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.)
CAUTION

Safety system of your vehicle
To reduce the risk of serious
injury or death from an inflating
side air bag, take the following
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.
Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
Hold the steering wheel at the
9 o'clock and 3 o'clock posi-
tions, to minimize the risk of
injuries to your hands and
arms.
Do not use any accessory
seat covers. This could reduce
or prevent the effectiveness
of the system.
(Continued)
WARNING (Continued)
Do not hang other objects
except clothes on the clothes
hanger. In an accident it may
cause vehicle damage or per-
sonal injury especially when
airbag is inflated.
Do not place any objects over
the air bag or between the air
bag and yourself. Also, do not
attach any objects around the
area the air bag inflates such
as the door, side door glass,
front and rear pillar.
Do not place any objects
between the door and the
seat. They may become dan-
gerous projectiles if the side
air bag inflates.
Do not install any accessories
on the side or near the side air
bags.
Do not put any objects
between the side air bag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
(Continued)
(Continued)
Do not cause impact to the
doors when the Engine Start/
Stop button is in the ON posi-
tion or this may cause the
side air bags to inflate.
If the seat or seat cover is
damaged, have the vehicle
checked and repaired by an
authorized retailer of Genesis
Branded products.

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 elec-
trical system for malfunctions. The
light indicates that there is a potential
problem with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.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. When needed,
the side air bags help provide protec-
tion in the event of a side impact or
rollover by supporting the side upper
body area.
Air bags are activated (able to
inflate if necessary) only when the
Engine Start/Stop button 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.
If your SRS malfunctions, the air
bag may not inflate properly dur-
ing 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 Engine Start/Stop
button is 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 retailer of
Genesis Branded products
inspect the SRS as soon as pos-
sible if any of these conditions
occur.

Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
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 retailer of Genesis
Branded products.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the
Engine Start/Stop button 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 Engine
Start/Stop button is in the ON or
OFF position.
• 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.
Tilt steering / Telescope steering
Adjust the steering wheel so it points
toward your chest, not toward your
face. Make sure you can see the
instrument panel warning lights and
gauges. After adjusting, push the
steering wheel both up and down to
be certain it is locked in position.
Always adjust the position of the
steering wheel before driving.
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. The steering wheel will
require increase effort. Take
your vehicle to an authorized
retailer of Genesis Branded
products and have the system
checked as soon as possible.
CAUTION
NEVER adjust the steering
wheel while driving. This may
cause loss of vehicle control
resulting in an accident.
