FUEL 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.
B010A02NF-AATUse Unleaded GasolineUnleaded gasoline with a Pump Octane
Rating of 87 (Research Octane Number 91)
or higher must be used in 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.

BREAKING IN YOUR NEW HYUNDAI
B010F01A-AATOperation in Foreign CountriesIf 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 rec-
ommends 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 per-
formance of the Emission Control System.
B020A01S-AATDuring 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 recom-
mendations during the first 1,200 miles (2,000
km).
o Don't drive faster than 55 MPH (88 km/h).
o While driving, keep your engine speed (rpm,
or revolutions per minute) between 2,000
rpm and 4,000 rpm.
o Use moderate acceleration. Don't start
quickly or depress the accelerator pedal
fully.
o For the first 200 miles (300 km), try to avoid
hard stops.
o Don't lug the engine (in other words, don't
drive so slowly in too high a gear that the
engine "bucks":shift to a lower gear).
o Whether going fast or slow, vary your speed
from time to time.
o Don't let the engine idle longer than 3 minutes
at one time.
o Don't tow a trailer during the first 1,200 miles
(2,000 km) of operation.
B030A01NF-GATFor greater convenience, your Hyundai has
two master keys and a sub key. The master
keys will open all locks on your vehicle. The sub
key will only function in the ignition and the door
locks.
Leaving your sub key with a parking attendant
will ensure that your vehicle's trunk, trunk lid
release, glove box compartment and rear trunk
access may not be unlocked in your absence.NOTE:Before leaving your sub key with a parking
attendant, make sure that the lock knobs of
the rear seatback lock and the trunk lid lock
are switched to the "LOCK" position.
