WARNING

The engine compartment contains

many mechanisms and fluids that

may move suddenly, become hot,

or become electrically energized.

To avoid death or serious injury,

observe the following precautions.

■

When working on the engine

compartment

●

Keep hands, clothing and tools

away from the moving fan and

engine drive belt.

●

Be careful not to touch the

engine, radiator, exhaust mani-

fold, etc. right after driving as

they may be hot. Oil and other

fluids may also be hot.

Items

Parts and tools

●

Do not leave anything that may

burn easily, such as paper and

rags, in the engine compart-

ment.

●

Do not smoke, cause sparks or

expose an open flame to fuel or

the battery. Fuel and battery

fumes are flammable.

●

Be extremely cautious when

working on the battery. It con-

tains poisonous and corrosive

sulfuric acid.

■

When working near the elec-

tric cooling fan or radiator

grille

Be sure the engine switch is OFF.

With the engine switch in ON, the

electric cooling fan may automati-

cally start to run if the air condi-

tioning is on and/or the coolant

temperature is high. (



P.301)

■

Safety glasses

Wear safety glasses to prevent

flying or falling material, fluid

spray, etc. from getting in your

eyes.

NOTICE

■

If you remove the air cleaner

filter

Driving with the air cleaner filter

removed may cause excessive

engine wear due to dirt in the air.

which may result in death or seri-

ous injury.

■

After installing the support

rod into the slot

Make sure the rod supports the

hood securely preventing it from

falling down onto your head or

body.

Engine oil consumption

A certain amount of engine oil will

be consumed while driving. In the

following situations, oil consump-

tion may increase, and engine oil

may need to be refilled in between

oil maintenance intervals.

●

When the engine is new, for

example directly after purchasing

the vehicle or after replacing the

engine

●

If low quality oil or oil of an inap-

propriate viscosity is used

●

When driving at high engine

speeds or with a heavy load, or

when driving while accelerating or

decelerating frequently

●

When leaving the engine idling for

a long time, or when driving fre-

quently through heavy traffic

■

Engine oil level rise

If the vehicle is repeatedly driven

without the engine warmed up,

moisture caused by dew condensa-

tion inside the engine or fuel which

did not burn mixes into the engine

oil, resulting in a rise in engine oil

level. However, this is not a mal-

function. For example, the engine

become difficult to be warmed up in

the following situations.

●

When driving a short distance

●

When driving at a low speed

●

When the outside temperature is

low

When checking the engine oil, make

sure that the engine is warmed up. If

the engine oil level exceeds the refill

upper limit mark, contact your Toy-

ota dealer.

■

When to replace your vehicle’s
tires

Tires should be replaced if:

●

The treadwear indicators are
showing on a tire

●

You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage

●

A tire goes flat repeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage

If you are not sure, consult with your
Toyota dealer.

■

Tire life

Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.

■

Low profile tires (18-inch tires)

Generally, low profile tires will wear
more rapidly and tire grip perfor-
mance will be reduced on snowy
and/or icy roads when compared to
standard tires. Be sure to use snow
tires or tire chains on snowy and/or
icy roads and drive carefully at a
speed appropriate for road and
weather conditions.

■

Maximum load of tire

Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whichever is greater.

For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation pressure mentioned on
the sidewall of the tire. (

■

Tire types

●

Summer tires

Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performance as snow tires,
summer tires are inadequate for
driving on snow-covered or icy
roads. For driving on snow-covered
roads or icy roads, the use of snow
tires is recommended. When install-
ing snow tires, be sure to replace all
four tires.

●

All season tires

All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions as well as for use
year-round. All season tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.

●

Snow tires

For driving on snow-covered roads
or icy roads, we recommend using
snow tires. If you need snow tires,
select tires of the same size, con-
struction and load capacity as the
originally installed tires. Since your
vehicle has radial tires as original
equipment, make sure your snow

tires also have radial construction.

Do not install studded tires without

first checking local regulations for

possible restrictions. Snow tires

should be installed on all wheels.

(



P.247)

■

If the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

■

Checking the tire valves

When replacing the tires, check the

tire valves for deformation, cracks,

and other damage.

Rotate the tires in the order

shown.

WARNING

■

When inspecting or replacing

tires

Observe the following precautions

to prevent accidents.

Failure to do so may cause dam-

age to parts of the drive train as

well as dangerous handling char-

acteristics, which may lead to an

accident resulting in death or seri-

ous injury.

●

Do not mix tires of different

makes, models or tread pat-

terns.

Also, do not mix tires of remark-

ably different treadwear.

●

Do not use tire sizes other than

those recommended by Toyota.

