Refilling urea solution with a refill bottle

  • Press the ignition switch or ENGINE START/STOP button to the OFF position.

  • Turn the urea solution tank cap in a counterclockwise direction to open it.

  • Add the ISO 22241-specified urea solution. Fill in a sufficient amount of urea solution.

    Pay great caution not to add the urea solution into the fuel tank. If not, it surely applies adverse impact on the vehicle performance, causing various malfunctions.

    Pay great caution not to overfill the (completely) filled urea solution tank by force whilst refilling urea solution from a refill bottle. An over-filled urea solution tank will be expanded when it becomes frozen and this can cause a serious malfunction of the urea solution tank or urea solution system.

    Never use urea solution mixture with additives or water. It may allow foreign substances to enter the urea solution tank. If so, it surely applies adverse impact on the vehicle performance, causing various malfunctions.

    Use only the ISO 22241-specified urea solution. Any unauthorized urea solution surely applies adverse impacts on the vehicle performance, causing various malfunctions.

  • Turn the urea solution tank cap in a clockwise direction to securely close it.

Adding urea solution: Every approximately 5,600 km (The urea solution consumption is dependent on the road profile, driving pattern and environmental condition)

It takes some time to update the cluster gauges after the urea solution injection.

WARNING

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

  • Do not arbitrarily modify or manipulate the DPF system by redirecting or lengthen the exhaust pipe. It may adversely impact the DPF system.

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

  • Any arbitrary manipulation or modification of the DPF system may cause a system malfunction. The DPF system is controlled by a complex electronic control unit.

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

  • Add only the specified urea solution, when your vehicle is equipped with the urea solution system.

  • The urea solution system (i.e. urea solution nozzle, urea solution pump, and DCU) operates for approximately 2 minutes more to eliminate the remaining urea solution inside, even after the ignition switch or ENGINE START/STOP button is pressed to the OFF position. Before the maintenance service, make sure that the urea solution system is completely turned OFF.

  • A urea solution of poor quality or any unauthorized liquids may damage the 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 urea solution comes in contact with the eyes or the skin, you should thoroughly wash the contaminated skin area.

  • When you swallow urea solution, thoroughly rinse your mouth and drink a lot of fresh water. Then, immediately consult a doctor.

  • When your cloth is contaminated with urea solution, immediately change your cloth.

  • When you have an allergic reaction to urea solution, immediately consult a doctor.

  • Make sure that urea solution is kept out of reach from children.

  • Wipe off any urea solution spillage with water or cloth. When urea solution is crystalized, wipe it off with a sponge or a cloth, which was dampened in cold water.

    When urea solution spillage is exposed in air for an extended period of time, it is crystalized in white, damaging the vehicle surface.

  • Urea solution is not a fuel additive. Thus, it should not be injected to the fuel tank. Otherwise, it may damage the engine.

  • Urea solution is an aqueous solution, which is inflammable, non-toxic, colorless and odorless.

  • Store the urea solution tank only in well-ventilated locations. When urea solution is exposed to the hot temperature at approximately 50°C for an extended period of time (i.e. under direct sunlight), the chemical decomposition may occur, emitting ammonia vapor.
