GAUGES, METERS AND SERVICE REMINDER INDICATORS
61
(d) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn
off the engine, and check for the cause. Look first at the
engine drive belt.
If it is loose or broken, the generator will not charge
the battery properly.
If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however,
until the battery is discharged. Turn off the air
conditioning, blower, radio, etc., and drive directly to the
nearest Lexus dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(e) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the
road to a safe place and stop the engine immediately.
Call a Lexus dealer or qualified repair shop for
assistance.
The light may occasionally flicker when the engine is
idling or it may come on briefly after a hard stop. There
is no cause for concern if it then goes out when the
engine is accelerated slightly.
The light may come on when the oil level is extremely
low. It is not designed to indicate low oil level, and the
oil level must be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on± even for one block. It may ruin the engine.

MAINTENANCE
355
Engine compartment
Items listed below should be checked from time to
time, e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page
432 for additional information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and
ºLOWº lines on the see±through reservoir when the
engine is cold. See page 383 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not
have to add distilled water. For longer life of the battery,
however, see page 415 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 391
for additional information.
Engine oil level
Check the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 378 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ºHOTº or ºCOLDº range depending on the fluid temperature. See page 393 for additional information.
Exhaust system
Look
for cracks, holes and loose supports. If you notice
any change in the sound of the exhaust or smell exhaust
fumes, have the cause located and corrected
immediately. (See engine exhaust cautions in Section
3±1.)

ENGINE
376The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way
the vehicle is driven.
More oil is consumed under driving conditions such as
high speeds and frequent acceleration and
deceleration.
A new engine consumes more oil, since its pistons,
piston rings and cylinder walls have not become
conditioned.
When judging the amount of oil consumption, keep
in mind that the oil may have become diluted,
making it difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips
and consumes a normal amount of oil, the dipstick may
not show any drop in the oil level at all, even after 1000
km (600 miles) or more. This is because the oil is
gradually
becoming diluted with fuel or moisture, making
it appear that the oil level has not changed.
The diluting ingredients evaporate out when the vehicle
is then driven at high speeds, as on an expressway,
making it appear that oil is excessively consumed after
driving at high speeds.
Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum
level so that oil function will not be impaired. Therefore,
it is essential that the oil level be checked regularly.
Lexus recommends that the oil level be checked every
time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.
For detailed information on oil level check, see
ºChecking the engine oil levelº on page 378.

CHECKING THE ENGINE OILLEVEL
62E001a
With the engine at operating temperature and turned
off, check the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level
spot. After turning off the engine, wait a few minutes for
the oil to drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go,
or the reading will not be correct.

4. Pull the dipstick out and look at the oil level on the end.
If it is between the full line ( 5 ) and the low line ( 4 ),
it is O.K.

If the oil level is below or only slightly above the low
line,
add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a
time, checking the dipstick. The approximate quantity of
oil needed to fill between the low line and the full line on
the dipstick is indicated below for reference.
When the level reaches within the correct range, return
the filler cap and turn the cap clockwise until you hear a
click.
Oil quantity. L (qt., lmp. qt.) 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be
damaged. C heck the oil level on the dipstick once
again after adding the oil.
