Introduction
Petrol engine
Unleaded
For the optimal vehicle performance,
we recommend you to use unleaded
petrol which has an EN 228 and has
an octane rating of RON (Research
Octane Number) 95 / AKI (Anti
Knock Index) 91 or higher.(Do not
use methanol blended fuels.)
You may use unleaded petrol with an
octane rating of RON 91-94 / AKI 87-
90 but it may result in slight perform-
ance reduction of the vehicle.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and
ethanol (also known as grain alco-
hol), and petrol or gasohol containing
methanol (also known as wood alco-
hol) are being marketed along with or
instead of leaded or unleaded petrol.
Do not use gasohol containing more
than 10% ethanol, and do not use
petrol or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any
kind if drivability 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. Gasohol containing more than
10% ethanol.
2. Petrol or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
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 speci-
fied (We recommend that you
consult a HYUNDAI authorised
repairer for details.)
WARNING
• 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.

Introduction
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 gasoline which has an
octane rating of RON(Research
Octane Number) 95 / AKI (Anti Knock
Index) 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, one bottle of additives
added to the fuel tank at every
10,000 miles (15,000 km).
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.
