Introduction
Gasoline engine
Unleaded
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 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. "E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
Hyundai recommends that customers do
not use fuel with an ethanol content
exceeding 10 percent.
FUEL REQUIREMENTS
CAUTION

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 location 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.
(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 to
place 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 vehi-
cle should be maintained until
the filling is complete.
(Continued)(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 by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler 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.

Features of your vehicle
Electronic power steering
Power steering uses the motor to assist
you in steering the vehicle. If the engine
is off or if the power steering system
becomes inoperative, the vehicle may
still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by power steering control unit
which sense 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 the better control of the
steering wheel.
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 illumi-
nate.
• 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.
• The steering effort can suddenly increase, if the operation of EPS sys-
tem is stopped to prevent serious acci-
dents when the malfunction of EPS
system is detected by self-diagnosis.
Tilt steering Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
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.

Parking brake & brakefluid warning
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.
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 it towed to any authorized
Hyundai dealer for a brake system
inspection and necessary repairs. Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems 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 switch
is in the ON position.
Front fog light indicator
(if equipped)
This light comes on when the front fog
lights are ON.
Automatic transaxle posi- tion indicator light (if equipped)
This indicator displays which automatic
transaxle shift position is selected.
Manual transaxle shiftindicator (if equipped)
This indicator informs you which gear is
desired while driving to save fuel.
For example:
: Indicates that shifting up to the 3rdgear is desired (currently the shift
lever is in the 2nd gear).
: Indicates that shifting down to the 3rd gear is desired (currently the
shift lever is in the 4th gear).
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.
