Remove the filter cover.
Remove the air conditioning fil-
ter and replace it with a new
one.
The "UP" mark shown on the
filter should be pointing up.
If the filter is dirty, clean by blow-
ing compressed air through the
filter from the underside.
Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at
72 psi (500 kPa, 5.0 kgf/cm
or bar).
If an air gun is not available,
have the filter cleaned by
your Lexus dealer.
