5.
Open the cover (2) on the right side of the machine, and
clean the DEF tank cap and the area around.

Turn the cap of filler port (3) counterclockwise.
The cap of filler port is opened.
7.
By sight gauge (4), add DEF through the filler port until
float (5) reaches the line F (6).
Line (7) in the sight gauge indicates approximately 5 ℓ be-
low the line F, and the line (8) indicates approximately 10 ℓ
below the line F.
Line (9) is the upper limit line for adding when DEF may
freeze in cold weather.

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.
