pressing the newly programmed 
button and observing the indicator 
light:
 Indicator light illuminates: Program-
ming of a fixed code device has 
completed. The garage door or 
other device should operate when a

 button is pressed and 
released.
 Indicator light flashes rapidly: The 
garage door opener motor or other 
device is equipped with a rolling 
code. To complete programming, 
firmly press and hold the Home-
Link ®
 button for 2 seconds then 
release it.
 If the garage door or other device 
does not operate,  proceed to “Pro-
gramming a rolling code system”.
5 Repeat the steps above to program 
another device for any of the

2 or more people may be necessary to 
complete rolling code programming.
1 Locate the “Learn” or “Smart” but-
ton on the garage door opener 
motor in the garage.
This button can usuall y be found where the  hanging antenna wire is attached to the 
unit. The name and color of the button may 
vary by manufacturer.  Refer to the owner’s 
manual supplied with the garage door 
opener motor for details.
2 Press and release the “Learn” or 
“Smart” button. Perform  3  within 30 seconds after per-
forming  2 .
3 Press and hold the desired Home-

 The tire pressure detected by the 
tire pressure warning system can be 
displayed on the multi-information 
display. (  P.80)
 If the tire pressure drops below a 
predetermined level, the driver is 
warned by a screen display and a 
warning light. (  P.419)
■
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.
■
Tire inflation pressure
●
It may take a few minutes to display the 
tire inflation pressure after the engine 
switch is turned to IGNITION ON mode. 
It may also take a few minutes to display 
the tire inflation pres sure after inflation 
pressure has been adjusted.
●
Tire inflation pressu re changes with tem-
perature. The displayed values may also  be different from the values measured 
using a tire pressure gauge. ■
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.
• If a tire has been replaced with a tire that 
is not an OE (Original Equipment) tire.
• If a tire has been replaced with a tire that 
is not of the specified size.
• If tire chains, etc. are installed.
• 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 much higher 
than the specified level.
• If wheels not equipped with tire pressure 
warning valves and transmitter 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 af fected in the fol-
lowing situations.
• When driving near a  TV tower, electric 
power plant, gas stat ion, radio station, 
large display, airport or  other facility that 
generates strong radi o waves or electri-
cal 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 changing 
the location of the vehicle as the radio wave 
conditions may change.
●
When the vehicle is stopped, the time 
taken for the warning to start or turn off 
may be longer.
●
When the inflation pressure of a tire 
drops rapidly, for example when a tire has 
burst, the warning may not operate.

LS500_OM_(U)_1810 ■
The tire pressure warning system 
must be initialized in the following 
circumstances:
 When the tire inflation pressure is 
changed such as when changing 
traveling speed or load weight.
 When the tire inflation pressure is 
changed such as when the tire size 
is changed.
 When rotating the tires.
 After performing the transmitter ID 
code registration procedure. 
(  P.389)
When the tire pressure warning system 
is initialized, the cu rrent 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.The initialization procedure cannot be 
started while the vehicle is moving.
2 Adjust the tire inflation pressure to 
the specified cold tire inflation pres-
sure level.Make sure to adjust th e 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.
4 Press   or   of the meter con-
trol switch to select  . 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 multi-informa-
tion display for the inflation pressure of 
each tire while initialization 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 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 
engine switch off and wait 20 minutes or 
more before performing the driving proce-
dure again. (  P.389)Initializing the tire pressure 
warning system

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.
6 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 each tire is displayed 
on the multi-information display.
Registration may take longer than normal 
to complete if the vehicle speed cannot be 
maintained at approximately 25 mph (40 
km/h) or more. If registration cannot be 
completed after driving for 1 hour or more,  perform the registrati on procedure again 
from the beginning.  (  P.390)
After registering the ID  codes, make sure 
to initialize the tire pressure warning sys-
tem. (  P.388)■
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 
before driving the vehicle.
If the vehicle is driven after ID code regis-
tration is started, to cancel registration, 
perform the ID code registration start 
procedure again and turn the engine 
switch off before driving. ●
If ID code registration has been canceled, 
the tire pressure warning light will blink 
for approximately 1 minute when the 
engine switch is tu rned to IGNITION 
ON mode and then  illuminate. The tire 
pressure warning system will be opera-
tional when the tire pressure warning 
light turns off.
●
If the warning light does not turn off even 
after several minutes  have elapsed, ID 
code registration may not have been can-
celled correctly. To cancel registration, 
perform the ID code registration start 
procedure again and then turn the engine 
switch off before driving.
■
If ID codes are not registered properly
●
In the following situations, ID code regis-
tration may take longer than usual to be 
completed or may not be possible. (Usu-
ally, the vehicle will need to be driven for
