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 alco-
hol) 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 con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.

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.

WARNING
(Continued)
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.
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.

Certification label
The certification label is located on
the driver's door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. 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).The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating (GVWR) or the 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. Be
sure to spread out your load equally
on both sides of the centerline.
OBH059070
Overloading
Never exceed the GVWR for
your vehicle, the GAWR for
either the front or rear axle
and vehicle capacity weight.
Exceeding these ratings can
affect your vehicle's handling
and braking ability, and cause
an accident.
Do not overload your vehicle.
Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible
tire failure, increased stop-
ping distances and poor vehi-
cle handling-all of which may
result in a crash.
