Maintenance
僅 Store the urea solution tank only in
well-ventilated locations. When urea
solution is exposed to the hot tem-
perature at approximately 50°C for an
extended period of time (i.e. under
direct sunlight), the chemical decom-
position may occur, emitting ammo-
nia vapour.
Storing urea solution (if
equipped)
僅 It is improper to store urea solution in
containers made of unsuitable materi-
als like aluminium, copper alloy, non-
alloyed still and galvanized steel.
The urea solution dissolves metal
materials, severely damaging the
exhaust purification system to be
non-repairable.
僅 Store urea solution only in containers
made of the following materials.
- DIN EN 10 088-1-/-2-/-3-specified
CR-Ni steel, Mo-Cr-Ni steel, Poly-
propylene and Polyethylene
Urea solution purity (if equipped)
僅 The following situations may damage
the DPF system.
- Fuels or any unauthorised liquids
are added into the urea solution
tank.
- Additives are mixed with urea solu-
tion.
- Water is added to dilute the urea
solution.
僅 Use only the ISO 22241- or DIN70070-
specified urea solution. When any
unauthorised urea solution is added
to the urea solution tank, have your
vehicle inspected by a professional
workshop. Kia recommends to contact
an authorised Kia dealer/service part-
ner.

僅 When any unauthorised impurities
enter the urea solution tank, it may
lead to the following problems.
- Increased emission
- Malfunction with the DPF system
- Engine failure
Never add any used urea solution, which
is drained from the urea solution tank
(i.e. whilst maintaining the vehicle). Its
purity cannot be guaranteed. Always
add new urea solution.
Liquid such as diesel, petrol and alcohol
shall never be used for SCR system. Any
Specification of fluid other than recommended urea
the standard solution (conform to ISO22241 or
urea solution DIN70070) can damage SCR system
hardware and deteriorate vehicle emis-
sion.
WARNING
僅 When opening the urea solution tank
cap at high outside temperatures,
ammonia vapours may escape.
Ammonia vapours have a pungent
smell and primarily cause irritation of
the:
- Skin
- Mucous membranes
- Eyes
You may experience a burning sensa-
tion in your eyes, nose and throat, as
well as coughing and watering of the
eyes. Do not inhale ammonia vapours.
Do not allow urea solution to come in
direct contact with your skin. It is haz-
ardous to your health. Wash any
affected areas off with plenty of clean
water. If necessary, consult a doctor.
僅 When handling with urea solution in
closed space, ensure good ventilation.
When the bottle of urea solution con-
tainer is opened, pungent smelling
fumes may escape.
