Keep the back door and quarter
windows closed while driving. An
open or unsealed back door and
quarter windows may cause ex-
haust gases to be drawn into the
vehicle.
To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves,
or other obstructions.
If you smell exhaust fumes in
the vehicle, drive with the win-
dows open and the back door
closed. Have the cause immedi-
ately located and corrected.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume 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 pis-
ton 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 tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high −speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
Facts about engine oil
consumption

’01 L/C U (L/O 0008)
182
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal 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.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see ”Checking the engine oil level” in Sec-
tion 7
−2.
Your engine is fitted with iridium −tipped
spark plugs.
NOTICE
Use only iridium −tipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drivabil-
ity.

If you are a skilled do
−it−yourself
mechanic, the Toyota service manuals are
recommended. Please be aware that do −it−yourself maintenance can affect your
warranty coverage. See ”Owner ’s Warranty
Information Booklet” or ”Owner ’s Manual
Supplement” for the details. General maintenance
Listed below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any
unusual noise, smell or vibration, you
should investigate the cause or take your
vehicle to your Toyota dealer or a quali-
fied service shop immediately. It is recom-
mended that any problem you notice be
brought to the attention of your dealer or
the qualified service shop for their advice.
CAUTION
Make these checks only where ade-
quate ventilation can be obtained if
you run the engine.
OUTSIDE THE VEHICLE
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. See
Section 7
−2 for additional information. Tire surface and wheel nuts
Check the tires carefully for cuts, damage
or excessive wear. See Section 7
−2 for
additional information. When checking the
tires, make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires according to the mainte-
nance schedule. (For scheduled mainte-
nance information, please refer to the
”Scheduled Maintenance Guide” or ”Own-
er ’s Manual Supplement”.) See Section 7 −2 for additional information.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter 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 and back door oper-
ate smoothly and all latches lock securely.
Make sure the engine hood secondary
latch secures the hood from opening when
the primary latch is released.

’01 L/C U (L/O 0008)239
Brake fluid level
Make sure the brake fluid level is correct.
See Section 7
−2 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 Section 7 −2 for addi-
tional 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 Section 7 −2 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 immedi-
ately. (See engine exhaust cautions in
Section 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tip
−offs that
indicate service is needed. Some impor-
tant clues are as follows:
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 im-
mediately.)
Flat −looking tire; 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 floor; vehicle pulls to one side
when braking
Engine coolant temperature continually
higher than normal
Engine continually runs hot; oil pres-
sure gauge stays low
If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do
−it−yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Section 6,
there are still a number of items that must
be done by a qualified technician with
special tools.
For information on tools and parts for do −
it −yourself maintenance, see ”Parts and
tools”.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
CAUTION
When the engine is running,
keep hands, clothing, and tools
away from the moving fan and
engine drive belts. (Removing
rings, watches, and ties is advis-
able.)
Right after driving, the engine
compartment—the engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.—will be hot. So
be careful not to touch them. Oil,
fluids and spark plugs may also
be hot.
If the engine is hot, do not re-
move the radiator cap or loosen
the drain plugs to prevent burn-
ing yourself.
Do not smoke, cause sparks or
allow open flames around fuel or
the battery. Their fumes are flam-
mable.
Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
Warning: Battery posts, terminals
and related accessories contain
lead and lead compounds, chemi-
cals know to the State of Califor-
nia to cause cancer and repro-
ductive harm. Wash hands after
handling.
