Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
Retighten the wheel nuts, in the same pattern, to the
torques listed in the Torque Specifications table. Go
through the sequence a second time to verify that specific
torque has been achieved. Retighten to specifications after
25 miles (40 km) and check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel stud
nuts to specifications at each lubrication interval.
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is espe-
cially 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 tight-
ened 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 pre-
viously tightened until final torque is achieved.
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 — GASOLINE ENGINE
While operating on gasoline with the required octane num-
ber, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard mak-
ing a heavy knocking sound, see a dealer immediately. Use
of gasoline with a lower than recommended octane num-
ber can cause engine failure and may void or not be cov-
ered 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.
6.4L ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emis-
sions 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.
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.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents, corro-
sion 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 fur-
ther aide in minimizing engine and fuel sys-
tem deposits. When available, the usage of
TOP TIER Detergent Gasoline is recommended. Visit

Gasoline retailers.
