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.

You will find many safety precautions
and recommendations throughout
this section, and throughout this man-
ual. The safety precautions in this sec-
tion are among the most important.
Always wear your seat belt
A seat belt is your best protection in
all types of accidents. Air bags are
designed to supplement seat belts,
not replace them. So even though
your vehicle is equipped with air
bags, ALWAYS make sure you and
your passengers wear your seat
belts, and wear them properly.
Restrain all children
All children under age 13 should ride
in your vehicle properly restrained in
a rear seat, not the front seat. Infants
and small children should be
restrained in an appropriate child
restraint. Larger children should use
a booster seat with the lap/shoulder
belt until they can use the seat belt
properly without a booster seat.
Air bag hazards
While air bags can save lives, they
can also cause serious or fatal
injuries to occupants who sit too
close to them, or who are not prop-
erly restrained. Infants, young chil-
dren, and shorter adults are at the
greatest risk of being injured by an
inflating air bag. Follow all instruc-
tions and warnings in this manual.
Driver distraction
Driver distraction presents a serious
and potentially deadly danger, espe-
cially for inexperienced drivers.
Safety should be the first concern
when behind the wheel and drivers
need to be aware of the wide array of
potential distractions, such as drowsi-
ness, reaching for objects, eating,
personal grooming, other passen-
gers, and using cellular phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel
to focus on activities other than driv-
ing. To reduce your risk of distraction
or getting into an accident:
• ALWAYS set up your mobiledevices (i.e., MP3 players, phones,
navigation units, etc.) when your
vehicle is parked or safely stopped.
IMPORTANT SAFETY PRECAUTIONS

33
Safety features of your vehicle
ONLY use your mobile devicewhen allowed by laws and when
conditions permit safe use. NEVER
text or email while driving. Most
states have laws prohibiting drivers
from texting. Some states and
cities also prohibit drivers from
using handheld phones.
NEVER let the use of a mobile device distract you from driving.
You have a responsibility to your
passengers and others on the road
to always drive safely, with your
hands on the wheel as well as your
eyes and attention on the road.Control your speed
Excessive speed is a major factor in
crash injuries and deaths. Generally,
the higher the speed, the greater the
risk, but serious injuries can also
occur at lower speeds. Never drive
faster than is safe for current condi-
tions, regardless of the maximum
speed posted.
Keep your vehicle in safe con-
dition
Having a tire blowout or a mechani-
cal failure can be extremely haz-
ardous. To reduce the possibility of
such problems, check your tire pres-
sures and condition frequently, and
perform all regularly scheduled
maintenance.

WARNING- Uprightingseat
Do not press the release lever
on a manual seatback without
holding and controlling the
seatback. The seatback will
spring upright possibly impact-
ing you or other passengers.
WARNING- Loose objects
Do not place anything in the dri-
ver's foot well or under the front
seats. Loose objects in the dri-
ver's foot area could interfere
with the operation of the foot
pedals.WARNING- Driver respon-
sibility for passengers
The driver must advise the pas-
sengers to keep the seatback in
an upright position whenever
the vehicle is in motion. If a seat
is reclined during an accident,
the restraint system's ability to
restrain will be greatly reduced.

WARNING- Seat cushion
Occupants should never sit on
aftermarket seat cushions or sit-
ting cushions. The passenger's
hips may slide under the lap por-
tion of the seat belt during an
accident or a sudden stop.
WARNING- Driver’s seat
Never attempt to adjust the seat while the vehicle is mov-
ing. This could result in loss
of control of your vehicle.
Do not allow anything to inter- fere with the normal position
of the seatback. Storing items
against the seatback could
result in serious or fatal injury
in a sudden stop or collision.
Sit as far back as possible from the steering wheel while still
maintaining comfortable con-
trol of the your vehicle. A dis-
tance of at least 10" from your
chest to the steering wheel is
recommended. Failure to do so
can result in air bag inflation
injuries to the driver.

Child restraint system (CRS)
Infants and younger children must be
restrained in an appropriate rear-fac-
ing 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.
✽ ✽NOTICE
After an accident, have a Kia dealer
check the child restraint system, seat
belts, tether anchors and lower
anchors.
Selecting a Child Restraint
System (CRS)
When selecting a CRS for your child,
always:
Make sure the CRS has a label
certifying that it meets applicable
Federal Motor Vehicle Safety
Standards (FMVSS 213).
Select a child restraint based on your child’s height and weight. The
required label or the instructions
for use typically provide this infor-
mation.
Select a child restraint that fits the vehicle seating position where it
will be used.
Read and comply with the warn- ings and instructions for installation
and use provided with the child
restraint system.
WARNING
-
Child Restraint Installation
An improperly secured child
restraint can increase the risk
of serious injury or death in an
accident. Always take the fol-
lowing precautions when using
a child restraint system:
Always follow the child restraint system manufactur-
er’s instructions for installa-
tion and use.
(Continued)
(Continued)
Always properly restrain yourchild 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 posi-
tion should 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.

How does the air bag system
operate?
Air bags are activated (able to
inflate if necessary) only when the
engine start/stop button has been
changed to ON position.
The appropriate air bags inflate instantly in the event of a serious
frontal collision or side collision in
order to help protect the occupants
from serious physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate based upon the severity of a
collision and its direction. These
two factors determine whether the
sensors produce an electronic
deployment/ inflation signal.
Air bag deployment depends on a number of factors including vehicle
speed, angles of impact, and, the
density and stiffness of the vehi-
cles or objects which your vehicle
hits in the collision. The determin-
ing factors are not limited to those
mentioned above. The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to
see the air bags inflate during an
accident.
It is much more likely that you will
simply see the deflated air bags
hanging out of their storage com-
partments after the collision.
In addition to inflating in serious side collisions, side and/or curtain
air bags will inflate if the sensing
system detects a rollover.
When a rollover is detected, side and/or curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. In order to help provide protection,
the air bags must inflate rapidly.
The speed of the air bag inflation is
a consequence of extremely short
time in which to inflate the air bag
between the occupant and the
vehicle structures before the occu-
pant impacts those structures. This
speed of inflation reduces the risk
of serious or life-threatening
injuries and is thus a necessary
part of the air bag design.
However, air bag inflation can also
cause injuries which can include
facial abrasions, bruises and bro-
ken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
There are even circumstances under which contact with the
steering wheel or passenger air
bag can cause fatal injuries,
especially if the occupant is
positioned excessively close to
the steering wheel or passenger
air bag.
