Operating precautions for catalytic
converters (if equipped)Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for gaso-
line engines.
• Do not operate the vehicle when there
are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
• Do not misuse or abuse the engine.
Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.
• Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
• Do not modify or tamper with any part
of the engine or emission control sys-
tem. We recommend that the system
be inspected by an authorized
HYUNDAI dealer.
• Avoid driving with a very low fuel level.
If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF) sys-
tem removes the soot in the exhaust gas.
Unlike a disposable air filter, the DPF
system automatically burns (oxidizes)
and removes the accumulated soot
according to the driving condition. In
other words, the active burning by engine
control system and high exhaust gas
temperature caused by normal/high driv-
ing condition burns and removes the
accumulated soot.
However, if the vehicle continues to be
driven at repeated short distance or driv-
en at low speed for a long time, the accu-
mulate soot may not be automatically
removed because of low exhaust gas
temperature. More than a certain amount
of soot deposited, the malfunction indica-
tor light ( ) illuminates.
When the malfunction indicator light
blinks, it may stop blinking by driving the
vehicle at more than 60km/h (37 mph) or
at more than second gear with 1500 ~
2500 engine rpm for a certain time (for
about 25 minutes).
WARNING- Fire
• A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegeta-
tion, paper, leaves, etc.
• The exhaust system and catalytic
system are very hot while the
engine is running or immediately
after the engine is turned off. Keep
away from the exhaust system
and catalytic, you may get burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.

Maintenance
If the malfunction indicator light ( )
continues to be blinked or the warning
massage "check exhaust system" illumi-
nates in spite of the procedure, please
visit an authorized HYUNDAI dealer and
the check the DPF system.
If you continue to drive with the malfunc-
tion indicator light blinking for a long
time, the DPF system can be damaged
and fuel consumption can be worsen.Selective Catalytic Reduction
(if equipped)
The Selective Catalytic Reduction (SCR)
system is to catalytically convert NOx to
Nitrogen and Water by using the reduc-
tion agent, the urea solution.
Urea gauge (if equipped)
The urea solution gauge indicates the
approximate amount of remaining urea
solution inside the urea solution tank.
❈The urea gauge image pops up, when-
ever the ignition switch is pressed to
the ON position.
CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu-
lated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur) and
unspecified additives, it can cause
the DPF system to be damaged and
white smoke can be emitted.

Low urea warning message
(if equipped)The lack warning messages of Urea
appear below Urea 3.7 liter. When the
warning message "Low Urea" is dis-
played with SCR warning lamp ( ), the
urea tank needs to be refilled. If not
refilled for a considerable mileage, visual
warning system will escalate the intensi-
ty by displaying 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 in 000km or vehicle
will not start" with SCR warning lamp
( ). "xxx km(mile)" represents the
remaining travel distance allowed, so do
not continue driving to the limit of the
remaining travel distance without refill-
ing.
Otherwise, the vehicle can't be restarted
once the engine is turned off by ignition
key. Based on the driving pattern, envi-
ronmental condition and road profile, the
deducted remaining mileage may differ
from the actual travel distance.When "Low Urea" or "Refill Urea" mes-
sage is displayed, add at least 2 liters of
urea. When "Refill Urea in 000km or vehi-
cle will not start" message is displayed,
fill up urea at least 4 liters. When "Refill
Urea tank or vehicle will not start" mes-
sage 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.

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 mal-
functions have been rectified. If the vehi-
cle can't be restarted with "Refill Urea
tank or vehicle will not start " message,
refill more than 4 liters urea, wait for min-
utes and try vehicle starting again. If
vehicle starting is not possible regardless
of urea level, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.

(Continued)
• The urea solution system (i.e.
urea solution nozzle, urea solu-
tion 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 com-
pletely turned OFF.
• The poor urea solution or the
unauthorized liquids may dam-
age the vehicle components,
including the DPF system. Any
unverified additives in the urea
solution may clog the SCR cata-
lyst and cause other malfunc-
tions, which require the expen-
sive DPF system to be replaced.
• When the urea solution contacts
with the eyes or the skin, you
should thoroughly wash the con-
taminated skin area. .
• When you swallow the urea solu-
tion, thoroughly rinse your mouth
and drink a lot of fresh water. Then,
immediately consult a doctor.
(Continued)WARNING
• Do not apply any external impact
on the DPF system. It may dam-
age 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 system
may cause a system malfunction.
The DPF system is controlled by
the complex device.
• Wait for the DPF system to cool
down before the maintenance
service, as it is hot due to the
heat generation. Otherwise, it
may case a skin burn.
• Add only the specified urea solu-
tion, when your vehicle is
equipped with the urea solution
system.
(Continued)
(Continued)
• When your cloth is contaminated
with the urea solution, immedi-
ately change your cloth.
• When you have an allergic reac-
tion to the urea solution, immedi-
ately 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 solu-
tion 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 damage the
engine.
• The urea solution is the aqueous
solution, which is inflammable,
non-toxic, colorless and odor-
less.

Maintenance
Storing the urea solution
• It is improper to store the urea solution
in the containers made with the certain
materials (i.e. aluminum, copper, cop-
per alloy, non-alloyed still, and galva-
nized steel). The urea solution dis-
solves the metal materials, severely
damaging the exhaust purification sys-
tem to be non-repairable.
• Store the urea solution only in the con-
tainers made with the following materi-
als.
(DIN EN 10 088-1-/-2-/-3-specified CR-
Ni steel, Mo-Cr-Ni steel, polypropy-
lene, and polyethylene)(Continued)
• Store the urea solution tank only
in the well-ventilated locations.
When the urea solution is
exposed to the hot temperature at
approximately 50°C for an extend-
ed period of time (i.e. under the
direct sunlight), the chemical
decomposition may occur, emit-
ting the ammonia vapor.
