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.
B010A01NF-AATUse Unleaded GasolineUnleaded gasoline with a Pump Octane
Rating of 87 (Research Octane Number 91)
or higher must be used in your 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.

Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Further
opening of the covers then allows full inflation of
the airbags.A fully inflated airbag, in combination with a
properly worn seat belt, slows the driver's or the
passenger's forward motion, reducing the risk
of head and chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility and the ability to steer or
operate other controls.

11.Side Impact Sensor

13.Side Impact Airbag Module
14.Curtain Airbag Module
The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal
or near-frontal impact is severe enough to
require airbag deployment or pre-tensioner seat
belt deployment.
The SRS "AIRBAG" warning light on the instru-
ment panel will illuminate for about 6 seconds
after the ignition key is turned to the "ON"
position or after the engine is started, after which
the "AIRBAG" warning light should go out.The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box. When
the SRSCM detects a sufficiently severe impact
to the front of the vehicle, it will automatically
deploy the front airbags.

o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS "AIRBAG" warning light does not
illuminate, or continuously remains on
after illuminating for about 6 seconds
when the ignition key is turned to the
"ON" position, or after the engine is
started, comes on while driving, the SRS
is not working properly. If this occurs,
have your vehicle immediately inspect-
ed by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position and remove the
ignition key. Never remove or replace the
airbag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS
"AIRBAG" warning light to illuminate. Passenger's Front Airbag
CAUTION:
o Do not install or place any accessories
(drink holder, cassette holder, sticker,
etc.) on the front passenger's panel
above the glove box in a vehicle with a
passenger's airbag. Such objects may
become dangerous projectiles and cause
injury if the passenger's airbag inflates.
o When installing a container of liquid air
freshener inside the vehicle, do not place
it near the instrument cluster nor on the
instrument panel surface. If there is any
leakage from the air freshener onto these
areas (instrument cluster, instrument
!
B240B04NF
panel or air ventilator), it may damage
these parts. If the liquid from the air
freshener does leak onto these areas,
wash them with water immediately.
WARNING:
o When the SRS is activated, there may be
a loud noise and fine dust will be re-
leased throughout the vehicle. These
conditions are normal and are not haz-
ardous. However, the fine dust generat-
ed during airbag deployment may cause
skin irritation. Wash all exposed skin
areas thoroughly with lukewarm water
and a mild soap after an accident in
which the airbags were deployed.
WARNING:
NOTE:
Your vehicle's Supplemental Restraint Sys-
tem Control Module is equipped a record-
ing device which may record the use of the
seat belt restraint system by the driver and
front passenger in certain collisions.

NOTE:The "PASSENGER AIR BAG OFF" indicator
illuminates for about 6 seconds after the
ignition key is turned to the "ON" position
or after the engine is started. If the front
passenger seat is occupied, the occupant
classification sensor will then classify the
front passenger within approximately 10
seconds after the ignition is turned on.
CAUTION:
If the occupant classification system is not
working properly, the SRS airbag warning
light on the instrument panel will
illuminate because the passenger's front
airbags are connected with the occupant
classification system. If there is a malfunc-
tion of the occupant classification system,
the "PASSENGER AIR BAG OFF" indicator
will not illuminate and the passenger's front
airbags will inflate in frontal impact crashes
even if there is no occupant in the front
passenger's seat. If the SRS airbag warning
light does not illuminate when the ignition
key is turned to the "ON" position, remains
illuminated after approximately 6 seconds
when the ignition key is turned to the "ON"
position, or if it illuminates while the vehicle
is being driven, have an authorized Hyundai
dealer inspect the occupant classification
system and the SRS airbag system as soon
as possible.
!
WARNING:
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint sys-
tem in the front passenger's seat. A child
restraint system must never be placed in
the front seat. Children who are too large
for child restraint systems should al-
ways occupy the rear seat and use the
available lap/shoulder belts. Children are
afforded the most safety in the event of
an accident when they are restrained by
a proper restraint system in the rear seat.
o If the "PASSENGER AIR BAG OFF" indi-
cator is illuminated when the front
passenger's seat is occupied by an adult
and he/she sits properly (sitting upright
with the seatback in an upright position,
centered on the seat cushion with their
seat belt on, legs comfortably extended
and their feet on the floor), have that
person sit in the rear seat.
o If you change the weight on the front
passenger seat just after sit-in or restart
of the engine, the "PASSENGER AIR
BAG OFF" indicator may be turned on or
off for a few seconds, disabling or en-
abling the passenger airbags. After the
initial stage of about 30 seconds, the
"PASSENGER AIR BAG OFF" indicator
will not toggle.
When an adult is seated in the front passenger
seat, if the "PASSENGER AIR BAG OFF" indica-
tor is on, turn the ignition key to "LOCK" and ask
the passenger to sit properly (sitting upright with
the seat back in an upright position, centered on
the seat cushion with their seat belt on, legs
comfortably extended and their feet on the
floor). Restart the engine and have the person
remain in that position for about 30 seconds. This
will allow the system to detect the person and to
enable the passenger airbag. If the "PASSEN-
GER AIR BAG OFF" indicator is still on, turn the
ignition key to "LOCK" and ask the passenger to
sit properly and restart the engine again.
If the "PASSENGER AIR BAG OFF" indicator is
still on, ask the passenger to move to the rear
seat. After the vehicle starts, the "PASSENGER
AIR BAG OFF" indicator will not change accord-
ing to the passenger's posture.Normal position
