Maintenance and care ■
The initialization operation ●
Make sure to carry out initialization af ter adjusting the tire inflation pressure. 
Also, make sure the tires are cold before carrying out initialization or tire infla-
tion pressure adjustment.●
If you have accidentally turned the “POWER ” switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart auto-
matically when the “POWER” switch has  been turned to ON mode for the next
time.●
If you accidentally press the reset switch  when initialization is not necessary,
adjust the tire inflation pressure to th e specified level when the tires are cold,
and conduct initialization again.■
When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few  minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer. ●
When operating the tire pressure warnin g reset switch, the tire pressure warn-
ing light does not blink 3 times. ●
After carrying out the initialization proc edure, the tire pressure warning light
blinks for 1 minute then stays on after driving for 20 minutes.

Maintenance and care CAUTION■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs.■
When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause
damage to parts of the drive train, as we ll as dangerous handling characteristics,
which may lead to an accident resu lting in death or serious injury.●
Do not mix tires of different makes, mode ls or tread patterns. Also, do not mix
tires of remarkably different treadwear.●
Do not use tire sizes other th an those recommended by Lexus.●

7405-2. Steps to take in an emergency
●
If non-genuine Lexus wheels are used  (Even if you use Lexus wheels, the tire
pressure warning system may not work properly with some types of tires.)●
If tire chains are used●
Vehicles with a full-size spare tire: If the spare tire is in a location subject to poor
radio wave signal reception●
Vehicles with a full-size spare tire: If a large metallic object which can interfere
with signal reception is pu t in the luggage compartment■
If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute
when the “POWER” switch is turned to ON mode, have it checked by your Lexus
dealer.■
Customization
The vehicle speed linked seat belt  reminder buzzer can be disabled. 
(Customizable features   P. 825)
CAUTION■
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy. 
If the steering wheel becomes heavier than  usual when operating, hold firmly and
operate 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 loss of
vehicle control and result in death or serious injury. ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.●
If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat  tire repaired by the nearest Lexus dealer.
●
Avoid abrupt maneuvering and braking. If the 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.
