EXTERIOR EQUIPMENT

CAUTION
Do not smoke, cause sparks or allow open flames
when refuelling. The fumes are flammable.
 When opening the cap, do not remove the cap
quickly. In hot weather, fuel under pressure could
cause injury by spraying out of the filler neck if the
cap is suddenly removed.

2. To remove the fuel tank cap, turn the cap slowly
counterclockwise, then pause slightly before
removing it. The removed cap can be stored on the
back side of the fuel filler door.
It is not unusual to hear a slight swoosh when the cap is
opened. When installing the cap, turn the cap clockwise
until you hear a click.
If the cap is not tightened securely, the malfunction
indicator lamp comes on. Make sure the cap is tightened
securely.
The indicator lamp goes off after driving several times.
If the indicator lamp does not go off, contact your Lexus
dealer as soon as possible.

DRIVING TIPS
309
Slow down and downshift before descending
steep or long downhill grades. Do not make
sudden downshifts.
 Avoid holding the brake pedal down too long or
too frequently. This could cause the brakes to
overheat and result in reduced braking
efficiency.
HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST
LONGER
Getting more kilometer/mileage from a liter/gallon of fuel
is easy ± just take it easy. It will help make your vehicle
last longer, too. Here are some specific tips on how to
save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure.
Check the pressure every two weeks, or at least once
a month. Underinflation causes tire wear and wastes
fuel.
 Do not carry unneeded weight in your vehicle.
Excess weight puts a heavier load on the engine,
causing greater fuel consumption.
 Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently.
Remember, however, that on cold winter days this
may take a little longer. 
Accelerate slowly and smoothly. Avoid jackrabbit
starts.
 Avoid long engine idling. If you have a long wait
and you are not in traffic, it is better to turn off the
engine and start again later.
 Avoid engine overrevving . Use a gear position
suitable for the road on which you are traveling.
 Avoid continuous speeding up and slowing
down. Stop±and±go driving wastes fuel.
 Avoid unnecessary stopping and braking.
Maintain a steady pace. Try to time the traffic si gnals
so you only need to stop as little as possible or take
advantage of through streets to avoid traffic lights.
Keep a proper distance from other vehicles to avoid
sudden braking. This will also reduce wear on your
brakes.
 Avoid heavy traffic or traffic jams whenever
possible.
 Do not rest your foot on the brake pedal. This
causes needless wear, overheating and poor fuel
economy.
 Maintain a moderate speed on highways. The
faster you drive, the greater the fuel consumption. By
reducing your speed, you will cut down on fuel
consumption.
 Keep the front wheels in proper alignment. Avoid
hitting the curb and slow down on rough roads.

MAINTENANCE

GENERAL MAINTENANCE
Listed below are the general maintenance items that
should be performed at the intervals specified. It is
recommended that any problem you notice be brought
to the attention of your Lexus dealer or qualified service
shop for their advice.
CAUTION
Make these checks only where adequate ventilation can
be obtained if you run the engine.
Vehicle exterior
Items listed below should be performed from time to
time, unless otherwise specified.
Tire pressure
Check the pressure with a gauge every two weeks, or at
least once a month and adjust as shown on the tire
pressure label. See page 397 for additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 399 for additional information.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary. Tire rotation
Rotate
the tires every 12000 km (7500 miles). See page
398 for additional information.
Fluid leaks
Check underneath for leaking fuel, oil, water or other
fluid after the vehicle has been parked for a while. If you
smell fuel fumes or notice any leak, have the cause
found and corrected immediately.
Doors and engine hood
Check that all doors, including trunk lid, operate
smoothly and all latches lock securely. Make sure the
engine hood secondary latch secures the hood when the
primary latch is released.

Gasolines 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 that 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 vehicleperformance problems.
If drivability problems are encountered (poorhot starting, vaporizing, engine knock, etc.),discontinue its use.
Take care not to spill gasohol during refueling.Gasohol may cause paint damage.

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.
