WARNING
When returning the rear seatback 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 seatback. In an accident
or sudden stop, an unlocked seatback
could allow cargo to move forward with
great force and enter the passenger
compartment, which could result in
serious injury or death.
WARNING
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 vehicle is off, the shift
button 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 button
is inadvertently moved to another
position.
Armrest
ODN8039018
The armrest is located in the center of
the rear seat. Pull the armrest down from
the seatback to use it.
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.
WARNING
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 passengers BEFORE
starting the vehicle.
• NEVER let anyone ride in a seat
with the head restraints removed or
reversed.

Seat BeltS
This section describes how to use the
seat belts properly. It also describes
some of the things to avoid when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
but they are not a substitute. Most states
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts:
• ALWAYS properly restrain children
under age 13 in the rear seats.
• 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
possible 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 shoulder
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.
• Do not use a seat belt if the webbing
or hardware is damaged. •
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 resulting 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.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace:
• Frayed, contaminated, or damaged
webbing
• Damaged hardware
• The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent

Children Always in the Rear
WARNING
Always properly restrain children in the
rear seats of the vehicle.
Children of all ages are safer when
restrained in the rear seat. A child riding
in the front passenger seat can be
forcefully struck by an inflating air bag
resulting in SERIOUS INJURY or DEATH.
Children under age 13 must always
ride in the rear seats and must always
be properly restrained to minimize the
risk of injury in an accident, sudden
stop or sudden maneuver. According
to accident statistics, children 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 specific 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 commercially available
child restraint system that meets the
requirements of the Federal Motor
Vehicle Safety Standards (FMVSS 213).
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 system in the rear seats of
the vehicle.
Child restraint system (CRS)
Infants and younger children must be
restrained in an appropriate rear-facing
or forward-facing CRS that has first
been properly secured to the rear seat
of the vehicle. Read and comply with
the instructions for installation and use
provided by the manufacturer of the
child restraint.
WARNING
An improperly secured child restraint
can increase the risk of SERIOUS
INJURY or DEATH in an accident. Always
take the following precautions when
using a child restraint system:
• NEVER install a child or infant
restraint in the front passenger’s
seat.
• Always properly secure the child
restraint to a rear seat of the vehicle.
• Always follow the child restraint
system manufacturer’s instructions
for installation and use.
• Always properly restrain your child in
the child restraint.
• If the vehicle head restraint prevents
proper installation of a child seat
(as described in the child restraint
system manual), the head restraint of
the respective seating position shall
be readjusted or entirely removed.
• Do not use an infant carrier or a
child safety seat that “hooks” over
a seatback, it may not provide
adequate protection in an accident.
• After an accident, have a HYUNDAI
dealer check the child restraint
system, seat belts, tether anchors
and lower anchors.

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
snugly 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)
WARNING
Before installing your child restraint
system always:
• Read and follow the instructions
provided by the manufacturer of the
child restraint.
• Read and follow the instructions
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 head restraint prevents
proper installation of a child seat as
described in the child seat system
manual, the head restraint of the
respective seating position shall be
readjusted or entirely removed.

3. Pull the shoulder portion of the
seat belt all the way out. When the
shoulder portion of the seat belt
is fully extended, it will shift the
retractor to the “Automatic Locking”
(child restraint) mode.
OLF034075
4. Slowly allow the shoulder portion of the seat belt to retract and listen for
an audible “clicking” or “ratcheting”
sound. This indicates that the retractor
is in the “Automatic Locking” mode.
If no distinct sound is heard, repeat
steps 3 and 4. 5.

R
emove as much slack from the belt
as possible by pushing down on the
child restraint system while feeding
the shoulder belt back into the
retractor.
6.
Push and pull on the child r
estraint
system to confirm that the seat belt
is holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7.
Double check tha
t the retractor is in
the “Automatic Locking” mode by
attempting to pull more of the seat
belt out of the retractor. If you cannot,
the retractor is in the “Automatic
Locking” mode.
If your CRS (child restraint system)
manufacturer instructs or recommends
you to use a tether anchor with the lap/
shoulder belt, refer to the previous pages
for more information.
Information
When the seat belt is allowed to retract to
its fully stowed position, the retractor will
automatically switch from the “Automatic
Locking” mode to the emergency lock
mode for normal adult usage.
WARNING
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
injured or killed if the child restraint
is not properly anchored in the car,
including manually pulling the seat belt
all the way out to shift the rectractor to
the “Automatic Locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully.

• When cleaning underneath the
vehicle, pay particular attention to the
components under the fenders and
other areas that are hidden from view.
Do a thorough job; just dampening
the accumulated mud rather than
washing it away will accelerate
corrosion rather than prevent it. Water
under high pressure and steam are
particularly effective in removing
accumulated mud and corrosive
materials.
• When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.
Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This creates
a favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered with
snow, ice or mud. Even a heated garage
can contribute to corrosion unless it is
well ventilated so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish should
be covered with “touch-up” paint as
soon as possible to reduce the possibility
of corrosion. If bare metal is showing
through, the attention of a qualified body
and paint shop is recommended.
Bird droppings are highly corrosive and
may damage painted surfaces in just a
few hours. Always remove bird droppings
as soon as possible.Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from
contacting the interior parts because
they may cause damage or discoloration.
If they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to clean
vinyl.
NOTICE
• Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
• When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or acid/
alkaline detergents, the color of the
leather may fade or the surface may
get stripped off.
Cleaning the upholstery and interior
trim
Vinyl (if equipped)
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl surfaces with a vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from
fabric with a whisk broom or vacuum
cleaner. Clean with a mild soap solution
recommended for upholstery or carpets.
Remove fresh spots immediately with
a fabric spot cleaner. If fresh spots do
not receive immediate attention, the
fabric can be stained and its color can be
affected. Also, its fire-resistant properties
can be reduced if the material is not
properly maintained.

Maintenance

NOTICE
Using anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.
Leather (if equipped)
• Features of seat leather
- L

eather is made from the outer skin
of an animal, which goes through a
special process to be available for
use. Since it is a natural product,
each part differs in thickness or

from usage. It is not a fault of the
products.
CAUTION
• Wrinkles or abrasions which appear
naturally from usage are not covered
by warranty.
• Belts with metallic accessories,
zippers or keys inside the back
pocket may damage the seat fabric.
• Make sure not to wet the seat. It may
change the nature of natural leather.
• Jeans or clothes which could bleach
may contaminate the surface of the
