6-3. Do-it-yourself maintenance

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.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (

P. 684)

◆

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  valve  and  transmitter  ID
codes registered by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. (

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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

■

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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.

■

Replacing tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 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 check

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

■

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

The effectiveness of the tires as snow tires is lost.

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

wheels or wheel housings.

• If the tire inflation pressure is extremely higher than the specified level.
• If wheels without the tire pressure warning valves and transmitters 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 dis-

play, airport or other facility that generates strong radio waves or electri-
cal 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 pressure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.

●

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

●

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

■

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accordance
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.

■

When initialization of the tire pressure warning system has failed

Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer as soon as possible.

●

When operating the initialization of the system, the tire pressure warning
light does not flash 3 times and the setting message does not appear on the
multi-information display.

●

After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.

■

Registering ID codes

The ID codes of the tire pressure warning valve and transmitters for two sets
of wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels of both normal tires and snow tires
are registered beforehand.
For information about changing ID codes, ask any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.

WARNING

■

When inspecting or replacing tires

Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drivetrain as well as dan-
gerous 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.

●

Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.

■

When initializing the tire pressure warning system

Do not initialize the tire pressure warning system without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps

●

When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as the tire pressure warning
valves and transmitters may be damaged if not handled correctly.

●

Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.

●

When replacing tire valve caps, do not use tire valve caps other than those
specified.
The cap may become stuck.

■

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.

■

To avoid damage to the tire pressure warning valves and transmitters

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
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer or other qualified service shop as soon as possible. After use of liq-
uid sealant, make sure to replace the tire pressure warning valve and trans-
mitter when repairing or replacing the tire. (

Tire inflation pressure

■

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 drivetrain

If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

■

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 1.5 km or 1 mile, 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.

●

Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. (

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.

632

6-3. Do-it-yourself maintenance

Wheels

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 any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.

: 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 1600 km (1000 miles).

●

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.

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 (except for compact spare tire) that allow the tire pressure
warning system to provide advance warning in the event of a loss in tire infla-
tion pressure. Whenever wheels are replaced, tire pressure warning valves
and transmitters must be installed. (



P. 616)

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 tube-
less tire. Doing so may result in an accident, causing death or serious
injury.

■

When installing the wheel nuts

●

Be sure to install the wheel nuts with the tapered ends facing inward.
(



P. 736) Installing the nuts with the tapered ends facing outward can

cause the wheel to break and eventually cause the wheel to come off
while driving, which could lead to an accident resulting in death or serious
injury.

●

Never use oil or grease on the wheel bolts or wheel nuts.
Oil  and  grease  may  cause  the  wheel  nuts  to  be  excessively  tightened,
leading  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 acci-
dent  and  resulting  in  death  or  serious  injury.  Remove  any  oil  or  grease
from the wheel bolts or wheel nuts.

■

Use of defective wheels prohibited

Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
