Introduction
Gasoline engineUnleadedYour new vehicle is designed to use only
unleaded fuel having an Octane Rating
of RON (Research Octane Number) 91 /
AKI (Anti-Knock Index) 87 or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Gasoline containing alcohol and
methanolGasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized Hyundai dealer for
details.)
CAUTION
Do not "top off" after the nozzle
automatically shuts off when
refueling.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

Introduction4 1Use of MTBEWe recommend that fuels containing
MTBE (Methyl Tertiary Butyl Ether) over
15.0% vol. (Oxygen Content 2.7%
weight) should not be used in your vehi-
cle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanolFuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Gasolines for cleaner airTo help contribute to cleaner air, we rec-
ommend that you use gasolines treated
with detergent additives, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine run
cleaner and enhance performance of the
Emission Control System.Operation in foreign countriesIf you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-
istration and insurance.
Determine that acceptable fuel is avail-
able.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and performance problems
that are caused by the use of
methanol or fuels containing
methanol.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol or fuels
containing MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)

Introduction
VEHICLE BREAK-IN PROCESSNo special break-in period is needed. By
following a few simple precautions for the
first 600 miles (1,000 km) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long
periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
Avoid hard stops, except in emergen-
cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3
minutes at one time.
Don't tow a trailer during the first 1,200
miles (2,000 km) of operation.

Safety system of your vehicle
Armrest (if equipped)To use the armrest, pull it forward from
the seatback.
WARNING
For maximum effectiveness in
case of an accident, the headrest
should be adjusted so the middle
of the headrest is at the same
height as the top of the occu-
pant's eyes. The use of a cushion
that holds the body away from
the seatback is not recommend-
ed.
Do not operate the vehicle with
the headrests removed as severe
injury to an occupant may occur
in the event of an accident.
Headrests may provide protec-
tion against severe neck injuries
when properly adjusted.

CAUTION
Make sure the engine is off, the
transaxle is in P and the parking
brake is applied whenever load-
ing or unloading cargo. Vehicle
may move if shift lever is inadver-
tently moved to another position.
Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to pre-
vent it from moving while driving.
Unsecured cargo in the passen-
ger compartment can cause dam-
age to the vehicle or injury to it’s
occupants.

Safety system of your vehicle
WARNING
When you return the rear seatback
to its upright position after being
folded down:
Be careful not to damage the seat
belt webbing or buckle. Do not
allow the seat belt webbing or
buckle to get caught or pinched in
the rear seat. Ensure that the seat-
back is completely locked into its
upright position by pushing on the
top of the seaback. Otherwise, in an
accident or sudden stop, the seat
could fold down and allow cargo to
enter the passenger compartment,
which could result in serious injury
or death.
OHD036124L
CAUTION
- Rear seat belts
When returning the rear seatbacks
to the upright position, remember
to return the rear center shoulder
belt to its proper position.
WARNING
- Cargo
Cargo should always be secured to
prevent it from being thrown about
the vehicle in a collision and caus-
ing injury to the vehicle occupants.
Special care should be taken of
objects placed in the rear seats,
since those may hit the front seat
occupants in a frontal collision.
WARNING -
Cargo loading
Make sure the engine is off, the
transaxle is in P and the parking
brake is applied whenever loading
or unloading cargo. Failure to take
these steps may allow the vehicle
to move if shift lever is inadvertent-
ly moved to another position.

Safety system of your vehicle32 3
Occupant classification systemYour vehicle is equipped with an occu-
pant classification system in the front
passenger's seat.
The occupant classification system is
designed to detect the presence of a
properly-seated front passenger and
determine if the passenger's front air bag
should be enabled (may inflate) or not.
The driver's front air bag is not affected
or controlled by the occupant classifica-
tion system.
WARNING
If an air bag deploys, there may
be a loud noise followed by a fine
dust released in the vehicle.
These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarm
water and a mild soap after an
accident in which the air bags
were deployed.
(Continued)
(Continued)
The SRS can function only when
the ignition key is in the "ON"
position. If the SRS "AIR BAG"
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 inspected by
an authorized Hyundai dealer.
Before you replace a fuse or dis-
connect a battery terminal, turn
the ignition key to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition key is in the ON position.
Failure to heed this warning will
cause the SRS AIR BAG warning
light to illuminate.
