Introduction
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 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.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask to an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane Rating of leaded gasoline is
same with unleaded one.
WARNING
• Do not "top off" after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized HYUNDAI dealer for
details.)
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

Electronic active headrest
The electronic active headrest is
designed to trigger the headrest forward
and upward when impact sensor detects
a rear impact. This helps to prevent the
driver's and front passenger’s heads
from moving backward and thus helps
minimize neck injuries.Seat warmer (if equipped)
The seat warmer is provided to warm the
front seats during cold weather. While the
engine is running, push either of the
switches to warm the driver's seat or the
front passenger's seat.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the switches in the
OFF position.
OBH038069
WARNING
Do not operate the vehicle with the
headrests removed as severe injury
to the occupants may occur in the
event of an accident. Headrests
may provide protection against
neck injuries when properly adjust-
ed.
WARNING
Make sure the headrest locks in
position after adjusting it to proper-
ly protect the occupants.
CAUTION
The active headrest is a safety
device to reduce injuries from a
rear impact. Do not hit or pull the
headrest intentionally.

✽NOTICE
Because the sensor that activates the
SRS air bag is connected with the pre-
tensioner seat belt, the SRS air bag
warning light on the instrument
panel will illuminate for approximately
6 seconds after the ignition switch has
been turned to the ON position, and
then it should turn off.
CAUTION
If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no
malfunction of the SRS air bag. If
the SRS air bag warning light does
not illuminate when the ignition
switch is turned to ON, or if it
remains illuminated after illuminat-
ing for approximately 6 seconds, or
if it illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the pre-
tensioner seat belt and SRS air bag
system as soon as possible.
WARNING
• Pre-tensioners are designed to
operate only one time. After acti-
vation, pre-tensioner seat belts
must be replaced. All seat belts,
of any type, should always be
replaced after they have been
worn during a collision.
• The pre-tensioner seat belt
assembly mechanisms become
hot during activation. Do not
touch the pre-tensioner seat belt
assemblies for several minutes
after they have been activated.
• Do not attempt to inspect or
replace the pre-tensioner seat
belts yourself. This must be done
by an authorized HYUNDAI deal-
er.
• Do not strike the pre-tensioner
seat belt assemblies.
• Do not attempt to service or
repair the pre-tensioner seat belt
system in any manner.
(Continued)
(Continued)
• Improper handling of the pre-ten-
sioner seat belt assemblies, and
failure to heed the warnings not
to strike, modify, inspect, replace,
service or repair the pre-tension-
er seat belt assemblies may lead
to improper operation or inadver-
tent activation and serious injury.
• Always wear the seat belts when
driving or riding in a motor vehi-
cle.
• If the vehicle or pre-tensioner
seat belt must be discarded, con-
tact an authorized HYUNDAI deal-
er.

How does the air bag system
operate
• Air bags are activated (able to inflate if
necessary) only when the engine
start/stop button is turned to the ON or
START position.
• Air bags inflate instantly in the event of
a serious frontal collision or side colli-
sion in order to help protect the occu-
pants 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 col-
lision and its direction. These two fac-
tors determine whether the sensors
produce an electronic deployment/
inflation signal.
• Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. The determining factors are
not limited to those mentioned above.
• The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to see
the air bags inflate during an accident.It is much more likely that you will sim-
ply see the deflated air bags hanging
out of their storage compartments after
the collision.
• In order to help provide protection in a
severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to inflate the air
bag between the occupant and the
vehicle structures before the occupant
impacts those structures. This speed of
inflation reduces the risk of serious or
life-threatening injuries in a severe col-
lision and is thus a necessary part of air
bag design.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bones
because the inflation speed also caus-
es the air bags to expand with a great
deal of force.
• There are even circumstances
under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close to
the steering wheel.
WARNING
• To avoid severe personal injury
or death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 250 mm (10 inches)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
• Air bags inflate instantly in the
event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
a proper position.
• Air bag inflation may cause
injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

