OCTANE RATING
5S±FE engine: Select Octane Rating 87
(Research Octane Number 91) or higher.
1MZ±FE engine: Select Octane Rating
87 (Research Octane Number 91) or
higher. For improved vehicle perfor-
mance, the use of premium unleaded
gasoline with an Octane Rating 91 (Re-
search Octane Number of 96) or higher
is recommended.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no
cause for concern.GASOLINES CONTAINING DETERGENT
ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build±up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
IMPROVED GASOLINES
The American Automobile Manufacturers
Association (AAMA) has developed a
specification of improved gasolines. The
AAMA specification offers optimal fuel
information for better vehicle perfor-
mance and better protection of your en-
gine.
Toyota recommends the use of gasolines
that meet the AAMA specification, if avail-
able, for improved driveability and emis-
sion control system.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary±Butyl Ether) are available in the
market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.GASOLINES CONTAINING MMT
Some gasolines contain an octane±en-
hancing additive called MMT (methylcy-
clopentadienyl manganese tricarbonyl).
Toyota does not recommend the use of
gasolines that contain MMT. If fuels con-
taining MMT are used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Toyota dealer for ser-
vice.
GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota, be
sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.

Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high three±way catalytic
converter temperature.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check±up as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
three±way catalytic converter sys-
tem best.
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 separate ºScheduled
Maintenance Guideº or ºOwner's
Manual Supplementº.
Engine exhaust cautions
CAUTION
Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
Keep the trunk lid closed while
driving. An open or unsealed trunk
lid may cause exhaust 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 wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed. Have
the cause immediately 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.
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 express way, 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 ºChecking the engine oil levelº in
Chapter 7±2.

You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti±lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ºABSº brake
pedal:
When the anti±lock brake system func-
tion is in action, you may feel the brake
pedal pulsating and hear a noise. In this
situation, to let the anti±lock brake sys-
tem work for you, just hold the brake
pedal down more firmly. Do not pump
the brake in a panic stop. Pumping the
brake pedal makes the stopping distance
longer.
The brake pedal pulsation caused by the
anti±lock brake system may indicate haz-
ardous road surface conditions. Although
the anti±lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti±lock brake system cannot overcome
the laws of physics that act on your ve-
hicle:
Braking capability is dependent on tire
friction with the road surface.
Even though the anti±lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti±lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti±lock brake
system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snow±cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
ºABSº warning light
The light comes on when the ignition key
is turned to the ºONº position. After a few
seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on as de-
scribed above, or remains on.
The light comes on while driving.
