Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for “European
Norm”). Do not use marine diesel fuel,
heating oils, or non-approved fuel
additives, as this will increase wear and
cause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a
limitation of your warranty rights.
Diesel fuel of above cetane 51 is used
in your vehicle. If two types of diesel
fuel are available, use summer or winter
fuel properly according to the following
temperature conditions.
• Above -5°C (23°F) ... Summer type
diesel fuel.
• Below -5°C (23°F) ... Winter type diesel
fuel.
Watch the fuel level in the tank very
carefully : If the engine stop s through
fuel failure, the circuits must be
completely purged to permit restarting.
CAUTION
Do not let any petrol or water enter the
tank. This would make it necessary to
drain it out and to bleed the lines to
avoid jamming the injection pump and
damaging the engine.
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 additives, it can cause the
DPF system to be damaged and white
smoke can be emitted.
Biodiesel
Commercially supplied Diesel blends of
no more than 7% biodiesel, commonly
known as “B7 Diesel” may be used
in your vehicle if Biodiesel meets EN
14214 or equivalent specifications. (EN
stands for “European Norm”). The use
of biofuels exceeding 7% made from
rapeseed methyl ester (RME), fatty
acid methyl ester (FAME), vegetable oil
methyl ester (VME) etc. or mixing diesel
exceeding 7% with biodiesel will cause
increased wear or damage to the engine
and fuel system. Repair or replacement
of worn or damaged components due to
the use of non approved fuels will not be
covered by the manufactures warranty.
CAUTION
• Never use any fuel, whether diesel,
B7 biodiesel or otherwise, that fails
to meet the latest petroleum industry
specification.
• Never use any fuel additives
or treatments that are not
recommended or approved by the
vehicle manufacturer.

Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system 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 order words, the active burning by
engine control system and high exhaust
gas temperature caused by normal/high
diving condition burns and removes the
accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. More than
a certain amount of soot deposited,
the malfunction indicator light (
)
illuminates.
When the malfunction indicator light
illuminates, it may turn-off after 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).
If the malfunction indicator light (
) is not turn-off or blinking continuesly
in spite of the procedure, visit a
professional workshop and check the
DPF system. HYUNDAI recommends
to visit an authorized HYUNDAI dealer/
service partner.
If you continue to drive with the
malfunction indicator light blinking for
a long time, the DPF system can be
damaged and fuel consumption can be
worsen and the engine durability can be
worsen by oil dilution.
CAUTION
Diesel Fuel (if equipped with DPF)
We recommend you to use only the
regulated diesel fuels, when your
vehicle is equipped with the DPF
system.
When you use other diesel fuels, which
is high in sulfurs (above 50 ppm) or
contains unspecified additives, it may
damage the DPF system and cause the
white smoke emission.
Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in the
exhaust gas depending on the quality
of the fuel and it can degrade NOx
reduction performance, please use the
regulated automotive diesel fuel.
