2020 KIA OPTIMA fuel

Introduction
41
"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 15 percent.
✽ ✽
NOTICE
Your New Vehicle Limited Warranty
does not cover damage to the fuel sys-
tem or any performance problems
caused by the use of “E85” fuel.
✽ ✽
NOTICE
Never use any fuel containing
methanol. Discontinue use of any
methanol containing product which
may inhibit proper drivability.
Other fuels
Using fuels that contain Silicone (Si),
MMT (Manganese, Mn), Ferrocene
(Fe), and other metalic additives,
may cause vehicle and engine dam-
age or cause misfiring, poor acceler-
ation, engine stalling, catalyst melt-
ing, clogging, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽
NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warranty.
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.
✽ ✽
NOTICE
Your New Vehicle Limited
Warranty may not cover damage to
the fuel system and any perform-
ance problems that are caused by
the use of fuels containing methanol
or fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight.)

Introduction
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives such as
MMT(Methylcyclopentadienyl
Manganese Tricarbonyl). Kia does not
recommend the use of gasoline con-
taining MMT. This type of fuel can
reduce vehicle performance and affect
your emission control system. The
Malfunction Indicator Lamp on the
cluster may come on.
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,
engine control system and emission
control system.
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance perform-
ance 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, addi-
tives that can be purchased sepa-
rately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
should be added to the fuel tank at
every 12,000 km (7,500 miles) or
every engine oil change is recom-
mended. 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 regardingregistration and insurance.
Determine that acceptable fuel is available.

Features of your vehicle
Opening the fuel filler lid
The fuel filler lid must be opened
from inside the vehicle by pressing
the fuel filler lid opener button.
✽ ✽NOTICE
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
radiator 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, turn the fuel filler cap (2) counterclockwise(3).
5. Refuel as needed.
Closing the fuel filler lid
1. To install the cap, turn it clockwise until it “clicks” once. This indicates
that the cap is securely tightened.
2. Close the fuel filler lid and push it in lightly making sure that it is
securely closed.
✽ ✽NOTICE
There may be an intermittent noise
near the refueling hole while the
engine is idling if the fuel cap is not
closed securely. This occurs normal-
ly with the OBD system.
✽ ✽NOTICE
When refueling on unlevel ground,
the fuel gauge may not point to the F
position.
It is not a malfunction. If you move
your vehicle to a level ground, the fuel
gauge will move to the full position.

Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
✽ ✽
NOTICE
Tighten the cap until it clicks once,
otherwise the fuel cap open warning
indicator light will illuminate.
WARNING- Fire/explo-
sion risk
Read and follow all warnings
posted at the gas station facili-
ty. Failure to follow all warnings
may result in severe personal
injury, severe burns or death
due to fire or explosion.WARNING- Static electricity
Before touching the fuel noz- zle, you should eliminate
potentially dangerous static
electricity discharge by touch-
ing another metal part of the
vehicle, a safe distance away
from the fuel filler neck, noz-
zle, 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
fabric (polyester, satin, nylon,
etc.) capable of producing stat-
ic electricity. Static electricity
discharge can ignite fuel
vapors resulting in rapid burn-
ing. If you must reenter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source.WARNING- Refueling
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap. If
pressurized fuel sprays out, it
can cover your clothes or skin
and subject you to the risk of
fire and burns.

Features of your vehicle
Make sure to refuel your vehicle
according to the “Fuel requirements”
suggested in chapter 1.
If the fuel filler cap requires replace-
ment, use only a genuine Kia cap or
the equivalent specified for your vehi-
cle. An incorrect fuel filler cap can
result in a serious malfunction of the
fuel system or emission control sys-
tem.
WARNING- Cell phonefires
Do not use cellular phones
while refueling. Electric current
and/or electronic interference
from cellular phones can poten-
tially ignite fuel vapors causing
a fire.
WARNING- Smoking
DO NOT use matches or a
lighter and DO NOT SMOKE or
leave a lit cigarette in your vehi-
cle while at a gas station espe-
cially during refueling.
Automotive fuel is highly flam-
mable and can, when ignited,
result in fire.
WARNING- Refueling & Vehicle fires
When refueling, always shut the
engine off. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire. Once
refueling is complete, check to
make sure the filler cap and
filler door are securely closed,
before starting the engine.
CAUTION- Exterior paint
Do not spill fuel on the exterior surfaces of the vehicle. Anytype of fuel spilled on paintedsurfaces may damage the paint.
WARNING- Portable fuel
container
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 containers designed to
carry and store gasoline.
