ILLUMINATED IGNITION SWITCHWhenever either front door is opened, the igni-
tion switch will be illuminated for your conve-
nience, provided the ignition switch is not in the
"ON" position.
The light will go off approximately 10 seconds
after closing the door or when the ignition switch
is turned on.
WARNING:
o Unlocked doors can be dangerous. Be-
fore you drive away (especially if there
are children in the car), be sure that all the
doors are securely closed and locked so
that the doors cannot be opened from
the inside. This helps ensure that the
doors will not be opened accidentally.
Also, when combined with the proper
use of seat belts, locking the doors helps
keep occupants from being ejected from
the car in case of an accident.
o Before opening the door, always look for
and avoid oncoming traffic.
B030B01NF-GATRecord Your Key NumberA code number is attached on the number tag
that came with the keys to your Hyundai. This
key number tag should not be left with the keys
but kept in a safe place, not in the vehicle. The
key number should also be recorded in a place
where it can be found in an emergency.
If you need additional keys, or if you should lose
your keys, your authorized Hyundai dealer can
make new keys if you can supply the key
number.

SEAT BELTSB150B03Y-AATInfant or Small ChildAll 50 states have child restraint laws. You
should be aware of the specific requirements in
your state. Child and/or infant safety seats must
be properly placed and installed in the rear seat.
Information about the use of these restraints
begins on page 1-28.
!
B150A01S-AATSEAT BELT PRECAUTIONS
WARNING:All occupants of the vehicle must wear their
seat belts at all times. Note that this vehicle
is equipped with a Supplemental Restraint
(Airbag) System as discussed beginning
on page 1-36. The seat belts must be used
in conjunction with the supplemental
airbag system. State laws require that some
or all occupants of the vehicle use seat
belts. The possibility of increased injury or
severity of injury in an accident will be
increased if this elementary safety precau-
tion is not observed. In addition, follow the
other instructions provided in this section.
!
WARNING:
Every person in your vehicle needs to be
properly restrained at all times, including
infants and children. In a collision, an unre-
strained child can become a "missile" in-
side the car. The force required to hold a
child on your lap could be so great that you
could not hold the child. Any child riding in
the vehicle should always be in a proper
restraint in the rear seat of the vehicle.NOTE:Small children are best protected from in-
jury in an accident when properly restrained
in the rear seat by a child restraint system
that meets the requirements of the Federal
Motor Vehicle Safety Standards. Before
buying any child restraint system, make
sure that it has a label certifying that it
meets Federal Motor Vehicle Safety Stan-
dard 213. The restraint must be appropriate
for your child's height and weight. Check
the label on the child restraint for this
information. See page 1-28.
B150C02A-AATLarger ChildrenChildren who are too large for child restraint
systems should always occupy the rear seat
and use the available lap/shoulder belts. The lap
portion should be fastened snug on the hips and
as low as possible. Check belt fit periodically. A
child's squirming could put the belt out of posi-
tion. Children are afforded the most safety in the
event of an accident when they are restrained
by a proper restraint system in the rear seat. If
a larger child (over age 13) must be seated in
the front seat, the child should be securely
restrained by the available lap/shoulder belt and
the seat should be placed in the rearmost
position. Children under the age of 13 should be
restrained securely in the rear seat. NEVER
place a child under the age of 13 in the front seat.
NEVER place a rear facing child seat in the front
seat of a vehicle.B150D01A-AATPregnant WomenThe use of a seat belt is recommended for
pregnant women to lessen the chance of injury
in an accident. When a seat belt is used, the lap
belt portion should be placed as low and snugly
as possible on the hips, not across the abdo-
men. For specific recommendations, consult a
physician.

B190A01NF-AATSEAT BELTS-Front Passenger and Rear
Seat 3-Point System with Combination
Locking Retractor
To Fasten Your BeltCombination retractor type seat belts are in-
stalled in the rear seat positions to help accom-
modate the installation of child restraint systems.
Although a combination retractor is also installed
in the front passenger seat position, Hyundai
strongly recommends that children always be
seated in the rear seat. NEVER place any infant
restraint system in the front seat of the vehicle.
This type of seat belt combines the features of
both an emergency locking retractor seat belt
and an automatic locking retractor seat belt. To
fasten your seat belt, pull it out of the retractor
and insert the metal tab into the buckle. There
will be an audible "click" when the tab locks into
the buckle. When not securing a child restraint,
the seat belt operates in the same way as the
driver's seat belt (Emergency Locking Retrac-
tor Type). It automatically adjusts to the proper
length only after the lap belt portion of the seat
belt is adjusted manually so that it fits snugly
around your hips. When the seat belt is fully
extended from the retractor to allow the instal-
lation of a child restraint system, the seat belt
operation changes to allow the belt to retract, but
not to extend (Automatic Locking Retractor
Type). See page 1-32.
B180A01NF-AATSEAT BELT-Driver's 3-Point System with
Emergency Locking Retractor
To Fasten Your BeltTo fasten your seat belt, pull it out of the retractor
and insert the metal tab into the buckle. There
will be an audible "click" when the tab locks into
the buckle.
The seat belt automatically adjusts to the proper
length only after the lap belt portion is adjusted
manually so that it fits snugly around your hips.
If you lean forward in a slow, easy motion, the
belt will extend and let you move around. If there
is a sudden stop or impact, however, the belt will
lock into position. It will also lock if you try to lean
forward too quickly.
B180A01NF
NOTE:If the driver's seat belt is not fastened when
the ignition key is turned from the "OFF"
position to the "ON" or "START" position,
the seat belt warning light will blink and the
warning chime will sound for approximately
six seconds to remind the driver to fasten
the driver's seat belt.

