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 con-
taining methanol or fuels containing
MTBE (Methyl Tertiary Butyl Ether) over
15.0% vol. (Oxygen 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 develops 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 performance 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.

SEAT BELTSB150B04Y-AATInfant or Small ChildAll 50 states have child restraint laws. You
should be aware of the specific
requirements in your state. Child and/or
infant safety seats must be properly placed
and installed in the rear seat. Information
about the use of these restraints begins on
page 1-27.
!
B150A02S-AATSEAT BELT PRECAUTIONS
WARNING:All occupants of the vehicle must wear
their seat belts at all times. Seat belts
and child restraints reduce the risk of
serious or fatal injuries for all occupants
in the event of a collision or sudden stop.
Without a seat belt, occupants could be
shifted too close to a deploying airbag,
strike the interior structure or be thrown
from the vehicle. Properly worn seat
belts greatly reduce these hazards. Even
with advanced airbags, unbelted
occupants can be severely injured by a
deploying airbag. Always follow the
precautions about seat belts, airbags
and occupant safety contained in this
manual.
!
WARNING:
Every person in your vehicle needs to be
properly restrained at all times, including
infants and children. Never hold a child
in your arms or lap when riding in a
vehicle. The violent forces created
during a crash will tear the child from
your arms and throw the child against
the interior. Always use a child restraint
appropriate for your child's height and
weight, see page 1-27.NOTE:Small children are best protected from
injury in an accident when properly re-
strained in the rear seat by a child
restraint system that meets the
requirements of the Federal Motor
Vehicle Safety Standards. Before buying
any child restraint system, make sure
that it has a label certifying that it meets
Federal Motor Vehicle Safety Standard
213. The restraint must be appropriate
for your child's height and weight. Check
the label on the child restraint for this
information. See information beginning
on page 1-29.

B140A01S-AATREAR SEAT WARNINGFor the safety of all passengers, luggage
or other cargo should not be piled higher
than the top of the seatback. In addition,
do not place objects on the rear shelf as
they may move forward during braking
or in an accident and may strike and
injure vehicle passengers.

B990A04NF-AATMain components of occupant clas-
sification systemo A detection device located within the
front passenger seat cushion.
o Electronic system to determine whether
passenger air bag systems (both front
and side) should be activated or deac-
tivated.
o A warning light located on the instru-
ment panel which illuminates the words
"PASSENGER AIR BAG OFF" indicat-
ing the front passenger air bag system
is deactivated.
o The instrument panel air bag warning
light is interconnected with the occu-
pant 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 (sit-
ting upright with the seatback in an upright
position, centered on the seat cushion with
their seat belt on, legs comfortably ex-
tended and their feet on the floor), the
"PASSENGER AIR BAG OFF" indicator
will be turned off and the front passenger's
air bag will be able to inflate, if necessary,
in frontal crashes.
You will find the "PASSENGER AIR BAG
OFF" indicator on the center facia panel.
This system detects the conditions 1~4 in
the following table and activates or
deactivates the front passenger air bag
based on these conditions.
ONF038024N
Always be sure that you and all vehicle
occupants are seated and restrained prop-
erly (sitting upright with the seat in an
upright position, centered on the seat cush-
ion, with the person’s legs comfortably
extended, feet on the floor, and wearing
the safety belt properly) for the most effec-
tive protection by the air bag and the safety
belt.
o The OCS (Occupant Classification Sys-
tem) may not function properly if the
passenger takes actions which can
defeat the detection system. These in-
clude:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center
console.
(3) Sitting towards the sides or the front
of the seat.
(4) Putting legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.

*1) The system judges a person of adult
size as an adult. When a smaller adult
sits in the front passenger seat, the
system may recognize him/her as a
child depending on his/her physique
and posture.
*2) Do not allow children to ride in the front
passenger seat. When a larger child
who has outgrown a child restraint sys-
tem sits in the front passenger seat, the
system may recognize him/her as an
adult depending on his/her physique
or posture.
*3) Never install a child restraint system on
the front passenger seat.

