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.
3. Leaded fuel or leaded gasohol.

(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.

Warnings and indicators
All warning lights are checked by turning
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.
ECO indicator (if equipped)
The ECO indicator is a system that helps
you to drive economically.
It is displayed if you drive fuel efficiently
to help you improve fuel efficiency.
The ECO indicator (green) will turn on
when you are driving fuel efficiently in
the ECO ON mode.
If you don't want the indicator dis-
played, you can turn the ECO ON
mode to OFF mode by pressing the
TRIP button.
As per ECO ON/OFF Mode operation,
refer to the previous page.
The fuel-efficiency can be changed by the driver's driving habit and road con-dition.
The ECO indicator does not function in P (Park), N (Neutral), and R (Reverse).
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.

Parking brake & brake
fluid warning light
Parking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released while engine is run-ning.
The parking brake warning chime will
sound to remind you that the parking
brake is applied when you are driving
above 6 mph (10 km/h). Always release
the parking brake before you drive.
Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks. 3. Do not drive the vehicle if leaks are
found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switchis in the ON position.
Seat belt warning
As a reminder to the driver, the seat belt
warning light will blink for approximately
6 seconds each time you turn the ignition
switch ON, regardless of belt fastening.
For details, refer to the seat belt on chap- ter 3.
Turn signal indicator
The blinking green arrows on the instru-
ment panel show the direction indicated
by the turn signals. If the arrow comes on
but does not blink, blinks more rapidly
than normal, or does not illuminate at all,
a malfunction in the turn signal system is
indicated. Your dealer should be consult-
ed for repairs.
This indicator also blinks when the haz-
ard warning switch is turned on.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.

If the warning light illuminates while driv- ing:
1. Drive safely to the side of the road and stop.
2. With the engine off, check the engine oil level. If the level is low, add oil as required.
If the warning light remains on after
adding oil or if oil is not available, call an
authorized HYUNDAI dealer.
CAUTION
If the oil pressure warning light stays on while the engine is run-ning, serious engine damage may
result. The oil pressure warninglight comes on whenever there isinsufficient oil pressure. In normaloperation, it should come on when
the ignition switch is turned on,then go out when the engine isstarted. If the oil pressure warning
light stays on while the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn off the engine and check the oil level. Ifthe oil level is low, fill the engine oil
to the proper level and start theengine again. If the light stays onwith the engine running, turn theengine off immediately. In any
instance where the oil light stays onwhen the engine is running, theengine should be checked by anauthorized HYUNDAI dealer before
the car is driven again.
