2015 LEXUS LX570 warning light

8345-2. Steps to take in an emergency
LX570_OM_OM60L96U_(U) ■
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).

When trouble arises
8375-2. Steps to take in an emergency
LX570_OM_OM60L96U_(U) CAUTIONYour vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indi cate when the system is not operating properly. The
TPMS (tire pressure warning system) malf unction indicator is combined with the
low tire pressure telltale (tire pressure warning light). When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists . When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malf unctions may occur for a variety of rea-
sons, including the installation of replaceme nt or alternate tires or wheels on the
vehicle that prevent the TPMS (tire pre ssure warning system) from functioning
properly. Always check the TPMS (tire pressure warning system) malfunction tell-
tale after replacing one or more tires or wh eels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS (tire pressure warning
system) to continue to function properly.
NOTICE■
To ensure the tire pressure warning system operates properly
Do not install tires with different specificat ions or marks, as the tire pressure warn-
ing system may not operate properly.
