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.
