er fuels is not covered under Toyota’s new
vehicle warranty.
NOTICE
zDo not use improper fuels. If im-
proper fuels are used the engine
will be damaged.
zDo not use leaded gasoline on your
vehicle. Use of leaded gasoline will
cause damage to the engine. Also,
this can increase maintenance
costs.
zEU area: Bioethanol fuel sold under
names such as “E50” or “E85” and
fuel containing a large amount of
ethanol should not be used. The
use of these fuels will damage the
vehicle’s fuel system. In case of
any doubt, ask any authorized
Toyota dealer or repairer, or
another duly qualified and equipped
professional.
zExcept EU area: Bioethanol fuel
sold under names such as “E50” or
“E85” and fuel containing a large
amount of ethanol should not be
used. Your vehicle can use gasoline
mixed with 10% max ethanol. The
use of fuel with more than 10%
ethanol content (E10) will damage
the vehicle’s fuel system. You must
ensure that refueling is carried out
only from a source where fuel spec-
ification and quality can be guaran-
teed. In case of any doubt, ask any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.

unleaded gasoline with a Research Oc-
tane Number of 95 or higher.
Except EU area:
Your vehicle must use only unleaded
gasoline.
For optimum engine performance, select
unleaded gasoline with a Research Oc-
tane Number of 95 or higher.
To help prevent gas station mix−ups, your
vehicle has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.OCTANE/CETANE NUMBER
Select Research Octane Number 95 or
higher.
Use of fuel with an octane or cetane num-
ber lower than stated will cause persistent
heavy knocking. If severe, this will lead to
engine damage.
USE OF ETHANOL BLENDED GASOLINE
IN A GASOLINE ENGINE
Toyota allows the use of ethanol blended
gasoline where the ethanol content is up
to 10%. Make sure that the ethanol
blended gasoline to be used has a Re-
search Octane Number that follows the
above.
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 any
authorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.

196INFORMATION BEFORE DRIVING YOUR TOYOTA
The fuel pump shut off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the engine after the fuel pump shut
off system activates, turn theengine
switch to “ACC” or “LOCK” once and start
it.
CAUTION
Inspect the ground under the vehicle
before restarting the engine. If you
find that fuel has leaked onto the
ground, the fuel system has been
damaged and is in need of repair. In
this case, do not restart the engine.
Operation in foreign countries
If you plan to drive your Toyota in
another country...
First,comply with the vehicle registration
laws.
Second,confirm the availability of the cor-
rect fuel.

Fuel pump shut off system

INFORMATION BEFORE DRIVING YOUR TOYOTA197
The three−way catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
DKeep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
DDo not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases
flowing into the three−way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
zUse only unleaded gasoline.
zDo not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three−
way catalytic converter.
zDo not allow the engine to run at
idle speed for more than 20 min-
utes.
zAvoid racing the engine.
zDo not push−start or pull−start your
vehicle.
zDo not turn off the engine while the
vehicle is moving.
zKeep 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.
zIf the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check−up to any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.
zTo ensure that the three−way
catalytic converter and the entire
emission control system operate
properly, your vehicle must receive
the periodic inspections required by
the Toyota Maintenance Schedule.
For scheduled maintenance
information, refer to the “Toyota
Service Booklet” or “Toyota
Warranty Booklet”.

Engine exhaust cautions
CAUTION
DExhaust gases include harmful car-
bon monoxide (CO) that is colorless
and odorless. Inhaling exhaust
gases may lead to death or a seri-
ous health hazard.
DThe exhaust should be checked oc-
casionally. If there is a hole or
crack caused by corrosion, damage
to a joint or abnormal exhaust
noise, be sure to have the vehicle
inspected and repaired by any au-
thorized Toyota dealer or repairer,
or another duly qualified and
equipped professional. Failure to do
so may allow exhaust gases to en-
ter the vehicle, resulting in death or
a serious health hazard.
DIf the vehicle is in a poorly venti-
lated area, turn the engine off. In a
closed area, such as a garage, ex-
haust gases may collect and enter
the vehicle. This may lead to death
or a serious health hazard.
DDo 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.
DKeep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle.
DTo allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, and
other obstructions.
DIf the smell of exhaust is noticed
inside the vehicle, open the win-
dows. Large amounts of exhaust in
the vehicle can cause driver drowsi-
ness and an accident, resulting in
death or a serious health hazard.
Have the vehicle inspected by any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional immediately.
DDo not leave the engine running in
an area with snow build−up, or
where it is snowing. If snowbanks
build up around the vehicle while
the engine is running, exhaust
gases may collect and enter the ve-
hicle. This may lead to death or a
serious health hazard.
DWhen taking a nap in the vehicle,
always turn the engine off. Other-
wise, you may accidentally move
the shift lever or depress the accel-
erator pedal, which could cause an
accident or fire due to engine over-
heating. Additionally, if the vehicle
is parked in a poorly ventilated
area, exhaust gases may collect and
enter the vehicle, leading to death
or a serious health hazard.

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.
DOil 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.
DOil 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 qts./600 miles, 0.9 lmp.qts./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.
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 has been excessively con-
sumed while 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” on
page 264 in Section 7−2.

Facts about engine oil
consumption

200INFORMATION BEFORE DRIVING YOUR TOYOTA
Brake system
The tandem master cylinder brakesystem
is a hydraulic system with two separate
sub−systems. If either sub−system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power−assist the brakes. If the engine
should quit while you are driving, you can
bringthevehicletoastopwithnormal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
DDo not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up the reserved vacuum.
DEven if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTI−LOCK BRAKE SYSTEM
The anti−lock brake system is designed
to help prevent lock−up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS 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. This will re-
sult in reduced braking performance.
The anti−lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti−lock brake sys-
tem.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle begins to move. This means
that the anti−lock brake system is in self−
check mode, and does not indicate a mal-
function.
When the anti−lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
