320TECHNICAL SPECIFICATIONS

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.
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.
2.4L ENGINE
This engine is designed to meet all
emission regulations and provide
excellent fuel economy and performance
when using high quality unleaded regular
gasoline having a octane rating of 87 using the
(R+M)/2 method. The use of premium gasoline is
not recommended, as it will not provide any benefit
over regular gasoline in these engines.
REFORMULATED GASOLINE
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.
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.
