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 threeway catalytic converter to lose its
effectiveness and the emission control system to
function improperly. Also, this can increase
maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number 91) or
higher. For improved vehicle performance, the use of
premium unleaded gasoline with an Octane Rating of 91
(Research Octane Number 96) or higher is recommended. Use of unleaded fuel with an Octane Rating or Research
Octane Number lower than stated above will cause persistent
heavy
knocking. If it is 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.
Gasolines containing detergent additives
Lexus recommends the use of gasoline that contain
detergent additives to avoid buildup of engine deposits.
For further details, ask your Lexus dealer or a local gasoline
retailer.
Quality gasoline
Automotive manufacturers in the U.S., Europe and Japan
have developed a specification for quality fuel named
WorldWide 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 4 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 performance
problems.
 If drivability problems are encountered (poor hot
starting, vaporizing, engine knock, etc.), discontinue
its use.
 Take care not to spill gasohol during refueling.
Gasohol may cause paint damage.
Fuel tank capacity

FUEL PUMP SHUT OFF SYSTEM
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 has been damaged and it is
in need of repair. In this case, do not restart the engine.
FACTS ABOUT ENGINE OIL CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
 Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.

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 headlights —
 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.

Fuel
filler door: Do not apply water (high −pressure car wash,
for example) at or near the fuel tank inlet with the fuel filler door
opened. If the water enters the air vent, you may experience
trouble with refueling or rough engine idling.
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substances 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 or
cause 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
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.
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.
Apply wax once a month or if the vehicle surface does not repel
water well.
1. Always wash and dry the vehicle before you begin waxing,
even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become
extremely weathered, use a car −cleaning polish, followed by
a separate wax. Carefully follow the manufacturer’s
instructions and precautions. Be sure to polish and wax the
chrome trim as well as the paint.

Remove dirt on the leather in the following ways:
1. Wipe it off lightly using a soft cloth (e.g. gauze) dampened
with 5% solution of neutral detergent for wool.
2. Wring water from a clean cloth and thoroughly wipe off all
traces of detergent with it.
3. Wipe off
the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet
may cause the hardening or shrinking of the leather.
NOTICE
 Dirt or sand adhered to the leather may damage the
treated surface and cause it to wear earlier. Remove
dirt or sand using a vacuum cleaner.
 If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.
 Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions for
cleaning the leather as these could cause
discoloring.
 Use of a nylon brush or synthetic fiber cloth, etc. may
scratch the fine grained surface of the leather.
Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight may cause the
leather surface to harden and shrink. Keep your
vehicle in a shaded area, especially in the summer.
 The interior of your vehicle is apt to heat up on hot
summer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing wax as
these tend to stick to leather when warm.
 Improper cleaning of the leather upholstery could
result in discoloration or staining.

BODY
416
Nonleather Trim (Dash)
The nonleather trim may be easily cleaned with a mild
soap or detergent and water.
First vacuum over the upholstery to remove loose dirt. Then,
using a sponge or soft cloth, apply the soap solution to the
synthetic leather. After allowing it to soak in for a few minutes
to loosen the dirt, remove the dirt and wipe off the soap with a
clean damp cloth. If all the dirt does not come off, repeat the
procedure. Commercial foaming −type cleaners are also
available which work well. Follow the manufacturer’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline or window cleaner
on the interior.
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. The seat belts may be cleaned with mild soap and water or
with lukewarm water.
Use a cloth or sponge. As you are cleaning, check the belts for
excessive wear, fraying or cuts.
NOTICE

Use a good foamtype shampoo to clean the carpets.
 Do not use dye or bleach on the belts — it may
weaken them.
 Do not use the belts until they become dry.
 The windows may be cleaned with any household
window cleaner.
 Do not apply detergent to or wet the automatic wiper
control sensor when cleaning the inside of the
windshield.
 When cleaning the inside of the rear window, be
careful not to scratch or damage the heater wires or
connectors.
