Reclining seatback
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.Seat belts must be snug against your
hips and chest to work properly.
When the seatback is reclined, the
shoulder belt cannot do its job
because it will not be snug against
your chest. Instead, it will be in front
of you. During an accident, you could
be thrown into the seat belt, causing
neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger's
hips will slide under the lap belt or
the passenger's neck will strike the
shoulder belt.
Seat cushion height
To change the height of the seat
cushion:
1. Pull the front portion of the control
switch up to raise or push down to
lower the front part of the seat
cushion. Pull the rear portion of the
control switch up to raise or push
down to lower the seat cushion.
2. Release the switch once the seat reaches the desired position.
Safety system of your vehicle
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.
Driver and passengers should
ALWAYS sit well back in their
seats, properly belted, and with
the seatbacks upright.

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

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.

Rear Seat Belt – Passenger’s 3-point system with convertiblelocking retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed in
the rear seat positions to help accom-
modate the installation of child
restraint systems. Although a convert-
ible retractor is also installed in the
front passenger seat position, NEVER
place any infant/child restraint system
in the front seat of the vehicle.
To fasten your seat belt:
Pull the seat belt out of the retractor
and insert the metal tab into the buck-
le. 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 Retractor Type). It automati-
cally adjusts to the proper length only
after the lap belt portion of the seat
belt is adjusted manually so that it fits
snugly across your hips.
(Continued)
Position one arm under the
shoulder belt and the other over
the belt, as shown in the illus-
tration.
Always position the shoulder
belt anchor into the locked
position at the appropriate
height.
Never position the shoulder
belt across your neck or face.
OLMB033025
Improperly positioned seat belts
may increase the risk of serious
injury in an accident. Take the fol-
lowing precautions when adjust-
ing the seat belt:
Position the lap portion of the
seat belt as low as possible
across your hips, not on your
waist, so that it fits snugly.

Seat Belt Anchor Pre-tensioner
The purpose of the Seat Belt Anchor
Pre-tensioner is to help the lap belt fit
tightly against the occupant's lower
body in certain frontal collisions. The
Seat Belt Anchor Pre-tensioner may
be activated in crashes where the
frontal collision is severe enough.Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioners become hot and
can burn you.
WARNING
Always wear your seat belt and
sit properly in your seat.
Do not use the seat belt if it is
loose or twisted. A loose or
twisted seat belt will not pro-
tect you properly in an acci-
dent.
Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
Always replace your pre-ten-
sioners after activation or an
accident.
NEVER inspect, service, repair
or replace the pre-tensioners
yourself. This must be done by
an authorized HYUNDAI dealer.
Do not hit the seat belt assem-
blies.
