Driver's and front passengers seat belt reminders:


Driver's and front passengers seat belt reminders:

The drivers and front passengers seat belt reminder sounds to alert the driver and front passenger that his or her sear belt is not fastened. The buzzer sounds intermittently for 10 seconds after the vehicle has reached a speed of at least 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.

First check when the malfunction indicator lamp comes on while driving

Check the following:
- Is the fuel tank empty?

If it is, fill the fuel tank immediately.

- Is the fuel tank cap loose?

If it is, tighten it securely.

The lamp will go off after taking several driving trips.

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

If luggage or other load is placed on the front passenger seat, depending on its
weight, the reminder light may flash and buzzer may sound.

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 does not turn off the tire pressure warning light.

The tire pressure warning light may turn on due to natural causes

The tire pressure warning light may turn on due to natural causes such as natural air
leaks or 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 spare tire is also equipped with the tire pressure warning valve andFull-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 the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes.

The compact spare tire is not equipped with the tire pressure warning valve andCompact spare tire
The compact spare tire is not equipped with the 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 is replaced with the spare tire. Replace the spare tire with the
repaired tire and adjust the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes.

If the tire pressure warning system is inoperative

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 (vehicles with fullsize
spare tire).

- 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.

- If the full-size 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
trunk (vehicles with full-size spare tire).

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

If the tire pressure warning light comes on after blinking for 1 minute frequently
when the ENGINE START STOP switch is turned to IGNITION ON mode, have it checked by your Lexus dealer.

Customization that can be configured at Lexus dealer

The vehicle speed linked seat belt reminder buzzer can be disabled.

CAUTION:
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 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.

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.
