FUEL RECOMMENDATIONS
B010A02L
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.
B010A03A-AATUse Unleaded GasolineUnleaded 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.
B010C01A-AATUse of MTBEHyundai 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 MethanolFuels 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 illu-
minate.

WARNING:
o If you open the fuel filler cap during high
ambient temperatures, a slight "pres-
sure sound" may be heard. This is nor-
mal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Make sure the fuel filler cap is replaced
and securely seated after fueling. Failure
to replace or fully seat the fuel filler cap
will result in fuel vapors escaping into
the atmosphere and the MIL indicator
illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o Automotive fuels are flammable/explo-
sive materials. When refueling, please
note the following guidelines carefully.
o Before touching the fuel nozzle or fuel
filler cap, have one's hands in contact
with metal parts away from the filler neck
to discharge static electricity.
o Do not get back in the vehicle while
refueling. Do not operate anything that
can produce static electricity. Static elec-
tricity discharge can ignite fuel vapors
resulting in explosion.

charge from the container can ignite fuel
vapors causing a fire. While starting re-
fueling contact should be maintained
until the filling is complete.
o Do not use cellular phones around a gas
station. The electric current or electronic
interference from cellular phones can
ignite fuel vapors causing a fire.
o When refueling always shut the engine
off. Sparks by electrical equipment of
the engine can ignite fuel vapors caus-
ing a fire. After refueling, check to make
sure the fuel filler cap is securely closed,

DRIVING YOUR HYUNDAI
212
Refer to your vehicle’s tire and loading
information label for specific informa-
tion about your vehicle’s capacity weight
and seating positions. The combined
weight of the driver, passengers and
cargo should never exceed your
vehicle’s capacity weight.
!
This label also tells you the maximum
weights that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the
actual loads on your front and rear
axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out
your load equally on both sides of the
centerline.
WARNING:
o Never exceed the GVWR for your
vehicle, or the GAWR for either the
front or rear axle.
o Do not load your vehicle any
heavier than the GVWR, or either
the maximum front or rear GAWR.
If you do, parts on your vehicle
can break, and it can change the
way your vehicle handles. This
could cause you to lose control
and crash. Also, overloading can
shorten the life of your vehicle.
C190G01L-AATCompliance LabelThe compliance label is located on the
driver's side of the center piller outer
panel.
The label shows the size of your original
tires and the inflation pressures needed
to obtain the gross weight capacity of
your vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the ve-
hicle, all occupants, fuel and cargo.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
F060J01A-AATo Spark plugsMake sure to install new spark plugs of the
correct heat range.F060H01A-AATo Air cleaner filterA Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.F060G01A-AATo Vapor Hose and Fuel Filler CapThe vapor hose and fuel filler cap should be
inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AATo Vacuum, Crankcase
Ventilation HosesInspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions,
and excessive swelling indicate deterioration.
Particular attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechanical
wear. Inspect all hose connections, such as
clamps and couplings, to make sure they are
secure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.
F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.F060A01A-AAT
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed at the
intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.

CHECKING THE ENGINE OIL
G030D01A-AATAdding OilIf the oil level is close to or below the "LOW"
mark, add oil until it reaches the "FULL" mark.
To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "FULL" and "LOW"
marks is equal to about 1 quart of oil.
G030A01A-AATEngine oil is essential to the performance and
service of the engine. It is suggested that you
check the oil level at least once a week in normal
use and more often if you are on a trip or driving
in severe conditions.
G030C02A-AATTo Check the Oil Level
G030B01A-AATRecommended OilSH, SG or SG/CD (API) multi-grade and fuel
efficient oil is recommended.Before checking the oil, warm up the engine to
the normal operating temperature and be sure
your car is parked on level ground. Turn the
engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and withdraw
it again. Then note the highest level the oil has
reached on the dipstick. It should be between
the upper ("FULL") and lower ("LOW") range.