WARNING:
o A child restraint system must be placed
in the rear seat. Never install a child or
infant seat on the front passenger's seat.
Should an accident occur and cause the
passenger side airbag to deploy, it could
severely injure or kill an infant or child
seated in an infant or child seat. Thus
only use a child restraint in the rear seat
of your vehicle.
o A safety belt or child restraint system
can become very hot if it is left in a closed
vehicle on a sunny day, even if the out-
side temperature does not feel hot. Be
sure to check the seat cover and buckles
before placing a child there.
o When the child restraint system is not in
use, store it in the trunk or fasten it with
a safety belt so that it will not be thrown
forward in the case of a sudden stop or
an accident.
o Children who are too large to be in a child
restraint should sit in the rear seat and be
restrained with the available lap/shoul-
der belts. Never allow children to ride in
the front passenger seat.
B220C02A-GATTo Release the Seat BeltWhen you want to release the seat belt, press
the button in the locking buckle.
!
WARNING:
When fastening the outboard seat belts or
the center seat belt, make sure they are
inserted into the correct buckles to obtain
maximum protection from the seat belt
system and assure proper operation.
CHILD RESTRAINT SYSTEMB230A03Y-AATChildren riding in the car should sit in the rear
seat and must always be properly restrained to
minimize the risk of injury in an accident, sudden
stop or sudden maneuver. According to acci-
dent statistics provided by the National High-
way Traffic Safety Administration (NHTSA),
children are safer when properly restrained in
the rear seats than in the front seat. Larger
children not in a child restraint should use one
of the seat belts provided.
All 50 states have child restraint laws. You
should be aware of the specific requirements in
your state. Child and/or infant safety seats must
be properly placed and installed in the rear seat.
You must use a commercially available child
restraint system that meets the requirements of
the Federal Motor Vehicle Safety Standards
(FMVSS).
Children could be injured or killed in a crash if
their restraints are not properly secured. For
small children and babies, a child seat or infant
seat must be used. Before buying a particular
child restraint system, make sure it fits your car
seat and seat belts, and fits your child. Follow
all the instructions provided by the manufac-
turer when installing the child restraint system.

WARNING:
o Always make sure that the shoulder belt
portion of the lap/shoulder belt is posi-
tioned midway over the shoulder and
never across the neck or behind the
back. Moving the child closer toward the
seat belt buckle may help provide a good
shoulder belt fit. The lap belt portion of
the lap/shoulder belt must always be
positioned as low as possible on the
child's hips, and as snug as possible.
o If the seat belt will not properly fit the
child, Hyundai recommends the use of
an approved booster seat in the rear seat
in order to raise the child's seating height
so that the seat belt will properly fit the
child.
Before purchasing a booster seat, make
sure that it meets applicable Federal
Motor Vehicle Safety Standards (FMVSS)
and that it is satisfactory for use with this
vehicle.
o Never allow a child to stand up or kneel
on the seat.
o Never use an infant carrier or a child
safety seat that "hooks" over a seatback;
it may not provide adequate security in
an accident.
WARNING:
o Never allow a child to be held in a person's
arms while they are in a moving vehicle,
as this could result in serious injury to
the child in the event of an accident or a
sudden stop. Holding a child in a moving
vehicle does not provide the child with
any means of protection during an acci-
dent, even if the person holding the child
is wearing a seat belt.
!
B230B01NF-AATUsing a Child Restraint SystemFor small children and babies, the use of a child
seat or infant seat is required. This child seat or
infant seat should be of appropriate size for the
child and should be installed in accordance with
the manufacturer's instructions. It is further
required that the seat be placed in the vehicle's
rear seat. Your vehicle is provided with three
child restraint hook holders for installing the
child seat or infant seat.

the tether strap under the headrest and
between the headrest posts, otherwise route
the tether strap over the top of the seatback.
3. Connect the tether strap hook to the child
restraint hook holder and tighten to secure
the seat.
WARNING:
Do not mount more than one child restraint
to a single tether or to a child restraint lower
anchorage point. The improper increased
load may cause the anchorage points or
tether anchor to break, causing serious
injury or death.
2. Route the child restraint seat tether strap
over the seatback.

B230D03E-AATSecuring the Child Restraint Seat with
the "ISOFIX" systemSome child seat manufacturers make safety
seats that are labeled as ISOFIX or ISOFIX-
compatible child seats. These seats include two
rigid or webbing mounted attachments that
connect to two ISOFIX anchors at specific
seating positions in your vehicle. This type of
child seat eliminates the need to use seat belts
to attach the child seat for forward-facing child
seats.
ISOFIX anchors have been provided in your
vehicle. The ISOFIX anchors are located in the
left and right outboard rear seating positions.
Their locations are shown in the illustration.
There is no ISOFIX anchor provided for the
center rear seating position.
B230D01NF
The ISOFIX anchors are located between the
seatback and the seat cushion of the rear seat
left and right outboard seating positions.
!
WARNING:
o Do not install a child restraint seat at the
center of the rear seat using the vehicle's
ISOFIX anchors. The ISOFIX anchors are
only provided for the left and right out-
board rear seating positions. Do not
misuse the ISOFIX anchors by attempt-
ing to attach a child safety seat in the
middle of the rear seat position to the
ISOFIX anchors. In a crash, the child seat
ISOFIX attachments may not be strong
enough to secure the child restraint seat
properly in the center of the rear seat and
may break, causing serious injury or
death.
o Do not mount more than one child re-
straint to a single tether or to a child
restraint lower anchorage point. The
improper increased load may cause the
anchorage points or tether anchor to
break, causing serious injury or death.
o Attach the ISOFIX or ISOFIX-compatible
child seat only to the appropriate loca-
tions shown.
o Always follow the installation and use
instructions provided by the manufac-
turer of the child restraint.
