FUEL REQUIREMENTS —
GASOLINE ENGINE
2.0L Engine
This engine is designed to meet all emission
regulations, and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline with a recom -
mended RON of 95.
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
your 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.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita -
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts/bolts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
personal injury.

3.6L Engine
This engine is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using
high-quality unleaded gasoline with a
minimum Research Octane Number (RON)
of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle. 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 hesita
-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.

Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these

removal may contain active solvents or
similar ingredients. These can harm fuel
system gasket and diaphragm materials.
