2014 KIA Optima Hybrid fuel

H2
Kia Hybrid-Electric Vehicle (HEV)
uses a gasoline engine and an
electric motor for power. The elec-
tric motor is powered by a 270V
high voltage HEV battery.
The HEV computer decides when
to use the engine and when to use
electric motor, according to driv-
ing conditions. At times, both are
used simultaneously.
By turning off the engine under
certain conditions and using the
electric motor alone, the HEV sys-
tem saves fuel.
When the HEV battery reaches a
low state of charge, the engine will
cycle on and off to recharge the
battery. Charging also occurs
when decelerating by using
regenerative braking.Hybrid System Display
Many of the displays provide infor-
mation about the hybrid system,
such as the ECO Level and ECO
Score.
The ECO Level displays inform the
driver of the vehicle's fuel efficiency.
If the vehicle is driven economically,
the ECO Level rises. When the vehi-
cle is driven in EV mode, there is a
reduction in carbon dioxide (CO2)
emissions.
The Total ECO Score display indi-
cates the number of times the ECO
Level has reached its maximum.ECO Level display
When the vehicle is started, the ECO
Level display will indicate level 4. If
you drive economically, the ECO
Level will increase. However, if you
do not drive economically, the ECO
Level will decrease.

When the hybrid vehicle shuts
off
When the high voltage battery or 12-
volt battery discharges, or fuel tank is
empty, the hybrid system may not
operate.
If the Hybrid system stops operating
while the vehicle is moving, reduce
the vehicle speed gradually. Pull your
vehicle off the road in a safe area,
and shift the transmission in to Park
(P) position and;
1.Turn on the hazard warning flash-ers.
2.Using the Start button, turn the system OFF. Try to start the Hybrid
system by applying the brake
pedal and pushing the start button.
3.If the Hybrid system will not oper- ate, refer to "EMERGENCY
STARTING" in chapter 6. Before you try to jump start the vehi-
cle,
confirm the fuel level. If the fuel level
is low add more fuel before attempt-
ing as emergancy start.

Never touch electric wires or
cable. If exposed electric wires
or cables are visible inside or
outside of your vehicle, an elec-
tric shock may occur.

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 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.)Gasoline containing alcohol andmethanol
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 10% 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.
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.
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. Kia recom-
mends 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
accident.

Introduction
41
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as MMT (Methylcyclopentadi-
enyl Manganese Tricarbonyl).
Kia does not recommend the use of
gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Use of MTBE
Kia recommends avoiding fuels con-
taining 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
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system.
CAUTION
Your New Vehicle LimitedWarranty may not cover damageto the fuel system and any per-formance problems that arecaused by the use of fuels con-taining methanol or fuels con-taining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)

Introduction
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which helps
prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance of the Emission Control
System. For more information on
TOP TIER Detergent Gasoline,
please go to the website (www
.top-
tiergas.com).
For Customers who do not use TOP
TIER Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at 7,500 miles or every
engine oil change is recommended.
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 registration and insurance.
Determine that acceptable fuel is available.
