7464-2. Maintenance
LX570_OM_OM60L96U_(U) Emission inspection and maintenance (I/M) programsSome states have vehicle emission inspection programs which include
OBD (On Board Diagnostics) checks. The OBD system monitors the
operation of the emission control system.
■ If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere in
the emission control system. Your vehicle may not pass the I/M test
and may need to be repaired. Cont act your Lexus dealer to service
the vehicle.
■ Your vehicle may not pass the I/M test:
● When the battery is disconnected or discharged
Readiness codes that are set du ring ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after several driv-
ing trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.

7564-3. Do-it-yourself maintenance
LX570_OM_OM60L96U_(U) CAUTION■
Used engine oil ●
Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation or skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water. ●
Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground. Call
your Lexus dealer, service station or auto parts stor e for information concerning
recycling or disposal. ●
Do not leave used engine oil within the reach of children.
NOTICE■
To prevent serious engine damage
Check the oil level on regular basis. ■
When replacing the engine oil ●
Be careful not to spill engine oil on the vehicle components. ●
Avoid overfilling, as the engine could be damaged.●
Check the oil level on the dipstick every time you refill the vehicle. ●
Be sure the engine oil filler cap is properly tightened.

7804-3. Do-it-yourself maintenance
LX570_OM_OM60L96U_(U) ■
When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire
pressure warning valves and tran smitters must be installed. (  P. 767)
CAUTION■
When replacing wheels ●
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.●
Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident , causing death or serious injury.■
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an acci-
dent.
NOTICE■
Replacing tire pressure warning valves and transmitters ●
Because tire repair or re placement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Le xus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitte rs at your Lexus dealer.●
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valv es and transmitters may not work properly with non-
genuine wheels.

schedule. In dusty areas or areas with heav y traffic flow, more frequent cleaning or
early replacement may be required. (For scheduled maintenance information, refer
to the “Warranty and Services Guide”, “O wner’s Manual Supplement” or “Sched-
uled Maintenance”.) ■
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.

Lexus does not recommend blended gasoline
●
If you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87. ●
Lexus does not recommend the use of gasoline containing methanol.■
Lexus does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy clopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline that contains MMT. If fuel contain-
ing MMT is used, your emission contro l system may be adversely affected.
The malfunction indicator lamp on the inst rument cluster may come on. If this hap-
pens, contact your Lexus dealer for service. ●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol,
including from any pump labeled E30,
E50, E85 (which are only some examples
of fuel containing more than 15% ethanol).DO NOT use gasoline con-
taining more than 15% etha-
nol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

Vehicle specifications
LX570_OM_OM60L96U_(U) ■ Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified gov-
ernment test course. For example, a tire graded 150 would we ar one and a half (1 - 1/2) times as
well on the government cour se as a tire graded 100.
The relative performance of tires depends upon the actual conditions of
their use. Performance may differ significantly from the norm due to varia-
tions in driving habits, service practices and differences in road characteris-
tics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and
they represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on sp ecified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction performance.
Warning: The traction grad e assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turning) trac-
tion.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can cause th e material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
Grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher leve ls of performance on the laboratory
test wheel than the minimum required by law.
