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.

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
nChecking the engine oil
Park the vehicle on level ground. After turning off the engine, wait
more than 5 minutes for the oil to drain back into the bottom of
the engine.
Hold a rag under the end and pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check the
oil level.
Wipe the dipstick and reinsert it fully.

nEngine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced with
SAE 0W-20 at the next oil
change.
The 0W portion of the oil viscosity rating indicates the characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
The 20 in 0W-20 indicates the oil viscosity when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.

Determining Your
Maintenance Interval:
Months vs. Mileage
Lexus recommends obtaining sched-
uled maintenance for your vehicle
every six months or 5,000 miles,
whichever occurs first.
For example:
•If at six months you have driven
less than 5,000 miles, you
should obtain maintenance at six
months; don’t wait until 5,000
miles.
•If you drive 5,000 miles in less
than six months, you should
obtain maintenance at 5,000
miles; don’t wait until six months.
Be sure to keep an eye on your
mileage so that you obtain mainte-
nance when recommended. If you are
a low-mileage driver, mark your cal-
endar to remind yourself to obtain
maintenance every six months.
Special Operating
Conditions
In addition to standard maintenance
items, vehicles that are driven under
special operating conditions require
further maintenance service. These
special operating conditions, which
put added demands on a vehicle,
include:
•Driving on dirt roads or on dusty
roads
•Repeated trips of less than five
miles in temperatures below
32° F or 0° C
•Extensive idling and/or low-
speed driving for long distances,
such as police, taxi or door-to-
door delivery use
If you drive primarily under any
of the conditions noted, you
should replace the engine oil
and oil filter every six months or
5,000 miles. Some of these
special operating conditions
require other maintenance items;
these items are indicated in each
maintenance chart.
