Introduction
Your new vehicle is designed to obtain maximum performance with UNLEAD-
ED FUEL, as well as minimize exhaust emissions and spark plug fouling.
Your new vehicle is designed to use only unleaded fuel having an octane num-
ber ((R+M)/2) of 87 (Research Octane Number 91) or higher. For improved
vehicle performance, premium unleaded fuel with an octane number ((R+M)/2)
of 91 (Research Octane Number 96) or higher is recommended. (Do not use

tional information.
NOTICE
• Do not "top off" after the nozzle automatically shuts off when refu-
eling.
• Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an accident.
WARNING

2-40
Safety system of your vehicle
The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner
3. SRS control module
4. Emergency Fastening Device
System
Information
The sensor that activates the SRS air
bag is connected with the pre–tension-
er seat belts. The SRS air bag warning
light on the instrument panel will illu-
minate for approximately 6 seconds
after the Engine Start/Stop button in
the ON position, and then it should
turn off.
If the pre-tensioner is not working
properly, the warning light will illumi-
nate even if the SRS air bag is not mal-
functioning. If the warning light does
not illuminate, stays illuminated or
illuminates when the vehicle is being
driven, have an authorized retailer of
Genesis Branded products inspect the
pre-tensioner seat belts and SRS air
bags as soon as possible.
Information
• Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollovers.
• When the pre-tensioner seat belts
are activated, a loud noise may be
heard and fine dust, which may
appear to be smoke, may be visible
in the passenger compartment.
These are normal operating condi-
tions and are not hazardous.
• Although it is non-toxic, the fine
dust may cause skin irritation and
should not be inhaled for prolonged
periods. Wash all exposed skin areas
thoroughly after an accident in
which the pre-tensioner seat belts
were activated.
• The pre-tensioner seat belt system
may get adversely affected by
installing an audio system to the
center console or welding/painting
the frontal vehicle body.
In this case, consult an authorized
retailer of Genesis Branded prod-
ucts. The air bag warning light illu-
minates, if there is a malfunction
with the pre-tensioner seat belt sys-
tem.
• In following situations, immediately
have the air bag system and the pre-
tensioner seat belt system checked
by an authorized retailer of Genesis
Branded products.
- The air bag warning light does not
illuminate at all after turning ON
the engine.
- The air bag warning light remains
ON over 6 seconds after turning
ON the engine.

Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.
They are designed to help protect the
heads of the front seat occupants
and the rear outboard seat occupants
in certain side impact collisions.
The curtain air bags are designed to
deploy only during certain side
impact collisions, depending on the
crash severity.
The side and curtain air bags on both
sides of the vehicle may deploy if a
rollover or possible rollover is detect-
ed.
However, the curtain air bags are not
designed to deploy in all side impact
or rollover situations. • 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 airbag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
• 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 Vehicle.

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
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.
If your SRS malfunctions, the
air bag may not inflate properly
during 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 or START
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
possible if any of these condi-
tions occur.

STEERING WHEEL
Motor-Driven Power Steering
(MDPS)
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, have the system
checked by an authorized retailer of
Genesis Branded products.
If the Motor-Driven Power Steering
(MDPS) System does not operate
normally, the warning light ( )
will illuminate on the instrument
cluster. You may steer the vehicle,
but it will require increased steer-
ing efforts. Take your vehicle to an
authorized retailer of Genesis
Branded products and have the
system checked as soon as possi-
ble.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after the Engine
Start/Stop button is in the ON posi-
tion.
This happens as the system per-
forms the MDPS system diagnostics.
When the diagnostics is completed,
the steering wheel will return to its
normal condition.
• When the battery voltage is low, you
might have to put more steering
effort. However, it is a temporary
condition so that it will return to
normal condition after charging the
battery.
• A click noise may be heard from the
MDPS relay after the Engine
Start/Stop button is in the ON or
OFF position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driv-
ing speed.
• When you operate the steering
wheel in low temperatures, abnor-
mal noise may occur. If the temper-
ature rises, the noise will disappear.
This is a normal condition.
