Introduction
DANGER indicates a hazardous
situation which, if not avoided,
will result in death or serious
injury.
DANGER
WARNING indicates a hazardous

could result in death or serious
injury.
WARNING

F6
Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded gasoline with
an octane rating of RON 91-94 / AKI
87-90 but it may result in slight per-
formance reduction of the vehicle. (Do
not use methanol blended fuels)
Except Europe
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. (Do not use methanol
blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize 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
authorized HYUNDAI dealer for
details.)
NOTICE
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

FUEL REQUIREMENTS

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 vapor 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 gasoline which has an
octane rating of RON (Research
Octane Number) 95 / AKI (Anti Knock
Index) 91 or higher (for Europe) or
Octane Rating of RON (Research
Octane Number) 91 / AKI (Anti-Knock
Index) 87 or higher (except Europe).
For customers who do not use good
quality gasolines, and have problems
starting or the engine does not run
smoothly, one bottle of additive added
to the fuel tank is recommended
according to the maintenance sched-
ule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorized HYUNDAI dealer 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.

Maintenance
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.
1. Manufacturer or brand name
Manufacturer or brand name is
shown.
2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
195/65R15 91H
195 - Tire width in millimeters.
65 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
15 - Rim diameter in inches.
91 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the
