Introduction
Your new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 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 andmethanol
Gasohol, 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 drivability 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.

Immobilizer system (if equipped)
Your vehicle may be equipped with an
electronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid or not.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.
To activate the immobilizer system:
Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
To deactivate the immobilizer sys-
tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
✽✽ NOTICE
When starting the engine, do not use the
key with other immobilizer keys around.
Otherwise the engine may not start or
may stop soon after it starts. Keep each
key separately not to have any malfunc-
tion after you receive your new vehicle. ✽
✽
NOTICE
If you need additional keys or lose your
keys, consult an authorized HYUNDAI
dealer.WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave
this number anywhere in your vehi-
cle.
CAUTION
The transponder in your ignition key is an important part of theimmobilizer system. It is designedto give years of trouble-free service,however you should avoid expo-
sure to moisture, static electricityand rough handling. Immobilizersystem malfunction could occur.
CAUTION
Do not put metal accessories near
the ignition switch. The engine maynot start for the metal accessories
may interrupt the transponder sig-nal from normally transmitting.
CAUTION
Do not change, alter or adjust the immobilizer system because itcould cause the immobilizer sys-
tem to malfunction and should onlybe serviced by an authorizedHYUNDAI dealer.
Malfunctions caused by improperalterations, adjustments or modifi-cations to the immobilizer systemare not covered by your vehicle
manufacturer warranty.

Closing the hood
1. Before closing the hood, check the fol-
lowing:
must be correctly installed.
bustible material must be removed
from the engine compartment.
2. Return the support rod to its clip to prevent it from rattling.
3. Lower the hood until it is about 1 ft. (30 cm) above the closed position and let
it drop. Make sure that it locks into
place.WARNING
Before closing the hood, ensure that all obstructions are removed
from the hood opening. Closingthe hood with an obstruction
present in the hood opening may
result in property damage or
severe personal injury.
Do not leave gloves, rags or any other combustible material in the
engine compartment. Doing so
may cause a heat-induced fire.
Always double check to be sure that the hood is firmly latched
before driving away. If it is not
latched, the hood could open
while the vehicle is being driven,
causing a total loss of visibility,
which might result in an accident.
Do not move the vehicle with the hood in the raised position, asvision is obstructed and the hood
could fall or be damaged.

If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Do not "top off" after the nozzle automatically shuts off whenrefueling.

(Continued)
Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced byelectrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure thefiller cap and filler door are
securely closed, before starting
the engine.
DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)(Continued)
Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
When using an approved portable fuel container, be sure toplace the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling has
begun, contact with the vehicleshould be maintained until the
filling is complete.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warningsposted at the gas station facility.
Before refueling, note the loca- tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.

Electric power steering
The power steering uses a motor to
assist you in steering the vehicle. If the
engine is off or if the power steering sys-
tem becomes inoperative, the vehicle
may still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by a power steering control unit
which senses the steering wheel torque,
steering wheel position and vehicle
speed to command the motor.
The steering wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for optimum steering control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
✽✽
NOTICE
The following symptoms may occur dur-
ing normal vehicle operation:
 The EPS warning light does not illu- minate.
 The steering wheel becomes heavier after turning the ignition switch on.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics is completed, the steering
wheel will return to its normal condi-
tion.
 Click noise may be heard from the EPS relay after the ignition switch is
turned to the ON or LOCK position.
 Motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
 If the Electric Power Steering System does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized HYUNDAI dealer and
have the vehicle checked as soon as
possible.
 When you operate the steering wheel in low temperature, abnormal noise
could occur. If temperature rises, the
noise will disappear. This is a normal
condition. Tilt steering/Telescope steering (if equipped)
Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise the steering wheel to give your
legs more room when you exit and enter
the vehicle (if equipped).
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
WARNING
Never adjust the angle and height of steering wheel while driving.
You may lose your steering con-
trol and cause severe personal
injury or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.

the ignition switch ON (do not start the
engine). Any light that does not illuminate
should be checked by an authorized
HYUNDAI dealer.
After starting the engine, check to make
sure that all warning lights are off. If any are still on, this indicates a situation that
needs attention. When releasing the
parking brake, the brake system warning
light should go off. The fuel warning light
will stay on if the fuel level is low.

“Active ECO” in chapter 5.
Air bag warning light
This warning light will illuminate for
approximately 6 seconds each time you
turn the ignition switch to the ON posi- tion. This light also comes on when the
Supplemental Restraint System (SRS) is
not working properly. If the AIR BAG
warning light does not come on, or con-
tinuously remains on after operating for
about 6 seconds when you turned the
ignition switch to the ON position or start-
ed the engine, or if it comes on while
driving, have the SRS inspected by an
authorized HYUNDAI dealer.
Anti-lock brake system(ABS) warning light
This light illuminates if the ignition switch
is turned ON and goes off in approxi-
mately 3 seconds if the system is operat-
ing normally.
If the ABS warning light remains on,
comes on while driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a malfunction with the
ABS.
If this occurs, have your vehicle checked
by an authorized HYUNDAI dealer as
soon as possible. The normal braking
system will still be operational, but with-
out the assistance of the anti-lock brake system.
