To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles) for 2WD models or
5000 km (3000 miles) for AWD models.
Do not fail to initialize the tire pressure
warning system after tire rotation.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
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 160 km
(100 miles). 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.

The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (

P.134)

If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. (

■
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 power
switch is turned to ON mode. It may also
take a few minutes to display the tire infla-
tion pressure after inflation pressure has
been adjusted.
●
Tire inflation pressure changes with tem-
perature. The displayed values may also
