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) ■
Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once a month.
Do not forget to check the spare. ■
Effects of incorrect ti re inflation pressure
Driving with incorrect tire inflation pressure may result in the following:●
Reduced fuel efficiency ●
Reduced driving comfort and tire life ●
Reduced safety ●
Damage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer. ■
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following: ●
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading. ●
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure
that is even just a few pounds off can affect ride quality and handling.●
Do not reduce tire inflation pressure afte r driving. It is normal for tire inflation
pressure to be higher after driving. ●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

Tire pressure warning light
When the light comes on:
Low tire inflation pressure
such as
• Natural causes (  P. 832)
• Flat tire (  P. 854) Adjust the tire inflation pres-
sure (including the spare tire)
to the specified level.
The light will turn off after a
few minutes. In case the light
does not turn off even if the
tire inflation pressure is
adjusted, have the system
checked by your Lexus
dealer.
When the light comes on after
blinking for 1 minute:
Malfunction in the tire pres-
sure warning system.
(  P. 834) Have the system checked by
your Lexus dealer.Warning light Warning light/Details Correction procedure

When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare
tire is low. If a tire goes flat, even though the flat tire is replaced with the spare tire,
the tire pressure warning li ght does not turn off. Repl ace the spare tire with the
repaired tire and adjust the proper tire in flation pressure. The ti re pressure warning
light will turn off after a few minutes. ■
If the tire pressure warning system is inoperative
The tire pressure warning system will become inoperative in the following condi-
tions: (When the condition becomes norm al, the system will work properly.)●
If tires not equipped with ti re pressure warning valves and transmitters are used.●
If the ID code on the tire pressure warn ing valves and transmitters is not regis-
tered in the tire pressure warning computer. ●
If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm 2
or bar) or higher.
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.) ●
If electronic devices or facilities using similar radio wave frequencies are
nearby. ●
If a radio set at similar frequencies is in use in the vehicle. ●
If a window tint that affects the radio wave signals is installed. ●
If there is a lot of snow or ice on the ve hicle, in particular around the wheels or
wheel housings. ●
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. ●
If the spare tire is in a location subject to poor radio wave signal reception. ●
If a large metallic object which can interfere with signal reception is put 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 “ENGINE START STOP” switch is turned to IGNITION ON mode, have
it checked by Lexus dealer.
CAUTION■
If the tire pressure warning light comes on
Be sure to observe the following precauti ons. 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 come s on even after tire inflation pressure
adjustment, it is probab le that you have a flat tire. Chec k the tires. If the tire is flat,
change to 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.

LX570_OM_OM60L96U_(U) CAUTION■
Maintenance of the tires
Each tire, including the spare (if provided ), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label (tire and load information label).
(If your vehicle has tires of a different si ze than the size indi cated on the vehicle
placard or tire inflation pressure label [tire and load information label], you should
determine the proper tire inflati on pressure for those tires.)
As an added safety feature, your vehicl e has been equipped with a tire pressure
monitoring system (T PMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning ligh t) when one or more of your tires is sig-
nificantly under-inflated. Acco rdingly, when the low tire pr essure telltale (tire pres-
sure warning light) illuminates, you shou ld stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat an d can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).

LX570_OM_OM60L96U_(U) Installing the spare tire
Remove any dirt or foreign matter
from the wheel contact surface. If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, and the tire may come off
the vehicle.
Install the spare tire and loosely
tighten each nut by hand to
approximately the same amount. Turn the nut washers until they
come into contact with the disc
wheel.
Lower the vehicle.
Firmly tighten each nut two or
three times in the order shown in
the illustration. Tightening torque:
