3086-3. Do-it-yourself maintenance
■Replacing tires and wheels
If the ID code of the tire pressure warning
valve and transmitter is not registered, the
tire pressure warning system will not work
properly. After driving for about 20 min-
utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.
■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 or load weight.
 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, turn
the engine switch off and wait 20
minutes or more.
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 infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Start the engine. ( P.134)
4 Press and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks slowly
3 times.
Then a message will be displayed on the
NOTICE
■Repairing or replacing tires, wheels,
tire pressure warning valves, trans-
mitters and tire valve caps
●When removing or fitting the wheels,
tires or the tire pressure warning
valves and transmitters, contact your
Lexus dealer as the tire pressure warn-
ing valves and transmitters may be
damaged if not handled correctly.
●Make sure to install the tire valve caps.
If a tire valve cap is not installed, water
may enter the valve and cause it to
corrode, possibly leading to the valve
sticking or air to leak from the tire.
●When replacing tire valve caps, do not
use tire valve caps other than those
specified. The cap may become stuck.
■To avoid damage to the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressu re 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 re place the tire pres-
sure warning valve and transmitter when
repairing or replacing the tire.
Initializing the tire pressure

Maintenance and care
multi-information display.
5Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
Initialization is complete when the position
of each tire is determined and the inflation
pressure of each tire is displayed on the
multi-information display.
■Initialization procedure
●Make sure to perform the initialization
procedure after adjusting the tire inflation
pressure.
Also, make sure the tires are cold before
performing the initialization procedure or
adjusting the tire inflation pressure.
●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 pr ess the reset switch
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
pressure of a tire drops, the tire pressure
warning light will come on.
■If the tire pressure warning system is not
initialized properly
●In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. (Usually,
the vehicle will need to be driven for
approximately 10 to 30 minutes to com-
plete initialization.) If initialization is not
complete after drivin g approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved
road, it may take longer to complete ini-
tialization.
• If the vehicle is backed up while perform-
ing initialization, data collected during ini-
tialization will be cleared and it will take
longer than normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other vehicles
are driven close by, it may take time for
the system to recognize the tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles.
If initialization is not complete after driving
for approximately 1 hour, park the vehicle in
a safe place for approximately 20 minutes
and then drive the vehicle again.
●In the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization proce-
dure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes after performing ini-
tialization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
●If initialization canno t be completed after
performing the above procedure, con-
tact your Lexus dealer.

3106-3. Do-it-yourself maintenance
Every tire pressure warning valve and
transmitter has a unique ID code.
When replacing a tire pressure warn-
ing valve and transmitter, it is necessary
to register the ID codes.
1Park the vehicle in a safe place, turn
the engine switch off, wait 20 min-
utes or more, and then start the
engine.
Registering cannot be performed while the
vehicle is moving.
2Start the engine. ( P.134)
3 Press the tire pressure warning
reset switch 3 times quickly.
The tire pressure wa rning light will blink
slowly 3 times.
Sensor registration mode will be entered
and ID codes registration will begin.
A message will be displayed on the
multi-information display and “- -” will be
displayed for the tire inflation pressure of
each tire.
After this, the tire pressure warning light will blink for 1 minute
and then illuminate.
4Wait approximately 2 minutes.
If the ID codes are already registered, the
tire pressure warning light will turn off.
If the tire pressure warning light
turns off
5 Initialize the tire pressure warning
system. ( P.308)
If the tire pressure warning light
does not turn off
5 Drive at approximately 25 mph
(40 km/h) or more until the tire
pressure warning light turns off.
6 Initialize the tire pressure warning
system. ( P.308)
■When registering ID codes
●Before performing ID code registration,
make sure that no wheels with tire pres-
sure warning valve and transmitters
installed are near the vehicle.
●Make sure to initializ e the tire pressure
warning system after registering the ID
codes. If the system is initialized before
registering the ID codes, the initialized
values will be invalid.
●As the tires will be warm when registra-
tion is completed, ma ke sure to allow the
tires to cool before performing initializa-
tion.
■Canceling ID code registration
●To cancel ID code regi stration after it has
been started, turn the engine switch off
WARNING
■When initializing the tire pressure
warning system
Do not operate the ti re 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.
