2015 KIA OPTIMA HYBRID fuel pump

Introduction
21
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. (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.)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,
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.
"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.
