COROLLA_TMMMS_TMMC_U
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. ( P. 480)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
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 your Toyota dealer. ( P. 443)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When changing the tire size.
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
When the tire pressure warning sy stem 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 off .
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 546)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure 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).
Open the glove box. Press
and hold the tire pressure
warning reset switch until the
tire pressure warning 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.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve an d
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:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot 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 a tire pressure warning
system)
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for 1
minute and stays on to indi cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks (vehicles with a tire pr essure
warning system)
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (17-inch tires)
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on sno wy and/or
icy roads and drive carefully at a speed appropriate for road a nd weather
conditions.

COROLLA_TMMMS_TMMC_U■
Maximum load of tire
Check that the maximum load of t
he replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axl e or the
rear axle, whichever is greater.
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to hi ghway
driving under dry conditions. Si nce summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. 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 sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 263)
■Initializing the tire pressure warning system (vehicles with a tire
pressure warning system)
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost. 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. ( P. 5 5 1 )

If initialization is performed, adjust the tire inflation press ure to the speci-
fied level and initialize the tire pressure warning system again.
■When initialization of the tire pressure warning system has fai led
(vehicles with a tire pressure warning system)
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●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 initializa tion has been
completed, the warning light comes on after blinking for 1 minute.

WARNING
■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 accide nt
resulting in death o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of re markably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have b een used on another vehicle.
Do not use tires if you do not kn ow how they were used previous ly.
■When initializing the tire pressure warning system (vehicles wi th a
tire pressure warning system)
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. O therwise, the
tire pressure warning light may not come on even if the tire in flation
pressure is low, or it may come on when the tire inflation pres sure is
actually normal.

NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warn-
ing system)
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not hand led
correctly.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmi t-
ters (vehicles with a tire pressure warning system)
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replac e the tire pressure warning valve and
transmitter when replacing the tire. ( P. 4 4 1 )
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■Low profile tires (17-inch tires)
Low profile tires may cause gre ater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay at tention
to the following:
●Be sure to use proper tire inflation pressure. If tires are und er-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may l ead to severe tire and wheel damage.
■If tire inflation pressure of e ach tire becomes low while drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.
