utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.
■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 spec-
ified pressures)
 After registering the ID codes.
( P.312)
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 the tire pressure to the

■Repairing or replacing 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.

warning system determines the position.
8Drive the vehicle at approximately
25mph (40 km/h) 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 ou t initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
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 longer to complete if
the vehicle is driven on an unpaved road.
When performing initia lization, 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 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 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.

Maintenance and care
●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 warning 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.
 Stop the vehicle in a safe place on a
hard, flat surface.
 Set the parking brake.
 Shift the shift position to P.
 Stop the engine .

WARNING
■When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, resulting 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.
■After using the tools
Before driving, make sure all the tools are
stored securely in place. Failure to do so
may cause injury in case of a collision or
sudden braking.

Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pressure
gauge onto the tire valve.
3 Read the pressure using the gauge
gradations.
4 If the tire inflation pressure is not at
the recommended level, adjust the
pressure.
If you add too much air, press the
center of the valve to deflate.
5 After completing the tire inflation
pressure measurem ent and adjust-
ment, apply soapy water to the
valve and check for leakage.
6 Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure
every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pres-
sure
Driving with incorrect ti re inflation pressure
may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor han-
dling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it
checked by your Lexus dealer.
■Instructions for checking tire inflation
pressure
When checking tire inflation pressure,
observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven for more than 1 mile or 1.5 km, you will get an
accurate cold tire inflation pressure read-
ing.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the ti
re inflation pressure
to be higher after driving as heat is gen-
erated in the tire. Do not reduce tire infla-
tion pressure after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight should
be placed so that the vehicle is balanced.

WARNING
■Proper inflation is critical to save tire
performance
Keep your tires properly inflated.
If the tires are not properly inflated, the
following conditions may occur which
could lead to an accident resulting in
death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from
overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards,
expansion joints, sharp edges in the
road, etc.)

WARNING
●Never use an inner tube in a leaking
wheel which is designed for a tubeless
tire. Doing so may result in an acci-
dent, causing death or serious injury.
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air
during driving, possibly causing an acci-
dent.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning
valves and transmitters, make sure to
have tires serviced by your Lexus
dealer or other qualified service shop.
In addition, make sure to purchase
your tire pressure warning valves and
transmitters at your Lexus dealer.
●Ensure that only ge nuine Lexus wheels
are used on your vehicle.
Tire pressure warning valves and trans-
mitters may not work properly with
non-genuine wheels.
