e. Remove the reservoir cap again and

look at the fluid level. If the fluid is

cold, the lever should be in the “COLD”

range on the dipstick. Similarly, if it is

hot, the fluid level should be in the

“HOT” range. If the level is at the low

side of either range, add automatic

transmission fluid DEXRONrII or III to

bring the level within the range.

Keep your tire inflation pressures

at the proper level.

D Always use a tire pressure

gauge. The appearance of a tire

can be misleading. Besides, tire

inflation pressures that are even

just a few pounds off can degrade

ride and handling.

D Take special care when adding

air to the compact spare tire.

The smaller tire size can gain

pressure very quickly. Add com-

pressed air in small quantities and

check the pressure often until it

reaches the specified pressure.

D Do not bleed or reduce tire

inflation pressure after driving.

It is normal for the tire inflation

pressure to be higher after driving.

D Never exceed the vehicle capac-

ity weight. Passenger and lug-

gage weight should be located so

that the vehicle is balanced.

Tire pressure gauge

The recommended cold tire inflation

pressures, tire sizes and the com-

bined weight of occupants and cargo

(vehicle capacity weight) are de-

scribed on page 214 and 217. They

are also described on the tire and

loading information label as shown.

You should check the tire inflation

pressures every two weeks, or at

least once a month. And do not forget

the spare!

INSPECTION AND ADJUSTMENT

PROCEDURE

1. Remove the tire valve cap.

2. Press the tip of the tire pressure

gauge to the tire valve.

3. Read the pressure using the grad-

uations of the gauge.

4. In case the tire inflation pressure

is not within the prescribed range,

insert the compressed air from the

valve. In case of applying too

much air, press the center of the

valve and release the air to adjust.

The following instructions for

checking tire inflation pressure

should be observed:

D The

pressure

should

be

checked only when the tires are

cold. If your vehicle has been

parked for at least 3 hours and has

not been driven for more than 1.5

km or 1 mile since, you will get

an accurate cold tire inflation pres-

sure reading.

5. After completing the tire inflation

pressure measurement and ad-

justment, apply soapy water to the

valve and check for leakage.

CAUTION

High tire pressure (overinfla-

tion)—

Keep your tires properly inflated.

Otherwise, the following condi-

tions may occur and cause an ac-

cident resulting in death or seri-

ous injuries.

Low tire pressure (underinfla-

tion)—

D Poor handling

D Excessive wear

D Uneven wear

6. Install the tire valve cap.

If a gauge and air pump are not avail-

able, have your vehicle checked by

your Toyota dealer.

D A greater possibility of tire

damage from road hazards

CAUTION

D Excessive wear

D Uneven wear

D Poor handling

Be sure to reinstall the tire valve

caps. Without the valve caps, dirt

or moisture could get into the

valve core and cause air leakage.

If the caps have been lost, have

new ones put on as soon as pos-

sible.

D Possibility of blowouts from an

overheated tire

D Poor sealing of the tire bead

D Wheel deformation and/or tire

separation

Incorrect tire inflation pressure may

waste fuel, reduce the comfort of driv-

ing, reduce tire life and make your ve-

hicle less safe to drive.

D A greater possibility of tire

damage from road hazards

If a tire frequently needs refilling,

have it checked by your Toyota deal-

er.

Checking and replacing tires

The tires on your Toyota have built−in

tread wear indicators to help you

know when the tires need replace-

ment. When the tread depth wears to

1.6 mm (0.06 in.) or less, the indica-

tors will appear. If you can see the

indicators in two or more adjacent

grooves, the tire should be replaced.

The lower the tread, the higher the

risk of skidding.

The effectiveness of snow tires is

lost if the tread wears down below

4 mm (0.16 in.).

If you have tire damage such as

cuts, splits, cracks deep enough to

expose the fabric, or bulges indi-

cating internal damage, the tire

should be replaced.

If air loss occurs while driving, do not

continue driving. Driving even a short

distance can damage a tire beyond

repair.

Any tires which are over 6 years

old must be checked by a qualified

technician even if damage is not

obvious.

Tires deteriorate with age even if they

have never or seldom been used.

This applies also to the spare tire and

tires stored for future use.

Tread wear indicator

CHECKING YOUR TIRES

REPLACING YOUR TIRES

Check the tire’s tread for tread

wear indicators. If the indicators

show, replace the tires. The loca-

tion of tread wear indicators is

shown by the “TWI” or “∆” marks,

etc., molded on the sidewall of

each tire.

When replacing a tire, use a tire of

the same size and construction,

and the same or greater maximum

load as the originally installed

tires.

Using any other size or type of tire

may seriously affect handling, ride,

speedometer/odometer calibration,

ground clearance, and clearance be-

tween the body and tires or snow

chains.

If a tire often goes flat or cannot be

properly repaired due to the size or

location of a cut or other damage, it

should be replaced. If you are not

sure, consult with your Toyota dealer.

194

2005 ECHO HATCHBACK from Jul. ’04Prod. (OM52624U)

04 04.06

Check that the maximum load of the

replaced 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. As for the

maximum load of the tire, see the load

limit at maximum cold tire inflation

pressure mentioned on the sidewall

of the tire, and as for the Gross Axle

Weight Ratings (GAWR), see the Cer-

tification Label. For details about the

sidewall of the tire and the Certifica-

tion Label, see pages 108 and 106.

