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.
!
UNLEADED
FUEL ONLY
WARNING:
o Do not "top off" after the nozzle auto-
matically shuts off when refueling.
o Tighten the cap until it clicks, otherwise
the "
" light will illuminate.
o Always check that the fuel cap is in-
stalled 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 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.

Door Ajar Warning Light and
Chime
The door ajar warning light warns you that a door
is not completely closed and the chime warns
you that the key is in the ignition switch.NOTE :The warning chime only sounds whenever
the key is in the ignition switch and the
driver's side front door is open simulta-
neously. The chime sounds until the key is
removed from the ignition switch or the
driver's side front door is closed.B260M01A-AAT
Low Fuel Level Warning Light
The low fuel level warning light comes on when
the fuel tank is approaching empty. When it
comes on, you should add fuel as soon as
possible. Driving with the fuel level warning light
on or with the fuel level below "E" can cause the
engine to misfire and damage the catalytic
converter.
The brake fluid level warning light indicates that
the brake fluid level in the brake master cylinder
is low and hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications should be
added. After adding fluid, if no other trouble is
found, the car should be immediately and care-
fully driven to a Hyundai dealer for inspection.
If further trouble is experienced, the vehicle
should not be driven at all but taken to a dealer
by a professional towing service.
Your Hyundai is equipped with dual-diagonal
braking systems. This means you still have
braking on two wheels even if one of the dual
systems should fail. With only one of the dual
systems working, more than normal pedal travel
and greater pedal pressure are required to stop
the car. Also, the car will not stop in as short a
distance with only half of the brake system
working. If the brakes fail while you are driving,
shift to a lower gear for additional engine braking
and stop the car as soon as it is safe to do so.
B260J02A-AAT
Charging System Warning Light
The charging system warning light should come
on when the ignition is turned on, then go out
when the engine is running. If the light stays on
while the engine is running, there is a malfunc-
tion in the electrical charging system. If the light
comes on while you are driving, stop, turn off the
engine and check under the hood. First, make
certain the generator drive belt is in place. If it is,
check the tension of the belt. Do this as shown
on page 6-19 by pushing down on the center of
the belt. Have the system checked by your
Hyundai dealer as soon as possible.B260K01S-AAT
Trunk Lid Open Warning Light
This light remains on unless the trunk lid is
completely closed and latched.

B270A01O-AATBRAKE PAD WEAR WARNING SOUNDThe front and rear disc brake pads have wear
indicators that should make a high-pitched
squealing or scraping noise when new pads are
needed. The sound may come and go or be
heard all the time when the vehicle is moving. It
may also be heard when the brake pedal is
pushed down firmly. Excessive rotor damage
will result if the worn pads are not replaced. See
your Hyundai dealer immediately.
B260R01NF-GAT
