2020 HYUNDAI GENESIS G90 open gas tank

Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as
MMT (Methylcyclopentadienyl Manganese Tricarbonyl).
Genesis Branded Vehicle does not recommend the use of gasoline contain-
ing 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.
Detergent Fuel Additives
Genesis Branded Vehicle recommends that you use good quality gasolines treat-
ed 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 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, detergent-based
fuel additives that you can purchase 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 12 months is recommended.
Additives are available from your authorized retailer of Genesis Branded prod-
ucts 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.
• Determine that acceptable fuel is available.

Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
• Read and follow all warnings
posted at the gas station.
• Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
• Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
• Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
