CAUTION: MODIFICATIONS TO YOUR HYUNDAI
Your Hyundai should not be modified in any way. Such modifications may adversely affect the
performance, safety or durability of your Hyundai and may, in addition, violate conditions of the limited
warranties covering the vehicle. Certain modifications may also be in violation of regulations
established by the U.S. Department of Transportation and other federal or state agencies.A080A01S-AAT

Your vehicle is equipped with electronic fuel injection and other electronic components. It is possible
for an improperly installed/adjusted two-way radio or cellular telephone to adversely affect electronic

tions or consult your Hyundai dealer for precautionary measures or special instructions if you choose
to install one of these devices.

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 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.
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 performance 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.
!
UNLEADED

o Do not "top off" after the nozzle auto-
matically shuts off when refueling.
o Tighten the cap until it clicks, otherwise
the "
" check engine light will
illuminate.
o Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

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 reg-
istration 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 perfor-
mance of the Emission Control System.
B020A01S-AATDuring the First 1,200 Miles (1,931
Km)No formal "break-in" procedure is required
with your new Hyundai. However, you can
contribute to the economical operation
and durability of your Hyundai by observing
the following recommendations during the
first 1,200 miles (1,931 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 (322 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 (1,931 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 atten-
dant will ensure that the glove box com-
partment may not be unlocked in your
absence.
