2020 KIA OPTIMA PHEV fuel cap

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.
FUEL REQUIREMENTS

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

✽ ✽
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.

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 disap-
pears, open the fuel tank cap, and
slowly refuel the vehicle. If you quick-
ly pour fuel into the fuel tank, the fuel
may overflow out of the fuel tank.

Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
CHARGE : Shows that the energy
made by the vehicle is
being converted to
electrical energy.
(Regenerated energy)
ECO : Shows that the vehicle is being driven in an Eco-
friendly manner.
POWER : Shows that the vehicle is exceeding the Eco-
friendly range.
✽ ✽NOTICE
Based on the hybrid system gauge,
the "EV" indicator comes on or off.

WARNING - Hot radiator
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
✽ ✽
NOTICE
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by a low fuel warning light which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the
low fuel warning light may come
on earlier than usual due to the
movement of fuel in the tank.
✽ ✽ NOTICE - Fuel gauge
Running out of fuel can expose vehi-
cle occupants to danger. You must
obtain additional fuel as soon as pos-
sible after the warning light comes
on or when the gauge indicator
comes close to the "E (Empty)"
level.
✽ ✽NOTICE
Fuel display may not be accurate if
the vehicle is on an incline.
CAUTION- Low fuel
Avoid driving with an extremely
low fuel level. Running out offuel could cause the engine tomisfire damaging the catalyticconverter.
