B230G04Y-AATChild Restraint System Installation on
Rear Seats
B230G01NF-B
On outboard rear seats
B235G02NF-A
On rear seat center positionTo install a child restraint system in the rear
seats, extend the shoulder/lap belt entirely from
its retractor until a "click" is felt. This will engage
the seat belt retractor automatic locking feature,
which allows the seat belt to retract but not
extend. Install the child restraint system, buckle
the seat belt and allow the seat belt to take up
any slack. Make sure that the lap portion of the
belt is tight around the child restraint system and
the shoulder portion of the belt is positioned so
that it cannot interfere with the child's head or
neck. Also, double check to be sure that the
retractor has engaged the Automatic Locking
feature by trying to extend webbing out of the
retractor. If the retractor is in the Automatic
Locking mode, the belt will be locked. After
installation of the child restraint system, try to
move it in all directions to be sure the child
restraint system is securely installed. If you need
to tighten the belt, pull more webbing toward the
retractor. When you unbuckle the seat belt and
allow it to retract, the retractor will automatically
revert back to its normal seated passenger
Emergency Locking usage condition.
!
WARNING:
o If the retractor is not in the Automatic
Locking mode, the child restraint can
move when your vehicle turns or stops
suddenly. A child can be seriously in-
jured or killed if the child restraint is not
properly anchored to the car, including
setting the retractor to the Automatic
Locking mode.
o Do not install any child restraint system
in the front passenger 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. Therefore, only
use a child restraint system in the rear
seat of your vehicle.NOTE:o Before installing the child restraint sys-
tem in any seating position, read the
instructions supplied by the child re-
straint system manufacturer.
o If the seat belt does not operate as de-
scribed, have the system checked imme-
diately by your authorized Hyundai dealer.

!
WARNING:
o Do not modify or replace the front pas-
senger seat. Don't place anything on or
attach anything such as a blanket or
after market seat heater to the front
passenger seat. This can adversely af-
fect the occupant classification system.
o Do not sit on sharp objects such as tools
when occupying the front passenger
seat. This can adversely affect the occu-
pant classification system.
o Do not use accessory seat covers on the
front seats.
o Accident statistics show that children
are safer if they are restrained in the rear,
as opposed to the front seat. It is recom-
mended that child restraints be secured
in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding
in a forward-facing child seat and an
older child riding in a booster seat.
o Airbags can only be used once – have an
authorized Hyundai dealer replace the
airbag immediately after deployment.
!
WARNING:
o A smaller-stature adult who is not seated
correctly (for example: seat excessively
reclined, leaning on the center console,
or hips shifted forward in the seat) can
cause a condition where the advanced
frontal airbag system senses less weight
than if the occupant were seated prop-
erly (sitting upright with the seatback in
an upright position, centered on the seat
cushion with their seat belt on, legs
comfortably extended and their feet on
the floor). This condition can result in an
adult potentially being misclassified and
illumination of the "PASSENGER AIR
BAG OFF" indicator.
B990B05Y-AATSide Impact Airbag (If installed)Your Hyundai is equipped with a side impact
airbag in each front seat. The purpose of the
airbag is to provide the vehicle's driver and/or
the front passenger with additional protection
than that offered by the seat belt alone. The side
impact airbags are designed to deploy only
during certain side-impact collisions, depend-
ing on the crash severity, angle, speed and point
of impact. The side impact airbags are not
designed to deploy in all side impact situations.

Integrated HomeLink
® Wireless Control
System
The HomeLink
® Wireless Control System pro-
vides a convenient way to replace up to three
hand-held radio-frequency (RF) transmitters
with a single built-in device. This innovative
feature will learn the radio frequency codes of
most current transmitters to operate devices
such as gate operators, garage door openers,
entry door locks, security systems, even home
lighting. Both standard and rolling code-equipped
transmitters can be programmed by following
the outlined procedures. Additional HomeLink
®
information can be found at: www.homelink.com
or by calling 1-800-355-3515.
CAUTION:
Before programming HomeLink
® to a ga-
rage door opener or gate operator, make
sure that people and objects are out of the
way of the device to prevent potential harm
or damage. Do not use HomeLink® with any
garage door opener that lacks the safety
stop and reverse features as required by
U.S. federal safety standards (this includes
any garage door opener model manufac-
tured before April 1, 1982). A garage door
that cannot detect an object - signaling the
door to stop and reverse - does not meet
current U.S. federal safety standards. Using
a garage door opener without these fea-
tures increases the risk of serious injury or
death.Programming HomeLink
®
NOTE:o When programming a garage door
opener, it is advised to park the vehicle
outside of the garage.
o It is recommended that a new battery be
placed in the hand-held transmitter of
the device being programmed to
HomeLink
® for quicker training and ac-
curate transmission of the radio-fre-
quency signal.
o Some vehicles may require the ignition
switch to be turned to the second (or
"accessories") position for program-
ming and/or operation of HomeLink.
o In the event that there are still program-
ming difficulties or questions after fol-
lowing the programming steps listed
below, contact HomeLink
® at:
www.homelink.com or 1-800-355-3515.
Retain the original transmitter of the RF device
you are programming for use in other vehicles
as well as for future HomeLink
® programming.
It is also suggested that upon the sale of the
vehicle, the programmed HomeLink
® buttons
be erased for security purposes.

C090E01NF-GATo D (Drive):Use for normal driving. The transaxle will auto-
matically shift through a four/five gear sequence.C090D02A-AATo N (Neutral):In the "N" position, the transaxle is in neutral,
which means that no gears are engaged. The
engine can be started with the shift lever in "N"
position, although this is not recommended
except if the engine stalls while the car is
moving.C090C01A-AATo R (Reverse):Use for backing up the vehicle. Bring the car to
a complete stop before shifting the selector
lever to "R" position.
CAUTION:
o In sports mode, the driver must execute
upward shifts in accordance with pre-
vailing road conditions, taking care to
keep the engine speed below the red
zone.
o For engine protection, upward shifts are
made automatically when the engine
rpm reaches the red zone.
o By rapidly moving the selector lever
backwards (-) twice it is possible to skip
one gear, i.e., 3rd to 1st, 4th to 2nd or 5th
to 3rd. Since sudden engine braking
and/or rapid acceleration can cause a
loss of traction, however, downshifts
must be made carefully in accordance
with the vehicle's speed.
