2005 LEXUS LS430 oil change

GAUGES, METERS AND SERVICE REMINDER INDICATORS
95
In normal conditions, due to engine oil consumption, this
message may a
ppear earlier than the specified service interval
of the scheduled maintenance. This is because the engine oil
is consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see “Facts about engine oil consumption” on page
450.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.

This message indicates that the engine oil maintenance
data has been reset. After replacing the engine oil, be sure
to reset the maintenance data.
To reset the data, perform the following operations:
1. Push the “ODO/TRIP” button to change the display to
blank.
2. Turn the ignition switch off.
3. Turn the ignition switch to “ON” with the trip meter
“RESET” button held down.
4. Keep pushing the “RESET” button for longer than 5
seconds after the ignition is turned on.
After the above operation, the master warning light comes
on, a warning tone sounds and the above message
appears to inform you that the engine oil maintenance
data has been reset. (U.S.A. only)

NOTICE
Do not put any object on the panel or push it hard. Doing
this may damage the panel.
20L362a
Your automatic changer can store up to 6 CDs and play
selected CDs or continuously play all the CDs set in the player.
When you set CDs into the player, make sure their labels face
up. If not, the player will display “ERROR1” and the CD
number.
NOTICE
 Never try to disassemble or oil any part of the CD
player. Do not insert anything except a CD into the
slot.
 Do not insert a CD upon another one, or it will damage
the automatic changer. Insert only one CD into the
slot at a time.

MAINTENANCE
428Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 496 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 466 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 452 for additional
information.
Power steering fluid level
Check the level through the reservoir. The level should be in
the “HOT” or “COLD” range depending on the fluid
temperature. See page 467 for additional information.
Exhaust system
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” on page 297.)
Vehicle interior
Items listed below should be checked regularly, e.g. while
performing periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail lights, turn signal
lights, and other 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 ha s the specified free play. Be alert for changes
in steering condition, such as hard steering, excessive free
play 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 operate properly and smoothly. Make sure the
belt webbing is not cut, frayed, worn or damaged.

324.FACTS ABOUT ENGINE OILCONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
 Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems. The 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 by high−
speed driving and frequent
acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 lmp. qt./600 miles)
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.

327.Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use
Lexus approved “Toyota Genuine Motor Oil” or equivalent to
satisfy the following grade and viscosity.
Oil grade: API grade SL “Energy −Conserving” or ILSAC
multigrade engine oil.
Recommended viscosity (SAE): 5W −30
62L042
Outside temperature
SAE 5W30 is the best choice, for good fuel economy and
good starting in cold weather.
If SAE 5W30 is not available, SAE 10W30 may be used.
However, it should be replaced with SAE 5W30 at the next
oil change.
Oil identification marks
62L038
 API Service Symbol ILSAC Certification Mark
Either or both API registered marks are added to some oil
containers to help you select the oil you should use.
 The API Service Symbol is located anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institut e) designation such as SL.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W −30. “Energy− Conserving”, shown
in the lower portion, indicates that the oil has fuel −saving
capabilities.
 The ILSAC (International L ubricant Standardization and
Approval Committee) Certification Mark is displayed on the
front of the container.
