Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as:
• Silicone fuel additive
• Ferrocene (iron-based) fuel additive
• Other metallic-based fuel additives
may result in cylinder misfire, poor acceleration, engine stalling, damage to the catalyst,
or abnormal corrosion, and may cause damage to the engine resulting in a reduction in
the overall life of the powertrain.
The Malfunction Indicator Lamp (MIL) may illuminate.
NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels or
fuel additives may not be covered by your New Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Do not use gasoline containing 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
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 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 according to the maintenance
schedule is recommended (refer to the "Scheduled Maintenance Services" in chapter 9).
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.
• Determine that acceptable fuel is available.
