Operating precautions for catalyt-
ic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for
petrol engine.
• Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
• 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 con-
trol system. All inspections and
adjustments must be made by a
HYUNDAI authorised 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 converter.Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
WARNING- Fire
• A hot exhaust system can
ignite flammable items under
your vehicle. Do not park,
idle, or drive the vehicle over
or near flammable objects,
such as dry grass, paper,
leaves, etc.
• The exhaust system and cat-
alytic system are very hot
whilst the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.

Diesel Particulate Filter
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot according to the driving condi-
tion. In other words, the active burn-
ing by engine control system and
high exhaust gas temperature
caused by normal/high driving condi-
tion burns and removes the accumu-
lated soot.
However, if the vehicle continues to
be driven at low speed for long time,
the accumulated soot may not be
automatically removed because of
low exhaust gas temperature. In this
particular case, the amount of soot is
out of detection limit, the soot oxida-
tion process by engine control sys-
tem may not happen and the mal-
function 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).
If the malfunction indicator light con-
tinues to be blinked in spite of the
procedure, please visit a HYUNDAI
authorised repairer and then check
the DPF system.
If you continue to drive with the mal-
function 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
regulated 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 addi-
tives, it can cause the DPF sys-
tem to be damaged and white
smoke can be emitted.
