switch off during initialization, it is not
necessary to manually restart the initial-
ization again, as initialization will restart
automatically the next time the engine
switch is turned to ON.
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)
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
6-3. Do-it-yourself maintenance
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
pressure is low, or it may come on when
the tire inflation pressure is actually nor-
mal.
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
