■ Warning performance of the tire pres-
sure warning system (Setting using the
current tire inflation pressure)
● When performing the tire pressure set-
ting using the current tire inflation pres-
sure, the warning timing of the tire
pressure warning system will vary
according to the conditions under which
tire pressure setting was performed.
Therefore, a warning may be output even
if the tire inflation pressure drops slightly
or if the tire inflation pressure increases
above that when the tire inflation pres-
sure was set.
● Make sure to perform the tire pressure
setting procedure after adjusting the tire
inflation pressure. Also, make sure the
tires are cold before performing the tire
pressure setting procedure or adjusting
the tire inflation pressure.
■ Tire inflation pressure setting proce-
dure (Setting using the current tire infla-
tion pressure)
● If the engine switch is turned off while set-
ting the tire inflation pressure, the next
time the engine switch is turned to IGNI-
TION ON mode, the setting procedure
will resume and it will not be necessary to
restart the procedure.
● If the tire inflation pressure setting proce-
dure is started unnecessarily, adjust the
tire inflation pressure to the specified
level with the tires cold and then perform
setting by selecting a specified tire infla-
tion pressure, or perform the tire inflation
pressure setting procedure with the cur-
rent tire inflation pressure.
■ If the tire inflation pressure cannot be
set easily
● Normally, it takes approximately 3 min-
utes to complete the setting procedure to
the current tire inflation pressure.
● If the tire pressure warning light does not
blink 3 times when starting the tire infla-
tion pressure setting procedure, the pro-
cedure may not have started. Perform the
procedure again from the beginning.
● If tire inflation pressure setting procedure
cannot be completed after performing
the above procedure, contact your Lexus
dealer.
■ When to register ID codes
The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When new tire pressure
warning valves and transmitters are
installed, new ID codes must be regis-
tered in the tire pressure warning com-
puter.
■ How to registration ID code
Before performing ID code registra-
tion, make sure that no wheels with tire
pressure warning valve and transmit-
ters installed are near the vehicle.
WARNING
■ When setting using the current tire
inflation pressure
Make sure to adjust the tire inflation
pressure of each tire to the appropriate
level before performing tire pressure set-
ting. Otherwise, the tire pressure warn-
ing light may not illuminate even if the tire
inflation pressure drops or may illuminate
even though the tire inflation pressure is
normal.
