Maintenance and care
For vehicles sold in Canada
When replacing tires or wheels, tire
pressure warning valves and transmit-
ters must also be installed.
When new tire pressure warning
valves and transmitte rs are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. ( P.307)
■When replacing the 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.
Installing tire pressure warning
valves and transmittersNOTICE
■Repairing or replac ing 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 the tire valve caps are not installed,
water could enter the tire pressure
warning valves and the tire pressure
warning valves could be bound.
●When replacing tire valve caps, do not
use tire valve caps other than those
specified. The cap may become stuck.

■The tire pressure warning system
must be initialized in the following
circumstances:
When rotating the tires.
When the tire inflation pressure is
changed when changing traveling
speed.
When the tire inflation pressure is
changed such as when changing tire
size. (when there are multiple speci-
fied pressures)
After registering the ID codes.
( P.307)
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 and
turn the engine switch
switch> off.
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 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 Turn the engine switch

Maintenance and care
carrying out initializat ion or tire inflation
pressure adjustment.
●If you have accidentally turned the engine
switch off during initial-
ization, it is not necessary to manually
restart the initializatio n again, as initializa-
tion will restart automatically the next
time the engine switch is
turned to IGNITION ON mode
mode>.
●If you accidentally perform initialization
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 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 lo nger 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 and 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 inflatio n 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 occasi onal left and right
turns) at approximately 25 mph (40
km/h) 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
your Lexus dealer.
■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
switch> to IGNITION ON mode
.
2 Press or of the meter con-
trol switches and select .
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the spec ified level. Other-
wise, the tire pressu re 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.

A message is displaye d 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 25mph (40
km/h) or more for approximately
10 to 30 minutes.
When registration is completed, the tire
pressure warning light will go off and the
inflation pressure of e ach tire will be dis-
played on the multi-information display.
The time elapsed before registration is
completed differs according to the driving
condition and environment.
■Canceling the change wheel set mode
●If turning the engine switch
switch> off when in the change wheel set
mode before driving, the change wheel set mode is canceled.
●After driving when in the change wheel
set mode, the change
wheel set mode
cannot be canceled. To cancel the mode,
perform the procedure for ID code regis-
tration again and turn the engine switch
off before driving.
●If the change wheel set mode is canceled,
the ID codes that have already been reg-
istered are communicated. When com-
munication is finished, the tire pressure
warning light will turn off.
■When ID code registration may not
operate properly
●Do not move the vehicle backward
during registration. Re gistration is started
again from the beginning and it may take
longer than usual.
●When another vehicle is running the side
of the vehicle such as in heavy traffic, it
may take longer to detect the vehicle’s
tire pressure warnin g valves and trans-
mitters.
●If tire pressure warning valves and trans-
mitters are in the vehicle, the ID codes
may not be registered.
If registration takes long time, perform the
procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact your Lexus dealer.

WARNING
■When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, result ing in death or serious
injury.
●Never use oil or grease on the wheel
bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In
addition, the oil or grease can cause
the wheel nuts to loosen and the wheel
may fall off, causing a serious accident.
Remove any oil or grease from the
wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a
torque wrench to 103.3 ft•lbf (140
N•m, 14.3 kgf•m) soon as possible
after changing wheels.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel.
●If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.
