WARNING
Do not use air cleaner components as
grab handles. These
components may
break if you are using them to support
your weight. Failure to comply may re-
sult in personal injury or damage to ve-
hicle components.
WARNING
Do not push on the under hood air
door with hands.
This door is held
closed with a spring which may shut
close unexpectedly. Failure to comply
may result in personal injury.
CAUTION
Failure to replace air filter at proper in-
tervals
may
result
in passage of dirt/
debris into the engine or the “dusting”
of an engine resulting in significant
equipment damage.
Your vehicle is equipped with an air inlet
restriction indicator
. Service the filter
elements when the air inlet restriction
indicator locks in the extreme Up position.
Paper elements require care and proper
handling because they are critical to
engine service life.
The engine air filter is located on the top of
the engine just below the hood. There are
(4) fasteners that hold the cover to the filter
housing.
If the vehicle has the under hood air intake
option, the air intake solenoid and the
airline will need to be removed to access
the air filter.
