on the towing hook and rope.
The towing hook or rope may become damaged, broken debris may hit people
and cause serious damage.●
Do not turn the “POWER” switch off.
There is a possibility that the steering wheel is locked and can not be operated.■
Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing.
NOTICE■
To prevent damage to the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequa te ground clearance for towing at the
opposite end of the raised vehicle. Without adequate clearance, the vehicle could
be damaged while being towed.■
To prevent body damage when to wing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.■
Recreational towing (behind motor home, etc.)
Never dinghy tow your vehicle to prevent
causing serious damage to the AWD system
(AWD models) and transmission. (  P. 3 2 4 )

■
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure chan ges caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few min-
utes).■
When a tire is replaced with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with a tire pressure warning valve and trans-
mitter. If a tire goes flat, the tire pressure warning light will not turn off even though
the flat tire has been replaced with the spare tire. Replace the spare tire with the
repaired tire and adjust the tire inflatio n pressure. The tire pressure warning light
will go off after a few minutes.
Vehicles with a full-size 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 light does not turn off. Replace the spare tire with the
repaired tire and adjust to the proper tire inflation pressure. The tire pressure warn-
ing light will turn off after a few minutes.■
If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.) ●
If tires not equipped with tire pressure warning valves and transmitters are used●
If the ID code on the tire pressure warning 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 vehicle, in particular around the wheels or
wheel housings

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.

CAUTION■
Maintenance of the tires
Each tire, including the spare (if provided ), should be checked monthly when cold
and inflated to the inflation pressure re commended 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 size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicl e has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should 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).
Your vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indicate when th e 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) malfunctions may occur for a variety of rea-
sons, including the installation of replacem ent or alternate tires or wheels on the
vehicle that prevent the TPMS (tire pressure warning system) from functioning
properly. Always check the TPMS (tire pressure warning system) malfunction tell-
tale after replacing one or more tires or wheels 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.
