Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
Fitting tire chains (vehicles without 19 inch tires)
The tire pressure warning valves and transmitters may not function cor-
rectly when tire chains are fitted.
When standing the windshield wipers up
Raise the wipers in line with the windshield. (P. 362)
Failure to do so may result in damage to the wipers and/or the hood.

Maintenance and care
GS350/250_EE (OM30C36E)Rotate the tires in the order shown.
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. (vehicle with the tire pressure warning system)

6746-3. Do-it-yourself maintenance
GS350/250_EE (OM30C36E)Your vehicle is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low tire
inflation pressure before serious problems arise.
Vehicles without the tire inflation pressure display function
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 753)
Vehicles with the tire inflation pressure display function
If the tire pressure drops below a predetermined level, the driver
is warned by a screen display and a warning light. (P. 772)
The tire pressure detected by the tire pressure warning system
can be displayed on the multi-information display. (P. 106)
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional. (P. 676)

Initializing the tire pressure warning system
The tire pressure warning system must be initialized in the fol-
lowing circumstances:
When rotating the tires.
When the tire inflation pressure is changed such as when
changing traveling speed.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the benchmark pressure.
How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (P. 850)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the engine switch to IGNITION ON mode.
