MAINTENANCE
431
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
EMISSIONS INSPECTION AND
MAINTENANCE (I/M) PROGRAMS
Some states have vehicle emission inspection programs
which include OBD (On −Board Diagnostics) checks.
The OBD system monitors the operation of the emission
control system. When the OBD system determines that a
problem exists somewhere in the emission control system, the
malfunction indicator lamp comes on. In this case, your vehicle
may not pass the I/M test and need to be repaired. Contact
your Lexus dealer to service the vehicle.
Even if the malfunction indicator lamp does not come on, your
vehicle may not pass the I/M test as readiness codes have not
been set in the OBD system.
Readiness codes are automatically set during ordinary driving.
However, when the battery is disconnected or run down, the
codes are erased. Also, depending on your driving habits, the
codes may not be completely set.
Also, if the malfunction indicator lamp had come on recently
due to temporary malfunction such as a loose fuel tank cap,
your vehicle may not pass the I/M test.
The malfunction indicator lamp will go off after taking several
driving trips, but the error code in the OBD system will not be
cleared unless about 40 trips or more are taken.
If your vehicle does not pass the I/M test and the malfunction
indicator lamp does not come on, contact your Lexus dealer to
prepare the vehicle for re −testing.

FUEL PUMP SHUT OFF
SYSTEM323.
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.

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 5W 30 is the best choice, for good fuel economy and
good starting in cold weather.
If SAE 5W 30 is not available, SAE 10W 30 may be used.
However, it should be replaced with SAE 5W 30 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 GL 5 SAE 75W 90” 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 GL 5 SAE 75W 90”.
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 GL 5 SAE 75W 90” and oils that meet SAE 75W 90
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 GL 5 SAE 75W 90”,
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
