Hyundai Kona 2019 Owner's Manual - RHD (UK, Australia)

The Gasoline Particulate Filter
(GPF) Lamp stops illuminating, when
the driving speed exceeds 50 mph
(80 km/h) with engine rpm 1,500 ~
4,000 and the gear in the 3rd posi-
tion or above for approximately 30
minutes.
When the GPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates
in the above cases, we recommend
that you have the GPF system
checked by a HYUNDAI authorised
repairer.
When the vehicle is continuously
driven with the GPF Lamp flashing
for an extended period of time, it may
damage the GPF system and lower
the fuel economy.Diesel particulate filter (DPF) (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the
high exhaust-gas temperature at nor-
mal/ high driving speeds.
However, when the vehicle is contin-
ually driven at repeated short dis-
tances or driven at low speed for a
long time, the accumulated soot may
not be automatically removed
because of low exhaust gas temper-
ature. In this case, the accumulated
soot is out of the detection range, the
soot oxidization process does not
occur, and the Diesel Particulate
Filter (DPF) Lamp ( )
Illuminates.

Maintenance
Gasoline (Petrol) Fuel
(if equipped with GPF)
We recommend you to use only
the regulated petrol fuels, when
your vehicle is equipped with
the GPF system.
When you use other petrol fuels
which contain unspecified addi-
tives, they may damage the GPF
system and cause exhaust
emission problems.
CAUTION

The Diesel Particulate Filter (DPF)
Lamp stops illuminating, when the
driving speed exceeds 37mph (60
km/h), or when the engine rpm is
between 1,500 and 2,500 with the
gear in the 2nd position or above for
approximately 25 minutes.
When the DPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates
in the above cases, we recommend
that you have the DPF system
checked by a HYUNDAI authorised
repairer.
When the vehicle is continuously
driven with the DPF Lamp flashing
for an extended period of time, it may
damage the DPF system and lower
the fuel economy.Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide from the
exhaust gas. A smell can occur in the
exhaust gas depending on the quali-
ty of the fuel, and it can degrade NOx
reduction performance. Please use
the regulated automotive diesel fuel.

Maintenance
Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel
fuels, which are high in sulfurs
(above 50 ppm) or that contain
unspecified additives, they may
damage the DPF system and
cause white smoke emissions.
CAUTION

Selective Catalytic Reduction
(if equipped)
The Selective Catalytic Reduction
(SCR) system is to catalytically con-
vert NOx to Nitrogen and Water by
using the reduction agent, the urea
solution.
Urea gauge (if equipped)
The urea solution gauge indicates
the approximate amount of remain-
ing urea solution inside the urea
solution tank.
❈The urea gauge image pops up,
whenever the ignition switch is
pressed to the ON position.

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.

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.

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

7-92
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.
