Petrol containing alcohol andmethanol
Gasohol, a mixture of petrol and
ethanol (also known as grain alco-
hol), and petrol or gasohol containing
methanol (also known as wood alco-
hol) are being marketed along with or
instead of leaded or unleaded petrol.
Do not use gasohol containing more
than 10% ethanol, and do not use
petrol or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer's warranty if they result
from the use of:
1. Gasohol containing more than
10% ethanol.
2. Petrol or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
Other fuels
Using fuel additives such as:
- Silicone fuel additive
- MMT (Magnanese, Mn) fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
NOTICE
F7
Introduction
Never use fuel which contains
methanol. Discontinue use of
any petrol product which
impairs drivability.
CAUTION

Use of MTBE
HYUNDAI recommends avoiding
fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight) in
your vehicle.
Fuel containing MTBE over 15.0%
vol. (Oxygen Content 2.7% weight)
may reduce vehicle performance and
produce vapour lock or hard starting.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.
Fuel Additives
HYUNDAI recommends that you use
unleaded petrol which has an octane
rating of RON (Research Octane
Number) 95 / AKI (Anti Knock Index)
91 or higher.
For customers who do not use good
quality petrols including fuel addi-
tives regularly, and have problems
starting or the engine does not run
smoothly, one bottle of additive
added to the fuel tank according to
the maintenance schedule is recom-
mended. Additives are available from
your HYUNDAI authorised repairer
along with information on how to use
them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regardingregistration and insurance.
Determine that acceptable fuel is available.

Introduction
Your New Vehicle Limited
Warranty may not cover dam-
age to the fuel system and any
performance problems that are
caused by the use of fuels con-
taining methanol or fuels con-
taining MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)
CAUTION

Diesel engine
Diesel fuel
Diesel engine must be operated only
on commercially available diesel fuel
that complies with EN 590 or compa-
rable 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 dam-
age to the engine and fuel system.
The use of non-approved fuels and /
or fuel additives will result in a limita-
tion 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 typediesel fuel.
Below -5°C (23°F) ... Winter type diesel fuel.
Watch the fuel level in the tank very
carefully : If the engine stops through
fuel failure, the circuits must be com-
pletely purged to permit restarting.
Biodiesel
Commercially supplied Diesel blends
of no more than 7% biodiesel, com-
monly 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), veg-
etable oil methyl ester (VME) etc. or
mixing diesel exceeding 7% with
biodiesel will cause increased wear or
damage to the engine and fuel sys-
tem. Repair or replacement of worn or
damaged components due to the use
of non approved fuels will not be cov-
ered by the manufactures warranty.

Introduction
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 jam-
ming the injection pump and
damaging the engine.
CAUTION
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.
CAUTION
Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the lat-
est petroleum industry speci-
fication.
Never use any fuel additives
or treatments that are not rec-
ommended or approved by
the vehicle manufacturer.
CAUTION

The Diesel Particulate Filter (DPF)
Lamp stops illuminating, when the
driving speed exceeds 37mph (60
km/h), or when the engine rpm is
between 1,500 and 2,500 with the
gear in the 2nd position or above for
approximately 25 minutes.
When the DPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates
in the above cases, we recommend
that you have the DPF system
checked by a HYUNDAI authorised
repairer.
When the vehicle is continuously
driven with the DPF Lamp flashing
for an extended period of time, it may
damage the DPF system and lower
the fuel economy.Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide from the
exhaust gas. A smell can occur in the
exhaust gas depending on the quali-
ty of the fuel, and it can degrade NOx
reduction performance. Please use
the regulated automotive diesel fuel.

Maintenance
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 are high in sulfurs
(above 50 ppm) or that contain
unspecified additives, they may
damage the DPF system and
cause white smoke emissions.

urea solution tank. ❈
Pay the great caution not to add
the urea solution into the fuel
tank. If not, it surely applies
adverse impact on the vehicle
performance, causing various
malfunctions.
❈ Never use the urea solution mix-
ture with additives or water. It
may allow foreign substances to
enter the urea solution tank. If
so, it surely applies adverse
impact on the vehicle perform-
ance, causing various malfunc-
tions.
❈ Use only the ISO 22241-speci-
fied urea solution. Any unautho-
rized urea solution surely

Maintenance The poor urea solution or the
unauthorized liquids may
damage the vehicle compo-
nents, including the DPF sys-
tem. Any unverified additives
in the urea solution may clog
the SCR catalyst and cause
other malfunctions, which
require the expensive DPF
system to be replaced.
When the urea solution con-
tacts with the eyes or the skin,
you should thoroughly wash
the contaminated skin area. .
When you swallow the urea
solution, thoroughly rinse
your mouth and drink a lot of
fresh water. Then, immediately
consult a doctor.
When your cloth is contami-
nated with the urea solution,
immediately change your
cloth.
When you have an allergic
reaction to the urea solution,
immediately consult a doctor.
Do not allow a child to contact
the urea solution.
Wipe off any urea solution
spillage with water or cloth.
When the urea solution is
crystalized, wipe it off with the
sponge or the cloth, which is
dampened in the cold water.
When the urea solution
spillage is exposed in the air
for an extended period of
time, it is crystalized in white,
damaging the vehicle surface.
The urea solution is not the
fuel additives. Thus, it should
not be injected to the fuel
tank. Otherwise, it may dam-
age the engine.The urea solution is the aque-
ous solution, which is inflam-
mable, non-toxic, colourless
and odourless.
Store the urea solution tank
only in the well-ventilated
locations. When the urea solu-
tion is exposed to the hot tem-
perature at approximately
50°C for an extended period of
time (i.e. under the direct sun-
light), the chemical decompo-
sition may occur, emitting the
ammonia vapour.

Storing the urea solution
It is improper to store the ureasolution in the containers made
with the certain materials (i.e. alu-
minum, copper, copper alloy, non-
alloyed still, and galvanized steel).
The urea solution dissolves the
metal materials, severely damag-
ing the exhaust purification system
to be non-repairable.
Store the urea solution only in the containers made with the following
materials.
(DIN EN 10 088-1-/-2-/-3-specified
CR-Ni steel, Mo-Cr-Ni steel,
polypropylene, and polyethylene)
Urea solution purity
The following situations may dam-age the DPF system.
- Fuels or any unauthorized liquidsare added into the urea solution
tank.
- Additives are mixed in the urea solution.
- Water is added to dilute the urea solution.
Use only the ISO 22241- or DIN7007O-specified urea solution.
When any unauthorized urea solu-
tion is added to the tank, we rec-
ommend you to contact a
HYUNDAI authorised repairer.
When any unauthorized impurities enter the urea solution tank, it may
occur the following problems.
- Increased emission
- Malfunction with the DPF system
- Engine failure
Never add the used urea solution,
which is drained from the tank (i.e.
whilst maintaining the vehicle). Its
purity cannot be guaranteed. Always
add the new urea solution.
