2015 KIA Optima fuel type

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.
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
available, one bottle of additive
added to the fuel tank at 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.
CAUTION
Your New Vehicle Limited Warranty 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.)

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.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.
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 - 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.
WARNING - Smoking
DO NOT use matches or a lighter
and DO NOT SMOKE or leave a
lit cigarette in your vehicle while
at a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
CAUTION
Do not pull the handle exces- sively, otherwise the luggagecompartment area trim orrelease handle may be damaged.

Features of your vehicle
Engine coolant temperature gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the engine over-
heats" in chapter 6.
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Fuel gauge
The fuel gauge indicates the approx-
imate amount of fuel remaining in the
fuel tank. 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.
WARNING - Fuel gauge
Stop and obtain additional fuel
as soon as possible after the
warning light comes on or when
the gauge indicator comes
close to the E level. Running out
of fuel can expose vehicle occu-
pants to danger.
CAUTION - Low fuel
Avoid driving with extremelylow fuel level. Running out offuel could cause the engine tomisfire, damaging the catalyticconverter.OTF044057

Fuel Economy
Distance to empty (Range) (1)
The Distance to empty (range) is
the estimated distance the vehicle
can be driven with the remaining
fuel.
- Distance range : 50 ~ 1999 km or
30 ~ 1999 mi.
If the estimated distance is below 50 km (30 mi.), the trip computer
will display "---" as distance to
empty.✽ ✽ NOTICE
• If the vehicle is not on level ground
or the battery power has been
interrupted, the distance to empty
function may not operate correctly.
• The distance to empty may differ from the actual driving distance as
it is an estimate of the available
driving distance.
• The trip computer may not regis- ter additional fuel if less than 1.6
gallons (6 liters) of fuel are added
to the vehicle.
• The fuel economy and distance to empty may vary significantly based
on driving conditions, driving
habits, and condition of the vehicle.
