!
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 ex-
pense.
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.
B010B01A-AAT
What 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% un-
leaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
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 start-
ing.
B010D01A-AAT
Do 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.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 ill-
uminate.
CAUTION:Your Hyundai's New Vehicle Limited Warran-
ty 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. (Oxygen Content 2.7%
weight.)

WHAT TO DO IN AN EMERGENCY
IF THE ENGINE WILL NOT START
!
D010B02A-AAT
If Engine Doesn't Turn Over or Turns
Over Slowly
D010A01A-AATD010C01A-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 the engine still refuses to start, call a
Hyundai dealer or seek other qualified assis-
tance.
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 addition,
push or pull starting may cause the catalytic
converter to be overloaded and create a fire
hazard.
D010B01AD010C01A-D
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".

!!
H020A01A-AAT
All Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to
reduce the carbon monoxide, hydrocarbons
and nitrogen oxides contained in the exhaust
gas. Exhaust gases passing through the cata-
lytic converter cause it to operate at a very
high temperature. The introduction of large
amounts of unburned gasoline into the ex-
haust may cause the catalytic converter to
overheat and create a fire hazard. This risk
may be reduced by observing the following:
WARNING:o Remember that your Hyundai dealer is
your best source of assistance.
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.
HLC5022Catalytic ConverterWARNING:
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 create
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.
