Installing tire pressure warning valves and transmitters (if equipped)
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 warn-
ing computer and the tire pressure warning system must be initial-
ized. Have tire pressure warning valve and transmitter ID codes
registered by any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional. (P. 447)

Tire pressure warning system (if equipped)
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.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 517)

Maintenance and care
Initializing the tire pressure warning system (if equipped)
The tire pressure warning system must be initialized in the fol-
lowing circumstances:
When rotating front and rear tires which have different tire infla-
tion pressures
When the tire inflation pressure is changed such as when
changing traveling speed
When changing the tire size
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 (if
equipped)
Park the vehicle in a safe place and turn the engine switch to
the “LOCK” position (vehicles without smart entry & start sys-
tem) or the “ENGINE START STOP” switch off (vehicles with
smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (P. 621)
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
smart entry & start system) or the “ENGINE START STOP”
switch to IGNITION ON mode (vehicles with smart entry &
start system).

Maintenance and care
Registering ID codes (vehicles with the tire pressure warning system)
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 dealer or repairer, or another
duly qualified and equipped professional.
When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or 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 dealer or repairer, or
another duly qualified and equipped professional.
Replacing tire and wheels (vehicles with the tire pressure warning sys-
tem)
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 tires over 6 years old must be checked by a qualified technician even if
they have seldom or never been used or damage is not obvious.

Routine tire inflation pressure checks (vehicles with the tire pressure
warning system)
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 rou-
tine of daily vehicle checks.
Initializing the tire pressure warning system (if equipped)
Initialize the system with the tire inflation pressure adjusted to the specified
level.
If the tread depth wears down to 4 mm (0.16 in.) or more on snow tires
The effectiveness of snow tires is lost.
When initialization of the tire pressure warning system has failed (if
equipped)
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 dealer or
repairer, or another duly qualified and equipped professional.
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.

Maintenance and care
CAUTION
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 winter 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.
When initializing the tire pressure warning system (if equipped)
Do not operate the tire pressure warning reset switch 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 (vehicles with the tire pressure warn-
ing system)
When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional 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.
To avoid damage to the tire pressure warning valves and transmitters
(vehicles with the 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
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional 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. 444)
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.
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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 and 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.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced. Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 621)

CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury.
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps have been lost,
replace them as soon as possible.

460 4-3. Do-it-yourself maintenance
When removing the wheel ornament (vehicles with the wheel cap clip)
When replacing wheels (vehicles with the tire pressure warning sys-
tem)
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters (except for spare tire) 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
transmitters must be installed.
(P. 444)
CAUTION
When replacing wheels
Observe the following precautions to reduce the risk of death or serious
injury.
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a tube-
less tire.
When installing the wheel nuts
Remove the wheel ornament using the
wheel cap clip.
Be sure to install the wheel nuts with
the tapered ends facing inward. Install-
ing the nuts with the tapered ends fac-
ing 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.Tapered
