FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller
fuel tank opening. The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle on pumps with
leaded gas will not.
At a minimum, the gasoline you use should meet the
specifications of ASTM D4814 in the U.S.A. and CGSB
3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the three±way catalytic converter to lose itseffectiveness and the emission control system tofunction improperly. Also, this can increasemaintenance costs.
Octane rating
Select premium unleaded gasoline with an Octane Rating
of 91 (Research Octane Number 96) or higher for optimum
engine performance. However, if such premium type
cannot be obtained, you may temporarily use unleaded
gasoline with an Octane Rating as low as 87 (Research
Octane Number 91). Use of unleaded fuel with an octane number or rating lower
than stated above will cause persistent heavy knocking. If
severe, this will lead to engine damage.
If your engine knocks ...
If you detect heavy knocking even when using the
recommended fuel, or if you hear steady knocking while
holding a steady speed on level roads, consult your Lexus
dealer.
However, occasionally, you may notice light knocking for a
short time while accelerating or driving up hills. This is normal
and there is no need for concern.
Gasoline containing detergent additives
Lexus recommends the use of gasoline that contains
detergent additives to avoid build±up of engine deposits.
However, all gasoline sold in the U.S. contains detergent
additives to keep clean and/or clean intake systems.
Quality gasoline
Automotive manufacturers in the U.S., Europe and Japan
have developed a specification for quality fuel named
World±Wide Fuel Charter (WWFC) that is expected to be
applied world wide. The WWFC consists of four
categories
that depend on required emission levels. In the
U.S., category 3 has been adopted. The WWFC improves
air quality by providing for better emissions in vehicle
fleets, and customer satisfaction through better vehicle
performance.

Cleaner burning gasoline
Cleaner burning gasoline, including reformulated
gasoline that contains oxygenates such as ethanol or
MTBE is available in many areas.
Lexus recommends the use of cleaner burning gasoline and
appropriately blended reformulated gasoline. These types of
gasoline provide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.
Oxygenates in gasoline
Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or 15%
MTBE. 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.
Gasoline containing MMT
Some gasoline contain an octane enhancing additive
called MMT (Methylcyclopentadienyl Manganese
Tricarbonyl).
Lexus does not recommend the use of gasoline that contains
MMT. If fuel containing MMT is 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.
Gasoline quality
In a very few cases, you may experience driveability problems
caused by the particular gasoline that you are using. If you
continue to have unacceptable driveability, try changing
gasoline brands. If this does not rectify your problem, then
consult your Lexus dealer.
NOTICE
Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performanceproblems.
If driveability problems are encountered (poor hotstarting, vaporizing, engine knock, etc.), discontinueits use.
Take care not to spill gasohol during refueling.Gasohol may cause paint damage.

number of turns and in the same direction as step 1.
REPLACING LIGHT BULBS
The illustration on the following pages show the locations of
light bulbs. If it is necessary to replace a bulb, take your vehicle
to your Lexus dealer as soon as possible. Use bulbs with the
bulb numbers and wattage ratings given in the table.
CAUTION
 To prevent burning yourself, do not replace the light
bulbs while they are hot.
 Halogen bulbs have pressurized gas inside and
require special handling. They can burst or shatter if
scratched or dropped. Hold a bulb only by its plastic
or metal case. Do not touch the glass part of a bulb
with bare hands.
Vehicles with discharge headlightsÐ
 Do not touch the high voltage socket when the
headlight turns on. 20000 V is momentarily generated
and may cause severe injury by electric shock.
 Do not disassemble, repair or take apart the headlight
bulbs, connector, power supply circuits and rotated
components. Or you may be injured by electric
shocks. Call your dealer when the headlights fail to
work or have to be replaced or disposed of.
NOTICE
Only use a bulb of the listed type.

398Plastic wheel ornaments:
The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substance splashes an ornament, be sure to wash it off with
water and check if the ornament is damaged.
CAUTION
Do not attach the heavily damaged plastic wheel
ornament. It may fly off the wheel and cause accidents
while the vehicle is moving.
Aluminum wheels: Use only a mild soap or neutral detergent.
Urethane bumpers and side moldings: Wash carefully. Do
not scrub with abrasive cleaners. The bumper and side
molding faces are soft.
Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.
NOTICE
Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic orcause damage.
3. Rinse thoroughly ± dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard ± you might scratch the
paint.
Automatic car wash
NOTICE
To prevent damage to the antenna, make sure it isremoved before driving your vehicle through anautomatic car wash.
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.

Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as
possible. Several types of foam cleaners are available; some
are in aerosol cans and others are powders or liquids which
you mix with water to produce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam. Rub in overlapping
circles. Do not apply water ± the best results are obtained by
keeping the carpet as dry as possible. Read the shampoo
instructions and follow them closely.
