To prevent damage to your vehicle:

• Use only specified urea solution. Never add any other urea solution than what has been specified.

• Be careful not to add urea solution into the fuel tank.

• While adding urea, be careful not to allow foreign substances to enter into the urea solution tank.

• Do not mix water or additives with the urea solution.

• Do not over fill the urea solution tank. In cold weather, the tank will expand if the urea freezes.

• Do not apply any external impact on the DPF system. It may damage the catalyst, which is equipped inside the DPF system.

• Do not modify the DPF system by redirecting or lengthening the exhaust pipe. It may adversely effect the DPF system.

• Avoid contact with the drained water from the exhaust pipe. The water is slightly acid and harmful to skin. If contacted, thoroughly wash it off.

• Any modification of the DPF system may cause system malfunction. The DPF system is controlled by a complex device.

• Wait for the DPF system to cool down before maintenance, as it is hot due to heat generation. Otherwise, it may cause skin burn.

• The Selective Catalytic Reduction system (for example, urea solution nozzle, urea solution pump, and DCU) operates for approximately 2 minutes more to eliminate the remaining urea solution inside, even after the engine is turned OFF. Before working on the vehicle, make sure that the Selective Catalytic Reduction system is completely turned OFF.

• Poor urea solution or unauthorized liquids may damage vehicle components, including the DPF system. Any unverified additives in the urea solution may clog the SCR catalyst and cause other malfunctions, which require the expensive DPF system to be replaced.

• 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

• The following situations may damage the DPF system.

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

  • Additives are mixed in the urea solution

  • Water is mixed in the urea solution

• Use only specified urea solution.

  When any unauthorized urea solution is added to the tank, we recommend that you contact an authorized HYUNDAI dealer.

• When any foreign substances enter the urea solution tank, the following problems may occur.

  • Increased emission

  • DPF system malfunction

  • Engine failure

• Never add used urea solution as its quality cannot be guaranteed. Always add new urea solution.

• 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 (12°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.

Urea solution is a water-soluble substance, which is inflammable, non-toxic, colorless and odorless.
