Introduction
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 one
time, 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.
Do not use gasohol containing more
than 15 percent ethanol, and do not
use gasoline or gasohol containing
any methanol.
Either of these fuels may cause dri-
vability problems and damage to the
fuel system, engine control system
and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
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.
