Introduction
Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol 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 ethanol of any
kind if driveability 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. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.Never use fuel which contains
methanol. Discontinue use of any
petrol product which impairs dri-
vability.
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 catalytic converter, or
abnormal corrosion, 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 problems caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.

Introduction
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.
Your New Vehicle Limited
Warranty may not cover damage
to the fuel system and any per-
formance problems that are
caused by the use of fuels con-
taining methanol or fuels contain-
ing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
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) 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, adding one bottle of addi-
tives to the fuel tank is recommended
according to the maintenance sched-
ule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.

Introduction
Diesel engine
Diesel fuel
Diesel engines 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 dam-
age to the engine and fuel system.
The new vehicle warranty may be
invalidated if non-approved fuels
and/or fuel additives are used.
Diesel fuel of above cetane 51
should be used in your vehicle. If two
types of diesel fuel are available, use
summer or winter fuel properly
according to the following tempera-
ture 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.Do not let any petrol or water enter
the tank. This would make it nec-
essary to drain it out and to bleed
the lines to avoid jamming the
injection pump and damaging the
engine.
It is recommended to use the reg-
ulated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including
high sulfur (more than 50 ppm sul-
fur) 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, 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 manufacturer's warranty.
Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the latest
petroleum industry specifica-
tion.
Never use any fuel additives or
treatments that are not recom-
mended or approved by the
vehicle manufacturer.

Biodiesel (for New Zealand)
Commercially supplied Diesel blends
of no more than 7% biodiesel, com-
monly known as "B7 Diesel" may be
used in your vehicle if the 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), 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 manufacturer's warranty. Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the latest
petroleum industry specifica-
tion.
Never use any fuel additives or
treatments that are not recom-
mended or approved by the
vehicle manufacturer. 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.

Convenient features of your vehicle
If you suspect your smart key might
have sustained some damage, or
you feel your smart key is not work-
ing correctly, it is recommended that
you contact an authorised HYUNDAI
dealer.
Information
An inappropriately disposed
battery can be harmful to the
environment and human health.
Dispose of the battery according
to your local law(s) or regula-
tions.
Immobiliser system
(if equipped)
The immobiliser system protects your
vehicle from theft. If an improperly
coded key (or other device) is used,
the engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobiliser sys-
tem indicator should come on briefly,
then go off. If the indicator starts to
blink, the system does not recognise
the coding of the key.
Place the ignition switch to the
LOCK/OFF position, then place the
ignition switch to the ON position
again.
The system may not recognise your
key’s coding if another immobiliser
key or other metal object (i.e., key
chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognise the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
The transponder in your key is an
important part of the immobiliser
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobiliser sys-
tem malfunction could occur.
NOTICE
iIn order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle.
