Introduction
Other fuels
Using fuels such as;- Silicone (Si) contained fuel,
- Ferrocene (Fe) contained fuel,and
- Other metallic additives con- tained fuels,
may cause vehicle and engine dam-
age. Also, the Malfunction Indicator
Lamp (MIL) may illuminate or cause
plugging, misfiring, poor accelera-tion, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-tion, etc.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-sion control system. The malfunction indicator lamp on
the cluster may come on.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damagecomponents of the fuel system,engine control system and emissioncontrol system.
Fuel Additives
HYUNDAI recommends that you usegood quality gasolines treated with
detergent additives such as TOP
TIER Detergent Gasoline, which help
prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance 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 avail-
able, one bottle of additive added to
the fuel tank at every 7,500 miles or
every engine oil change is recom-
mended. Additives are available from
your authorized HYUNDAI dealer
along with information on how to use
them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding
registration and insurance.

Your New Vehicle Limited
Warranty may not cover dam-
age to the fuel system and any
performance problems that are
caused by the use of fuels con-taining methanol.
