WARNING  
Illustrations complement the words in this  
manual to best explain how to enjoy your  
vehicle. By reading your manual, you  
learn about features, important safety  
information, and driving tips under vari-  
ous road conditions.  
A WARNING indicates a situation in  
which harm, serious bodily injury or  
death could result if the warning is  
ignored.  
You may use unleaded gasoline with an  
octane rating of RON 91~94/AKI 87~90  
but it may result in slight performance  
reduction of the vehicle.  
Except Europe  
The general layout of the manual is pro-  
vided in the Table of Contents. A good  
place to start is the index; it has an alpha-  
betical listing of all information in your  
manual.  
CAUTION  
Your new vehicle is designed to use only  
unleaded fuel having an Octane Rating  
of RON (Research Octane Number) 91 /  
AKI (Anti-Knock Index) 87 or higher.  
A CAUTION indicates a situation in  
which damage to your vehicle could  
result if the caution is ignored.  
Sections: This manual has nine sections  
plus an index. Each section begins with a  
brief list of contents so you can tell at a  
glance if that section has the information  
you want.  
Your new vehicle is designed to obtain  
maximum performance with UNLEADED  
FUEL, as well as minimize exhaust emis-  
sions and spark plug fouling.  
NOTICE

CAUTION  
Leaded (if equipped)  
Gasoline containing alcohol and  
methanol  
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.  
For some countries, your vehicle is  
designed to use leaded gasoline. When  
you are going to use leaded gasoline,  
ask to an authorized HYUNDAI dealer  
whether leaded gasoline in your vehicle  
is available or not.  
Gasohol, a mixture of gasoline and  
ethanol (also known as grain alcohol),  
and gasoline or gasohol containing  
methanol (also known as wood alcohol)  
are being marketed along with or instead  
of leaded or unleaded gasoline.  
Never add any fuel system cleaning  
agents to the fuel tank other than  
what has been specified. (Consult  
an authorized HYUNDAI dealer for  
details.)  
Octane Rating of leaded gasoline is  
same with unleaded one.  
Do not use gasohol containing more than  
10% ethanol, and do not use gasoline or  
gasohol containing any methanol. Either  
of these fuels may cause drivability prob-  
lems and damage to the fuel system.  
Discontinue using gasohol of any kind if  
drivability problems occur.  
WARNING  
Vehicle damage or driveability problems  
may not be covered by the manufactur-  
er’s warranty if they result from the use  
of:  
• Do not "top off" after the nozzle  
automatically shuts off when  
refueling.  
• Always check that the fuel cap is  
installed securely to prevent fuel  
spillage in the event of an acci-  
dent.  
1. Gasohol containing more than 10%  
ethanol.  
2. Gasoline or gasohol containing  
methanol.  
3. Leaded fuel or leaded gasohol.  
CAUTION  
Never use gasohol which contains  
methanol. Discontinue use of any  
gasohol product which impairs dri-  
vability.

Diesel engine  
Use of MTBE  
Do not use methanol  
A020201AUN  
We recommend that fuels containing  
MTBE (Methyl Tertiary Butyl Ether) over  
15.0% vol. (Oxygen Content 2.7%  
weight) should not be used in your vehi-  
cle.  
Fuels containing methanol (wood alco-  
hol) should not be used in your vehicle.  
This type of fuel can reduce vehicle per-  
formance and damage components of  
the fuel system.  
Diesel fuel  
Diesel engine 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 addi-  
tives, as this will increase wear and  
cause damage to the engine and fuel  
system. The use of non-approved fuels  
and / or fuel additives will result in a limi-  
tation of your warranty rights.  
Fuel containing MTBE over 15.0% vol.  
(Oxygen Content 2.7% weight) may  
reduce vehicle performance and produce  
vapor lock or hard starting.  
A020106AUN  
Gasolines for cleaner air  
To help contribute to cleaner air, we rec-  
ommend that you use gasolines treated  
with detergent additives, which help pre-  
vent deposit formation in the engine.  
These gasolines will help the engine run  
cleaner and enhance performance of the  
Emission Control System.  
CAUTION  
Your New Vehicle Limited Warranty  
may not cover damage to the fuel  
system and any performance prob-  
lems that are caused by the use of  
fuels containing methanol or fuels  
containing MTBE (Methyl Tertiary  
Butyl Ether) over 15.0% vol.  
(Oxygen Content 2.7% weight.)  
Diesel fuel of 52 to 54 cetane is used in  
your vehicle. If two types of diesel fuel  
are available, use summer or winter fuel  
properly according to the following tem-  
perature conditions.  
A020107AUN  
• Above -5°C(23°F) ... Summer type  
diesel fuel.  
• Below -5°C(23°F) ... Winter type diesel  
fuel.  
Operation in foreign countries  
If you are going to drive your vehicle in  
another country, be sure to:  
• Observe all regulations regarding reg-  
istration and insurance.  
Watch the fuel level in the tank very care-  
fully : If the engine stops through fuel fail-  
ure, the circuits must be completely  
purged to permit restarting.  
• Determine that acceptable fuel is avail-  
able.
