It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol 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 ve-
hicle overheats” on page 255.
Engine oil pressure gauge
Idling
Normal
driving
The engine oil pressure gauge indicates
engine oil pressure when the ignition
switch is on. Check it while driving to
make sure the needle is in the proper
range.
If the engine oil pressure should stay be-
low the normal range, pull off the road to
a safe place and stop the engine immedi-
ately. Call a Toyota 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 oil level, and the engine oil
level must be checked using the level
dipstick. It is not a malfunction even if the needle
of the engine oil pressure gauge returns
to “L” when the ignition switch is turned
to the “START” position.
NOTICE
Do not drive the vehicle with the en-
gine oil pressure below the normal
range until the cause is fixed—it may
ruin the engine.

To ensure that the threeway cata-
lytic converter and the entire emis-
sion control system operate proper-
ly, your vehicle must receive the
periodic inspections required by the
Toyota Maintenance Schedule. For
scheduled maintenance information,
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.
Engine exhaust cautions
CAUTION
Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and
odorless gas. It can cause un-
consciousness or even death.
Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a
change in the sound of the ex-
haust, have the system checked
immediately.
Do not run the engine in a ga-
rage or enclosed area except for
the time needed to drive the ve-
hicle in or out. The exhaust
gases cannot escape, making
this a particularly dangerous sit-
uation.
Do not remain for a long time in
a parked vehicle with the engine
running. If it is unavoidable,
however, do so only in an un-
confined area and adjust the
heating or cooling system to
force outside air into the vehicle.

212
2004 L/C100 from Aug ’03 Prod. (OM60A04U)
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.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 Imp.qt/600
miles)
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.

Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W−30. “Energy −
Conserving” shown in the lower portion,
indicates that the oil has fuel −saving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
To ensure excellent lubrication perfor-
mance for your engine, “Toyota Genuine
Motor Oil” is available, which has been
specifically tested and approved for all
Toyota engines.
Please contact your Toyota dealer for fur-
ther details about “Toyota Genuine Motor
Oil”. Look at the seethrough coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the “FULL” and “LOW” lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the “LOW” line, add
coolant. Bring the level up to the “FULL”
line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.

Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non −amine, non− nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology consists of the combination of
low phosphates and organic acids.)
“Toyota Super Long Life Coolant” is pre-
mixed with 50% coolant and 50% deion-
ized water. This coolant provides protec-
tion down to about –35 °C (–31 °F).
NOTICE
Do not use plain water alone.
Toyota recommends “Toyota Super Long
Life Coolant” which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your engine cool-
ant system with proper usage. “Toyota Su-
per Long Life Coolant” is formulated with
long− life hybrid organic acid technology
and has been specifically designed to
avoid engine cooling system malfunction
on Toyota vehicles.
Please contact your Toyota dealer for fur-
ther details. If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Toyota dealer.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator or con-
denser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.

Regulations regarding the use of tire
chains vary according to location or
type of road, so always check the local
regulations before installing chains.
NOTICE
If the wrong combination of tire and
chain is used, the chains could dam-
age the vehicle body.
CHAIN INSTALLATION
Install the chains on the rear tires as
tightly as possible. Do not use tire
chains on the front tires. Retighten
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.
CAUTION
Do not exceed 50 km/h (30 mph)
or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which
may cause the vehicle to
bounce.
Avoid sharp turns or locked
wheel braking, as use of chains
may adversely affect vehicle han-
dling.
When driving with chains
installed, be sure to drive care-
fully. Slow down before entering
curves to avoid losing control of
the vehicle. Otherwise an acci-
dent may occur.
Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
