nEngine oil consumption
lThe amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
lMore oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
lA new engine consumes more oil.
lWhen 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.
lOil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km)
lIf you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
nAfter changing the engine oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer (→P. 142) when the engine is running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to the IGNITION ON mode (but do not start the engine
because otherwise the reset mode will be cancelled). Continue to press
and hold the button until the trip meter displays 000000.
CAUTION
nUsed engine oil
lUsed 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.
lDispose 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 store for information con-
cerning recycling or disposal.
lDo not leave used engine oil within the reach of children.

Maintenance and care
CAUTION
nWhen replacing wheels
lDo 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.
lNever 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.
NOTICE
nReplacing tire inflation pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer.
lEnsure that only Genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.

5-1. Essential information
If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
lThe engine is running, but the vehicle will not move.
lThe vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may be tem-
porarily towed using a cable or chain secured to the emergency towing
eyelet(s). This should only attempted on hard, surfaced roads for short
distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.
Towing eyelets
If towing is necessary, we recommend having your vehicle towed by your
Lexus dealer or a commercial towing service, using a lift-type truck or a flat
bed truck.
Use a safety chain system for all towing, and abide by all state/provincial
and local laws.
If towing from the rear, the vehicle’s front wheels and axles must be in good
condition. (→P. 377)
If they are damaged, use a towing dolly or flat bed truck.

6-1. Specifications
nLexus does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus DOES NOT recommend the use of gasoline that contains MMT. If fuel con-
taining MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
NOTICE
nNotice on fuel quality
lDo not use improper fuels. If improper fuels are used the engine will be damaged.
lDo not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert-
ers causing the emission control system to malfunction.
lDo not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance problems.
lIS250: Use of unleaded gasoline with an octane rating lower than 91 may result
in engine knocking. Persistent knocking can lead to engine damage and should
be corrected by refueling with higher octane unleaded gasoline.
lIS350: Use of unleaded gasoline with an octane rating lower than 91 may result
in engine knocking and significantly reduced performance. Persistent knocking
can lead to engine damage and should be corrected by refueling with higher
octane unleaded gasoline.
nFuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot start-
ing, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.
nWhen refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.

Vehicle specifications
nDOT quality grades
All passenger vehicle tires must conform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found where
applicable on the tire sidewall between tread shoulder and maximum
section width.
For example: Treadwear 200 Traction AA Temperature A
nTreadwear
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 wear one and a half (1 - 1 /2) times as
well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of
their use, however, and may depart significantly from the norm due to varia-
tions in driving habits, service practices and differences in road characteris-
tics and climate.
nTraction 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 specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turning) trac-
tion.
