7664-3. Do-it-yourself maintenance
LX570_OM_OM60L96U_(U) Tires Replace or rotate tires in accordan ce with maintenance schedules and
treadwear.
■ Checking tires
New tread
Treadwear indicator
Worn tread The location of treadwear indi-
cators is shown by the “TWI” or
“ ” marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
pressure if not rotated.
■ Tire rotation
Rotate the tires in the order
shown. To equalize tire wear and
extend tire life, Lexus recom-
mends that tire rotation is car-
ried out at the same interval as
tire inspection.
Do not fail to initialize the tire
pressure warning system after
rotating the tires that the tire
pressure has been changed for
towing. (  P. 767)
■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low tire

Maintenance and care
LX570_OM_OM60L96U_(U) Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lves 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 pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. (  P. 768)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
● When rotating the tires in above situation.
● When the set tire pressure has been changed before towing.
(  P. 895)
When the tire pressure warning sy stem is initialized, the current tire
