B150E01A-AATInjured Person
A seat belt should be used when an injured
person is being transported. When this is nec-
essary, you should consult a physician for
recommendations.
B150F01A-AAT
One Person Per Belt
Two people (including children) should never
attempt to use a single seat belt. This could
increase the severity of injuries in case of an
accident.
WARNING:Sitting in a reclined position or lying down
when your vehicle is in motion can be
dangerous. Even if you buckle up, your seat
belts can't do their job when you're re-
clined.
The shoulder belt can't do its job because
it won't be against your body.
Instead, it will be in front of you. In a crash
you could go into it with great force, receiv-
ing serious neck or other injuries.
The lap belt can't do its job either. In a crash
the belt could go up over your abdomen.
The belt forces would be applied there, not
at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright.
Then sit back in the seat and wear your seat
belt properly.
B150G02A-AATDo Not Lie Down
To reduce the chance of injuries in the event of
an accident, and to achieve maximum effective-
ness of the restraint system, all passengers
should be sitting up and the front seats should
be in an upright position when the car is moving.
A seat belt cannot provide proper protection if
the person is lying down in the rear seat or if the
front seat is in a reclined position.
B160A01A-AATCARE OF SEAT BELTSSeat belt systems should never be disassembled
or modified. In addition, care should be taken to
assure that seat belts and belt hardware are not
damaged by seat hinges, doors or other abuse.
WARNING:When you return the rear seatback to its
upright position after the rear seatback was
folded down, be careful not to damage the
seat belt webbing or buckle. Be sure that
the webbing or buckle does not get caught
or pinched in the rear seat.
B160B01A-AATPeriodic Inspection
It is recommended that all seat belts be in-
spected periodically for wear or damage of any
kind. Parts of the system that are damaged
should be replaced as soon as possible.
B160C01A-AATKeep Belts Clean and Dry
Seat belts should be kept clean and dry. If belts
become dirty, they can be cleaned by using a
mild soap solution and warm water. Bleach, dye,
strong detergents or abrasives should not be
used because they may damage and weaken
the fabric.

!WARNING:o When using the rear seat center belt, you
must lock all metal tabs and buckles. If
any metal tab or buckle is not locked, it
will increase the chance of injury in the
event of collision.
o Never unlock the metal tab (a) and the
buckle (b) with the following excep-
tions.
(1) In case of folding rear seatbacks
down.
(2) If transporting an object on the rear
seat may cause damage to the rear
seat center belt.o Lock the metal tab (a) and the buckle (b)
immediately after folding rear seatbacks
up.
o To disconnect the metal tab (a) from the
buckle (b) , insert a sharp-ended tool
into the groove located on the buckle
(b).

To Release the Seat Belt
When you want to release the seat belt, press
the button in the locking buckle.
WARNING:The rear seat center belt latching mecha-
nism is different from those for the out-
board rear seat shoulder belts. When fas-
tening the outboard rear seat shoulder belts
or the rear seat center belt, make sure they
are inserted into the correct buckles to
obtain maximum protection from the seat
belt system and assure proper operation.

B990A04Y-AATPASSENGER PRESENCE DETECTION
The passenger presence detection system
detects the presence of a passenger in the right
front seat. If no passenger is recognized on the
front passenger seat, the deployment of the
front passenger and/or side airbag and seat belt
pretensioner will be prevented.
This system is designed to prevent the replace-
ment of airbag components that deploy need-
lessly in an accident.
NOTE:Luggage or other cargo heavier than 33 lbs
(15 kg) should not be placed on the passen-
ger front seat. This can allow the deploy-
ment of the front passenger and/or side air
bag in the case of an accident.
WARNING:The Passenger Presence Detection system
is not intended to prevent airbag deploy-
ment while a child is in the front passen-
ger's seat. It is intended only as a means to
reduce unnecessary collision damage re-
pair expense by preventing airbag and seat
belt pretensioner deployment when the
right front passenger seat is unoccupied.
Deployment is still possible if only a few
pounds are placed upon the seat. There-
fore, children must not be transported inthe front seat. All children must be seated
in the rear seat and properly restrained with
the vehicle's restraint system or a child
restraint system appropriate for the child's
size and weight.
B990B03Y-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 air bags are not
designed to deploy in all side impact situations.
WARNING:o For best protection from the side impact
airbag system and to avoid being injured
by the deploying side impact airbag,
both front seat occupants should sit in
an upright position with the seat belt
properly fastened. The driver's hands
should be placed on the steering wheel
at the 9:00 and 3:00 o'clock positions.
The passenger's arms and hands should
be placed in their laps.
o Do not use any accessory seat covers.
o Use of seat covers could reduce or pre-
vent the effectiveness of the system.
o Do not install any accessories on the
side or near the side impact airbag.
o Do not use excessive force on the side of
the seat.
