The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.

Reservoir cap
“F” line
“L” line

If the level is on or below the “L”
line, add coolant up to the “F” line.
(

P. 531)

■

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.

For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool-

ant and 50% deionized water. (Minimum temperature: -31

F

[-35

C])

For Canada: “Toyota Super Long Life Coolant” is a mixture of 55% cool-

ant and 45% deionized water. (Minimum temperature: -44

F

[-42

C])

For more details about engine coolant, contact your Toyota dealer.

■

If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.

WARNING

■

When the engine is hot
Do not remove the engine coolant reservoir cap or the radiator cap.
(

P. 533)

The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

NOTICE

■

When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.

■

If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

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

P. 480)

◆

Installing tire pressure warning valves and transmitters

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 Toyota dealer. (

P. 443)

◆

Initializing the tire pressure warning system

■

The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When changing the tire size.
● When the tire inflation pressure is changed such as when chang-

ing traveling speed or load weight.

When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

■

How to initialize the tire pressure warning system

Park the vehicle in a safe place and turn the engine switch off.

Initialization cannot be performed while the vehicle is moving.

Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (

P. 546)

Make sure to adjust the tire pressure to the specified cold tire infla-

tion pressure level. The tire pressure warning system will operate

based on this pressure level.

Turn the engine switch to the “ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system).
Open the glove box. Press
and hold the tire pressure
warning reset switch until the
tire pressure warning light
blinks slowly 3 times.

Vehicles without a smart key system: Wait for a few minutes with
the engine switch in the “ON” position and then turn the engine
switch to the “ACC” or “LOCK” position.
Vehicles with a smart key system: Wait for a few minutes with the
engine switch in IGNITION ON mode and then turn the engine
switch off.

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota 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 cannot 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.

■

Replacing tires and wheels (vehicles with a tire pressure warning

system)
If the ID code of the tire pressure warning valve and transmitter is not reg-

istered, the tire pressure warning system will not work properly. After driv-

ing for about 20 minutes, the tire pressure warning light blinks for 1

minute and stays on to indicate a system malfunction.

■

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.

■

Routine tire inflation pressure checks (vehicles with a tire pressure

warning system)
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.

■

Low profile tires (17-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.

444

7-3. Do-it-yourself maintenance

COROLLA_TMMMS_TMMC_U

■

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.

■

Tire types

●

Summer tires
Summer tires are high-speed performance 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 provide better traction in snow and to

be adequate for driving in most winter conditions as well as for use

year-round. All season tires, however, do not have adequate traction

performance compared with snow tires in heavy or loose snow. Also, all

season tires fall short in acceleration 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. 263)

■

Initializing the tire pressure warning system (vehicles with a tire

pressure warning system)
Initialize the system with the tire inflation pressure adjusted to the speci-

fied level.

■

If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.

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. (

■

If you press the tire pressure warning reset switch accidentally (vehi-

cles with a tire pressure warning system)
If initialization is performed, adjust the tire inflation pressure to the speci-

fied level and initialize the tire pressure warning system again.

■

When initialization of the tire pressure warning system has failed

(vehicles with a tire pressure warning system)
Initialization can be completed in a few minutes. However, in the following

cases, the settings have not been recorded and the system will not oper-

ate properly. If repeated attempts to record tire inflation pressure settings

are unsuccessful, have the vehicle inspected by your Toyota dealer.

●

When operating the tire pressure warning reset switch, the tire pressure

warning light does not blink 3 times.

●

After driving for a certain period of time since the initialization has been

completed, the warning light comes on after blinking for 1 minute.

WARNING

■

When inspecting or replacing tires
Observe the following precautions to prevent accidents.

Failure to do so may cause damage to parts of the drive train as well as

dangerous handling characteristics, which may lead to an accident

resulting in death or serious injury.

●

Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

●

Do not use tire sizes other than those recommended by Toyota.

●

Do not mix differently constructed 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 previously.

■

NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valves,

transmitters and tire valve caps (vehicles with a tire pressure warn-

ing system)

●

When removing or fitting the wheels, tires or the tire pressure warning

valves and transmitters, contact your Toyota dealer as the tire pres-

sure warning valves and transmitters may be damaged if not handled

correctly.

●

When replacing tire valve caps, do not use tire valve caps other than

those specified. The cap may become stuck.

■

To avoid damage to the tire pressure warning valves and transmit-

ters (vehicles with a tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning

valve and transmitter may not operate properly. If a liquid sealant is

used, contact your Toyota dealer or other qualified service shop as soon

as possible. Make sure to replace the tire pressure warning valve and

transmitter when replacing the tire. (

P. 441)

■

Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-

holes.

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.

■

Low profile tires (17-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 inflation pressure. If tires are under-inflated,

they may be damaged more severely.

●

Avoid potholes, uneven pavement, curbs and other road hazards. Fail-

ure to do so may lead to severe tire and wheel damage.

■

If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
