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:
●
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 your Toyota dealer.
■
Replacing tires and wheels
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.
■
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 spare 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 the
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 severed.
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. 596).
