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 con-
taining methanol or fuels containing
MTBE (Methyl Tertiary Butyl Ether) over
15.0% vol. (Oxygen 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 develops 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.

REPLACEMENT OF LIGHT
BULBSG260A02L-GATBefore attempting to replace a light bulb,
be sure the switch is turned to the "OFF"
position.
The next paragraph shows how to reach
the light bulbs so they may be changed. Be
sure to replace the burned-out bulb with
one of the same number and wattage
rating.
See page 6-35 for the wattage descrip-
tions.
!
CAUTION:
o Keep the lights out of contact with
petroleum products, such as oil,
gasoline, etc.
o Be sure to replace the LED type
equipped bulbs with an assembly.
o After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is
caused by the temperature difference
between the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle
during the rain and doesn’t indicate a
problem with your vehicle. If the water
leaks into the lamp bulb circuitry, have
the vehicle checked by an Authorized
Hyundai Dealer.

H010D01NF-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls
exhaust emissions while maintaining good
vehicle performance.G270301AUNVehicle modificationsThis vehicle should not be modified. Modi-
fication of your vehicle could affect its per-
formance, safety or durability and may
even violate governmental safety and
emissions regulations.
In addition, damage or performance prob-
lems resulting from any modification may
not be covered under warranty.G270302AUNEngine exhaust gas precautions
(carbon monoxide)Carbon monoxide can be present with
other exhaust fumes. Therefore, if you smell
exhaust fumes of any kind inside your
vehicle, have it inspected and repaired
immediately. If you ever suspect exhaust
fumes are coming into your vehicle, drive
it only with all the windows fully open. Have

PROPOSITION 65 WARNING:
Engine exhaust and a wide variety of
automobile components and parts, in-
cluding components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of Califor-
nia to cause cancer and birth defects
and reproductive harm. In addition, cer-
tain fluids contained in vehicles and
certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
CATALYTIC CONVERTERH020A01NF-AAT(If Installed)Hyundai vehicle is equipped with a mono-
lith type three-way catalytic converter to
reduce the carbon monoxide, hydrocar-
bons 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:Catalytic Converter

WARNING - Exhaust
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
