Use of MTBE
KIA recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
KIA recommends that you use good
quality gasolines treated with detergent
additives such as TOP TIER Detergent
Gasoline, which help prevent deposit for-
mation in the engine. These gasolines
will help the engine run cleaner and
enhance performance of the Emission
Control System. For more information on
TOP TIER Detergent Gasoline, please
go to the website (www
.toptiergas.com).
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does not
run smoothly, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 12,000 km or every
engine oil change is recommended.
Additives are available from your author-
ized KIA dealer along with information on
how to use them. Do not mix other addi-
tives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg- istration and insurance.
Determine that acceptable fuel is avail- able. No special break-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob- lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)

Infant or small child
You should be aware of the specific
requirements in your country. Child
and/or infant seats must be properly
placed and installed in the rear seat. For
more information about the use of these
restraints, refer to “Child restraint sys-
tem” in this section.✽ ✽
NOTICE
Small children are best protected from
injury in an accident when properly
restrained in the rear seat by a child
restraint system that meets the require-
ments of the Safety Standards of your
country. Before buying any child
restraint system, make sure that it has a
label certifying that it meets the Safety
Standard of your country. The restraint
must be appropriate for your child's
height and weight. Check the label on
the child restraint for this information.
Refer to “Child restraint system” in this
section.
Larger children
Children who are too large for child
restraint systems should always occupy
the rear seat and use the available
lap/shoulder belts. The lap portion should
be fastened and snugged on the hips
and as low as possible. Check if the belt
fits periodically. A child's squirming could
put the belt out of position. Children are
given the most safety in the event of an
accident when they are restrained by a
proper restraint system in the rear seat. If
a larger child (over age 12) must be seat-
ed in the front seat, the child should be
securely restrained by the available
lap/shoulder belt and the seat should be
placed in the rearmost position. Children
age 12 and under should be restrained
securely in the rear seat. NEVER place a
child age 12 and under in the front seat.
NEVER place a rear facing child seat in
the front seat of a vehicle.
WARNING
Every person in your vehicle needs
to be properly restrained at all
times, including infants and chil-
dren. Never hold a child in your
arms or lap when riding in a vehi-
cle. The violent forces created dur-
ing a crash will tear the child from
your arms and throw the child
against the interior. Always use a
child restraint appropriate for your
child's height and weight.

Safety features of your vehicle
The ODS is designed to detect the pres-
ence of a properly-seated front passen-
ger and determine if the passenger's
front air bag should be enabled (may
inflate) or not. The driver's front air bag is
not affected or controlled by the ODS.Main components of ODS
A detection device located within thefront passenger seat track.
Electronic system to determine whether passenger air bag systems
should be activated or deactivated.
A indicator light located on the instru- ment panel which illuminates the
words PASSENGER AIR BAG “OFF”
indicating the front passenger air bag
system is deactivated.
The instrument panel air bag warning light is interconnected with the occu-
pant detection system.
If the front passenger seat is occupied by
a person that the system determines to
be of adult size, and he/she sits properly
(sitting upright with the seatback in an
upright position, centered on the seat
cushion with their seat belt on, legs com-
fortably extended and their feet on the
floor), the PASSENGER AIR BAG “OFF”
indicator will turn off and the front pas-
senger's air bag will be able to inflate, if
necessary, in frontal crashes.
You will find the PASSENGER AIR BAG
“OFF” indicator on the center facia panel.
This system detects the conditions 1~4
in the following table and activates or
deactivates the front passenger air bag
based on these conditions. Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person’s legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt.
The ODS (Occupant Detection System)
may not function properly if the passen-
ger takes actions which can defeat the
detection system. These include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or rest- ing them on other locations which
reduce the passenger weight on the
front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.

WARNING
Riding in an improper position or
placing weight on the front passen-
ger's seat when it is unoccupied by
a passenger adversely affects the
occupant detection system (ODS).
(Continued)
Condition and operation in the front passenger occupant detection system
*1) The system judges a person of adult size as an adult. When a smaller adult sits inthe front passenger seat, the system may recognize him/her as a child depending
on his/her physique and posture.
*2) Do not allow children to ride in the front passenger seat. When a smaller child than the same age sits in the front passenger seat, the system may recognize him/her
as an infant depending on his/her physique or posture.
*3) Never install a child restraint system on the front passenger seat.
*4) The PASSENGER AIR BAG "OFF" indicator may turn on or off when a child above 12 months to 12 years old (with or without child restraint system) sits in the front
passenger seat. This is a normal condition.

Air bags can only be used once –have an authorized KIA dealer
replace the air bag immediately
after deployment.
A smaller-stature adult who is not seated correctly (for example:
seat excessively reclined, leaning
on the door or center console, or
hips shifted forward in the seat)
can cause a condition where the
advanced frontal air bag system
senses less weight than if the
occupant were seated properly
(sitting upright with the seatback
in an upright position, centered
on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the
floor).
This condition can result in an
adult potentially being misclassi-
fied and illumination of the PAS-
SENGER AIR BAG “OFF” indica-
tor.(Continued)
If you change the weight on thefront passenger seat, the PAS-
SENGER AIR BAG “OFF” indica-
tor may turn on or off for a few
seconds, disabling or enabling
the passenger air bag.
Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or after market seat
heater to the front passenger
seat. This can adversely affect the
occupant detection system.
Do not sit on sharp objects such as tools when occupying the front
passenger seat. This can adverse-
ly affect the occupant detection
system.
Do not use accessory seat covers on the front seats.
Accident statistics show that chil- dren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recommend-
ed that child restraints be secured
in a rear seat, including an infant
riding in a rear-facing infant seat,
a child riding in a forward-facing
child seat and an older child rid-
ing in a booster seat.
(Continued)WARNING
Even though your vehicle isequipped with the occupant
detection system, never install a
child restraint system in the front
passenger's seat. A deploying air
bag can forcefully strike a child
resulting in serious injuries or
death. Any child age 12 and
under should ride in the rear seat.
Children too large for child
restraints should use the avail-
able lap/shoulder belts. No mat-
ter what type of crash, children of
all ages are safer when restrained
in the rear seat.
If the PASSENGER AIR BAG “OFF” indicator is illuminated
when the front passenger's seat
is occupied by an adult and
he/she sits properly (sitting
upright with the seatback in an
upright position, centered on the
seat cushion with their seat belt
on, legs comfortably extended
and their feet on the floor), have
that person sit in the rear seat.
