Introduction
21
Your new vehicle is designed to use
only unleaded fuel having a pump
octane number ((R+M)/2) of 87
(Research Octane Number 91) or
higher. (Do not use methanol blend-
ed fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult an
authorized Kia dealer for details.)
• Tighten the cap until it clicks onetime, otherwise the Check Engine light will illuminate.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline. Pursuant to EPA regulations, ethanol
may be used in your vehicle.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Ethanol provides less
energy than gasoline and it attracts
water, and it is thus likely to reduce
your fuel efficiency and could lower
your MPG results.
Methanol may cause drivability prob-
lems 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 prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasoline or gasohol containing
methanol.
2. Leaded fuel or leaded gasohol.
3. Gasohol containing more than 15% ethanol.
WARNING - Refueling
• Do not "top off" after the noz- zle automatically shuts off.
Attempts to force more fuel
into the tank can cause fuel
overflow onto you and the
ground causing a risk of fire.
Always check that the fuel cap is installed securely to pre-
vent fuel spillage, especially
in the event of an accident.

No modifications or additions
should be made by the user which
would either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted
to remove slack.
When you fasten the seat belt, be careful not to latch the seat belt in
buckles of other seat. It's very dan-
gerous and you may not be pro-
tected by the seat belt properly.
Do not unfasten the seat belt and do not fasten and unfasten the seat
belt repeatedly while driving. This
could result in loss of control, and
an accident causing death, serious
injury, or property damage.
When fastening the seat belt, make sure that the seat belt does
not pass over objects that are hard
or can break easily. Driver's seat belt warning
As a reminder to the driver, the seat
belt warning light will illuminate and
warning chime will sound for approx-
imately 6 seconds each time engine
start/stop button is ON if the seat belt
is unfastened.
WARNING- Seat belt
buckle
Do not allow foreign material
(gum, crumbs, coins, etc.) to
obstruct the seat belt buckle.
This may prevent the seat belt
from fastening securely.

Safety features of your vehicle
The seat belt automatically adjusts to
the proper length only after the lap
belt portion is adjusted manually so
that it fits snugly around your hips. If
you lean forward in a slow, easy
motion, the belt will extend and let
you move around. If there is a sud-
den stop or impact, however, the belt
will lock into position. It will also lock
if you try to lean forward too quickly.
✽ ✽NOTICE
If you are not able to pull out the
seat belt from the retractor, firmly
pull the belt out and release it. Then
you will be able to pull the belt out
smoothly.
Seat belts - Front passenger and
rear seat 3-point system withcombination locking retractor
To fasten your seat belt:
Combination retractor type seat belts
are installed in the rear seat posi-
tions to help accommodate the
installation of child restraint systems.
Although a combination retractor is
also installed in the front passenger
seat position, it is strongly recom-
mended that children always be
seated in the rear seat. NEVER
place any infant restraint system in
the front seat of the vehicle.
This type of seat belt combines the
features of both an emergency lock-
ing retractor seat belt and an auto-
matic locking retractor seat belt. To
fasten your seat belt, pull it out of the
retractor and insert the metal tab into
the buckle. 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 automatically adjusts to the proper
length only after the lap belt portion
of the seat belt is adjusted manually
so that it fits snugly around your hips.
When the seat belt is fully extended
from the retractor to allow the instal-
lation of a child restraint system, the
seat belt operation changes to allow
the belt to retract, but not to extend
(Automatic Locking Retractor Type).
Refer to “Using a child restraint sys-
tem” in this section.
✽ ✽
NOTICE
Although the combination retractor
provides the same level of protection
for seated passengers in either emer-
gency or automatic locking modes,
have the seated passengers use the
emergency locking feature for improv-
ed convenience. The automatic locking
function is intended to facilitate child
restraint installation. To convert from
the automatic locking feature to the
emergency locking operation mode,
allow the unbuckled seat belt to fully
retract.

Safety features of your vehicle
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 as low as possi-
ble. Check periodically to insure that
the belt fits. 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 sys-
tem in the rear seat. If a larger child
(over age 13) must be seated 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 13 and under should be
restrained securely in the rear seat.
NEVER place a child age 13 and
under in the front seat. NEVER place
a rear facing child seat in the front
seat of a vehicle.If the shoulder belt portion slightly
touches the child’s neck or face, try
placing the child closer to the center of
the vehicle. If the shoulder belt still
touches their face or neck they need to
be returned to a child restraint system.
Restraint of pregnant women
Pregnant women should wear
lap/shoulder belt assemblies when-
ever possible according to specific
recommendations by their doctors.
The lap portion of the belt should be
worn AS SECURELY AND LOW AS
POSSIBLE.
WARNING- Small children
Do not allow small children to
ride in the vehicle without an
appropriate child restraint sys-
tem. If the shoulder belt comes
in contact with your child's neck
or face your child is too small to
ride in the vehicle. In a crash the
seat belt will inflict injury to your
child's neck, throat and face.
WARNING - Pregnant women
Pregnant women must never
place the lap portion of the seat
belt above or on the abdomen
where the fetus is located. The
force of the seat belt during a
collision will crush the fetus.

CHILD RESTRAINT SYSTEM (CRS)
Children Always in the RearChildren 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 serious-
ly 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.
WARNING - Restraint
Location
Never install a child or infant
seat on the front passenger's
seat. A child riding in the front
passenger seat can be forceful-
ly struck by an inflating airbag
and seriously injured.
WARNING - Hot Child
Restraint
A child restraint system can
become very hot if it is left in a
closed vehicle on a sunny day.
Be sure to check the seat cover,
buckles and latches before
placing a child in the restraint
system.
