Introduction
Gasoline engineUnleadedYour 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.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Gasoline containing alcohol and
methanolGasohol, 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.
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.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline 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 sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized Hyundai dealer for
details.)
CAUTION
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.
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

Features of your vehicle48 4Trunk lid open warning
lightThis warning light illuminates when the
trunk lid is not closed securely with the
ignition in any position.Door ajar warning lightThis warning light illuminates when a
door is not closed securely with the igni-
tion in any position.Low fuel level
warningThis warning light indicates the fuel tank
is nearly empty. When it comes on, you
should add fuel as soon as possible.
Driving with the fuel level warning light on
or with the fuel level below “E” can cause
the engine to misfire and damage the
catalytic converter.
Malfunction indicator lamp
(MIL) (check engine light) This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emission
control system.
This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest
authorized Hyundai dealer and have the
system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized Hyundai dealer promptly.
Low washer fluid level
warning indicatorThis warning light indicates the washer
fluid reservoir is near empty. Refill the
washer fluid as soon as possible.
CAUTION
Prolonged driving with the
Emission Control System
Malfunction Indicator Light
( ) illuminated may cause
damage to the emission control
systems which could effect dri-
vability and/or fuel economy.
If the
Emission
Control System
Malfunction Indicator Light ( )
illuminates, potential catalytic
converter damage is possible
which could result in loss of
engine power. Have the Engine
Control System inspected as soon
as possible by an authorized
Hyundai dealer.

Maintenance
Operating precautions for catalyt-
ic converters Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for gaso-
line engine.
Do not operate the vehicle when there
are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
Do not misuse or abuse the engine.
Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off. Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
Do not modify or tamper with any part
of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized
Hyundai dealer.
Avoid driving with a very low fuel level.
If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING
- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park the vehicle over or
near flammable objects, such as
grass, vegetation, paper, leaves,
etc.
