Urea solution purity

  • The following situations may damage the DPF system.

    • Fuels or any unauthorized liquids are added into the urea solution tank.

    • Additives are mixed with urea solution.

    • Water is added to dilute the urea solution.

  • Use only the ISO 22241- or DIN70070-specified urea solution. When any unauthorized urea solution is added to the urea solution tank, have your vehicle inspected by a professional workshop. Kia recommends to contact an authorized Kia dealer/service partner.

  • When any unauthorized 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.

Specification of the standard urea solution

Liquid such as diesel, petrol and alcohol shall never be used for SCR system. Any fluid other than recommended urea solution (conform to ISO22241 or DIN70070) can damage SCR system hardware and deteriorate vehicle emission.
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 the vehicle surface, wash out the surface with clean water to prevent any corrosion.

  • When replenishing, be careful lest the urea solution should overflow.

  • In case the vehicle was parked at very low ambient temperature (below -11 degree Celsius) for a long time, the urea solution will be frozen in the urea solution tank. With frozen urea solution, the urea solution tank level may not be detected correctly until the urea solution will be defrosted by activated heater. Incorrect urea solution or diluted urea solution can increase the freezing point, and thus defrosting may not be properly done by the heater w hich 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 unrecommended liquid is supplied, damage on car parts such as emission reduction devices can be caused. If defective fuel is added, foreign objects will be accumulated to SCR catalyst and cause it to get clogged and break.

    After adding incorrect urea solution, please visit the nearby authorized Kia dealer/ service partner as early as possible.

  • Liquid that are not recommended such as diesel, petrol, and alcohol shall never be used other than the recommended urea solution that satisfy ISO22241 or DIN70070.

  • 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.