Air bag warning light
The purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the warning light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
• The light does not turn on briefly when
you turn the engine start/stop button to
the ON position.
• The light stays on after illuminating for
approximately 6 seconds.
• The light comes on while the vehicle is
in motion.
• The light blinks when the engine
start/stop button is in ON position.
SRS components and functions
The SRS consists of the following com-
ponents:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side impact air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM)
8. Front impact sensors
9. Side impact sensors
10. Driver’s knee air bag module
11. Driver’s and front passenger’s seat
belt buckle sensors.The SRSCM continually monitors all
SRS components while the engine
start/stop button is ON to determine if a
crash impact is severe enough to require
air bag deployment or pre-tensioner seat
belt deployment.
The SRS air bag warning light " " on
the instrument panel will illuminate for
about 6 seconds after the engine
start/stop button is turned to the ON posi-
tion, after which the SRS air bag warning
light " " should go out.
W7-147OVI039100L
WARNING
If any of the following conditions
occurs, this indicates a malfunction
of the SRS. Have an authorized
HYUNDAI dealer inspect the air bag
system as soon as possible.
• The light does not turn on briefly
when you turn the engine
start/stop button to the ON posi-
tion.
• The light stays on after illuminat-
ing for approximately 6 seconds.
• The light comes on while the
vehicle is in motion.
• The light blinks when the engine
start/stop button is in ON posi-
tion.

Safety features of your vehicle
Driver's and passenger's front air
bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) System
and the lap/shoulder belts at both the
driver and passenger seating positions.The indications of the system's presence
are the letters "SRS AIR BAG"
embossed on the air bag pad cover in the
steering wheel and/or on the cover of the
driver's side knee bolster located below
the steering wheel and the passenger's
side front panel pad above the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel , in the knee bolster below
the steering wheel column and the pas-
senger's side front panel above the glove
box.
The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt system alone in
case of a frontal impact of sufficient
severity. The SRS uses sensors to gath-
er information about the driver's seat
position, the driver's and front passen-
ger's seat belt usage and impact severi-
ty.

The seat belt buckle sensors (if
equipped) determine if the driver and
front passenger's seat belts are fas-
tened. These sensors provide the ability
to control the SRS deployment based on
whether or not the seat belts are fas-
tened, and how severe the impact is.(Continued)
• ABC – Always Buckle Children in
the back seat. It is the safest place
for children of any age to ride.
• Front and side impact air bags
can injure occupants improperly
positioned.
• Move your seat as far back as
practical from the front air bags,
while still maintaining control of
the vehicle.
• You and your passengers should
never sit or lean unnecessarily
close to the air bags. Improperly
positioned drivers and passen-
gers can be severely injured by
inflating air bags.
• Never lean against the door or
center console – always sit in an
upright position.
• No objects should be placed over
or near the air bag modules on
the steering wheel, instrument
panel, driver’s side knee bolster,
and the front passenger's panel
above the glove box, because any
such object could cause harm if
the vehicle is in a crash severe
enough to cause the air bags to
deploy.
(Continued)(Continued)
• Do not tamper with or disconnect
SRS wiring or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental deployment of the air bags
or by rendering the SRS inopera-
tive.
• If the SRS air bag warning light
“ ”remains illuminated while
the vehicle is being driven, have
an authorized HYUNDAI dealer
inspect the air bag system as
soon as possible.
• Air bags can only be used once –
have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
• The SRS is designed to deploy
the front air bags only when an
impact is sufficiently severe and
when the impact angle is less
than 30° from the forward longitu-
dinal axis of the vehicle.
Additionally, the air bags will only
deploy once. Seat belts must be
worn at all times.
(Continued)
WARNING
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with con-
siderable force and in the blink of
an eye. Seat belts help keep occu-
pants in proper position to obtain
maximum benefit from the air bag.
Even with air bags, improperly belt-
ed and unbelted occupants can be
severely injured when the air bag
inflates. Always follow the precau-
tions about seat belts, air bags and
occupant safety contained in this
manual.
To reduce the chance of serious or
fatal injuries and receive the maxi-
mum safety benefit from your
restraint system:
• Never place a child in any child or
booster seat in the front seat.
