Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).
Torque Patterns
After 25 miles (40 km) check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.
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.

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 a 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 hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.

NGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and performance
when using high quality unleaded regular
gasoline having a posted octane number of 87 as
specified by the (R+M)/2 method. The use of
higher octane premium gasoline is not required, as
it will not provide any benefit over regular gasoline
in these engines.

EFORMULATED ASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
"reformulated gasoline". Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
