To ensure that the three −way 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 situ-
ation.
Do not remain for a long time in
a parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an uncon-
fined area and adjust the heating
or cooling system to force out-
side air into the vehicle.

’01 L/C U (L/O 0008)181
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.
