Your Hyundai should not be modified in any way without the approval of Hyundai. Any mod-
ifications may adversely affect the safety, durability and performance of your Hyundai. In
addition, those components which are subjected to modification or are added to the vehicle
specification, and any resultant consequential damage will not be covered by the vehicle
manufacturer's warranty.
Your vehicle is equipped with electronic fuel injection and other electronic components.
It is possible for an improperly installed/adjusted two-way radio or mobile phone to adversely
affect electronic systems. For this reason, we recommend that you carefully follow the radio
manufacturer's instructions or consult your Hyundai dealer for precautionary measures or
special instructions.

which, if not avoided, could result
in vehicle damage.
Petrol engine
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. Do not use
methanol blended fuels.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.

•Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
NEVER USE LEADED FUEL.
The use of leaded fuel is detri-
mental to the catalytic converter
and will damage the engine
control system’s oxygen sensor
and affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been spec-
ified (We recommend that you
consult an authorised HYUNDAI
dealer for details.)
CAUTION

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.
Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained
fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained
fuels,
may cause vehicle and engine dam-
age or cause plugging, misfiring,
poor acceleration, engine stalling,
catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
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

Introduction
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.
CAUTION

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.
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
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 recommend-
ed according to the maintenance
schedule (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.
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 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. 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

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 manufacturer’s warranty. 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
It is recommended to use the
regulated automotive diesel
fuel for diesel vehicles
equipped with the DPF system.
If you use diesel fuel including
high sulphur (more than 50 ppm
sulphur) 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

Introduction
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 manufactures war-
ranty.No special run-in period is needed.
By following a few simple precau-
tions for the first 1,000 km you may
add to the performance, economy
and life of your vehicle.
Do not race the engine.
Whilst driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is
needed to properly run-in the
engine.
Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
properly.
Don't tow a trailer during the first
2,000 km of operation. 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
