Introduction
Your new Kia vehicle is designed to use
only unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Never add any fuel system cleaning
agents to the fuel tank other than what
has been specified. (Consult an author-
ized Kia dealer for details.)✽ ✽NOTICE
Tighten the cap until it clicks one time,
otherwise the fuel cap open warning
indicator light will illuminate.
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 instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol. "E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
Kia recommends that customers do not
use fuel with an ethanol content exceed-
ing 10 percent.
✽ ✽
NOTICE
Your New Vehicle Limited Warranty
does not cover damage to the fuel system
or any performance problems caused by
the use of “E85” fuel.
FUEL REQUIREMENTS
WARNING - Refueling
• Do not "top off" after the nozzle
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 prevent fuel
spillage in the event of an acci-
dent.

Introduction
41
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.
✽ ✽NOTICE
Your New Vehicle Limited Warranty
may not cover damage to the fuel system
and any performance problems that are
caused by the use of fuels containing
methanol.
Fuel Additives
Kia recommends that you use good qual-
ity gasolines treated with detergent addi-
tives 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 (7,500
miles) or every engine oil change is rec-
ommended. Additives are available from
your authorized Kia dealer along with
information on how to use them. Do not
mix other additives.
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.

Opening the fuel filler lid
The fuel filler lid must be opened from
inside the vehicle by pushing up the fuel
filler lid opener.
If the fuel filler lid does not open because
ice has formed around it, tap lightly or
push on the lid to break the ice and
release the lid. Do not pry on the lid. If
necessary, spray around the lid with an
approved de-icer fluid (do not use radia-
tor anti-freeze) or move the vehicle to a
warm place and allow the ice to melt.1. Stop the engine.
2. To open the fuel filler lid, push the fuel
filler lid opener button.
3. Pull open the fuel filler lid (1).
4. To remove the cap (2), turn the fuel filler cap counterclockwise.
5. Refuel as needed.
Closing the fuel filler lid
1. To install the cap, turn it clockwise until it “clicks” one time. This indicates that
the cap is securely one time tightened.
2. Close the fuel filler lid and push it in lightly and make sure that it is secure-
ly closed.
FUEL FILLER LID
WARNING - Refueling
Always remove the fuel cap careful-
ly and slowly. If the cap is venting
fuel or if you hear a hissing sound,
wait until the condition stops
before completely removing the
cap.
If pressurized fuel sprays out, it can
cover your clothes or skin and sub-
ject you to the risk of fire and
burns.OTF040026OTF040027

Always check that the fuel cap is installed
securely to prevent fuel spillage in the
event of an accident.✽ ✽
NOTICE
When using an approved portable fuel
container, be sure to place the container
on the ground prior to refueling. Static
electricity discharge from the container
can ignite fuel vapors causing a fire.
Once refueling has begun, contact with
the vehicle should be maintained until
the filling is complete. Use only
approved portable plastic fuel contain-
ers designed to carry and store gasoline.
WARNING - Fire/explosion
risk
Read and follow all warnings post-
ed at the gas station facility. Failure
to follow all warnings will result in
severe personal injury, severe
burns or death due to fire or explo-
sion.
WARNING - Cell phonefires
Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellu-
lar phones can potentially ignite
fuel vapors causing a fire.
WARNING - Static electricity
Before touching the fuel nozzle,
you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.
Do not get back into a vehicle once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
