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

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

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.

■

Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 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 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. 331)

■

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

■

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor-
dance with the conditions under which it was initialized. For this reason,
the system may give a warning even if the tire pressure 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.

●

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 Equip-

ment) tire.

• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are 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

wheels or wheel housings.

• If the tire inflation pressure is extremely higher than the specified

level.

• If the spare tire is in a location subject to poor radio wave signal

reception.

• If a large metallic object which can interfere with signal reception is

put near the spare tire.

• If tires not equipped with the tire pressure warning valves and trans-

mitters 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 facility 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.

■

The initialization operation

●

Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.

●

If you have accidentally turned the engine switch off during initialization,
it is not necessary to press the reset switch again as initialization will
restart automatically when the engine switch has been turned to IGNI-
TION ON mode for the next time.

●

If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.

●

While the position of each tire is being determined and the inflation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning light will come
on.

■

When initialization of the tire pressure warning system has failed

●

Do not move the vehicle backward during initialization. Initialization is
started again from the beginning and it may take longer than usual.

●

Initialization may take longer to complete if the vehicle is driven on an
unpaved road.
When performing initialization, drive on a paved road if possible.
Depending on the driving environment and condition of the tires, initial-
ization will be completed in approximately 10 to 30 minutes.

• If initialization is not complete after driving approximately 30 minutes,

continue driving for a while.

• If initialization is not complete after driving approximately 1 hour, park

the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left and right turns) at approximately 25 mph
(40 km/h) or more

for approximately 10 to 30 minutes.

• If initialization is still not complete, have the vehicle inspected by your

Toyota dealer.

: Except when making a left/right turn

●

In the following situations, the tire inflation pressure will not be recorded
and the system will not operate properly. Perform initialization again.

• When operating the tire pressure warning reset switch, the tire pres-

sure warning light does not blink 3 times.

• After performing initialization, the tire pressure warning light blinks for

1 minute then stays on after driving for about 20 minutes.

■

Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.

■

Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:

●

Reduced fuel economy

●

Reduced driving comfort and poor handling

●

Reduced tire life due to wear

●

Reduced safety

●

Damage to the drive train

If a tire needs frequent inflating, have it checked by your Toyota dealer.

Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following:

●

Check only when the tires are cold.

If your vehicle has been parked for at least 3 hours or has not been

driven for more than 1 mile or 1.5 km, you will get an accurate cold tire

inflation pressure reading.

●

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly inflated based only on its appear-

ance.

●

It is normal for the tire inflation pressure to be higher after driving as

heat is generated in the tire. Do not reduce tire inflation pressure after

driving.

●

Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is

balanced.

WARNING

■

Proper inflation is critical to save tire performance

Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur

which could lead to an accident resulting in death or serious injury:

●

Excessive wear

●

Uneven wear

●

Poor handling

●

Possibility of blowouts resulting from overheated tires

●

Air leaking from between tire and wheel

●

Wheel deformation and/or tire damage

●

Greater possibility of tire damage while driving (due to road hazards,

expansion joints, sharp edges in the road, etc.)

NOTICE

■

When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or moisture may get into the valve and

cause an air leak, resulting in decreased tire inflation pressure.

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset

Replacement wheels are available at your Toyota dealer.

Conventionally referred to as “offset”.

Toyota does not recommend using the following:

●

Wheels of different sizes or types

●

Used wheels

●

Bent wheels that have been straightened

●

Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.

●

When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).

●

Be careful not to damage the aluminum wheels when using tire
chains.

●

Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.

Wheels

If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning

valves and transmitters that allow the tire pressure warning system to

provide advance warning in the event of a loss in tire inflation pressure.

Whenever wheels are replaced, tire pressure warning valves and trans-

mitters must be installed. (



P. 430)

WARNING

■

When replacing wheels

●

Do not use wheels that are a different size from those recommended in

the Owner’s Manual, as this may result in a loss of handling control.

●

Never use an inner tube in a leaking wheel which is designed for a

tubeless tire. Doing so may result in an accident, causing death or seri-

ous injury.

■

When installing the wheel nuts

Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, lead-

ing to bolt or disc wheel damage. In addition, the oil or grease can cause the

wheel nuts to loosen and the wheel may fall off, causing an accident and

resulting in death or serious injury. Remove any oil or grease from the wheel

bolts or wheel nuts.

NOTICE

■

Replacing tire pressure warning valves and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-

ing valves and transmitters, make sure to have tires serviced by your

Toyota dealer or other qualified service shop. In addition, make sure to

purchase your tire pressure warning valves and transmitters at your

Toyota dealer.

●

Ensure that only genuine Toyota wheels are used on your vehicle.

Tire pressure warning valves and transmitters may not work properly

with non-genuine wheels.
