F8
Introduction
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.
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.
NOTICE
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.)
CAUTIONNever use gasohol which con-
tains methanol. Discontinue
use of any gasohol product
which impairs drivability.
CAUTION

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
We recommend to use unleaded
petrol which has an octane rating of
RON (Research Octane Number) 91
/ AKI (Anti Knock Index) 87 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 regarding
registration and insurance.
• Determine that acceptable fuel is
available.
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 type
diesel 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.

Introduction

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 spec-
ifications. (EN stands for "European
Norm"). The use of biofuels exceed-
ing 7% made from rapeseed methyl
ester (RME), fatty acid methyl ester
(FAME), vegetable oil methyl ester
(VME) etc. or mixing diesel exceed-
ing 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.• This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
• If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.

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
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.
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.

Maintenance
The Gasoline (Petrol) Particulate
Filter (GPF) Lamp stops illuminating,
when the driving speed exceeds 50
mph (80 km/h), or when the engine
rpm is between 1,500 and 4,000 with
the gear in the 3rd position or above
for approximately 30 minutes.
When the GPF Lamp continuously
blinks or the warning message “Check
exhaust system” illuminates in the
above cases, we recommend that you
have the GPF system checked by a
HYUNDAI authorised repairer.
When the vehicle is continuously driv-
en with the GPF Lamp flashing for an
extended period of time, it may dam-
age the GPF system and lower the
fuel economy.
Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF system automatically burns
(or oxidises) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.However, when the vehicle is continu-
ally driven at repeated short distances
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot is out of the
detection range, the soot oxidization
process does not occur, and the
Diesel Particulate Filter (DPF) Lamp
( ) Illuminates.
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 unspeci-
fied additives, they may damage
the DPF system and cause white
smoke emissions.
CAUTION
Gasoline (Petrol) Fuel
(if equipped with GPF)
We recommend you to use only
the regulated petrol fuels, when
your vehicle is equipped with
the GPF system.
When you use other petrol fuels
which contain unspecified addi-
tives, they may damage the GPF
system and cause exhaust
emission problems.

mark on the urea solution tank.
❈When "Refill Urea tank or vehicle
will not start" message is dis-
played, fill up urea at least 6 litres.❈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-
rised urea solution surely
applies adverse impacts on the
vehicle performance, causing
various malfunctions.
4. Turn the urea solution tank cap in
a clockwise direction to securely

Maintenance
•The poor urea solution or the
unauthorised 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 crystalised 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.

Maintenance
Storing the urea solution
• It is improper to store the urea
solution in the containers made
with the certain materials (i.e. alu-
minium, 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 unauthorised liquids
are 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 unauthorised urea solu-
tion is added to the tank, we rec-
ommend you to contact a
HYUNDAI authorised repairer.
• When any unauthorised 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.
Specification of the
tandard urea solution
Liquid such as diesel, petrol and
alcohol shall never be used for
SCR system. Any fluid other than
recommended urea solution (con-
form to ISO22241 or DIN70070)
can damage SCR system hard-
ware and deteriorate vehicle emis-
sion.
