■Cleaning method
If the filter is dirty, clean by blow-
ing compressed air through the
filter from the downward side.
Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at 73
psi (500 kPa, 5.1 kgf/cm
2 or
bar).
If it is not available, have the filter
cleaned by your Lexus dealer.
■Replacement method
Remove the air conditioning fil-
ter from the filter case and
replace it with a new one.
The “UP” marks shown on the
filter and the filter case should
be pointing up.

■Checking interval
Inspect and replace the air conditioning filter according to the maintenance sched-
ule. In dusty areas or areas with heavy traffic flow, early replacement may be
required. (For scheduled maintenance information, refer to the “Warranty and Ser-
vices Guide/Owner’s Manual Supplement/Scheduled Maintenance”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■To prevent damage to the system
●When using the air conditioning system, make sure that a filter is always installed.
●When cleaning the filter, do not clean the filter with water.
