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
3.5M93 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 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 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, now and then, you may notice light knocking for a
short time while accelerating or driving up hills. This is no
cause for concern.
Gasolines containing detergent additives
Lexus recommends the use of gasoline that contain
detergent a dditives to avoid buildup of engine deposits.
For further details, ask your Lexus dealer or a local gasoline
retailer.
Quality gasoline
Automobile manufacturers in U.S., Europe and Japan
have developed a specificat ion for quality fuel named
WorldWide Fuel Charter (WWFC) that is expected to be
applied world wide. The WWFC consists of three
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 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.

BATTERY RECHARGINGPRECAUTIONS
During recharging, the battery is producing hydrogen
gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be
sure to disconnect the ground cable.
2. Make sure the power switch on the recharger is off when
connecting the charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an unconfined area. Do
not charge the battery in a garage or closed room
where there is not sufficient ventilation.
 Only do a slow charge (5 A or less). Charging at a
quicker rate is dangerous. The battery may explode
causing personal injuries.
NOTICE
Never recharge the battery while the engine is running.
Also, be sure all accessories are turned off.

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 yourself from burning, do not replace the
light bulbs while they are hot.
 Vehicles with discharge headlight—Do not
disassemble, repair or take apart the low beam
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.
 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.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights such as headlights may
temporarily fog up when the lens becomes wet in the rain or in
a car wash. This is not a problem because the fogging is
caused by the temperature dif ference between the outside and
inside of the lens, just like the windshield fogged up in the rain.
However, if there is a large drop of water on the inside of the
lens, or if there is water pooled inside the light, contact your
Lexus dealer.

Automatic car wash
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some type of
brushes, unfiltered washing water, or the washing process

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.

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 carcleaning 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.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
