uRegistering 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.
nWhen to replace your vehicle’s tires
Tires should be replaced if:
lThe treadwear indicators are showing on a tire.
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
lA 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.
nReplacing tires and wheels (vehicles with a 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.
nTire 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.
nRoutine tire inflation pressure checks (vehicles with a 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.
nLow profile tires (17-inch tires)
Generally, low profile tires will wear mo re rapidly and tire grip 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 snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.

NOTICE
nRepairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warn-
ing system)
lWhen 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 handled
correctly.
lWhen replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
nTo avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a 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 your Toyota dealer 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. 455)
nDriving 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.
nLow profile tires (17-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention
to the following:
lBe sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
lAvoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
nIf tire inflation pressure of e ach tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
lCheck 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 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
lAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
lIt 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.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
CAUTION
nProper 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:
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts result ing from overheated tires
lAir leaking from between tire and wheel
lWheel deformation and/or tire damage
lGreater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
nWhen 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.

COROLLA_TMMMS_TMMC_U (OM12J84U)n
When a tire is replaced with a spare tire (vehicles with a tire pressure
warning system)
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat,
the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
nConditions that the tire pressure warning system may not function
properly (vehicles with a tire pressure warning system)
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
lIf tires not equipped with tire pressure warning valves and transmitters
are used
lIf the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer
lIf the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
lIf electronic devices or facilities using similar radio wave frequencies are
nearby
lIf a radio set at similar frequency is in use in the vehicle
lIf a window tint that affects the radio wave signals is installed
lIf there is a lot of snow or ice on th e vehicle, in particular around the
wheels or wheel housings
lIf non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
lIf tire chains are used
nIf the tire pressure warning light frequently comes on after blinking
for 1 minute (vehicles with a tire pressure warning system)
