Introduction
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."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. Genesis
Branded Vehicle recommends that
customers do not use fuel with an
ethanol content exceeding 15 per-
cent.
✽ ✽
NOTICE
To prevent damage to your vehicle’s
engine and fuel system:
• Never use gasohol which contains
methanol.
• Never use gasohol containing
more than 15% ethanol.
• Never use leaded fuel or leaded
gasohol.
• Never use "E85" fuel.
Your New Vehicle Limited
Warranty does not cover damage to
the fuel system or any performance
problems caused by the use of
"E85" fuel.
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Tighten the cap until it clicks
one time, otherwise the Check
Engine light will illuminate.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
Never add any fuel system
cleaning agents to the fuel tank
other than what has been spec-
ified. (Consult an authorized
retailer of Genesis Branded
products for details.)

- The smart key is close to a radio
transmitter such as a radio sta-
tion or an airport which can
interfere with normal operation
of the transmitter.
- The smart key is near a mobile
two way radio system or a cellu-
lar phone.
- Another vehicle's smart key is
being operated close to your
vehicle.
• The detecting range may decrease
or increase when :
- One side of the tire is raised to
replace a tire or to inspect the
vehicle.
- The vehicle is slantingly parked
on a slope or unpaved road, etc.
Fuel filler door

from inside the vehicle by pushing
the fuel filler door opener button.
1. Turn the engine off.
2. Push the fuel filler door opener
button.3. Pull the fuel filler door (1) out to
fully open.

✽ ✽
NOTICE
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 it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.(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 touch-
ing, 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 danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source, with your bare hand.
(Continued)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.

✽ ✽
NOTICE
• Make sure to refuel your
vehicle according to the "Fuel
Requirements" suggested in the
Introduction chapter.
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces
may damage the paint.
Convenient features of your vehicle
(Continued)
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.
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.
(Continued)
(Continued)
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
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.
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 press the Engine
Start/Stop button to the OFF
position. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.

Emergency fuel filler door release
If the fuel filler door does not open
using the remote fuel filler door
release button, you can open it man-
ually. Pull the handle of the release
located on the left side of the lug-
gage compartment outward slightly.
If the fuel filler cap requires
replacement, use only a
Genesis/Hyundai cap or the
equivalent specified for your
vehicle. An incorrect fuel filler
cap can result in a serious mal-
function of the fuel system or
emission control system.

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
✽ ✽
NOTICE
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by
a low fuel warning light, which
will illuminate when the fuel tank
is nearly empty.
• On inclines or curves, the fuel
gauge pointer may fluctuate or the
low fuel warning light may come
on earlier than usual due to the
movement of fuel in the tank.
If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may
damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to "If the
Engine Overheats" in chapter 6.
CAUTION
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could severely burn.
Wait until the engine is cool
before adding coolant to the
reservoir.

Driving your vehicle
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.
