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-
utes. However, in the following cases, the
settings have not been recorded and the
system will not operate properly. If repeated
attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle
inspected by your Lexus dealer.
●
When operating the tire pressure warn-
ing reset switch, the tire pressure warning
light does not blink 3 times.
●
After carrying out the initialization proce-
dure, the tire pressure warning light
blinks for 1 minute then stays on after
driving for 20 minutes.
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.
WARNING

When initializing the tire pressure
warning system
Do not operate the tire pressure warning
reset switch without first adjusting the tire
inflation pressure to the specified level.
Otherwise, 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 normal.
