8) indicates approximately 10 ℓ.
Line (9) is the max adding line when DEF may freeze in
cold weather.
6.
After adding, align claw (10) of the cap with groove (11) of
the filler port and close the cap securely by turning it clock-
wise by 90 °.
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.
