ENGINE
374AAMA specification, if available, for improved drivability
and emission control system.
Gasolines containing MTBE
Gasolines
that contain MTBE (Methyl T ertiary±Butyl
Ether) are available in the market. If you use a
gasoline mixed with MTBE, make certain that it does
not contain more than 15% of MTBE.
Gasolines containing MMT
Some gasolines contain an octane±enhancing
additive called MMT (methylcyclopentadienyl
manganese tricarbonyl).
Lexus does not recommend the use of gasolines that
contain MMT. If fuels containing MMT are used, your
emission control system may be adversely affected.
The Malfunction Indicator Lamp on the instrument
cluster may come on. If this happens, contact your
Lexus dealer for service.
Gasolines containing alcohol
Gasohol is a mixture of gasoline and ethanol. If you
use gasohol in your Lexus, be sure that it is
unleaded, has an octane rating no lower than 87 and
does not contain more than 10% ethanol. Lexus
does not recommend the use of gasolines
containing methanol.
If you use gasoline containing methanol, use only
gasoline meeting the requirements above and also
containing less than 5% methanol with cosolvents and
corrosion inhibitors for methanol.

tread
Replace the tires when the tread wear indicators
show. The location of the tread wear indicators is
shown by the marks such as ºTWIº or º
Dº marks
molded on the sidewall of each tire.
The tires on your Lexus have built±in tread wear
indicators to help you know when the tires need
replacement. When the tread depth wears to 1.6 mm
(0.06 in.) or less, the indicators will appear. If you can
see the indicators in two or more adjacent grooves, the
tire should be replaced.
The effectiveness of snow tires is lost if the tread
wears down below 4 mm (0.16 in.).
