NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage. Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Your new vehicle is designed to use
only unleaded fuel having an octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher. (Do not
use methanol blended fuels)
To prevent damage to the engine
and engine components, never
add any fuel system cleaning
agents to the fuel tank other than
what has been specified.
Consult an authorized HYUNDAI
dealer for additional information.
Gasoline containing alcohol or
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol)
are being marketed along with or
instead of leaded or unleaded gaso-
line. For example, "E15" is a gasohol
comprised of 15% ethanol and 85%
gasoline.
Do not use gasohol containing more
than 15% 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 control
system and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
NOTICE
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,

Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, deter-
gent-based fuel additives that you
can purchase separately may be
added to the gasoline. If TOP TIER
Detergent Gasoline is not available,
one bottle of additive added to the
fuel tank according to the mainte-
nance schedule is recommended
(refer to the Maintenance Schedule
in chapter 7).
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices. By following a few simple precau-
tions for the first 600 miles (1,000
km) you may add to the perform-
ance, economy and life of your vehi-
cle.
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 emer- gencies, to allow the brakes to seat
properly.

Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise until it "clicks" one time.
2. Close the fuel filler door until it is latched securely.
Information
• Tighten the cap until it clicks once,otherwise the fuel cap open warn-
ing indicator light will illuminate.
• There may be an intermittent noise near the refueling hole while the
engine is idling if the fuel cap is not
closed securely. This occurs nor-
mally with the OBD system.
• When refueling on unleveled ground, the fuel gauge may not
point to the F position. It is not a
malfunction. If you move your
vehicle to a level ground, the fuel
gauge will move to the full position.

Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
WARNING

Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components 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.
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.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
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 between your bare
hand and the vehicle should
be maintained until the filling
is complete.
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.
