1998 Lexus ES300 oil

MAINTENANCE
182
Tire rotation
Rotate the tires every 12000 km (7500 miles). See page 208 for additional
information.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after the vehicl\
e
has been parked for a while. If you smell fuel fumes or notice any leak, h\
ave
the cause found and corrected immediately.
Doors and engine hood
Check
that all doors, including trunk lid, operate smoothly and all latches lo\
ck
securely. Make sure the engine hood secondary latch secures the hood when
the primary latch is released.
Vehicle interior
Items listed below should be checked regularly, e.g. while performing
periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlight, stop lights, tail lights, turn signal lights, and o\
ther
lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning buzzers function
properly.
Steering wheel
Check that it has the specified freeplay. Be alert for changes in steering
condition, such as hard steering, excessive freeplay or strange noise.
Seats
Check that all front seat controls such as seat adjusters, seatback recliner, etc.
operate smoothly. Check that the head restraints move up and down smoothly
and that the locks hold securely in any latched position.
Seat belts
Check that the seat belt system such as buckles, retractors and anchors operat\
e
properly and smoothly. Make sure the belt webbing is not cut, frayed, worn
or damaged.

MAINTENANCE183
Accelerator pedal
Check the pedal for smooth operation and uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and the proper clearance and freeplay.
Check the brake booster function.
Brakes
At a safe place, check that the brakes do not pull to one side when appl\
ied.
Parking brake
Check that the pedal has the proper travel and that, on a safe incline, your
vehicle is held securely with only the parking brake applied.
Automatic transmission ºParkº mechanism
Check the lock release button of the selector lever for proper and smooth
operation. On a safe incline, check that your vehicle is held securely with the
selector lever in ºPº position and all brakes released.
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 227 for additional
information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and ºLOWº line\
s on the
see±through reservoir when the engine is cold. See page 201 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 219 for additional
information.
Brake fluid level
Make sure the brake fluid level is correct. See page 205 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 198 for additional information.

DO±IT±YOURSELF SERVICEPRECAUTIONS
If you perform maintenance yourself, be sure to follow the correct
procedure given in this Section.
You should be aware that improper or incomplete servicing may result in
operating problems.
Performing do±it±yourself maintenance during the warranty period may
affect your warranty coverage. Read the separate Lexus Warranty statement
for details and suggestions.
This Section gives instructions only for those items that are relatively eas\
y for
an owner to perform. As explained in Section 5, there are still a number \
of
items that must be performed by a qualified technician with special tools.
For information on tools and parts for do±it±yourself maintenance, se\
e ºParts
and toolsº.
Utmost care should be taken when working on your vehicle to prevent
accidental injury. Here are a few precautions that you should be especially
careful to observe:
CAUTION

When the engine is running, keep hands, clothing, and tools
away from the moving fan and engine drive belt.
(Removing rings, watches, and ties is advisable.)

Right after driving, the engine compartment ± the engine,
radiator, exhaust manifold and power steering fluid
reservoir, etc. ± will be hot. So be car eful not to touch them.
Oil and other fluids may also be hot.

Do not smoke, cause sparks or allow open flames near fuel
or the battery. Their fumes are flammable.

Be extremely cautious when working on the battery. It
contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or other
solid supports.

Use eye protection whenever you work on or under your
vehicle where you may be exposed to flying or falling
material, fluid spray, etc.

INTRODUCTION189
NOTICE

Remember that battery and ignition cables carry high currents or
voltages. Be careful of accidentally causing a short circuit.

Before closing the engine hood, check to see that you have not
forgotten any tools, rags, etc.

Do not drive with the air cleaner removed, or excessive engine wear
could result. Also backfiring could cause a fire in the engine
compartment.

Do not overfill automatic transmission fluid, or the transmission could
be damaged.

Be careful not to scratch the glass surface with the wiper frame.
PARTS AND TOOLS
Here is a list of parts and tools you will need to perform do±it±y\
ourself
maintenance. Remember all Lexus parts are designed in metric sizes, so your
tools must be metric.
Checking the engine oil level
Parts (if level is low):

Use API grade SH, ºEnergy±Conserving IIº or SJ, ºEnergy±Conservingº
multigrade engine oil or ILSAC multigrade engine oil. For recommended
oil viscosity, see page 200.
Tools:

Rag or paper towel

Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low):

Ethylene±glycol coolant

Demineralized or distilled water
Tools:

Funnel (only for adding coolant)

Gasolines containing MTBE
Gasolines that contain MTBE (Methyl Tertiary±Butyl Ether) are
available in the market. If you use a gasoline mixed with MTBE, make
certain that it does not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor drivability and/or p\
oor
fuel economy, you should stop using them.
Gasolines containing MMT
Some gasolines contain an octane±enhancing additive called MMT
(methylcyclopentadienyl manganese tricarbonyl).
Lexus does not recommend the use of gasolines that contain MMT. If fuels
containing MMT are used, your emission control system may be adversely
affected. The Malfunction Indicator Lamp on the instrument cluster may
come on. If this happens, contact your Lexus dealer for service.
Gasolines containing alcohol
Gasohol is a mixture of gasoline and ethanol. If you use gasohol in your
Lexus, be sure that it is unleaded, has an octane rating no lower than 87
and does not contain more than 10% ethanol. Lexus does not recommend
the use of gasolines containing methanol.
If you use gasoline containing methanol, use only gasoline meeting the
requirements above and also containing less than 5% methanol with
cosolvents and corrosion inhibitors for methanol.
NOTICE
 Do not use gasohol other than stated above. It will cause fuel system
damage or vehicle performance problems.
 If drivability problems are encountered (poor hot starting, vaporizing,
engine knock, etc.), discontinue its use.
 Take care not to spill gasohol during refueling. Gasohol may cause
paint damage.
