Introduction
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.
Fuel Additives
HYUNDAI recommends that you usegood quality gasolines treated with
detergent 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, additives that
you can buy separately may be added
to the gasoline. If TOP TIER Detergent
Gasoline is not available, one bottle of
additive added to the fuel tank at every
7,500 miles or every engine oil change
is recommended. Additives are avail-
able from your authorized HYUNDAI
dealer along with information on how
to use them. Do not mix other addi-
tives.
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.
