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 431 for a dditional information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 433 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 according to the maintenance schedule.
(For scheduled maintenance information, please refer to
the ªOwner's Manual Supplement/Maintenance
Scheduleº.) See page 432 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.

FACTS ABOUT ENGINE OILCONSUMPTION
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.
The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way
the vehicle is driven.
More oil is consumed under driving conditions such as
high speeds and frequent acceleration and
deceleration.
A new engine consumes more oil, since its pistons,
piston rings and cylinder walls have not become
conditioned.
When judging the amount of oil consumption, keep
in mind that the oil may have become diluted,
making it difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips
and consumes a normal amount of oil, the dipstick may
not show any drop in the oil level at all, even after 1000
km (600 miles) or more. This is because the oil is
gradually becoming diluted with fuel or moisture, making
it appear that the oil level has not changed.
The diluting ingredients evaporate out when the vehicle
is then driven at high speeds, as on an expressway,
making it appear that oil is excessively consumed after
driving at high speeds.

CHECKING TIRE PRESSURE
63E004±1
The recommended cold tire pressures, tire size and
the vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or
at least once a month. And don't forget the spare! The
air pressure for the spare tire should be 220 kPa (2.2
kgf/cm
2 or bar, 32 psi). Incorrect tire pressure can
reduce tire life and make your vehicle less safe to drive. Low tire pressure results in excessive wear, poor
handling, reduced fuel economy, and the possibility of
blowouts from overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead. If the tire
pressure is excessively low, there is the possibility of
wheel deformation and/or tire
separation. So keep your
tire pressures at the pr oper level. If a tire needs frequent
refilling, have it checked by your Lexus dealer.
High tire pressure produces a harsh ride, handling
problems, excessive wear at the center of the tire tread,
and a greater possibility of tire damage from road
hazards.
The following instructions for checking tire pressure
should be observed:
 The pressure should be checked only when the
tires are cold. If your vehicle has been parked for at
