3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while 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 unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge or fire. For your safety,
do not use unauthorized electric
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 color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions following to
avoid CO poisoning.

Maintenance
Operating precautions for catalyticconverters (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 engine.
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. All inspections and adjustments
must be made by an authorized
HYUNDAI dealer.
Avoid driving with a extremely low fuel level. Running out of fuel cause the
engine to misfire, damaging the cat-
alytic 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 emitted from the
vehicle.
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 low speed for long time, the
accumulated soot may not be automati-
cally removed because of low exhaust
gas temperature. In this particular case,
the amount of soot is out of detection
limit, the soot oxidation process by
engine control system may not happen
and the malfunction indicator light may
blink.
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 ~
2000 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 dry grass, 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 sys-
tem 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.

Downloaded from www.Manualslib.com manuals search engine If the malfunction indicator light contin-
ues to be blinked in spite of the proce-
dure, please visit an authorized
HYUNDAI dealer and then 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.
CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu-
lated automotive diesel fuel fordiesel vehicle equipped with theDPF system.
If you use diesel fuel including highsulfur (more than 50 ppm sulfur) and unspecified additives, it cancause the DPF system to be dam-aged and white smoke can be emit-ted.
