h nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).

FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all
emissions regulations and provide
exc
ellent 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 higher octane
“Pr
emium” gasoline will not provide any benefit
over “Regular” gasoline in these engines.
While operating on gasoline with an octane
num
ber of 87, 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 an octane number lower
than 87 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.
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.
