Maintenance and care
Vehicles with front and rear tires of
the same size
Vehicles with front and rear tires of
differing sizes
To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
■When rotating the tires
Make sure that the engine switch <power switch> is off. If the tires are rotated while
the engine switch <power switch> is in IGNITION ON mode <ON mode>, the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch <power switch> to off and then to IGNITION ON mode <ON mode>,
or initialize the tire pr essure warning system after checking that the tire pressure is prop-erly adjusted.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
conditions.)
A run-flat tire has a mark on
the side wall.
Make sure to replace the flat tire before the
vehicle has been driven for near 160 km
(100 miles). Also, do not use a repaired
tire.
■Run-flat tires
●The run-flat tires are for only this vehicle. Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon- strate the performanc e of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.374)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information

display. (P.92)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop- erly.• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.• A tire has been replaced with a tire that is
not of the specified size. • Tire chains etc. are equipped.• An auxiliary-supported run-flat tire is
equipped. • If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.• If wheels without tire pressure warning
valves and transmitters are used. • If the ID code on the tire pressure warn-ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing situations. • Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise• When carrying a portable radio, cellular
phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rap-
idly for example when a tire has burst, the warning may not function.
■Warning performance of the tire pres-sure warning system
The warning of the tire pressure warning system will change in accordance with the
conditions under which it was initialized. For this reason, the system may give a warning
even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.

light starts blinking.
A message is displayed on the multi-infor- mation display. Also, “--” is displayed for inflation pressure of each tire on the multi-
information display while the tire pressure warning system determines the position.
8 Drive the vehicle at approximately
40 km/h (25mph) or more for
approximately 10 to 30 minutes.
When initialization is complete, the infla- tion pressure of each tire will be displayed on the multi-information display.
Depending on the vehicle and driving con- ditions, initialization may take up to
approximately 1 hour to complete.
■The initialization operation
●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 <power switch> off during initial- ization, it is not ne cessary to manually restart the initializatio n again, as initializa-
tion will restart automatically the next time the engine switch <power switch> is turned to IGNITION ON mode <ON
mode>.
●If you accidentally perform initialization
when initialization is not necessary, adjust the tire inflation pressure 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 pres-
sure of a tire drops, the tire pressure warning light will come on.
■When initialization of the tire pressure warning system has failed
Initialization may take longer to complete if
the vehicle is driven on an unpaved road. When performing initialization, drive on a paved road if possible. Depending on the
driving environment an d condition of the tires, initialization will be completed in approximately 10 to 30 minutes. If initializa-
tion is not complete after driving approxi- mately 10 to 30 minutes, continue driving for a while. If the inflation of each tire is not
displayed after driving for approximately 1 hour, perform the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then drive straight (with occasional left and right
turns) at approximately 40 km/h (25 mph) or more for approximately 10 to 30 minutes.
However, in the following situations, the tire
inflation pressure will not be recorded and
the system will not operate properly. Per-
form initialization again.
●When performing init ialization, the tire

pressure warning light does not blink 3 times. (Initialization will not occur while driving)
●After performing init ialization, the tire pressure warning light blinks for 1 minute
then stays on after driving for about 20 minutes.
If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
■When registering ID codes
●Initialize the tire pressure warning system after ID code registra tion. Initialization is
disabled if the system was initialized before registration.
●After ID code registration, the tires are hot by driving. Initia lize the tire pressure warning system after the tires become
cold.
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.
When registering the ID codes, per-
form the following procedure.
1 Turn the engine switch <power
switch> to IGNITION ON mode
<ON mode>.
2 Press or of the meter con-
trol switches and select .
3 Press or of the meter con-
trol switches and select “Vehicle

4 Press or of the meter con-
trol switches and select “TPWS
SET”, and then press “OK”.
5 Press or of the meter con-
trol switches and select “Change
wheel set”, and then press and hold
“OK” until the tire pressure warning
light starts blinking.
The change wheel set mode is activated and registration is started.
A message is displayed on the multi-infor- mation display, and “--” is displayed for inflation pressure of e ach tire. Then, the tire
pressure warning light blinks rapidly for approximately 1 minute and stays on.
6 Drive the vehicle at 40 km/h
(25mph) or more for approxi-
mately 10 to 30 minutes.
When registration is completed, the tire pressure warning light will go off and the inflation pressure of each tire will be dis-
played on the multi-information display.
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation pressure to the specified level. Other-wise, the tire pressure warning light may
not come on even if the tire inflation pres- sure is low, or it may come on when the tire inflation pressure is actually normal.
