NOTICE■
To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels, etc.)●
Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the
paint surface
• If dead insects, in sect droppings or
bird droppings are present on the
paint surface
• After driving in an area contaminated
with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled
with dust or mud
• If liquids such as benzene and gasoline
are spilled on the paint surface ●
If the paint is chipped or scratched,
have it repaired immediately. ●
To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels. ■
Cleaning the exterior lights ●
Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights. ●
Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses. ■
When using an automatic car wash

If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged. ■
When using a high pressure car wash ●
When washing the vehicle, do not
spray the camera or its surrounding
area directly with a high pressure
washer. Shock applied from high pres-
sure water may cause the device to not
operate normally. ●
Do not bring the nozzle tip close to
boots (rubber or re sin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.

Maintenance and care 5 Press or to select “Vehicle
Settings” and then press .
6 Press or to select “TPWS”
and then press .
7 Press or to select “Set
Pressure”. Then press and hold
until the tire pressure warning light
blinks 3 times.Then a message will be displayed on the
multi-information display.
“--” will be displayed on the multiinforma-
tion display for the inflation pressure of
each tire while initia lization is being per-
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 complete when the position
of each tire is determined and the inflation
pressure of each tire is displayed on the
multi-information display.
Initialization may take longer than approxi-
mately 1 hour in certain situations, such as
when the vehicle is stopped for a long time
at traffic lights, etc. ( → P.393)
■
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 initia lization procedure or
adjusting the tire inflation pressure. ●
If the engine switch is turned off during
initialization, it is no t necessary to restart
the initialization procedure 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 pressure to the specified
level when the tires are cold and then
perform the initiali zation 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 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-

394 6-3. Do-it-yourself maintenance
LS500_OM_OM50F54U_(U) 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 cannot 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 Press or of the meter con-
trol switch to select .
2 Press or to select “Vehicle
Settings” and then press .
3 Press or to select “TPWS”
and then press . 4 Press or to select “Change
Wheel Set”. Then press and hold
until the tire pressure warning
light blinks slowly 3 times. Then a message will be displayed on the
multi-information display.
When registration is being performed, the
tire pressure warning light will blink for
approximately 1 minute then illuminate and
“--” will be displayed for the inflation pres-
sure of each tire on the multi-information
display.
5 Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes. Registration is complete when the tire
pressure warning light turns off and the
inflation pressure of ea ch tire is displayed
on the multiinformation display.
Registration may take longer than approxi-
mately 1 hour in certain situations, such as
when the vehicle is stopped for a long time
at traffic lights, etc. ( → P.395)
After registering the ID codes, make sure
to initialize the tire pressure warning sys-
tem. ( → P.392)
■
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 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 inflation pressure is
actually normal.
