Snowplow Prep Packages are available as a factory installed
option. These packages include components necessary to
equip your vehicle with a snowplow.
NOTE:
Before installation of a snowplow it is highly recommended
that the owner/installer obtain and follow the recommenda -
tions contained within the current Body Builders Guide. See
your authorized dealer, installer or snowplow manufacturer
for this information. There are unique electrical systems that
must be connected to properly assure operator safety and
prevent overloading vehicle systems. Before Plowing
• Check the hydraulic system for leaks and proper fluid
level.
• Check the mounting bolts and nuts for proper tightness.
• Check the runners and cutting edge for excessive wear. The cutting edge should be ¼ to ½ in (6 cm to 1.2 cm) above
ground in snow plowing position.
• Check that snowplow lighting is connected and func -
tioning properly.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision. Do
not expect that the airbag will perform as described
earlier in this manual.
CAUTION!
The “Lamp Out” indicator could illuminate if exterior
lamps are not properly installed.

6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine. This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number 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.
While operating on gasoline with an octane number 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 gaso -
line 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.8
