During 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
recommendations during the first 1,200 miles
(2,000 km).

minate.
Unleaded gasoline with a Pump Octane Rating
of 87 (Research Octane Number 91) or higher
must be used in your Hyundai.
If leaded gasoline is used, it will cause the
catalytic converter to become ineffective and
the emission control system to malfunction.
This can also result in increased maintenance
expense.
To avoid accidental use of leaded fuel, the
larger nozzle used with leaded gasoline at
service stations cannot be inserted into the fuel
tank opening of your Hyundai.
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.
B010C01A-AATUse of MTBE
Hyundai 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. (Oxy-
gen Content 2.7% weight) may reduce vehicle
performance and produce vapor lock or hard
starting.
B010D01A-AATDo Not Use Methanol
Fuels 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.
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.).
B010F01A-AATOperation in Foreign Countries
If 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
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
performance of the Emission Control System.

KEYS KEYSKEYS KEYS
KEYS
For greater convenience, the same key oper-
ates all the locks in your Hyundai. However,
because the doors can be locked without a key,
carrying a spare key is recommended in case
you accidentally lock one key inside the car.
B030B01A-AATRecord Your Key Number
A code number is stamped on the number plate
that came with the keys to your Hyundai. This
key number plate should not be left with the
keys but kept in a safe place, not in the vehicle.
The key number should also be recorded in a
place where it can be found in an emergency.
If you need additional keys, or if you should lose
your keys, your authorized Hyundai dealer can
make new keys if you can supply the key
number.

WARNING:
Unlocked doors can be dangerous. Before
you drive away (especially if there are chil-
dren in the car), be sure that all the doors
are securely closed and locked so that the
doors cannot be inadvertently opened from
the inside. This helps ensure that the doors 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 quick-
ly 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 min-
utes at one time.
o Don't tow a trailer during the first 1,200 miles
(2,000 km) of operation.

1- 23 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 considerable impact to
the front of the vehicle, it will automatically
deploy the airbags.
Passenger's Airbag
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, thus reducing the
risk of head or chest injury.
B240B04E
The SRS service reminder indicator (SRI) on
the instrument panel will blink for about 6 sec-
onds after the ignition key is turned to the "ON"
position or after the engine is started, after
which the SRI should go out.

After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.

Your Hyundai is equipped with a side impact
airbag in each front seat. The purpose of the
airbag is to provide the vehicle's driver and/or
the front passenger with additional protection
than that offered by the seat belt alone. The
side impact airbags are designed to deploy only
during certain side impact collisions, depend-
ing on the crash severity, angle, speed and
point of impact. The side impact airbag are not
designed to deploy in all side impact situations.

B990A04Y-AATPASSENGER PRESENCE DETECTIONThe passenger presence detection system de-
tects the presence of a passenger in the right
front seat. If no passenger is recognized on the
front passenger seat, the deployment of the
front passenger and/or side airbag and seat
belt pretensioner will be prevented.
This system is designed to prevent the replace-
ment of airbag components that deploy need-
lessly in an accident.
NOTE:Luggage or other cargo heavier than 33 lbs
should not be placed on the passenger front
seat. This can allow the deployment of the
front passenger and/or side air bag in the
case of an accident.
WARNING:The Passenger Presence Detection system
is not intended to prevent airbag deploy-
ment while a child is in the front passenger's
seat. It is intended only as a means to
reduce unnecessary collision damage re-
pair expense by preventing airbag and seat
belt pretensioner deployment when the right
front passenger seat is unoccupied. De-
ployment is still possible if only a few pounds
are placed upon the seat. Therefore, children
must not be transported in the front seat. All
children must be seated in the rear seat and
properly restrained with the vehicle's re-
straint system or a child restraint system
appropriate for the child's size and weight.
