Maintenance
Storing the urea solution
• It is improper to store the urea
solution in the containers made
with the certain materials (i.e. alu-
minum, copper, copper alloy, non-
alloyed still, and galvanized steel).
The urea solution dissolves the
metal materials, severely damag-
ing 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,
polypropylene, and polyethylene)
Urea solution purity
• The following situations may dam-
age the DPF system.
- Fuels or any unauthorised liquids
are added into the urea solution
tank.
- Additives are mixed in the urea
solution.
- Water is added to dilute the urea
solution.
• Use only the ISO 22241- or
DIN70070-specified urea solution.
When any unauthorised urea solu-
tion is added to the urea solution
tank, have your vehicle inspected
by a professional workshop. Kia
recommends to contact an autho-
rised Kia dealer/service partner.
• When any unauthorised impurities
enter the urea solution tank, it may
occur the following problems.
- Increased emission
- Malfunction with the DPF system
- Engine failure
Never add the used urea solution,
which is drained from the urea solution
tank (i.e. whilst maintaining the vehi-
cle). Its purity cannot be guaranteed.
Always add the new urea solution.
