Maintenance and care
● When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
● When tire inflation pressure declines rap-
idly for example when a tire has burst, the
warning may not function.
■ Warning performance of the tire pres-
sure warning system (vehicles with the
tire pressure warning system)
The warning of the tire pressure warning
system will change in accordance with the
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.
When replacing tires or wheels, tire
pressure warning valves and transmit-
ters 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. Have tire pressure warn-
ing valve and transmitter ID codes reg-
istered by your Lexus dealer. (P.331)
■ Replacing tires and wheels (vehicles
with the tire pressure warning system)
 Except for Chile
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 10 min-
utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.
 For Chile
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 min-
utes, the tire pressure warning light blinks
WARNING
■ Caution regarding interference with
electronic devices (vehicles with the
tire pressure warning system featur-
ing a tire inflation pressure display
function)
● People with implantable cardiac pace-
makers, cardiac resynchronization
therapy-pacemakers or implantable
cardioverter defibrillators should not
come within 450 mm (17.7 in.) of the
tire pressure warning system initiators.
The radio waves may affect the opera-
tion of such devices.
● Users of any electrical medical device
other than implantable cardiac pace-
makers, cardiac resynchronization
therapy-pacemakers or implantable
cardioverter defibrillators should con-
sult the manufacturer of the device for
information about its operation under
the influence of radio waves. Radio
waves could have unexpected effects
on the operation of such medical
devices.
