The tire pressure warning system
must be initialized in the following
circumstances:

When rotating the tires.

When the tire inflation pressure is
changed such as when changing
traveling speed.

When changing the tire size.
When the tire pressure warning system
is initialized, the current tire inflation
pressure is set as the benchmark pres-
sure.
■
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 pres-
sure level.
Make sure to adjust the tire pressure to the
specified cold tire inflation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Turn the engine switch to IGNI-
TION ON mode.
4 Press and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks slowly
3 times.
5
Wait for a few minutes with the
engine switch in IGNITION ON
mode and then turn the engine
switch off.

Initialization procedure
●
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
switch off during initialization, it is not
necessary to press the reset switch again
as initialization will restart automatically
when the engine switch has been turned
to IGNITION ON mode for the next
time.
●
If you accidentally press the reset switch
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
■
When initialization of the tire pressure
warning system has failed
Initialization can be completed in a few min-
NOTICE
■
To avoid damage to the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and
transmitter may not operate properly. If a
liquid sealant is used, contact your Lexus
dealer or other qualified service shop as
soon as possible. After use of liquid seal-
ant, make sure to replace the tire pres-
sure warning valve and transmitter when
repairing or replacing the tire. (
