◆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
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.
■Proper storage of the spare tire
As an improperly stored spare tire may cause damage to the wire cable
that holds it, check that the s pare tire is stored properly on a daily basis.
• If the spare tire is slanted, the hoist assembly may be stuck in the
wheel opening. If the spare tire rattles while driving, it may not be fully
raised. Lower the spare tire to the ground and make sure that t he
hoist assembly is perpendicular to the wheel opening.
• Raise the tire slowly and steadily until a click is heard and the jack
handle skips.
• If the spare tire cannot be lowered, the wire cable may be sev ered.
Have the vehicle inspected at your Toyota dealer.
●If the stored spare tire is slanted or
causes a rattle while driving, properly
store the spare tire by following the tire
change procedure correctly ( P. 6 1 0 ) .

• If a window tint that affects the radio wave signals is instal led.
• 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 sp ecified
level.
• If the spare tire is in a location subject to poor radio wave signal
reception.
*
• If a large metallic object whic h can interfere with signal reception is
put in the luggage compartment.

NOTICE
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standard tires. Be careful when d riving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect dr iving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire p ressure
warning valve and transmitter may be damaged if not handled cor rectly.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
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. 5 3 5 )
■When stowing the flat tire
●Ensure that there is no object caught between the tire and the vehicle
underbody.
●Securely tighten the spare tire clamp bolt to hold the spare wh eel car-
rier by the hook.
●Stow the flat tire in the spare tire location. Failure to do so may cause
damage to the spare tire carrier. Proper storage reduces the po ssibility
of injury in a collision or during sudden braking.
●Have the flat tire repaired and the spare tire replaced with it as soon as
possible.
