3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
precautions
• Carbon monoxide can be present
with other exhaust fumes. If you smell
exhaust fumes of any kind in your
vehicle, drive with all the windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the
interior furnishings in a vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm. •
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
vehicle 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.
Operating precautions for catalytic
converters (if equipped)
WARNING
The exhaust system and catalytic
converter are very hot during and
immediately after the engine has been
running. To avoid SERIOUS INJURY or
DEATH:
• Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc. A hot exhaust system can ignite
flammable items under your vehicle.
• Keep away from the exhaust system
and catalytic converter or you may
get burned.
Also, do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle, and
do not coat the vehicle for corrosion
control. It may present a fire risk
under certain conditions.

Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:
• Use only UNLEADED FUEL for
gasoline engines.
• Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
• Do not misuse or abuse the engine.
Examples of misuse are coasting with
the engine off and descending steep
grades in gear with the engine 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
system. We recommend that all
inspections and adjustments are
made by an authorized HYUNDAI
dealer.
• Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.Gasoline Particulate Filter (GPF)
(if equipped)
Gasoline Particulate Filter (GPF) system
removes the soot in the exhaust gas.
The GPF 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 normal/ high driving
speeds. However, when the vehicle is
continually driven at repeated short
distances or driven at low speed for a
long time, the accumulated soot may
not be automatically removed because
of low exhaust gas temperature. In this
case, the accumulated soot may reach
a certain amount regardless of the soot
oxidization process, then the GPF lamp
(
) will illuminate.
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 position or above for
approximately 30 minutes.
When the GPF lamp starts to blink or
the warning message “Check exhaust
system” pops up even though the
vehicle was driven as mentioned above,
we recommend that you have the
GPF system checked by an authorized
HYUNDAI dealer.
With GPF lamp blinking for an extended
period of time, it may damage the GPF
system and lower the fuel economy.
CAUTION
We recommend you to use only the
regulated gasoline fuels, when your
vehicle is equipped with the GPF
system.
When you use other gasoline fuels
which contain unspecified additives,
they may damage the GPF system and
cause exhaust emission problems.
