Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance is essential. Lexus recommends the following mainte-
nance.
Scheduled maintenance
Scheduled maintenance should be performed at specified
intervals according to the maintenance schedule.
For full details of your maintenance schedule, read the “Lexus
Service Booklet” or “Lexus Warranty Booklet”.
Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a lit-
tle mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools
and skills. These are best performed by qualified technicians. Even
if you're an experienced do-it-yourself mechanic, we recommend
that repairs and maintenance be conducted by any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional. Any authorized Lexus dealer or repairer will keep a
record of maintenance, which could be useful should you ever
require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Lexus repairer

Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Lexus Service Booklet” or “Lexus Warranty Booklet”.)
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
Cleaning method
If the filter is dirty, clean by
blowing compressed air
through the filter from the
downward side.
Hold the air gun 5 cm (2 in.)
from the filter and blow for
approximately 2 minutes at
500 kPa (5.0 kgf/cm
2 or bar,
72 psi).
If it is not available, have the
filter cleaned by any autho-
rized Lexus dealer or
repairer, or another duly
qualified and equipped pro-
fessional.
Replacement method
Remove the air conditioning
filter 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.
