Introduction
Your new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) 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 and
methanol
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 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.
(Continued)(Continued)
Do not get back into a vehicle
once 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 vehicle
should 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 warnings
posted 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.

Emergency fuel filler lid release
An emergency fuel filler lid release is
located in the luggage compartment, on
the left side.
If the fuel filler lid does not open using
the remote fuel filler lid release, you can
open it manually. Pull the handle outward
slightly.
(Continued)
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment or 911. Follow any safety
instructions they provide.
CAUTION
Make sure to refuel your vehicle
according to the "Fuel require-
ments" suggested in section 1.
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the
fuel system or emission control
system.
Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted surfaces
may damage the paint.
After refueling, make sure the fuel
cap is installed securely to pre-
vent fuel spillage in the event of
an accident.
CAUTION
Do not pull the handle excessively,
otherwise the luggage area trim or
release handle may be damaged.

ECO GUIDE gauge
This is a gauge to let drivers know
whether the current driving condition is
economical or not. The fuel efficiency is
high in the blue zone but is low in the red
zone.
Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank.
The fuel tank capacity is given in
section 8.The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is near
empty.
On inclines or curves, the fuel gauge
may fluctuate or the low fuel warning light
may come on earlier than usual due to
the movement of fuel in the tank.
OYFH041048NCAUTION
Avoid driving with a very low fuel
level. Running out of fuel could
cause the engine to misfire, damag-
ing the catalytic converter.
WARNING- Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
E level.

Driving your vehicle
Certification label
The certification label is located on
the driver's door sill at the center pil-
lar.
This label shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and
cargo.
This label also tells you the maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating (GAWR).To find out the actual loads on your
front and rear axles, you need to go
to a weigh station and weigh your
vehicle. Your dealer can help you with
this. Be sure to spread out your load
equally on both sides of the center-
line.
The label will help you decide how
much cargo and installed equipment
your vehicle can carry.
If you carry items inside your vehicle
- like suitcases, tools, packages, or
anything else - they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash,
the items will keep going and can
cause an injury if they strike the driv-
er or a passenger.
OBH059070
WARNING -Over loading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
cause an accident or vehicle
damage. You can calculate the
weight of your load by weigh-
ing the items (or people)
before putting them in the
vehicle. Be careful not to over-
load your vehicle.
(Continued)
(Continued)
Do not load your vehicle any
heavier than the GVWR, either
the maximum front or rear
GAWR and vehicle capacity
weight. If you do, parts,
including tires on your vehicle
can break, and it can change
the way your vehicle handles
and braking ability. This could
cause you to lose control and
crash. Also, overloading can
shorten the life of your vehi-
cle.
