Installing a Child Restraint
System (CRS)After selecting a proper Child Restraint
System for your child and checking
that the Child Restraint System fits
properly on the seating position, there
are three general steps for a proper
installation:
•Properly secure the Child Restraint
System to the vehicle.
All Child
Restraint Systems must be secured
to the vehicle with the lap belt or lap
part of a lap/shoulder belt or with
the ISOFIX top-tether and/or ISOFIX
anchorage and/or with the support
leg.
•Make sure the Child Restraint
System is firmly secured.After
installing a Child Restraint System
to the vehicle, push and pull the
seat forward and from side-to-side
to verify that it is securely attached
to the seat. A Child Restraint
System secured with a seat belt
should be installed as firmly as
possible. However, some side-to-
side movement can be expected.When installing a Child Restraint
System, adjust the vehicle seat and
seatback (up and down, forward and
rearward) so that your child fits in
the Child Restraint System in a con-
fortable manner.
•Secure the child in the Child
Restraint System.Make sure the
child is properly strapped in the
Child Restraint System according
to the Child Restraint System man-
ufacturer’s instructions. Before installing your Child
Restraint System always:
Read and follow the instructions
provided by the manufacturer of
the Child Restraint System.
Failure to follow all warnings
and instructions could increase
the risk of the SERIOUS INJURY
or DEATH if an accident occurs.
WARNING
If the vehicle headrest prevents
proper installation of a Child
Restraint System, the headrest
of the respective seating posi-
tion shall be readjusted or
entirely removed.
WARNING
A Child Restraint System in a
closed vehicle can become very
hot. To prevent burns, check the
seating surface and buckles
before placing your child in the
Child Restraint System.

Side air bags (if equipped)
Your vehicle is equipped with a side air
bag in each front seat. The purpose of
the air bag is to provide the vehicle’s
driver and the front passenger with
additional protection than that offered
by the seat belt alone.The side air bags are designed to
deploy during certain side impact col-
lisions, depending on the crash
severity, angle, speed and point of
impact.
The side air bags are not designed to
deploy in all side impact situations.
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 positions,
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.
•Do not hang other objects
except clothes. In an accident
it may cause vehicle damage
or personal injury especially
when air bag 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.

How does the air bags system
operate?
The SRS consists of the following
components:
(1) Driver's front air bag module/
Driver’s knee air bag module
(2) Passenger's front air bag module
(3) Side air bag modules/
Side impact sensors
(4) Curtain air bag modules
(5) Front retractor pre-tensioner/
Rear retractor pre-tensioner
assemblies (if equipped)
(6) Air bag warning light
(7) SRS control module (SRSCM)(8) Front impact sensors
(9) Side pressure sensors
(10) Passenger’s front air bag
ON/OFF indicator
(front passenger's seat only)
(11) Passenger’s front air bag
ON/OFF switch
The SRSCM continually monitors all
SRS components while the ignition
switch is ON to determine if a crash
impact is severe enough to require
air bag deployment or pre-tensioner
seat belt deployment.

•Do not place any objects over
the air bag. Also, do not attach
any objects around the area the
air bag inflates such as the
door, side door glass, front and
rear pillar, roof side rail.
•Do not hang other objects
except clothes, especially hard
or breakable objects. In an
accident, it may cause vehicle
damage or personal injury.
•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.
•Do not open or repair the side
curtain air bags.

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 electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system.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,
at the time and with the force needed.
The front air bags help protect the driv-
er 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 protection in the
event of a side impact by supporting
the side upper body area.
• Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.
• Air bags inflate in the event of certain
frontal or side collisions to help pro-
tect 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 collision and its direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic deployment/inflation signal.
Safety system of your vehicle
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 conditions
occur, your SRS is malfunction-
ing:
•The light does not turn on for
approximately six seconds
when the ignition switch 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.
We recommend that an author-
ized HYUNDAI dealer inspect the
SRS as soon as possible if any
of these conditions occur.

• Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles
or objects which your vehicle
impacts during a 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 acci-
dent. It is much more likely that you
will simply see the deflated air bags
hanging out of their storage com-
partments after the collision.• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which 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 and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises
and broken bones because the
inflation speed also causes the air
bags to expand with a great deal of
force.
• There are even circumstances
under which contact with the air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.You can take steps to reduce the risk
of being injured by an inflating air
bag. The greatest risk is sitting too
close to the air bag. An air bag needs
space to inflate. It is recommended
that drivers sit as far as possible
between the center of the steering
wheel and the chest while still main-
taining control of the vehicle.

Information
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 sur-
faces may damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.

•When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
•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.
(Continued)
(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.