An unbalanced wheel may affect ve-

hicle handling and tire life. Wheels

can get out of balance with regular

use and should therefore be balanced

occasionally.

When replacing a tubeless tire, the

air valve should also be replaced

with a new one.

CAUTION

Observe the following instruc-

tions. Otherwise, an accident

may occur resulting in death or

serious injuries.

D Do not mix radial, bias belted,

or bias−ply tires on your ve-

hicle, as this may cause dan-

gerous handling characteris-

tics resulting in loss of control.

D Do not use tires other than the

manufacturer’s recommended

size, as this may cause danger-

ous handling characteristics

resulting in loss of control.

Toyota recommends all four tires,

or at least both of the front or rear

tires be replaced at a time as a set.

See “If you have a flat tire” in Section

4 for tire change procedure.

When a tire is replaced, the wheel

should always be balanced.

Installing snow tires and

chains

Rotating tires

WHEN TO USE SNOW TIRES OR

CHAINS

When rotating tires, check for uneven

wear and damage. Abnormal wear is

usually caused by incorrect tire pres-

sure, improper wheel alignment, out−

of−balance wheels, or severe braking.

Snow tires or chains are recommended

when driving on snow or ice.

On wet or dry roads, conventional tires

provide better traction than snow tires.

SH72001

CAUTION

SNOW TIRE SELECTION

If you need snow tires, select tires of

the same size, construction and load

capacity as the originally installed tires.

Do not include a compact spare

tire when rotating the tires. It is

designed for temporary use only.

Do not use tires other than those men-

tioned above. Do not install studded tires

without first checking local regulations for

possible restrictions.

To equalize the wear and help ex-

tend tire life, Toyota recommends

that you rotate your tires accord-

ing to the maintenance schedule.

(For scheduled maintenance infor-

mation, please refer to the “Sched-

uled Maintenance Guide” or “Own-

er’s

Manual

Supplement”.).

Do not use snow tires other than the

manufacturer’s recommended size, as

this may cause dangerous handling

characteristics resulting in loss of

control.

However, the most appropriate tim-

ing for tire rotation may vary ac-

cording to your driving habits and

road surface conditions.

See “If you have a flat tire” in Section

4 for tire change procedure.

SNOW TIRE INSTALLATION

TIRE CHAIN SELECTION

CAUTION

Snow tires should be installed on all

wheels.

Use the tire chains of correct size and

type.

D Do not exceed 50 km/h (30 mph) or

the chain manufacturer’s recom-

mended speed limit, whichever is

lower.

Installing snow tires on the front wheels

only can lead to an excessive difference

in road grip capability between the front

and rear tires which could cause loss of

vehicle control.

Use SAE Class “S” type radial tire chains

except radial cable chains or V−bar type

chains.

Regulations regarding the use of tire

chains vary according to location or

type of road, so always check local reg-

ulations before installing chains.

D Drive carefully avoiding bumps,

holes, and sharp turns, which may

cause the vehicle to bounce.

When storing removed tires you should

store them in a cool dry place.

D Avoid sharp turns or locked−wheel

braking, as use of chains may ad-

versely affect vehicle handling.

Mark the direction of rotation and be sure

to install them in the same direction when

replacing.

CHAIN INSTALLATION

Install the chains on the front tires as

tightly as possible. Do not use tire

chains on the rear tires. Retighten

If wheel covers are used, they will be

scratched by the chain band, so remove

the covers before putting on the chains.

Do not attempt to use a tire chain on

the compact spare tire, as it may re-

sult in damage to the vehicle as well

as the tire.

Replacing wheels

Aluminum wheel precautions

WHEN TO REPLACE YOUR WHEELS

Replacement with used wheels is not rec-

ommended as they may have been sub-

jected to rough treatment or high mileage

and could fail without warning. Also, bent

wheels which have been straightened may

have structural damage and therefore

should not be used. Never use an inner

tube in a leaking wheel which is designed

for a tubeless tire.

D When installing aluminum wheels,

check that the wheel nuts are tight

after driving your vehicle the first 1600

km (1000 miles).

If you have wheel damage such as

bending, cracks or heavy corrosion, the

wheel should be replaced.

D If you have rotated, repaired, or

changed your tires, check that the

wheel nuts are still tight after driving

1600 km (1000 miles).

If you fail to replace a damaged wheel,

the tire may slip off the wheel or they

may cause loss of handling control.

WHEEL SELECTION

D When using tire chains, be careful not

When replacing wheels, care should be

taken to ensure that the wheels are re-

placed by ones with the same load ca-

pacity, diameter, rim width, and offset.

to damage the aluminum wheels.

CAUTION

D Use only Toyota wheel nuts and

wrench designed for your aluminum

wheels.

Observe the following instructions.

Otherwise, an accident may occur re-

sulting in death or serious injuries.

This must be observed on compact spare

tires, too.

D When balancing your wheels, use only

Toyota balance weights or equivalent

and a plastic or rubber hammer.

Do not use wheels other than the

manufacturer’s recommended size, as

this may cause dangerous handling

characteristics resulting in loss of

control.

Correct replacement wheels are available

at your Toyota dealer.

D As with any wheel, periodically check

your aluminum wheels for damage. If

damaged, replace immediately.

A wheel of a different size or type may

adversely affect handling, wheel and bear-

ing life, brake cooling, speedometer/odom-

eter calibration, stopping ability, headlight

aim, bumper height, vehicle ground clear-

ance, and tire or snow chain clearance to

the body and chassis.
