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. 698)
◆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 any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. ( P. 635)
◆Initializing the tire pressure warning system
When the tire size is changed, the tire pressure warning system
must be initialized.
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 to the
“LOCK” position (vehicles without a smart entry & start system)
or off (vehicles with a smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 772)
Make sure to adjust the tire pressure to the specified cold tire inflation
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 entry & start system) or IGNITION ON mode (vehicles with
a smart entry & start system).

■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 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 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 t hat 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 engine switch to the “LOCK” position
(vehicles without a smart entry & start system) or off (vehicles with a smart
entry & start system) 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 IGNITION ON mode (vehicles with a smart entry
& start system) or engine switch to the “ON” position (vehicles without a
smart entry & start system) 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 blink 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 as soon as possible.

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 wa rning 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. ( P. 633)
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
