Air filter restriction gauge
The restriction gauge, located on
the clean-air side of the air cleaner
upper housing, shows if the air filter
is clogged. Refer to “Engine
Compartment” in Service Points
chapter.
The air filter element should be
replaced when the colored band on
the gauge reaches the CHANGE
FILTER mark. Engine performance
and fuel economy are adversely
affected when maximum restriction
is reached. After servicing the air
filter element, reset the restriction
gauge by pressing the button the
end of the gauge.
