RESPONSIBILITY FOR MAINTENANCE
The maintenance requirements for your new Hyundai are found in Section 5. As the owner,
it is your responsibility to see that all maintenance operations specified by the manufacturer
are carried out at the appropriate intervals. When the vehicle is used in severe driving
conditions, more frequent maintenance is required for some operations. Maintenance
requirements for severe operating conditions are also included in Section 5.

B020A01S-AATBREAKING IN YOUR NEW HYUNDAI
During the First 1,200 Miles (2,000 Km)
No formal "break-in" procedure is required with
your new Hyundai. However, you can contrib-
ute to the economical operation and durability
of your Hyundai by observing the following
recommendations during the first 1,200 miles
(2,000 km).

minate.
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.
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.
B010C01A-AATUse 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. (Oxy-
gen Content 2.7% weight) may reduce vehicle
performance 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.
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.).
B010F01A-AATOperation in Foreign Countries
If you are going to drive your Hyundai in another
country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available.
B010E01A-AATGasolines for Cleaner AirTo help contribute to cleaner air, Hyundai
recommends that you use gasolines treated
with detergent additives, which help prevent
deposit formation in the engine. These gasolines
will help the engine run cleaner and enhance
performance of the Emission Control System.

The Positive Crankcase Ventilation System is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies fresh filtered air to
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through the
PCV valve and into the induction system.

EMISSION CONTROL SYSTEMYour Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-

There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this

All Hyundai vehicles are equipped with one or
two monolith type three-way catalytic convert-
ers to reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the ex-
haust 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:
