The lack warning messages of Urea
appear below Urea 5.4 liter. When
the warning message "Low Urea" is
displayed with SCR warning lamp
( ), the urea tank needs to be
refilled. If not refilled for a consider-
able mileage, visual warning system
will escalate the intensity by display-
ing the message "Refill Urea" with
SCR warning lamp ( ).
In this case, the tank soon needs to
be refilled. The remaining urea in the
tank approaches to too low level the
warning message "Refill Urea tank
or vehicle will not start" with SCR
warning lamp ( ). "xxx km(mile)"
represents the remaining travel dis-
tance allowed, so do not continue
driving to the limit of the remaining
travel distance without refilling.Otherwise, the vehicle can't be
restarted once the engine is turned
off by ignition key. Based on the driv-
ing pattern, environmental condition
and road profile, the deducted
remaining mileage may differ from
the actual travel distance.
When "Low Urea" or "Refill Urea"
message is displayed, add enough
urea. When "Refill Urea tank or vehi-
cle will not start" message is dis-
played, fill up enough urea. When
"Refill Urea tank or vehicle will not
start" message is displayed with
SCR warning lamp ( ), the vehicle
can't be restarted once the engine is
turned off by ignition key. For the
above cases, full replenishment is
always recommended.

Maintenance

❈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.
Adding the 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
injection.

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

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.
