Introduction
NOTICE indicates a situation
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.NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorised HYUNDAI dealer for
details.)
NOTICE

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.

Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the service station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the service station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other fuel
source, with your bare hand.
(Continued)
WARNING
(Continued)
When refuelling, always move
the shift lever to the P (Park)
position (for automatic trans-
mission/
dual clutch transmis-
sion) or first gear or R
(Reverse, for manual transmis-
sion), set the parking brake,
and place the ignition switch
to the LOCK/OFF position.
Sparks produced by electrical
components related to the
engine can ignite fuel
vapours
causing a fire.
When using an approved
portable fuel container, be
sure to place the container on
the ground prior to refuelling.
Static electricity discharge
from the container can ignite
fuel vapours causing a fire.
Once refuelling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
(Continued)
(Continued)
Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapours causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other fuel source,
with your bare hand.

according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.
NOTICE
i(Continued)
Use only approved portable
plastic fuel containers designed
to carry and store petrol.
Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle whilst at a service sta-
tion, especially during refu-
elling.
Do not over-fill or top-off your
vehicle tank, which can cause
petrol spillage.
If a fire breaks out during refu-
elling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the service
station and then contact the
local fire department. Follow
any safety instructions they
provide.
