Introduction
NOTICE
Never use any fuel containing methanol.
Discontinue use of any methanol con-
taining products which may inhibit
proper drivability.
Other fuels
Using fuels that contain Silicone (Si),
MMT (Methylcyclopentadienyl Manga-
nese Tricarbonyl), Manganese (Mn) con-
tained fuel, and other metallic additives,
may cause vehicle and engine damage
or cause misfiring, poor acceleration,
engine stalling, catalyst melting, clog-
ging, abnormal corrosion, life cycle
reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may appear.
NOTICE
Damage to the fuel system or perfor-
mance problems caused by the use of
these other fuels may not be covered by
your New Vehicle Limited Warranty.
Use of MTBE
Kia recommends avoiding fuels contain-
ing 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 pro-
duce vapor lock or hard starting.
NOTICE
Your New Vehicle Limited Warranty may
not cover damage to the fuel system
and any performance problems that are
caused by the use of fuels containing
methanol or fuels containing MTBE
(Methyl Tertiary Butyl Ether) over 15.0%
vol. (Oxygen Content 2.7% weight.)
Gasoline containing MMT
Some gasoline contains harmful manga-
nese- based fuel additives Such as MMT
(Methylcyclopentadienyl Manganese Tri-
carbonyl). Kia does not recommend the
use of gasoline containing MMT. This
type of fuel can reduce vehicle perfor-
mance and affect your emission control
system. The Malfunction Indicator Lamp
(MIL) on the cluster may come on.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system, engine control system
and emission control system.
Fuel Additives
Kia recommends that you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher (for
Europe) or Octane Rating of RON
(Research Octane Number) 91 / AKI
(Anti-Knock Index) 87 or higher (except
Europe).
For customers who do not use good
quality gasolines including fuel addi-
tives regularly, and have problems start-
ing or the engine does not run smoothly,
one bottle of additives should be added
to the fuel tank at every 15,000 km (For
Europe) / 10,000 km (Except Europe).
Additives are available from a profes-
sional workshop along with information
