Maintenance
WARNING
• When the urea solution contacts
with the eyes or the skin, you should
thoroughly wash the contaminated
skin area.
• When you swallow the urea solution,
thoroughly rinse your mouth and
drink a lot of fresh water. Then,
immediately consult a doctor.
• When your cloth is contaminated
with the urea solution, immediately
change your cloth.
• When you have an allergic reaction
to the urea solution, immediately
consult a doctor.
• Keep children away from urea
solution.
• 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 urea solution
in closed space, ensure good
ventilation. When the bottle of
urea solution container is opened,
pungent smelling fumes may escape

NOTICE
• Wipe off any urea solution spillage
with water or dampened cloth. When
the urea solution is crystalized, wipe
it off with sponge or cloth, which is
dampened in cold water.
When the urea solution spillage is
exposed in the air for an extended
period of time, it is crystalized in
white, damaging the vehicle surface.
• When urea solution overflows onto
vehicle surface, wash out vehicle
surface with clean water to prohibit
corrosion from occurring.
• Store the urea solution tank only
in well ventilated locations. When
urea solution is exposed to hot
temperature at approximately 50°C
(122°F) for an extended period of
time (for example, under direct
sunlight), chemical decomposition
may occur, emitting ammonia vapor.
• In case the vehicle was parked at
very low ambient temperature
(below 11°C (33°F) 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
melts. Incorrect urea or diluted urea
may increase the freezing point, so
only use specified urea solution.
The time for the urea solution to
melt varies in accordance with
driving conditions and outside
temperatures.
