2FUEL RECOMMENDATIONS
CAUTION:Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuel
system and any performance problems that
are caused by the use of fuels containing
methanol or fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol. (Oxy-
gen Content 2.7% weight.)
B010B01A-AATWhat About Gasohol?
Gasohol (a mixture of 90% unleaded gasoline
and 10% ethanol or grain alcohol) may be used
in your Hyundai. However, if your engine devel-
ops driveability problems, the use of 100%
unleaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
B010A02A-AAT
Use Unleaded Gasoline
Unleaded gasoline with a Pump Octane
Rating of 87 (Research Octane Number 91)
or higher must be used in your Hyundai.
If leaded gasoline is used, it will cause the
catalytic converter to become ineffective and
the emission control system to malfunction.
This can also result in increased maintenance
expense.
To avoid accidental use of leaded fuel, the larger
nozzle used with leaded gasoline at service
stations cannot be inserted into the fuel tank
opening of your Hyundai.
CAUTION:o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o The fuel cap must be tightened at least
3 clicks, otherwise " " light may
illuminate.
B010C01A-AAT
Use of MTBE
Hyundai recommends that fuels containing
MTBE (Methyl Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight) should not
be used in your Hyundai.
Fuel containing MTBE over 15.0% vol. (Oxygen
Content 2.7% weight) may reduce vehicle per-
formance and produce vapor lock or hard
starting.
B010D01A-AATDo Not Use Methanol
Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel
can reduce vehicle performance and damage
components of the fuel system.

Door Ajar Warning Light
and Chime
The door ajar warning light warns you that a door
is not completely closed and the chime warns
you that the driver's side front door is not
completely closed.
NOTE:To remind you not to lock the key inside the
car, the warning light comes on whenever
the key is in the "LOCK" position and a door
is open. The warning chime only sounds
whenever the key is in the "LOCK" position
and driver's side front door is open. The
chime sounds and the light remains on
until the key is removed from the ignition.
!
B260M01A-AATLow Fuel Level Warning Light
The low fuel level warning light comes on when
the fuel tank is approaching 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.
B260N01A-AAT
Malfunction Indicator Light
This light illuminates when there is a malfunction
of an exhaust gas related component, and the
system is not functioning properly so that the
exhaust gas regulation values are not satisfied.
This light will also illuminate when the ignition key
is turned to the "ON" position, and will go out in
a few seconds. If it illuminates while driving, or
does not illuminate when the ignition key is
turned to the "ON" position, take your car to your
nearest authorized Hyundai dealer and have
the system checked.
B260P02Y-GAT
ABS Service Reminder
Indicator (If installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System indicator will come on
and then go off in a few seconds. If the ABS SRI
remains on, comes on while driving, or does not
come on when the key is turned to the "ON"
position, this indicates that there may be a
problem with the ABS.
If this occurs, have your vehicle checked by
your Hyundai dealer as soon as possible. The
normal braking system will still be operational,
but without the assistance of the anti-lock brake
system.
WARNING:If both the ABS SRI and Parking Brake/
Brake fluid level warning lights remain "ON"
or come on while driving, there may be a
problem with E.B.D. (Electronic Brake Force
Distribution).
If this occurs, avoid sudden stops and have
your vehicle checked by your Hyundai dealer
as soon as possible.
B260C02O-GAT
Traction Control Indicator
Light (If installed)
The traction control indicator changes opera-
tion according to the ignition switch position and
whether or not the system is in operation.
It will also illuminate when the ignition key is
turned to the "ON" position, but should go out
after the engine starts. If the TCS indicator stays
on, take your car to your authorized Hyundai
dealer and have the system checked. See
section 2 for more information about the TCS.

If Engine Doesn't Turn Over or Turns
Over Slowly
D010C01Y-AAT
If Engine Turns Over Normally but Does
Not Start
1. Check fuel level.
2. With the key in the "OFF" position, check all
connectors at ignition, coil and spark plugs.
Reconnect any that may be disconnected or
loose.
3. Check the fuel line in the engine room.
4. If engine still refuses to start, call a Hyundai
dealer or seek other qualified assistance.
D010D01A-AAT
If Engine Stalls While Driving
1. Reduce your speed gradually, keeping a
straight line. Move cautiously off the road to
a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle
will not start, contact a Hyundai dealer or
seek other qualified assistance.
WARNING:If the engine will not start, do not push or
pull the car to start it. This could result in a
collision or cause other damage. In addi-
tion, push or pull starting may cause the
catalytic converter to be overloaded and
create a fire hazard.
1. If your car has an automatic transaxle, be
sure the gear selector lever is in "N" or "P"
and the emergency brake is set.
2. Check the battery connections to be sure
they are clean and tight.
3. Turn on the interior light. If the light dims or
goes out when you operate the starter, the
battery is discharged.
4. Check the starter connections to be sure
they are securely tightened.
5. Do not push or pull the vehicle to start it. See
instructions for "Jump Starting".

3CATALYTIC CONVERTEREGR SYSTEM
!
H010E01Y-AAT
(If installed)
This system helps reduce nitrogen oxides by
recirculating a part of the exhaust gas into the
engine, thereby reducing cylinder combustion
temperature, which results in lower output of
oxides of nitrogen.WARNING:o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, igni-
tion or multiport electronic fuel injec-
tion.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and cre-
ate a fire hazard.
o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter
or any other part of the exhaust system.
o Remember that your Hyundai dealer is
your best source of assistance.
H020A01A-AAT
All Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the exhaust gas.
Exhaust gases passing through the catalytic
converter cause it to operate at a very high
temperature. The introduction of large amounts
of unburned gasoline into the exhaust may
cause the catalytic converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:

!WARNING:o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.
