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.

B190A01NF-AATSEAT BELTS-Front Passenger and Rear
Seat 3-Point System with Combination
Locking Retractor
To Fasten Your BeltCombination retractor type seat belts are in-
stalled in the rear seat positions to help accom-
modate the installation of child restraint systems.
Although a combination retractor is also installed
in the front passenger seat position, Hyundai
strongly recommends that children always be
seated in the rear seat. NEVER place any infant
restraint system in the front seat of the vehicle.
This type of seat belt combines the features of
both an emergency locking retractor seat belt
and an automatic locking retractor seat belt. To
fasten your seat belt, pull it out of the retractor
and insert the metal tab into the buckle. There
will be an audible "click" when the tab locks into
the buckle. When not securing a child restraint,
the seat belt operates in the same way as the
driver's seat belt (Emergency Locking Retrac-
tor Type). It automatically adjusts to the proper
length only after the lap belt portion of the seat
belt is adjusted manually so that it fits snugly
around your hips. When the seat belt is fully
extended from the retractor to allow the instal-
lation of a child restraint system, the seat belt
operation changes to allow the belt to retract, but
not to extend (Automatic Locking Retractor
Type). See page 1-32.
B180A01NF-AATSEAT BELT-Driver's 3-Point System with
Emergency Locking Retractor
To Fasten Your BeltTo fasten your seat belt, pull it out of the retractor
and insert the metal tab into the buckle. There
will be an audible "click" when the tab locks into
the buckle.
The seat belt automatically adjusts to the proper
length only after the lap belt portion is adjusted
manually so that it fits snugly around your hips.
If you lean forward in a slow, easy motion, the
belt will extend and let you move around. If there
is a sudden stop or impact, however, the belt will
lock into position. It will also lock if you try to lean
forward too quickly.
B180A01NF
NOTE:If the driver's seat belt is not fastened when
the ignition key is turned from the "OFF"
position to the "ON" or "START" position,
the seat belt warning light will blink and the
warning chime will sound for approximately
six seconds to remind the driver to fasten
the driver's seat belt.

B240D01NF-AATAdditional Safety PrecautionsoNever let passengers ride in the cargo
area (trunk) or on top of a folded-down
back seat. All occupants should sit upright,
fully back in their seats with their seat belts
on and their feet on the floor.
oPassengers should not move out of or
change seats while the vehicle is mov-
ing. A passenger who is not wearing a seat
belt during a crash or emergency stop can
be thrown against the inside of the vehicle,
against other occupants, or out of the ve-
hicle.
oEach seat belt is designed to restrain one
occupant. If more than one person uses the
same seat belt, they could be seriously
injured or killed in a collision.
oDo not use any accessories on seat
belts. Devices claiming to improve occu-
pant comfort or reposition the seat belt can
reduce the protection provided by the seat
belt and increase the chance of serious
injury in a crash.oPassengers should not place hard or
sharp objects between themselves and
the airbags. Carrying hard or sharp objects
on your lap or in your mouth can result in
injuries if an airbag inflates.
oKeep occupants away from the airbag
covers. All occupants should sit upright, fully
back in their seats with their seat belts on and
their feet on the floor. If occupants are too
close to the airbag covers, they could be
injured if the airbags inflate.
oDo not attach or place objects on or near
the airbag covers. Any object attached to
or placed on the front or side impact airbag
covers could interfere with the proper opera-
tion of the airbags.
oDo not modify the front seats. Modifica-
tion of the front seats could interfere with the
operation of the supplemental restraint sys-
tem sensing components or side impact
airbags.
oDo not place items under the front seats.
Placing items under the front seats could
interfere with the operation of the supple-
mental restraint system sensing compo-
nents and wiring harnesses.
o If the airbags inflate, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring, or other components of the SRS
system. Doing so could result in injury,
due to accidental inflation of the airbags
or by rendering the SRS inoperative.
o If components of the airbag system must
be discarded, or if the vehicle must be
scrapped, certain safety precautions
must be observed. Your Hyundai dealer
knows these precautions and can give
you the necessary information. Failure
to follow these precautions and proce-
dures could increase the risk of personal
injury.
o If you sell your vehicle, make certain that
this manual is transferred to the new
owner.
o If your car was flooded and has soaked
carpeting or water on flooring, you
shouldn't try to start the engine; have
the car towed to an authorized Hyundai
dealer.

