Malfunction with the SCR system (if equipped)
SCR system has malfunction due to disconnected electrical components, incorrect urea and so on.
"xxx km(mile)" represents the remaining travel distance allowed, so do not continue driving to the limit of the remain-
ing travel distance without fixing the source of the malfunction. Otherwise, the vehicle can't be restarted once the
engine is turned off by ignition key. In this case, we recommend that the system be inspected by a HYUNDAI autho-
rised repairer.

Once the inducement system
reached to final status and disabled
the vehicle restart, it will only be
deactivated in case the urea tank is
replenished or the malfunctions have
been rectified. If the vehicle can't be
restarted with "Refill Urea tank or
vehicle will not start" message, refill
enough urea, wait for minutes and try
vehicle starting again. If vehicle start-
ing is not possible regardless of urea
level, we recommend that the system
be inspected by a HYUNDAI autho-
rised repairer.

Adding the urea solution
To refill the urea solution from the
refill hose
1. Press the ignition switch to theOFF position.
2. Turn the urea solution tank cap in a counterclockwise direction to
open it.
3. Fully insert the refill hose to fully add the ISO 22241-specified urea
solution or above the mark on the
urea solution tank. ❈
Pay the 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.
❈ Never use the urea solution mix-
ture 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 perform-
ance, causing various malfunc-
tions.
❈ Use only the ISO 22241-speci-
fied urea solution. Any unautho-
rized urea solution surely
applies adverse impacts on the
vehicle performance, causing
various malfunctions.
4. Turn the urea solution tank cap in a clockwise direction to securely
close it.
To refill the urea solution from the
refill bottle

2. Turn the urea solution tank cap in a counterclockwise direction to

❈ Pay the 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 the great caution not to
over-fill the (completely) fulfilled
urea solution tank by force whilst
refilling the urea solution from
the refill bottle. The over-filled
urea solution tank will be
expanded when it becomes
frozen and this can cause a seri-
ous malfunction of the urea solu-
tion tank or urea solution sys-
tem.

Maintenance
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 the
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 sys-
tem may cause a system mal-
function. The DPF system is
controlled by the complex
device.
Wait for the DPF system to
cool down before the mainte-
nance service, as it is hot due
to the heat generation.
Otherwise, it may case a skin
burn.
Add only the specified urea
solution, when your vehicle is
equipped with the urea solu-
tion 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 is pressed to the OFF
position. Before the mainte-
nance service, make sure that
the urea solution system is
completely turned OFF.WARNING

Maintenance The poor urea solution or the
unauthorized liquids may
damage the vehicle compo-
nents, including the DPF sys-
tem. 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 con-
tacts 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 contami-
nated with the urea solution,
immediately change your
cloth.
When you have an allergic
reaction to the urea solution,
immediately consult a doctor.
Do not allow a child to contact
the urea solution.
Wipe off any urea solution
spillage with water or cloth.
When the urea solution is
crystalized, wipe it off with the
sponge or the cloth, which is
dampened in the 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.
The urea solution is not the
fuel additives. Thus, it should
not be injected to the fuel
tank. Otherwise, it may dam-
age the engine.The urea solution is the aque-
ous solution, which is inflam-
mable, non-toxic, colourless
and odourless.
Store the urea solution tank
only in the well-ventilated
locations. When the urea solu-
tion is exposed to the hot tem-
perature at approximately
50°C for an extended period of
time (i.e. under the direct sun-
light), the chemical decompo-
sition may occur, emitting the
ammonia vapour.

Storing the urea solution
It is improper to store the ureasolution 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 unauthorized liquidsare 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 DIN7007O-specified urea solution.
When any unauthorized urea solu-
tion is added to the tank, we rec-
ommend you to contact a
HYUNDAI authorised repairer.
When any unauthorized 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 tank (i.e.
whilst maintaining the vehicle). Its
purity cannot be guaranteed. Always
add the new urea solution.

Maintenance
Specification of the tandard urea solution
Liquid such as diesel, gasoline and
alcohol shall never be used for
SCR system. Any fluid other than
recommended urea solution (con-
form to ISO22241 or DIN70070)
can damage SCR system hard-
ware and deteriorate vehicle emis-
sion.

MaintenanceWhen handling with urea
solution in closed space,
ensure good ventilation.
When the bottle of urea solu-
tion container is opened, pun-
gent smelling fumes may
escape.
Keep urea solution out of
reach of children.
When urea solution overflows
into vehicle surface, wash out
vehicle surface with clean
water to prohibit corrosion
from occurring.
When replenishing, be careful
lest the urea solution should
overflow.
In case the vehicle was
parked at very low ambient
temperature (below 11 dgree
Celcius) 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 will be
defrosted by activated heater.
The time to defrost the urea
solution varies in accordance
with driving conditions and
outside temperatures.
When opening the urea solu-
tion 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
sensation in your eyes, nose
and throat, as well as cough-
ing 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
hazardous to your health.
Wash any affected areas off
with plenty of clean water. If
necessary, consult a doctor.
