*1: Open door warning buzzer: The open door warning buzzer sounds to alert one or more of the doors is not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).

*2: Driver's and front passenger’s seat belt buzzer: The driver’s and front passenger’s seat belt buzzer sounds to alert the driver and
front passenger that his or her seat belt is not fastened. The buzzer sounds intermittently
for 10 seconds after the vehicle reaches a speed of 12 mph (20 km/h).

Then, if the seat belt is still unfastened, the buzzer will sound in a different tone
for 20 more seconds.

SRS warning light

This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensors, curtain shield airbag sensors, driver's seat
position sensor, driver's seat belt buckle switch, front passenger occupant classification
system, “AIR BAG ON” indicator light, “AIR BAG OFF” indicator light, front passenger's seat belt buckle switch, seat belt pretensioner assemblies, inflators,
interconnecting wiring and power sources.

Front passenger detection sensor, passenger seat belt reminder and warning buzzer

If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound even if a passenger is not sitting in the seat.

If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.

Electric power steering system warning light

When the voltage is low or drops, the electric power steering system warning light
may come on.

If the malfunction indicator lamp comes on while driving

Check that the fuel tank cap is not loose. If it is, tighten the cap securely.

The lamp will go off after several driving trips.

If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.

When the tire pressure warning light comes on

Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.

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 changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).

When a tire is replaced with a spare tire

The compact spare tire is not equipped with a tire pressure warning valve and transmitter.

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 inflation pressure. The tire pressure warning light
will go 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 registered
in the tire pressure warning computer.

If the tire pressure warning select switch is set to a different tire setting.

If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 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.

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 put in the luggage compartment.

If the tire pressure warning light comes on after flashing frequently for 1 minute

If the tire pressure warning light comes on after flashing frequently 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.

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 it 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 pressure
immediately.

If the tire pressure warning light comes on even after tire inflation pressure adjustment,
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 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 size than the size indicated on the vehicle
placard or tire inflation pressure label [tire and load information label], you should
determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS-tire pressure warning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire pressure telltale (tire pressure 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 underinflated
tire causes the tire to overheat and 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 the system is not operating properly. The TPMS (tire pressure warning system) malfunction 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 illuminated,
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 reasons,
including the installation of replacement 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 telltale
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.

NOTICE:
Precaution when installing a different tire When a tire of a different specification or maker is installed, the tire pressure warning
system may not operate properly.
