TECHNICAL SPECIFICATIONS397
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 half way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.

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 an octane number lower than
recommended can cause engine failure and may
void 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.
2.0L ENGINE
This engine is designed to meet all
emissions requirements, and provide
satisfactory fuel economy and
performance, when using high-quality
unleaded regular gasoline having an octane rating
of 87, as specified by the (R+M)/2 method. The
use of 91 or higher octane premium gasoline will
allow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or under heavy load
conditions, such as while towing.
3.6L ENGINE
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.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emission regulations and provide
satisfactory fuel economy and
performance when using high-quality
unleaded gasoline having an octane range of 87 to
89 as specified by the (R+M)/2 method. The use of
89 octane plus gasoline is recommended for
optimum performance and fuel economy.
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.
