2021 Lexus LC500C initializing

2866-3. Do-it-yourself maintenance
■The tire pressure warning system
must be initialized in the following
circumstances:
 When rotating the tires.
 When the tire inflation pressure is
changed when changing traveling
speed.
 When the tire inflation pressure is
changed such as when changing tire
size. (When there are multiple spec-
ified pressures)
 After registering the ID codes.
( P.287)
When the tire pressure warning sys-
tem is initialized, the current tire infla-
tion pressure is set as the benchmark
pressure.
■How to initialize the tire pressure
warning system
1 Park the vehicle in a safe place and
turn the engine switch off.
Initialization cannot be performed while
the vehicle is moving.
2 Adjust the tire inflation pressure to
the specified cold tire inflation
pressure level.
Make sure to adjust th e tire pressure to the
specified cold tire infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Turn the engine switch to ON.
4 Press or of the meter con-
trol switches and select . 5
Press or of the meter con-
trol switches and select “Vehicle
Settings”, then press “OK”.
6 Press or of the meter con-
trol switches and select “TPWS
SET”, then press “OK”.
7 Press or of the meter con-
trol switches and select “Set tire
pressure”. Then press and hold
“OK” until the tire pressure warn-
ing light starts blinking.
A message is displayed on the multi-infor-
mation display. Also, “--” is displayed for
inflation pressure of each tire on the multi-
information display while the tire pressure
warning system determines the position.
8Drive the vehicle at approximately
25mph (40 km/h) or more for
approximately 10 to 30 minutes.
When initialization is complete, the infla-
tion pressure of each tire will be displayed
on the multi-information display.
Depending on the vehicle and driving con-
ditions, initialization may take up to
approximately 1 hour to complete.
■The initialization operation
●Make sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initialization or tire inflation
pressure adjustment.
●If you have accidentally turned the engine

Maintenance and care
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 pres sure 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 lo nger 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 occasi onal 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 init ialization, 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 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. Initia
lize the tire pressure
warning system after the tires become
cold.
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 to ON.
2
Press or of the meter con-
trol switches and select .
3
Press or of the meter con-
trol switches and select “Vehicle
Settings”, then press “OK”.
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the spec ified 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.
