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!

Keep people and combustible ma-
terials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.

Do 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:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel
could cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good run-
ning order. Malfunctions in the
engine electrical system, elec-
tronic ignition system/distributor
ignition system or fuel system
could cause an extremely 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 catalyt-
ic converter system best.
To ensure that the three-way cat-
alytic converter and the entire
emission control system operate
properly, your vehicle must re-
ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte-
nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.

CAUTION!

Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconscious-
ness 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 some-
thing, 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
running. If it is unavoidable, how-
ever, 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 or back door
closed while driving. An open or
unsealed trunk lid or back door
may cause exhaust gases to be
drawn into the vehicle. If you must
drive with the trunk lid or back
door open to accommodate a
large object, close the windows,
open all the instrument panel
vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control set at the OUTSIDE AIR
position.

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
other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid or back
door closed. Have the cause im-
mediately located and corrected.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine, and plays a major role in maintaining
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 piston
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 com-
bustion 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.
Facts about engine oil
consumption Engine exhaust cautions
ProCarManuals.com

133 The amount of engine oil consumed
depends 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 be-
come diluted and make it difficult to
judge the true level accurately.
As an example, if a vehicle is used for re-
peated 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 di-
luted with fuel or moisture, making it ap-
pear 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 is excessively consumed
after driving at high speeds.IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in proper
vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will not be impaired. Therefore, it is essen-
tial 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 regu-
larly could lead to serious engine
trouble due to insufficient oil.
For detailed information on oil level check,
see Checking the engine oil levelº in
Chapter 7-2.
Your engine is fitted with twin ground elec-
trode spark plugs.
NOTICE
Use only twin ground electrode
spark plugs for your engine perfor-
mance.

134TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other will still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
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
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stopsÐbut no
more!
CAUTION!

Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re-
serve.

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than
normal. And your braking distance
will be longer.
ANTI-LOCK BRAKE SYSTEM (with
ABSº warning light)
The anti-lock brake system is designed to
prevent lock-up of the wheels during sud-
den braking or braking on slippery road
surfaces. This assists the driver in con-
trolling the vehicle under these circum-
stances.
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).
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.
When the anti-lock brake system function
is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system
work for you, just hold the brake pedal
down more firmly. Do not pump the brake.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 vehicle:

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 ve-
hicles 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.

ABSº warning light
The light comes on when the ignition key
is turned to the ONº position. After about
3 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.Even if the anti-lock brake system should
fail, the brake system will still operate con-
ventionally. Have your vehicle checked by
your Toyota dealer as soon as possible.
DRUM-IN-DISC TYPE PARKING
BRAKE SYSTEM (all 1MZ-FE engined
vehicles, and some 5S-FE engined ve-
hicles with anti-lock brake system)
Your vehicle has a drum-in-disc type
parking brake system. This type of brake
system needs bedding-down of the brake
shoes periodically or whenever the park-
ing brake shoes and/or drums are re-
placed.
Have your Toyota dealer perform the bed-
ding-down.The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to
where replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

136When stowing luggage or cargo in the ve-
hicle, observe the following:

Put luggage or cargo in the trunk or
luggage compartment when at all pos-
sible. Be sure all items are secured in
place.

Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
this.

For better fuel economy, do not carry
unneeded weight.
CAUTION!

To prevent luggage or packages
from sliding forward during brak-
ing, do not stack anything in the
enlarged trunk room or the lug-
gage compartment higher than
the seatbacks. Keep luggage or
packages low, as close to the floor
as possible.

Never allow anyone to ride in the
enlarged trunk room or the lug-
gage compartment. It is not de-
signed for passengers. They
should ride in their seats with their
seat belts properly fastened.
Otherwise, they are much more
likely to suffer serious bodily inju-
ry, in the event of sudden braking
or a collision.

Do not place anything on the filler
panel behind the rear seatback or
luggage cover. Such items may be
thrown about and possibly injure
people in the vehicle during sud-
den braking or an accident.

Do not drive with objects left on
top of the instrument panel. They
may interfere with the driver's field
of view. Or they may move during
sharp vehicle acceleration or turn-
ing, and impair the driver's control
of the vehicle. In an accident they
may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond the
vehicle capacity weight specified in
Part 8.
The vehicle identification number
(VIN) is the legal identifier for your ve-
hicle. This number is on the left top of
the instrument panel, and can be seen
through the windshield from outside.
The vehicle identification number (VIN) is
also on the Certification Label.
This is the primary identification number
for your Toyota. It is used in registering the
ownership of your vehicle.

138Your new vehicle carries theft preven-
tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce
the incidence of vehicle thefts by facilitat-
ing the tracing and recovery of parts from
stolen vehicles. The label is designed so
that once it is applied to a surface, any at-
tempt to remove it will result in destroying
the integrity of the label. Transferring
these labels intact from one part to anoth-
er, will be impossible.
NOTICE
You should not attempt to remove
the theft prevention labels as it may
violate certain state or federal laws.
Make sure what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires
Summer tires are high-speed capability
tires best suited to highway driving under
dry conditions.
Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recom-
mend using snow tires. If installing snow
tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have ad-
equate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance compared
with summer tires in highway driving.
CAUTION!
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of control.
