formed.
8 Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes. Initialization is comple te when the position
of each tire is determ ined and the inflation
pressure of each tire is displayed on the
multi-information display.
Initialization may take longer than normal
to complete if the vehicle speed cannot be
maintained at approx imately 25 mph (40
km/h) or more. If initialization cannot be
completed after driving for 1 hour or more,
park the vehicle in a safe place, turn the

Maintenance and care ■
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 the engine switch is turned off during
initialization, it is not necessary to restart
the initialization pr ocedure from the
beginning as it will begin automatically
when the engine switch is turned back to
IGNITION ON mode.●
If initialization has accidentally been
started when it is not necessary, adjust
the tire inflation pres sure to the specified
level when the tires are cold and then
perform the initia lization procedure
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 tran smitters of your
vehicle over those of other vehicles.
If initialization is no t 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.
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.
The ID codes can be registered on
of the multi-information display.
1 Park the vehicle in a safe place, turn
the engine switch off, wait 20 min-
utes or more, and then start the
engine. WARNING■
When initializing the tire pressure
warning system
Do not initialize the tire pressure warning
system 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 in flation pressure is
actually normal.
