2017 KIA OPTIMA PLUG-IN HYBRID fuel cap

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
use of:

Emergency fuel filler lid release
If the fuel filler lid does not open using
the remote fuel filler lid release, you can open it manually. Remove the panel
in the cargo area. Pull the handle out
slightly.
In this case, slowly open the fuel tank cap, because the fuel tank may be
highly pressurized. If fuel leaks out, or
if air hisses out, wait until it disappears, open the fuel tank cap, and slowly re‐
fuel the vehicle. If you quickly pour fuel
into the fuel tank, the fuel may over‐ flow out of the fuel tank.
CAUTION
Do not pull the handle excessively,otherwise the luggage compartmentarea trim or release handle may bedamaged.
WARNING
nRefueling dangers
Automotive fuels are flammable ma‐terials. When refueling, please notethe following guidelines carefully.Failure to follow these guidelinesmay result in severe personal injury,severe burns or death by fire or ex‐plosion.•Read and follow all warnings pos‐ted at the gas station facility.
•Before refueling note the locationof the Emergency Gasoline Shut-Off, if available, at the gas stationfacility.
(Continued)
(Continued)
•Before touching the fuel nozzle,you should eliminate potentiallydangerous static electricity dis‐charge by touching another metalpart of the vehicle, a safe distanceaway from the fuel filler neck,nozzle, or other gas source.
•Do not get back into a vehicle onceyou have begun refueling since youcan generate static electricity bytouching, rubbing or sliding againstany item or fabric (polyester, sat‐in, nylon, etc.) capable of produc‐ing static electricity. Static elec‐tricity discharge can ignite fuel va‐pors resulting in rapid burning. Ifyou must reenter the vehicle, youshould once again eliminate poten‐tially dangerous static electricitydischarge by touching a metal partof the vehicle, away from the fuelfiller neck, nozzle or other gasolinesource.

•When using an approved portablefuel container, be sure to place thecontainer on the ground prior torefueling. Static electricity dis‐charge from the container can ig‐nite fuel vapors causing a fire.Once refueling has begun, contactwith the vehicle should be main‐tained until the filling is complete.Use only approved portable plasticfuel containers designed to carryand store gasoline.
•Do not use cellular phones whilerefueling. Electric current and/orelectronic interference from cellu‐lar phones can potentially ignitefuel vapors causing a fire.
•When refueling, always shut theengine off. Sparks produced byelectrical components related tothe engine can ignite fuel vaporscausing a fire. Once refueling iscomplete, check to make sure thefiller cap and filler door are secure‐ly closed, before starting the en‐gine.
