Introduction
Gasoline containing alcohol andmethanol
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 useof:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
Use of MTBE
HYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
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 willdamage the engine control sys-
tem’s oxygen sensor and affectemission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consult
an authorized HYUNDAI dealer for details.)
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuelsystem and any performance prob-lems that are caused by the use of
fuels containing methanol or fuels containing MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (Oxygen Content 2.7% weight.)
CAUTION
Never use gasohol which containsmethanol. 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 thefront passenger's seat.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the switches in theOFF position.

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.

✽✽NOTICE
 Both the driver's and front passen- ger's pre-tensioner seat belts may be
activated in certain frontal collisions.
The pre-tensioners will not be activat-
ed if the seat belts are not being worn
at the time of the collision.
 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 oper-
ating conditions and are not haz-
ardous.
 Although it is harmless, the fine dust
may cause skin irritation and should
not be breathed for prolonged peri-
ods. Wash all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were activat-
ed. ✽✽
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 nomalfunction of the SRS air bag. Ifthe SRS air bag warning light does not illuminate when the ignition
switch is turned to ON, or if itremains illuminated after illuminat-ing for approximately 6 seconds, orif it illuminates while the vehicle is
being driven, have an authorizedHYUNDAI 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.

How does the air bag system operate
Air bags are activated (able to inflate ifnecessary) 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 vehiclespeed, 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 afterthe collision.
In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air baginflation is a consequence of the
extremely short time in which a collisionoccurs 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 airbag design.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bonesbecause 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 tothe 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 whenyou 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 forabout 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.

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.

Driver's and passenger's front air
bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) Systemand 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 incase 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.

Safety features of your vehicle
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 inthe back seat. It is the safest place
for children of any age to ride.
Front and side impact air bags can injure occupants improperlypositioned.
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 disconnectSRS 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 andwhen 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 yourrestraint system:
Never place a child in any child or booster seat in the front seat.

Safety features of your vehicle
(Continued)
Use of seat covers could reduceor prevent the effectiveness of the system.
Do not install any accessories on the side or near the side impact
air bag.
Do not place any objects over the air bag or between the air bag
and yourself.
Do not place any objects (an umbrella, bag, etc.) between the
door and the seat. Such objects
may become dangerous projec-
tiles and cause injury if the sup-
plemental side impact air baginflates.
To prevent unexpected deploy- ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switchis on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags.Your vehicle is equipped with a side impact air bag in each front and outboard
rear seat. The purpose of the air bag is to
provide the vehicle's driver and/or thefront and outboard rear passengers with
additional protection than that offered by
the seat belt alone.
The side impact air bags are designedto deploy during certain side-impact
collisions, depending on the crash
severity, angle, speed and point ofimpact.
The side impact air bags are not designed to deploy in all side impact.
WARNING
The side impact air bag is sup- plemental to the driver’s and the
passengers seat belt systems
and is not a substitute for them.
Therefore your seat belts must be
worn at all times while the vehicle
is in motion. The air bags deploy
only in certain side impact condi-
tions severe enough to cause
significant injury to the vehicleoccupants.
For best protection from the side impact air bag system and to
avoid being injured by the
deploying side impact air bag,
both front and all rear (ifequipped) seat occupants shouldsit in an upright position with the
seat belt properly fastened. Thedriver's hands should be placedon the steering wheel at the 9:00
and 3:00 positions. The passen-
ger’ arms and hands should beplaced on their laps.
Do not use any accessory seat covers.

Why didn’t my air bag go off in a collision? (Inflation and non-infla-
tion conditions of the air bag)
There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.
