• The urea solution system (i.e. urea
solution nozzle, urea
pump, and DCU) operates for ap‐
proximately 2 minutes more to
eliminate the remaining urea solu‐
tion inside, even after the engine
start/stop button is pressed to the
OFF position. Before the mainte‐
nance service, make sure that the
urea solution system is completely
turned OFF.
• The poor urea solution or the un‐
authorised liquids may damage
the vehicle components, including
the DPF system. Any unverified
additives in the urea solution may
clog the SCR catalyst and cause
other malfunctions, which require
the expensive DPF system to be
replaced.
• When the urea solution contacts
with the eyes or the skin, you
should thoroughly wash the conta‐
minated skin area.

• When you swallow the urea solu‐
solution tion, thoroughly rinse your mouth
and drink a lot of fresh wa‐
ter.Then, immediately consult a
doctor.
• When your cloth is contaminated
with the urea solution, immediate‐
ly change your cloth.
• When you have an allergic reaction
to the urea solution, immediately
consult a doctor.
• Do not allow a child to contact the
urea solution.
• Wipe off any urea solution spillage
with water or cloth. When the urea
solution is crystalized, wipe it off
with the sponge or the cloth,
which is dampened in the cold wa‐
ter. When the urea solution spill‐
age is exposed in the air for an ex‐
tended period of time, it is crystal‐
ized in white, damaging the vehicle
surface.
• The urea solution is not the fuel
additives. Thus, it should not be in‐
jected to the fuel tank. Otherwise,
it may damage the engine.

• The urea solution is the aqueous
solution, which is inflammable,
non-toxic, colourless and odour‐
less.
• Store the urea solution tank only
in the well-ventilated locations.
When the urea solution is exposed
to the hot temperature at approxi‐
mately 50°C for an extended peri‐
od of time (i.e. under the direct
sunlight), the chemical decomposi‐
tion may occur, emitting the am‐
monia vapour.
Storing the urea solution
• It is improper to store the urea solu‐
tion in the containers made with the
certain materials (i.e. aluminum, cop‐
per, copper alloy, nonalloyed still, and
galvanized steel). The urea solution
dissolves the metal materials, severe‐
ly damaging the exhaust purification
system to be non-repairable.
• Store the urea solution only in the
containers made with the following
materials.
(DIN EN 10 088-1-/-2-/-3-specified
CR-Ni steel, Mo-Cr-Ni steel, polypro‐
pylene, and polyethylene)
