Gasoline containing MMT
Some gasoline contains harmful
manganese-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 damage
components of the fuel system.
Fuel Additives
HYUNDAI recommends that you use
good 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.
CAUTION
Your New Vehicle Limited
Warranty may not cover damage
to the fuel system and any per-
formance problems that are
caused by the use of fuels con-
taining methanol.