WARNING AND INDICATOR LIGHTSB260B01JM-AAT
SRS (Airbag) Warning Light
The SRS warning light comes on for about 6
seconds after the key is turned to the "ON"
position or after the engine is started, after which
it will go out.
This light also comes on when the SRS is not
working properly. If the AIRBAG warning light
does not come on, or continuously remains on
after operating for about 6 seconds when you
turned the ignition key to the "ON" position or
started the engine, or if it comes on while driving,
have the SRS inspected by an authorized
Hyundai dealer.B260D01A-AAT
Turn Signal Indicator Lights
The blinking green arrows on the instrument
panel show the direction indicated by the turn
signals. If the arrow comes on but does not blink,
blinks more rapidly than normal, or does not
illuminate at all, a malfunction in the turn signal
system is indicated. Your dealer should be
consulted for repairs.
B260E01NF-AAT
Seat Belt Reminder Light
and Chime (Driver's side)
The driver's seat belt reminder light blinks and
the warning chime sounds for 6 seconds when
the ignition key is turned from the "OFF" position
to the "ON" or "START" position to remind the
driver to fasten the driver's seat belt.B260F01A-AAT
High Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to the high
beam or flash position.
B260G01A-AAT
Low Oil Pressure Warning Light
CAUTION:
If the low oil pressure warning light stays on
while the engine is running, serious engine
damage may result. The oil pressure warning
light comes on whenever there is insufficient
oil pressure. In normal operation, it should
come on when the ignition switch is turned on,
then go out when the engine is started. If the
oil pressure warning light stays on while the
engine is running, there is a serious malfunc-
tion.
If this happens, stop the car as soon as it is safe
to do so, turn off the engine and check the oil
level. If the oil level is low, fill the engine oil to
the proper level and start the engine again. If
the light stays on with the engine running, turn
the engine off immediately. In any instance
where the oil light stays on when the engine
is running, the engine should be checked by
a Hyundai dealer before the car is driven again.

Parking Brake/Low Brake Fluid
Level Warning Light
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 or some other
safe method.
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.
WARNING:
If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as
soon as possible. Driving your car with a
problem in either the brake electrical sys-
tem or brake hydraulic system is danger-
ous, and could result in a serious injury or
death.Warning Light OperationThe parking brake/brake fluid level warning light
should come on when the parking brake is
applied and the ignition switch is turned to "ON"
or "START". After the engine is started, the light
should go out when the parking brake is re-
leased.
If the parking brake is not applied, the warning
light should come on when the ignition switch is
turned to "ON" or "START", then go out when
the engine starts. If the light comes on at any
other time, you should slow the vehicle and bring
it to a complete stop in a safe location off the
roadway.
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

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.
B260P02Y-GAT
ABS Service Reminder
Indicator (SRI) (If Installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System indicator will come on
and then go off in a few seconds. If the ABS SRI
remains on, comes on while driving, or does not
come on when the key is turned to the "ON"
position, this indicates that there may be a
problem with the ABS.
If this occurs, have your vehicle checked by
your Hyundai dealer as soon as possible. The
normal braking system will still be operational,
but without the assistance of the anti-lock brake
system.
WARNING:
If both the ABS SRI and Parking Brake/
Brake fluid level warning lights remain "ON"
or come on while driving, there may be a
problem with E.B.D. (Electronic Brake Force
Distribution).
If this occurs, avoid sudden stops and have
your vehicle checked by your Hyundai dealer
as soon as possible.
B260N02A-AAT
Check Engine - Malfunction In-
dicator Light (MIL)
This light illuminates when there is a malfunction
of an exhaust gas related component, and the
system is not functioning properly so that the
exhaust gas regulation values are not satisfied.
This light will also illuminate when the ignition key
is turned to the "ON" position, and will go out in a
few seconds after the engine is started. If it
illuminates while driving, or does not illuminate
when the ignition key is turned to the "ON" position,
take your car to your nearest authorized Hyundai
dealer and have the system checked.

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 check engine
" " 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.
- 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.
