Maintenance and care
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 Toy-
ota dealer. (P.420)
■ Replacing tires and wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.
■ The tire pressure warning
system must be initialized
in the following circum-
stances:
When the tire inflation pres-
sure is changed such as
when changing traveling
speed.
When the tire inflation pres-
sure is changed such as
when the tire size is changed.
When rotating the tires.
After registering the ID codes.
(P.420)
When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.
NOTICE
■ Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
● When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
● Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
● When replacing tire valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■ To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repaired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant 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.416)
