Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters 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. 616)
◆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 your Toyota dealer. ( P. 555)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized 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 systemPark the vehicle in a safe place and turn the engine switch to the
“LOCK” position (vehicles without a smart key system) or off
(vehicles with a smart key system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 669)
Make sure to adjust the tire pressu re 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).
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
Vehicles without a smart key syst em: 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.

Maintenance and care
◆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:
●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 the 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 the 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.

■The initialization operation (vehicles with the tire pressure warning
system)
●Make sure to carry out in itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart key system) or off (vehicles with a smart key
system) during initialization, it is no t necessary to press the reset switch
again as initialization will restart aut omatically when the engine switch
has been turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehic les with a smart key system) for the
next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
■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 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 wa rning 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.

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 ti res (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
compact spare tire installed.
■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.