●

Do not mix differently con-

structed tires (radial, bias-belted

or bias-ply tires).

●

Do not mix summer, all season

and snow tires.

●

Do not use tires that have been

used on another vehicle.

Do not use tires if you do not

know how they were used previ-

ously.

NOTICE

■

Low profile tires (18-inch

tires)

Low profile tires may cause

greater damage than usual to the

tire wheel when sustaining impact

from the road surface. Therefore,

pay attention to the following:

●

Be sure to use proper tire infla-

tion pressure. If tires are

under-inflated, they may be

damaged more severely.

●

Avoid potholes, uneven pave-

ment, curbs and other road haz-

ards. Failure to do so may lead

to severe tire and wheel dam-

age.

■

If tire inflation pressure of

each tire becomes low while

driving

Do not continue driving, or your

tires and/or wheels may be

ruined.

■

Driving on rough roads

Take particular care when driving

on roads with loose surfaces or

potholes.

These conditions may cause

losses in tire inflation pressure,

reducing the cushioning ability of

the tires. In addition, driving on

rough roads may cause damage

to the tires themselves, as well as

the vehicle’s wheels and body.

Tire rotation

308

6-3. Do-it-yourself maintenance

Front

To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.

Vehicles with a tire pressure warn-
ing system: Do not fail to initialize
the tire pressure warning system
after tire rotation.

Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.

The tire pressure warning sys-
tem of this vehicle adopts a
2-type warning system.



When “Adjust Pressure” is
displayed (Normal Warning)

A warning with the tire pressure
warning light and warning buzzer
when there is an unknown level of
low tire pressure with the appear-
ance of the tire due to natural air
leakage as well as the pressure
lowering due to changes in the
pressure according to the outside

temperature. (Ways of coping:



P.354, 391)



When “Immediately Check
Tire when Safe” is displayed
(Emergency Warning)

A warning with the tire pressure
warning light and warning buzzer
when there is a known level of low
tire pressure with the appearance
of the tire due to pressure suddenly
lowering. (Ways of coping:



P.354,

364)
However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).

The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.

Routine tire inflation pressure
checks

The tire pressure warning system
does not replace routine tire inflation
pressure checks. Make sure to
check tire inflation pressure as part
of your routine of daily vehicle
checks.

■

Tire inflation pressure

●

It may take a few minutes to dis-
play the tire inflation pressure
after the engine switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.

●

Tire inflation pressure changes
with temperature.
The displayed values may also be
different from the values mea-
sured using a tire pressure gauge.

■

Situations in which the tire
pressure warning system may
not operate properly

●

In the following cases, the tire
pressure warning system may not
operate properly.

• If non-genuine Toyota wheels are

used.

• A tire has been replaced with a

tire that is not an OE (Original
Equipment) tire.

• A tire has been replaced with a

tire that is not of the specified size.

• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire

is equipped.

• If a window tint that affects the

radio wave signals is installed.

• If there is a lot of snow or ice on

the vehicle, particularly around the

310

6-3. Do-it-yourself maintenance

wheels or wheel housings.

• If the tire inflation pressure is

extremely higher than the speci-

fied level.

• If tires not equipped with tire pres-

sure warning valves and transmit-

ters are used.

• If the ID code on the tire pressure

warning valves and transmitters is

not registered in the tire pressure

warning computer.

●

Performance may be affected in

the following situations.

• Near a TV tower, electric power

plant, gas station, radio station,

large display, airport or other facil-

ity that generates strong radio

waves or electrical noise.

• When carrying a portable radio,

cellular phone, cordless phone or

other wireless communication

device.

●

When the vehicle is parked, the

time taken for the warning to start

or go off could be extended.

●

When tire inflation pressure

declines rapidly for example when

a tire has burst, the warning may

not function.

■

Warning performance of the tire

pressure warning system

The warning of the tire pressure

warning system will change in

accordance with driving conditions.

For this reason, the system may

give a warning even if the tire pres-

sure does not reach a low enough

level, or if the pressure is higher

than the pressure that was adjusted

to when the system was initialized.

When replacing tires or wheels,

tire pressure warning valves and

transmitters must also be

installed.
When new tire pressure warning

valves and transmitters are

installed, new ID codes must be

registered in the tire pressure

warning computer and the tire

pressure warning system must

be initialized. Have tire pressure

warning valves and transmitter

ID codes registered by your Toy-

ota dealer. (



P.316)

■

Replacing tires and wheels

If the ID code of the tire pressure

warning valve and transmitter is not

registered, the tire pressure warning

system will not work properly. After

driving for about 20 minutes, the tire

pressure warning light blinks for 1

minute and stays on to indicate a

system malfunction.
