WARNING
• When opening the urea solution tank
cap at high outside temperatures,
ammonia vapors may escape.
Ammonia vapors have a pungent
smell and primarily cause irritation
of the:
- Skin
- Mucous membranes
- Eyes
You may experience a burning
sensation in your eyes, nose and
throat, as well as coughing and
watering of the eyes. Do not inhale
ammonia vapors. Do not allow urea
solution to come in direct contact
with your skin. It is hazardous to
your health. Wash any affected areas
off with plenty of clean water. If
necessary, consult a doctor.
• When handling with urea solution
in closed space, ensure good
ventilation. When the bottle of
urea solution container is opened,
pungent smelling fumes may escape.
• Keep urea solution out of reach of
children.
• When urea solution overflows into
vehicle surface, wash out vehicle
surface with clean water to prohibit
corrosion from occurring.
When replenishing, be careful lest
the urea solution should overflow.
• In case the vehicle was parked at
very low ambient temperature
(below 11 dgree Celcius) for a long
time, the urea solution will be
frozen in the urea solution tank.
With frozen urea, the tank level may
not be detected correctly until the
urea solution will be defrosted by
activated heater.
Incorrect urea or diluted urea can
increase the freezing point, and thus
defrosting may not be properly done
by the heater which is activated
below certain temperatures. This
phenomenon may cause malfunction
of the SCR system which can lead to
the prohibition of engine restarting.
• The time to defrost the urea
solution varies in accordance with
driving conditions and outside
temperatures.
CAUTION
• If defective urea solution or liquid
that is not recommended is supplied,
there may be damage on the parts
of the vehicle such as processing
device. If defective fuel is used,
foreign objects will be accumulated
to SCR catalyst and cause catalyst
pushed away or breaking.
After adding the incorrect urea
solution, please visit the closest
service center as early as possible.
• Liquid that are not recommended
such as diesel, gasoline, and alcohol
shall never be used other than the
recommended urea solution that
satisfy ISO22241 or DIN70070.
