Other fuels
Using fuels that contain Silicone (Si),
MMT (Manganese, Mn), Ferrocene
(Fe), and Other metalic additives,
may cause vehicle and engine dam-
age or cause misfiring, poor acceler-
ation, engine stalling, catalyst melt-
ing, clogging, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽

NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warranty.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives Such as
MMT(Methylcyclopentadienyl
Manganese Tricarbonyl). Kia does not
recommend the use of gasoline con-
taining MMT. This type of fuel can
reduce vehicle performance and affect
your emission control system. The
Malfunction Indicator Lamp 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
performance and damage components
of the fuel system, engine control sys-
tem and emission control system.
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www.toptiergas.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 should
be added to the fuel tank at every
7,500miles or every engine oil change
is recommended. Additives are avail-
able from your authorized Kia dealer
along with information on how to use
them. Do not mix other additives.

Maintenance
Normal Maintenance Schedule - Non Turbo Models
The following maintenance services must be performed to ensure good emission control and performance.
Keep receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the
frequency of service is determined by whichever occurs first.
