EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by a
HYUNDAI authorised repairer in accor-
dance with the maintenance schedule in
this manual.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
• To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
• After dynamometer testing is com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative emission control
system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the atmos-
phere.
Canister
Fuel vapours generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapours absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms-
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.

3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions whilst maintaining
good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
• If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorised electronic
devices.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present with
other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.• Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
• When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
• Never sit in a parked or stopped vehi-
cle for any extended time with the
engine running.
• When the engine stalls or fails to start,
excessive attempts to restart the
engine may cause damage to the
emission control system.
WARNING- Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though
colourless and odourless, it is dan-
gerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poisoning.

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 petrol
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 a HYUNDAI autho-
rised repairer.
• Avoid driving with a very low fuel level.
If you run out of petrol, it could cause
the engine to misfire and result in
excessive loading of the catalytic con-
verter.
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 37 mph (60km/h) 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 whilst 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.

Low urea warning message
(if equipped)
The lack warning messages of Urea
appear below Urea 3.7 litre. 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 litres of
urea. When "Refill Urea in 000km or vehi-
cle will not start" message is displayed,
fill up urea at least 4 litres. 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.

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 vapour.(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, colourless and odour-
less.

Urea solution purity
• The following situations may damage
the DPF system.
- Fuels or any unauthorized liquids are
added into the urea solution tank.
- Additives are mixed in the urea solu-
tion.
- Water is added to dilute the urea
solution.
• Use only the ISO 22241- or DIN7007O-
specified urea solution. When any unau-
thorized urea solution is added to the
tank, we recommend 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 main-
taining the vehicle). Its purity cannot be
guaranteed. Always add the new urea
solution.WARNING
• When opening the urea solution
tank cap at high outside tempera-
tures, 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 coughing 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, con-
sult a doctor.
• When handling with urea solution
in closed space, ensure good
ventilation. When the bottle of
urea solution container is
opened, pungent smelling fumes
may escape.

CAUTION
• If defective urea solution or liquid
that is not recommended is sup-
plied, there may be damage on
the parts of the vehicle such as
processing device. If defective
fuel is used, foreign objects will
be accumulated to SCR catalyst
and cause catalyst pushed away
or breaking.
After adding the incorrect urea
solution, please visit the closest
service centre as early as possi-
ble.
• Liquid that are not recommended
such as diesel, petrol, and alcohol
shall never be used other than the
recommended urea solution that
satisfy ISO22241 or DIN70070.
• If defective urea solution or liquid
that is not recommended is sup-
plied, there may be damage on
the parts of the vehicle such as
processing device. If defective
fuel is used, foreign objects will
be accumulated to SCR catalyst
and cause catalyst pushed away
or breaking.
(Continued)
• The time to defrost the urea solu-
tion varies in accordance with
driving conditions and outside
temperatures.(Continued)
• 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 occur-
ring.
• 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 cor-
rectly until the urea solution will
be defrosted by activated heater.
Incorrect urea or diluted urea can
increase the freezing point, and
thus defrosting may not be prop-
erly done by the heater which is
activated below certain tempera-
tures. This phenomenon may
cause malfunction of the SCR
system which can lead to the pro-
hibition of engine restarting.
