●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with th e conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.
■Certification
 P. 6 1 8
When replacing tires or wheels,
tire pressure warning valves and
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. ( P.472)
■When replacing the 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 rotating the tires.
 When changing the tires.
 After registering the ID codes.
( P.472)
 When changing between two
registered wheel sets.

■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, corrode the 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.

approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When registration is completed, the
tire pressure warni ng light will go off
and the inflation pressure of each
tire will be displaye d on the multi-
information display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, registration can be com-
pleted by driving for a long time.

■When registering ID codes
●ID code registrati on is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performing ID code regis-
tration, make sure that no wheels
with tire pressure warning valve
and transmitters installed are near
the vehicle.
●Make sure to initi alize the tire
pressure warning system after
registering the ID codes. If the
system is initialized before regis-
tering the ID codes , the initialized
values will be invalid.
●ID codes can be registered by

garage, exhaust gases including
harmful carbon monoxide (CO)
may collect and enter the vehicle.
This may lead to death or a seri-
ous health hazard.
