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 “Checking the
engine oil level” described below.
325.USED ENGINE OIL
CAUTION
 Used engine oil contains potentially harmful
contaminants which m ay cause skin disorders such
as inflammation or skin cancer, so care should be
taken to avoid prolonged and repeated contact with
it. To remove used engine oil from your skin, wash
thoroughly with soap and water.
 Do not leave used oil within the reach of children.
 Dispose of used oil and used oil filters only in a safe
and acceptable manner. Do not dispose of used oil
and used oil filters in household trash, in sewers or
onto the ground. Call your Lexus dealer or a service
station for information concerning recycling or
disposal.

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.

Synthetic oil information labelNOTICE
Vehicles with synthetic oil information label only:
Use of differential oil other than “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90” or its
equivalent may damage the dif ferential gear of your vehicle
and diminish fuel efficiency. For the reasons mentioned
above, Lexus recommends use of “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90”.
Another differential oil of matching quality can also be
used, (but note that despite the similarity in nomenclature
between “Toyota Genuine Differential Synthetic gear oil
API GL5 SAE 75W90” and oils that meet SAE 75W90
specifications, compliance with the SAE specification
does not guarantee that an oil has all characteristic
required to avoid the problem described above.) If you are
unable to locate an equivalent to “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90”,
contact your Lexus dealer for further details or another
duly qualified and equipped professional.

6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire valve caps. Without the
valve caps, dirt or moisture could get into the
valve core and cause air leakage. If the caps have
been lost, have new ones put on as soon as
possible.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire needs frequent refilling, have it checked by your
Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation):
 Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire separation
 A greater possibility of tire damage from road
hazards
High tire pressure (overinflation):
 Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire damage from road
hazards
