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 seat-
back when the vehicle is moving.
Riding with a reclined seatback
increases your chance of serious
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.

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.

Children Always in the RearChildren under age 13 must always
ride in the rear seats and must
always be properly restrained to min-
imize the risk of injury in an accident,
sudden stop or sudden maneuver.
According to accident statistics, chil-
dren are safer when properly
restrained in the rear seats than in
the front seat.Even with air bags,
children can be seriously injured
or killed. Children too large for a
child restraint must use the seat belts
provided.
All 50 states have child restraint laws
which require children to travel in
approved child restraint devices. The
laws governing the age or
height/weight restrictions at which
seat belts can be used instead of
child restraints differs among states,
so you should be aware of the spe-
cific requirements in your state, and
where you are travelling. Child restraint systems must be
properly placed and installed in the
rear seat. You must use a commer-
cially available child restraint system
that meets the requirements of the
Federal Motor Vehicle Safety
Standards (FMVSS).
Child restraint systems are generally
designed to be secured in a vehicle
seat by lap belt portion of a
lap/shoulder belt, or by a LATCH sys-
tem in the rear seats of the vehicle.

Child restraint system types
There are three main types of child
restraint systems: rear-facing seats,
forward-facing seats, and booster
seats. They are classified according
to the child’s age, height and weight.
Rear-facing child seats
A rear-facing child seat provides
restraint with the seating surface
against the back of the child. The har-
ness system holds the child in place,
and in an accident, acts to keep the
child positioned in the seat and
reduce the stress to the neck and
spinal cord.
All children under age one must
always ride in a rear-facing infant child
restraint.
Convertible and 3-in-1 child seats typ-
ically have higher height and weight
limits for the rear-facing position,
allowing you to keep your child rear-
facing for a longer period of time.Continue to use a rear-facing child
seat for as long as your child will fit
within the height and weight limits
allowed by the child seat manufactur-
er. It’s the best way to keep them
safe. Once your child has outgrown
the rear-facing child restraint, your
child is ready for a forward-facing
child restraint with a harness.
OLMB033041NEVER install a child or infant
restraint in the front passen-
ger’s seat.
Placing a rear-facing child
restraint in the front seat can
result in SERIOUS INJURY or
DEATH if the child restraint is
struck by an inflating air bag.
WARNING

Forward-facing child restraints
A forward-facing child seat provides
restraint for the child’s body with a
harness. Keep children in a forward-
facing child seat with a harness until
they reach the top height or weight
limit allowed by your child restraint’s
manufacturer.
Once your child outgrows the forward-
facing child restraint, your child is
ready for a booster seat.
Booster seats
A booster seat is a restraint designed
to improve the fit of the vehicle’s seat
belt system. A booster seat positions
the seat belt so that it fits properly
over the lap of your child.
Keep your child in a booster seat until
they are big enough to sit in the seat
without a booster and still have the
seat belt fit properly. For a seat belt to
fit properly, the lap belt must lie snug-
ly across the upper thighs, not the
stomach. The shoulder belt should lie
snug across the shoulder and chest
and not across the neck or face.
Children under age 13 must always
ride in the rear seats and must always
be properly restrained to minimize the
risk of injury.
Installing a Child Restraint
System (CRS)
Before installing your child
restraint system always:
Read and follow the instruc-
tions provided by the manu-
facturer of the child restraint.
Read and follow the instruc-
tions regarding child restraint
systems in this manual.
Failure to follow all warnings
and instructions could increase
the risk of the SERIOUS INJURY
or DEATH if an accident occurs.
WARNING
If the vehicle headrest prevents
proper installation of a child
seat (as described in the child
seat system manual, the head-
rest of the respective seating
position shall be readjusted or
entirely removed.

Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving.A passenger who is not
wearing a seat belt during a crash or
emergency stop can be thrown
against the inside of the vehicle,
against other occupants, or be ejected
from the vehicle.
Do not use any accessories on seat
belts. Devices claiming to improve
occupant comfort or reposition the
seat belt can reduce the protection
provided by the seat belt and increase
the chance of serious injury in a crash
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
Do not place items under the front
seats. Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraint sys-
tem sensing components and wiring
harnesses.
Do not cause impact to the doors.
Impact to the doors when the Engine
Start/Stop button is in the ON position
may cause the air bags to inflate. Modifications to accommodate
disabilities.
If you require modifica-
tion to your vehicle to accommodate
a disability, contact the HYUNDAI
Customer Connect Center at 1-877-
378-8727.
Adding equipment to or modify- ing your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle’s frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle’s air bag system.
(Continued)
If components of the air bag
system must be discarded, or if
the vehicle must be scrapped,
certain safety precautions
must be observed. Consult an
authorized HYUNDAI dealer for
the necessary information.
Failure to follow these precau-
tions could increase the risk of
personal injury.

Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
