440 TECHNICAL SPECIFICATIONS
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being sheared or
the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles/
kilometers of operation to allow the wheel nuts to become
properly set. All wheel nuts should first be firmly seated
against the wheel. The wheel nuts should then be
tightened to recommended torque. Tighten the wheel nuts
to final torque in increments. Progress around the bolt
circle, tightening the wheel nut opposite to the wheel nut
just previously tightened until final torque is achieved.
FUEL REQUIREMENTS — GASOLINE ENGINE
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 satisfactory fuel
economy and performance when using high
quality unleaded gasoline having a posted
octane number of 87 as specified by the (R+M)/2 method.

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.

UEL
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 will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to further
aide in minimizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Detergent
Gasoline retailers.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
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.
