Introduction
Your new vehicle is designed to use
only unleaded fuel having a pump
octane number ((R+M)/2) of 87 or
higher. (Do not use methanol blend-
ed fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining 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 problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.
Vehicle damage or drivability prob-
lems may not be covered by the
manufacturer’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
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance 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
Never add any fuel system
cleaning agents to the fuel tankother than what has been speci-fied. (Consult an authorizedHYUNDAI dealer for details.)CAUTION
Your New Vehicle LimitedWarranty does not cover dam-age to the fuel system or anyperformance problems causedby the use of “E85” fuel.
CAUTION
Never use gasohol which con-tains methanol. Discontinue useof any gasohol product whichimpairs driveability.
WARNING
Do not "top off" after the noz- zle automatically shuts off
when refueling.
Always check that the fuel cap is installed securely to pre-
vent fuel spillage in the event
of an accident.

SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system. During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot provide
adequate restraint.
Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
Air bags inflate in the event of a severe frontal or side collision to
help protect the occupants from
serious physical injury.
There is no single speed at which the air bags will inflate. Generally,
air bags are designed to inflate
based upon the severity of a colli-
sion and its direction. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/inflation signal.
WARNING
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is
placed in the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on while the
vehicle is in motion.
The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.

Closing the hood
1. Before closing the hood, check the
following:
ment 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 halfway and push down to securely lock in place.
Then double check to be sure the
hood is secure.
WARNING
Before closing the hood,ensure that all obstructions
are removed from the hood
opening.
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 posi-
tion, as vision is obstructed,
which might result in an acci-
dent, and the hood could fall
or be damaged.
WARNING - Support rod
Grasp the support rod in the area wrapped in rubber. The
rubber will help prevent you
from being burned by hot
metal when the engine is hot.
The support rod must be inserted completely into the
hole provided whenever you
inspect the engine compart-
ment. This will prevent the
hood from falling and possi-
bly injuring you.

✽NOTICE
• Make sure to refuel your
vehicle according to the "Fuel
Requirements" suggested in chap-
ter 1.
• Do not spill fuel on the exterior surfaces of the vehicle. Any type of
fuel spilled on painted surfaces
may damage the paint.(Continued)
When refueling, always move
the shift lever to the P (Park)
position (for automatic
transaxle) or first gear or R
(Reverse, for manual transaxle),
set the parking brake, and place
the ignition switch to the
LOCK/OFF position. Sparks
produced by electrical compo-
nents related to the engine can
ignite fuel vapors causing a fire.
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.
Do not over-fill or top-off your vehicle tank, which can cause
gasoline spillage.
(Continued)(Continued)
If a fire breaks out during refu-eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
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.
Always check that the fuel cap is installed securely to pre-
vent fuel spillage in the event
of an accident.
CAUTION
If the fuel filler cap requiresreplacement, use only a genuineHYUNDAI cap or the equivalentspecified for your vehicle. Anincorrect fuel filler cap canresult in a serious malfunctionof the fuel system or emissioncontrol system.

Electric power steering (EPS)
The system assists you with 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.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorized HYUNDAI dealer.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics is complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is placed to the ON or
LOCK/OFF position.
• A motor noise may be heard when the vehicle is at stop or at a low
driving speed.
• When you operate the steering wheel in low temperature, abnor-
mal noise may occur. If tempera-
ture rises, the noise will disappear.
This is a normal condition.
STEERING WHEEL
CAUTION
If the Electric Power Steering
System does not operate nor-mally, the warning light ( ) willilluminate on the instrumentcluster. The steering wheel maybecome difficult to control oroperate. Take your vehicle to anauthorized HYUNDAI dealer andhave the system checked assoon as possible.

Features of your vehicle
Parking Brake & BrakeFluid Warning Light
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.
- If the warning light illuminateswith the parking brake released, it
indicates the brake fluid level is
low.
If the brake fluid level in the reservoir
is low:
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 (For more details,
refer to “Brake Fluid” in chapter 7). Then check all brake components
for fluid leaks. If any leak on the
brake system is found, the warning
light remains on, or the brakes do
not operate properly, do not drive
the vehicle.
In this case, have your vehicle
towed to an authorized HYUNDAI
dealer and inspected.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
WARNING - Parking
Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer.
