WARNING!

FUEL REQUIREMENTS

While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see an authorized dealer
immediately. Use of gasoline with a lower than
recommended octane number can cause engine failure
and may void or not be covered by the New Vehicle Limited
Warranty.
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives may help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before
considering service for the vehicle.
2.0L E
NGINE
This engine is designed to meet all emissions regulations,
and provide satisfactory fuel economy and performance
when using high-quality unleaded gasoline with a
minimum octane of 95 RON.