!
WARNING:
o Even though your vehicle is equipped
with the occupant classification sys-
tem, never install a child restraint
system in the front passenger's seat.
A deploying air bag can forcefully
strike a child resulting in serious inju-
ries or death. Any child age 12 and
under should ride in the rear seat.
Children too large for child restraints
should use the available lap/shoulder
belts. No matter what type of crash,
children of all ages are safer when
restrained in the rear seat.
o If the "PASSENGER AIR BAG OFF"
indicator 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 Do not modify or replace the front
passenger seat. Don't place anything
on or attach anything such as a blanket
or after market seat heater to the
front passenger seat. This can
adversely affect the occupant classi-
fication system.
o Do not sit on sharp objects such as tools
when occupying the front passenger
seat. This can adversely affect the occu-
pant classification system.
o Do not use accessory seat covers on
the front seats.
o Accident statistics show that children
are safer if they are restrained in the
rear, as opposed to the front seat. It is
recommended that child restraints be
secured in a rear seat, including an infant
riding in a rear-facing infant seat, a child
riding in a forward-facing child seat and
an older child riding in a booster seat.
o Air bags can only be used once – have
an authorized Hyundai dealer replace
the air bag immediately after
deployment.
o A smaller-stature adult who is not seated
correctly (for example: seat excessively
reclined, leaning on the door or center
console or hips shifted forward in the
seat) can cause a condition where the
advanced frontal air bag system senses
less weight than if the occupant were
seated properly (sitting upright with the
seatback in an upright position, cen-
tered on the seat cushion with their seat
belt on, legs comfortably extended and
their feet on the floor). This condition can
result in an adult potentially being
misclassified and illumination of the
"PASSENGER AIR BAG OFF" indicator.
B990B05Y-AATSide Impact AirbagYour 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, depending
on the crash severity, angle, speed and
point of impact. The side impact airbags
are not designed to deploy in all side
impact situations.

o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than
necessary. If you are waiting (and not in
traffic), turn off your engine and restart
only when you're ready to go.
o Remember, your Hyundai does not re-
quire extended warm-up. After the en-
gine has started, allow the engine to run
for 10 to 20 seconds prior to placing the
vehicle in gear. In very cold weather,
however, give your engine a slightly
longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoided
by shifting at the recommended speeds.
o Use your air conditioning sparingly. The
air conditioning system is operated by
engine power so your fuel economy is
reduced when you use it. o Take care of your tires. Keep them
inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment can result
from hitting curbs or driving too fast over
irregular surfaces. Poor alignment
causes faster tire wear and may also
result in other problems as well as
greater fuel consumption.
o Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 5. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section 5
for details).
o Keep your car clean. For maximum
service, your Hyundai should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel
consumption and also contribute to cor-
rosion.
DRIVING FOR ECONOMYC140A02A-AATYou can save fuel and get more miles from
your car if you follow these suggestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-rabbit"
starts or full-throttle shifts and maintain
a steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance
from other vehicles so you can avoid
unnecessary braking. This also reduces
brake wear.
o Drive at a moderate speed. The faster
you drive, the more fuel your car uses.
Driving at a moderate speed, especially
on the highway, is one of the most
effective ways to reduce fuel
consumption.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and
also increase wear on these
components. In addition, driving with
your foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.

C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can
build up under the fenders and interfere
with the steering. When driving in severe
winter conditions where this may happen,
you should periodically check underneath
the car to be sure the movement of the front
wheels and the steering components is
not obstructed.C160I01A-AATDon't Let Your Parking Brake FreezeUnder some conditions your parking brake
can freeze in the engaged position. This
is most likely to happen when there is an
accumulation of snow or ice around or
near the rear brakes or if the brakes are
wet. If there is a risk the parking brake may
freeze, apply it only temporarily while you
put the gear selector lever in "P" (automatic)
or in first or reverse gear (manual transaxle)
and block the rear wheels so the car cannot
roll. Then release the parking brake.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from Hyundai dealers and most
auto parts outlets. Do not use engine coolant
or other types of anti-freeze as these may
damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the
key opening. If a lock is covered with ice,
squirt it with an approved de-icing fluid to
remove the ice. If the lock is frozen internally,
you may be able to thaw it out by using a
heated key. Handle the heated key with
care to avoid injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in
Section 6 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not cracked,
worn or damaged in any way.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a
lower viscosity "winter weight" oil be used
during cold weather. See Section 9 for
recommendations. If you aren't sure what
weight oil you should use, consult your
Hyundai dealer.
