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.)

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.

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

Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas. Unlike a disposable air
filter, the DPF system automatically
burns (oxidizes) and removes the
accumulated soot according to the
driving condition. In order words, the
active burning by the engine control
system and high exhaust gas tem-
perature caused by normal/high
speed diving condition burns and
removes the accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of
low exhaust gas temperature. If more
than a certain amount of soot
deposited, the malfunction indicator
light( ) illuminates.
When the malfunction indicator light
illuminates, it may turn-off after driv-
ing the vehicle at more than 60km/h
(37 mph) or at more than second
gear with 1500~2500 engine rpm for
a certain time (for about 25 minutes).If the malfunction indicator light ( )
continues to blink or the warning mes-
sage “Check exhaust system” illumi-
nates in spite of the procedure, visit a
professional workshop and check the
DPF system. HUNDAI recommends to
visit an authorised HYUNDAI dealer.
If you continue to drive with the mal-
function indicator light blinking for a
long time, the DPF system can be
damaged and fuel consumption can
be worsen and the engine durability
can be worsen by oil dilution.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 is high in sulfurs (above
50 ppm) or contains unspecified
additives, it may damage the
DPF system and cause the white
smoke emission.
