Vehicles with front and rear tires of
the same size
Rotate the tires in the order shown. To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same in terval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation. 
Vehicles with front and rear tires of
differing sizes
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 side wall. 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 ti re inflation pressure 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.

Maintenance and care ■
Initialization procedure●
Make sure to perform the initialization
procedure after adjusting the tire inflation
pressure.
Also, make sure the tires are cold before
performing the initialization procedure or
adjusting the tire inflation pressure.●
If the engine switch is turned off during
initialization, it is not necessary to restart
the initialization pr ocedure from the
beginning as it will begin automatically
when the engine switch is turned back to
IGNITION ON mode.●
If initialization has accidentally been
started when it is not necessary, adjust
the tire inflation pres sure to the specified
level when the tires are cold and then
perform the initia lization procedure
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
pressure of a tire drops, the tire pressure
warning light will come on.■
If the tire pressure warning system is not
initialized properly●
In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. (Usually,
the vehicle will need to be driven for
approximately 10 to 30 minutes to com-
plete initialization.) If initialization is not
complete after drivin g approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved
road, it may take longer to complete ini-
tialization.
• If the vehicle is backed up while perform-
ing initialization, data collected during ini-
tialization will be cleared and it will take
longer than normal to complete.
• If the vehicle is driven in heavy traffic or
another situation where other vehicles
are driven close by, it may take time for
the system to recognize the tire pressure
warning valve and tran smitters of your
vehicle over those of other vehicles.
If initialization is no t complete after driving
for approximately 1 hour, park the vehicle in a safe place for approximately 20 minutes
and then drive the vehicle again. ●
In the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization proce-
dure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes after performing ini-
tialization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates. ●
If initialization canno t be completed after
performing the above procedure, con-
tact your Lexus dealer.
Every tire pressure warning valve and
transmitter has a unique ID code.
When replacing a tire pressure warn-
ing valve and transmitter, it is necessary
to register the ID codes.
The ID codes can be registered on
of the multi-information display.
1 Park the vehicle in a safe place, turn
the engine switch off, wait 20 min-
utes or more, and then start the
engine. WARNING■
When initializing the tire pressure
warning system
Do not initialize the tire pressure warning
system without first adjusting the tire
inflation pressure to the specified level.
Otherwise, the tire pressure warning
light may not come on even if the tire
inflation pressure is low, or it may come
on when the tire in flation pressure is
actually normal.
