carrying out initialization or tire inflation
pressure adjustment.
● If you have accidentally turned the engine
switch <power switch> off during initial-
ization, it is not necessary to manually
restart the initialization again, as initializa-
tion will restart automatically the next
time the engine switch <power switch> is
turned to IGNITION ON mode <ON
mode>.
● If you accidentally perform initialization
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
While the position of each tire is being
●
determined and the inflation pressures
are not being displayed on the multi-
information display, if the inflation pres-
sure of a tire drops, the tire pressure
warning light will come on.
When initialization of the tire pressure
■
warning system has failed
Initialization may take longer to complete if
the vehicle is driven on an unpaved road.
When performing initialization, drive on a
paved road if possible. Depending on the
driving environment and condition of the
tires, initialization will be completed in
approximately 10 to 30 minutes. If initializa-
tion is not complete after driving approxi-
mately 10 to 30 minutes, continue driving
for a while. If the inflation of each tire is not
displayed after driving for approximately 1
hour, perform the following procedure.
● Park the vehicle in a safe place for
approximately 20 minutes. Then drive
straight (with occasional left and right
turns) at approximately 25 mph (40
km/h) or more for approximately 10 to
30 minutes.
However, in the following situations, the tire
inflation pressure will not be recorded and
the system will not operate properly. Per-
form initialization again.
When performing initialization, the tire
●
pressure warning light does not blink 3
times. (initialization will not occur while
driving)

6-3. Do-it-yourself maintenance
After performing initialization, the tire
●
pressure warning light blinks for 1 minute
then stays on after driving for about 20
minutes.
If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
your Lexus dealer.
■ When registering ID codes
Initialize the tire pressure warning system
●
after ID code registration. Initialization is
disabled if the system was initialized
before registration.
● After ID code registration, the tires are
hot by driving. Initialize the tire pressure
warning system after the tires become
cold.
WARNING
When initializing the tire pressure
■
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the specified level. Other-
wise, the tire pressure warning light may
not come on even if the tire inflation pres-
sure is low, or it may come on when the
tire inflation pressure is actually normal.
Registering ID codes
The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When replacing a tire pres-
sure warning valve and transmitter, it is
necessary to register the ID code.
When registering the ID codes, per-
form the following procedure.
1
Turn the engine switch <power
switch> to IGNITION ON mode
<ON mode>.
2
Press or of the meter con-
trol switches and select
