Your vehicle may overheat during severe operating conditions,
such as:

Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in
stop−and−go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 338.
ENGINE OIL PRESSURE GAUGE

Normal driving 2Idling
The engine oil pressure gauge indicates engine oil
pressure when the ignition is on. Check it while driving to
make sure the needle is in the proper range.
If the engine oil pressure should stay below the normal range,
pull off the road to a safe place and stop the engine
immediately. Call a Lexus dealer or qualified repair shop for
assistance.
Engine oil pressure may not build up when the engine oil level
is too low. The engine oil pressure gauge is not designed to
indicate engine oil level, and the engine oil level must be
checked using the level dipstick.

MAINTENANCE
388Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 450 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 421 for
additional information.
Engine oil level
Check the level on the dipstick with the engine turned off and
the vehicle parked on a level spot.
See page 410 for additional
information.
Suspension fluid level
Make sure the suspension fluid level is correct. See page 423
for additional information.
Power steering fluid level
Check the level through the reservoir. The level should be in
the “HOT” or “COLD” range depending on the fluid
temperature. See page 422 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or smell
exhaust fumes, have the cause located and corrected
immediately. (See “Engine exhaust caution” on page 255.)
Vehicle interior
Items listed below should be checked regularly, e.g. while
performing periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail lights, turn signal
lights, and other lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning
buzzers function properly.
Steering wheel
Check that it ha s the specified free play. Be alert for changes
in steering condition, such as hard steering, excessive free
play or strange noise.
Seats
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly. Check that the head
restraints move up and down smoothly and that the locks hold
securely in any latched position. For folding −down rear
seatbacks, swing− up rear seat cushions and detachable third
seats, check that the latches lock securely.
Seat belts
Check that the seat belt system such as buckles, retractors
and anchors operate properly and smoothly. Make sure the
belt webbing is not cut, frayed, worn or damaged.

MAINTENANCE
390
Tire rotation
Rotate the tires according to the maintenance schedule.
(For scheduled maintenance information, please refer to
the “Owner’s Manual Supplement / Scheduled
Maintenance”.) See page 437 for additional information.DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
 Engine continually runs hot; oil pressure gauge stays low.

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 by high−
speed driving and frequent
acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 lmp.qt./600 miles)
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 THE ENGINE OIL LEVEL
62X001e
With the engine at operating temperature and turned off,
check the oil level on the dipstick.
1. To get a correct reading, the vehicle should be on level
ground. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it
clean.
3. Standing up on the left side of the vehicle, reinsert the
dipstick in the direction so that the “ENGINE OIL” on top should
be read correctly and push it in as far as it will go, or the reading
will not be correct.

 1 Add oil 2O.K. 3Too full
4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the full line (
5 ) and the
low line ( 4 ), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.
