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.

The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal

require airbag deployment or pre-tensioner seat
belt deployment.

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

result in serious or fatal injury in a crash.
All occupants should sit 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 until the ve-
hicle is parked and the ignition key is
removed.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.

B990A02NF-AATOCCUPANT CLASSIFICATION SYSTEMYour vehicle is equipped with an occupant
classification system in the front passenger's
seat.
The Occupant Classification system is de-
signed to detect the presence of a properly-
seated front passenger and determine if the
passenger's front airbag should be enabled
(may inflate) or not. The driver's front airbag is
not affected or controlled by the Occupant
Classification system.
If the front passenger seat is occupied by a
person that the system determines to be of adult
size, and he/she sits properly (sitting upright
with the seatback in an upright position, cen-
tered on the seat cushion with their seat belt on,

!Always wash all exposed skin areas thor-
oughly with lukewarm water and a mild
soap after an accident in which the
airbags were deployed.
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. 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 If an airbag deploys, there may be a loud
noise followed by a fine dust released in
the vehicle. These conditions are nor-
mal and are not hazardous - the airbags
are packed in this fine powder. The dust
generated during airbag deployment
may cause skin or eye irritation as well as
aggravate asthma for some persons.
WARNING:

1FEATURES OF YOUR HYUNDAI44
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.
