Fuel pump shut off system

Operation in foreign countries

Three−way catalytic converter

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 the ignition

switch to “ACC” or “LOCK” once and start

it.

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 (unleaded and minimum octane

number).

CAUTION

Inspect the ground under the vehicle

before restarting the engine. If you

find that liquid has leaked onto the

ground, it is the fuel system has

been damaged and it is in need of

repair. In this case, do not restart the

engine.

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

D Keep people and combustible mate-

rials away from the exhaust pipe

while the engine is running. The

exhaust gas is very hot.

D Do not drive, idle or park your ve-

hicle over anything that might burn

easily such as grass, leaves, paper

or rags.

Engine exhaust cautions

NOTICE

z If the engine becomes difficult to

start or stalls frequently, take your

vehicle in for a check−up as pos-

sible. Remember, your Toyota dealer

knows your vehicle and its three−

way catalytic converter system best.

CAUTION

large amount of unburned gases

D Avoid inhaling the engine exhaust.

It contains carbon monoxide, which

is a colorless and odorless gas. It

can cause unconsciousness or even

death.

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:

z 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”.

D 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.

z Use only unleaded gasoline.

z Do 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.

z Do not allow the engine to run at

idle speed for more than 20 min-

utes.

D 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.

z Avoid racing the engine.

z Do not push−start or pull−start your

vehicle.

D 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.

z Do not turn off the ignition while

the vehicle is moving.

z 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.

Facts about engine oil

consumption

FUNCTIONS OF ENGINE OIL

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.

D Keep the back door closed while

driving. An open or unsealed back

door may cause exhaust gases to

be drawn into the vehicle.

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.

More oil is consumed by high−speed driv-

ing and frequent acceleration and decel-

eration.

D 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.

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.

A new engine consumes more oil, since

its pistons, piston rings and cylinder walls

have not become conditioned.

D If you smell exhaust fumes in the

vehicle, drive with the windows

open and the back door closed.

Have the cause immediately located

and corrected.

Oil consumption: Max. 1.0 L per 1000

km (1.1 qt./600 miles, 0.9 lmp. qt./600

miles)

D 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.

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.

D 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 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.
