Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
nWhen working on the engine compartment
lKeep hands, clothing and tools away from the moving fan and engine drive belt.
lBe careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
lDo not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
lDo not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
lBe extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
nWhen working near the electric cooling fan or radiator grille
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 2 )
nSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
nIf you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.

nChecking 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, please refer to the “Owner's
Manual Supplement” or “Scheduled Maintenance”.)
nIf air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
To remove the filter case, lift it
up and pull it out. Replace the fil-
ter with a new one.
The “↑UP” mark shown on the
filter should be pointing up.
nCleaning method
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/cm2
or bar).
If an air gun is not available,
have the filter cleaned by

Introduction
THE IMPORTANCE OF SCHEDULED MAINTENANCE

MAINTENANCE
39
Regular maintenance is essential
to obtaining the highest level of per-
formance, safety and reliability from
your Lexus. It can also enhance your
vehicle’s resale value. This section
of the Warranty and Services Guide
is designed to help you make sure
your vehicle receives proper and
timely maintenance. It includes
factory-recommended maintenance
guidelines as well as logs in which to
document your vehicle’s maintenance
history.
In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks and
visual inspections. These procedures
are listed on pages 42–43 of this
booklet and described in detail in
the “Maintenance” section of the
Owner’s Manual.
It is especially important to check
your vehicle’s engine oil once a
month and to regularly replace the
engine oil and oil filter. Failure to do
so can cause oil starvation and/or oil
gelling, which can result in severe
damage to your vehicle and require
costly repairs that are not covered by
the New Vehicle Limited Warranty.
With proper maintenance and care,
your vehicle will last longer and deliv-
er more dependable, economical
performance. Follow this booklet’s
recommendations and you’ll enjoy
maximum reliability and peace of
mind from your Lexus for many years
to come.
