FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded gasoline with an octane rating of RON
(Research Octane Number) 95 / AKI
(Antiknock Index) 91 or higher.
You may use unleaded gasoline with an octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle. (Do not use methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num‐ ber) 91 / AKI (Antiknock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain maximum performance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The useof leaded fuel is detrimental to thecatalytic converter and will damagethe engine control system’s oxygensensor and affect emission control.Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (We recom‐mend that you consult an authorizedKia dealer for details.)
WARNING
•Do not "top off" after the nozzleautomatically shuts off when re‐fueling.
•Always check that the fuel cap isinstalled securely to prevent fuelspillage in the event of an acci‐dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
signed to use leaded gasoline. When you are going to use leaded gasoline,
we recommend that you ask an au‐
thorized Kia dealer whether leaded gasoline in your vehicle is available or
not.
Octane Rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol), and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or in‐ stead of leaded or unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use gas‐
oline or gasohol containing any metha‐ nol. Either of these fuels may cause
drivability problems and damage to the
fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufac‐ turer’s warranty if they result from the

domen where the belt could crushthe fetus during an impact.
Injured person
A seat belt should be used when an in‐
jured person is being transported. When this is necessary, you should con‐
sult a physician for recommendations.
One person per belt
Two people (including children) should
never attempt to use a single seat belt.
This could increase the severity of inju‐ ries in case of an accident.
Do not lie down
To reduce the chance of injuries in the
event of an accident and to achieve
maximum effectiveness of the re‐
straint system, all passengers should
be sitting up and the front and rear seats should be in an upright position
when the vehicle is moving. A seat belt
cannot provide proper protection if the person is lying down in the rear seat or
if the front and rear seats are in a re‐
clined position.
WARNING
Riding with a reclined seatback in‐creases your chance of serious or fa‐tal injuries in the event of a collisionor sudden stop. The protection ofyour restraint system (seat beltsand air bags) is greatly reduced byreclining your seat. Seat belts mustbe secured against your hips andchest to work properly. The morethe seatback is reclined, the greaterthe chance an occupant's hips willslide under the lap belt causing seri‐ous internal injuries. Also, the shoul‐der belt may strike the occupant'sneck. Drivers and passengers shouldalways sit well back in their seats,properly belted, and with the seat‐backs upright.
Care of seat belts
Seat belt systems should never be dis‐
assembled or modified. In addition, care should be taken to assure that seat
belts and belt hardware are not dam‐
aged by seat hinges, doors or other abuse.
WARNING
When you return the rear seatbackto its upright position after the rearseatback has been folded down, becareful not to damage the seat beltwebbing or buckle. Be sure that thewebbing or buckle does not getcaught or pinched in the rear seat. Aseat belt with damaged webbing orbuckle could possibly fail during acollision or sudden stop, resulting inserious injury. If the webbing orbuckles are damaged, get them re‐placed immediately.
Periodic inspection
All seat belts should be inspected peri‐
odically for wear or damage of any
kind. Any damaged parts should be re‐ placed as soon as possible.
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 solution and warm water. Bleach, dye, strong
detergents or abrasives should not be
used because they may damage and weaken the fabric.

CHILD RESTRAINT SYSTEM (CRS)
Our recommendation: Children
always in the rear
WARNING
Always properly restrain children inthe vehicle. Children of all ages aresafer when riding in the rear seats.Never place a rearward-facing ChildRestraint System on the front pas‐senger seat, unless the air bag is de‐activated.
Children under age 13 should 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, chil‐ dren are safer when properly restrain‐
ed in the rear seats than in the front
seat. Children too large for a Child Re‐ straint System must use the seat belts
provided.
Most countries have regulations which
require children to travel in approved Child Restraint Systems. The laws governing the age or height/
weight restrictions at which seat belts
can be used instead of Child Restraint System differ among countries, so you
should be aware of the specific require‐
ments in your country, and where you are travelling.
Child Restraint Systems must be prop‐
erly installed in the vehicle seat. Always
use a commercially available Child Re‐ straint System that meets the require‐
ments of your country.
Child Restraint System (CRS)
Infants and younger children must be
restrained in an appropriate rearward
facing or forward-facing CRS that has first been properly secured to the seat
of the vehicle. Read and comply with
the instructions for installation and use provided by the manufacturer of the
Child Restraint System.
WARNING
•Always follow the Child RestraintSystem manufacturer’s instruc‐tions for installation and use.
(Continued)
(Continued)
•Always properly restrain your childin the Child Restraint System.
•Do not use an infant carrier or achild safety seat that L

Forward-facing Child Restraint System
A forward-facing Child Restraint Sys‐
tem provides restraint for the child’s body with a harness. Keep children in a
forward-facing Child Restraint System
with a harness until they reach the top height or weight limit allowed by your
Child Restraint System’s manufacturer.
Once your child outgrows the forward-
facing Child Restraint System, your child is ready for a booster seat.
Booster seats
A booster seat is a Child Restraint Sys‐
tem 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 stronger parts of
your child’s body. Keep your children in booster seats until they are big enough
to fit in a seat belt properly.
For a seat belt to fit properly, the lap
belt must lie comfortable across the upper thighs, not the stomach. The
shoulder belt should lie comfortable
across the shoulder and chest and not across the neck or face. Children under
age 13 must always be properly re‐
strained to minimize the risk of injury in an accident, sudden stop or sudden
maneuver.
Installing a Child Restraint
System (CRS)
WARNING
Before installing your Child RestraintSystem always:Read and follow the instructionsprovided by the manufacturer of theChild Restraint System.Failure to follow all warnings and in‐structions could increase the risk ofthe SERIOUS INJURY or DEATH if anaccident occurs.
WARNING
If the vehicle headrest preventsproper installation of a Child Re‐straint System, the headrest of therespective seating position shall bereadjusted or entirely removed.
After selecting a proper Child Restraint
System for your child and checking that the Child Restraint System fits properly
on the seating position, there are three
general steps for a proper installation: •
Properly secure the Child RestraintSystem to the vehicle.
All Child Re‐
straint Systems must be secured to
the vehicle with the lap belt or lap
part of a lap/shoulder belt or with the
ISOFIX toptether and/or ISOFIX an‐ chorage and/or with the support leg.
•
Make sure the Child Restraint Systemis firmly secured. After installing a
Child Restraint System to the vehicle,
push and pull the seat forward and
from side-to-side to verify that it is securely attached to the seat. A Child
Restraint System secured with a seat
belt should be installed as firmly as
possible. However, some side-to-side
movement can be expected. When in‐ stalling a Child Restraint System, ad‐
just the vehicle seat and seatback (up
and down, forward and rearward) so
that your child fits in the Child Re‐ straint System in a confortable man‐
ner.
•
Secure the child in the Child RestraintSystem. Make sure the child is prop‐
erly strapped in the Child Restraint
System according to the Child Re‐ straint System manufacturer’s in‐
structions.
