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. (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.

NOTICE
Tighten the cap until it clicks one
time, otherwise the fuel cap open
warning indicator
light will illu-
minate.
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:

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 in the event
of an accident.
CAUTION
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied. (Consult an authorized Kia
dealer for details.)
