Maintenance and care
Tires cannot be rotated.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
A run-flat tire has a mark on
the sidewall.
Make sure to replace the flat tire before the
vehicle has been driven for near 100 miles
(160 km). 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 performance 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.344)

WARNING
●Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those
recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-b elted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
■Low profile tires (21-inch tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
●Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■If tire inflation pres sure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.

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.
■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
specified cold tire infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.

■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.

light comes on red, the assist to the power steering is lost and handling operations of the
steering wheel become extremely heavy. When steering wheel operations are heavier
than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.
●Decelerate to the lowest appr opriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
●Check and adjust the tire in flation pressure immediately.
●If the tire pressure warning lig ht comes on even after tire inflation pressure adjustment,
it is probable that you have a flat tire. Have the flat tire replaced by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
