NEVER ride with a reclined
seatback when the vehicle is
moving.
Riding with a reclined seatback
increases your chance of seri-
ous or fatal injuries in the event
of a collision or sudden stop.
Drivers and passengers should
ALWAYS sit well back in their
seats, properly belted, and with
the seatbacks upright.
WARNING

Safety system of your vehicle
Seatback pocket
The seatback pocket is provided on
the back of the front seatbacks.
Rear Seats
Folding the rear seat
The rear seatbacks can be folded to
facilitate carrying long items or to
increase the luggage capacity of the
vehicle.
OLF034022N
To prevent the Occupant
Classification System from mal-
functioning:
Do not hang onto the front pas-
senger's seatback.
WARNING
Never allow passengers to sit
on top of the folded down
seatback while the vehicle is
moving. This is not a proper
seating position and no seat
belts are available for use.
This could result in serious
injury or death in case of an
accident or sudden stop.
Objects carried on the folded
down seatback should not
extend higher than the top of
the front seatbacks. This
could allow cargo to slide for-
ward and cause injury or dam-
age during sudden stops.
WARNING
Do not put heavy or sharp
objects in the seatback pockets.
In an accident they could come
loose from the pocket and
injure occupants.
CAUTION

Safety system of your vehicle
Armrest
The armrest is located in the center
of the rear seat. Pull the armrest
down by using the strap from the
seatback to use it.
You will find cup holders on the cen-
ter armrest.
Do not place objects in the rear
seats, since they cannot be
properly secured and may hit
vehicle occupants in a collision
causing serious injury or death.
WARNING
Make sure the engine is off, the
shift lever is in P (Park), and the
parking brake is securely applied
whenever loading or unloading
cargo. Failure to take these steps
may allow the vehicle to move if
the shift lever is inadvertently
moved to another position.
WARNING
When returning the rear seat-
back from a folded to an upright
position, hold the seatback and
return it slowly. Ensure that the
seatback is completely locked
into its upright position by
pushing on the top of the seat-
back. In an accident or sudden
stop, the unlocked seatback
could allow cargo to move for-
ward with great force and enter
the passenger compartment,
which could result in serious
injury or death.

Head Restraints
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly
they are designed to help protect
passengers from whiplash and other
neck and spinal injuries during an
accident, especially in a rear impact
collision.
Be careful when loading
cargo through the rear pas-
senger seats to prevent dam-
age to the vehicle interior.
When cargo is loaded through
the rear passenger seats,
ensure the cargo is properly
secured to prevent it from
moving while driving.
Unsecured cargo in the pas-
senger compartment can
cause damage to the vehicle
or injury to it’s occupants.
CAUTION
To reduce the risk of serious
injury or death in an accident,
take the following precautions
when adjusting your head
restraints:
Always properly adjust the
head restraints for all passen-
gers BEFORE starting the
vehicle.
NEVER let anyone ride in a
seat with the head restraints
removed.(Continued)
(Continued)

Adjust the head restraints so
the middle of the head
restraints is at the same height
as the height of the top of the
eyes.
NEVER adjust the head
restraint position of the dri-
ver’s seat when the vehicle is
in motion.
Adjust the head restraint as
close to the passenger's head
as possible. Do not use a seat
cushion that holds the body
away from the seatback.
Make sure the head restraint
locks into position after adjust-
ing it.

This section describes how to use the
seat belts properly. It also describes
some of the things not to do when
using seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and
make sure all passengers have fas-
tened their seat belts before starting
any trip. Air bags are designed to
supplement the seat belt as an addi-
tional safety device, but they are not a
substitute. Most states require all
occupants of a vehicle to wear seat
belts.

Seat belts must be used by ALL
passengers whenever the vehi-
cle is moving. Take the following
precautions when adjusting and
wearing seat belts:
ALWAYS properly restrain
children under age 13 in the
rear seats.
(Continued)
WARNING
(Continued)
NEVER allow children to ride
in the front passenger seat. If
a child age 13 or older must be
seated in the front seat, move
the seat as far back as possi-
ble and properly restrain them
in the seat.
NEVER allow an infant or child
to be carried on an occupant’s
lap.
NEVER ride with the seatback
reclined when the vehicle is
moving.
Do not allow children to share
a seat or seat belt.
Do not wear the shoulder belt
under your arm or behind your
back.
Always wear both the shoul-
der portion and lap portion of
the lap/shoulder belt.
Do not use the seat belt if it is
twisted. A twisted seat belt
will not protect you properly
in an accident.(Continued)
(Continued)
Do not use a seat belt if the
webbing or hardware is dam-
aged.
Do not latch the seat belt into
the buckles of other seats.
NEVER unfasten the seat belt
while driving. This may cause
loss of vehicle control result-
ing in an accident.
Make sure there is nothing in
the buckle interfering with the
seat belt latch mechanism.
This may prevent the seat belt
from fastening securely.
No modifications or additions
should be made by the user
which will either prevent the
seat belt adjusting devices
from operating to remove
slack, or prevent the seat belt
assembly from being adjusted
to remove slack.

2-32
Safety system of your vehicle
If the shoulder belt portion slightly
touches the child's neck or face, try
placing the child closer to the center
of the vehicle. If the shoulder belt still
touches their face or neck they need
to be returned to an appropriate
booster seat in the rear seat.
Transporting an injured person
A seat belt should be used when an
injured person is being transported.
Consult a physician for specific rec-
ommendations.
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 acci-
dent.
Do not lie down
Sitting in a reclined position when
the vehicle is in motion can be dan-
gerous. Even when buckled up, the
protections of your restraint system
(seat belts and air bags) is greatly
reduced by reclining your seatback.
To reduce the chance of injuries in
the event of an accident and to
achieve the maximum effectiveness
of the restraint system, all passen-
gers should be sitting up and the
front and rear seats should be in an
upright position when the car is mov-
ing. A seat belt cannot provide proper
protection if the person is lying down
in the rear seat or if the front or rear
seats are in a reclined position.
NEVER ride with a reclined
seatback when the vehicle is
moving.
Riding with a reclined seatback
increases your chance of seri-
ous or fatal injuries in the event
of a collision or sudden stop.
Drivers and passengers should
always sit well back in their
seats, properly belted, and with
the seatbacks upright.
WARNING
Always make sure children
are wearing their seat belts
and that they are properly
adjusted before driving.
NEVER allow the shoulder
belt to contact the child's
neck or face.
Do not allow more than one
child to use a single seat belt.

Care of Seat Belts
Seat belt systems should never be
disassembled or modified. In addi-
tion, care should be taken to assure
that seat belts and belt hardware are
not damaged by seat hinges, doors
or other abuse.
Periodic inspection
All seat belts should be inspected
periodically for wear or damage of
any kind. Any damaged parts should
be replaced as soon as possible by
an authorized HYUNDAI dealer.
Keep 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 solu-
tion and warm water. Bleach, dye,
strong detergents or abrasives
should not be used because they
may damage and weaken the fabric.
When to replace seat belts
The entire seat belt assembly or
assemblies should be replaced if the
vehicle has been involved in an acci-
dent. This should be done even if no
damage is visible. Additional ques-
tions concerning seat belt operation
should be directed to an authorized
HYUNDAI dealer.
