5-2. Steps to take in an emergency
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 pressu re 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 vehicl e 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 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 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 driv er'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) 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 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 pres sure 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.

5-2. Steps to take in an emergency
■Sealant
●One tire can be repaired using the bottle of sealant stored in the emergency tire
puncture repair kit.
●The sealant can be used when the outside temperature is from -22°F (-30°C)
to 140°F (60°C).
●When the outside temperature is low, the viscosity of the sealant becomes high
and it will be more difficult to inject th e sealant. In this case, warm the sealant in
the vehicle before using it.
●The sealant has a limited lifespan. The expi ration date is marked on the bottle.
The sealant should be replaced before the expiration date. Contact your Lexus
dealer.
●If the sealant gets on your clothes, it may stain.
●After using the sealant, bring the empty bottle of sealant to your Lexus dealer
and purchase a new bottle. Keep the ne w bottle of sealant in your vehicle.
■Compressor
●The compressor is a pneumatic filling type for passenger vehicles.
●When the compressor is operating, a loud operating noise will be produced.
This does not indicate a malfunction.
■The wheel of a tire that has been repaired
If you remove the sealant adhering to the wheel with a rag, you can reuse the wheel.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the tire pres-
sure warning valve and transm itter should be replaced.
●After a tire is repaired with the emergency tire puncture repair kit, even if the
tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.

6-1. Specifications
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and
they represent the tire's ability to stop on wet pavement as measured
under controlled condit ions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turning) trac-
tion.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Mo tor Vehicle Safety Standard No. 139.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excess ive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

■Précautions avec les sacs de sécurité gonflables SRS
Respectez les précautions suivantes avec les sacs de sécurité gonflables.
À défaut, des blessures graves, voire mortelles, pourraient s'ensuivre.
●Le conducteur et tous les passagers à bord du véhicule doivent porter leur
ceinture de sécurité correctement.
Les sacs de sécurité gonflables SRS sont des dispositifs de protection
complémentaires aux ceintures de sécurité.
●Le sac de sécurité gonflable SRS conducteur se déploie avec une violence
considérable, qui peut être très dangereuse voire mortelle si le conducteur se
trouve très près du sac de sécurité gonflable. L'autorité fédérale chargée de la
sécurité routière aux États-Unis, la NHTSA (National Highway Traffic Safety
Administration) conseille:
La zone à risque du sac de sécurité gonflable conducteur se situant dans les
premiers 2 à 3 in. (50 - 75 mm) de déploiement, vous disposez d'une marge de
sécurité confortable en vous plaçant à 10 in. (250 mm) de votre sac de sécurité
gonflable conducteur. Cette distance est à mesurer entre le moyeu du volant de
direction et le sternum. Si vous êtes assis à moins de 10 in. (250 mm), vous
pouvez changer votre position de conduite de plusieurs façons:
Reculez votre siège le plus possible, tout en continuant à pouvoir atteindreconfortablement les pédales.
Inclinez légèrement le dossier du siège. Bien que les véhicules puissent être différents les uns des autres, la plupart
des conducteurs peuvent s'asseoir à une distance de 10 in. (250 mm), même
avec le siège conducteur complètement avancé, simplement en inclinant un
peu le dossier de siège. Si vous avez des difficultés à voir la route après avoir
incliné votre siège, utilisez un coussin ferme et antidérapant pour vous
rehausser ou, si votre véhicule est équipé du réglage en hauteur du siège,
remontez-le.
Si votre volant de direction est réglable, inclinez-le vers le bas. Cela a pour effet d'orienter le sac de sécurité gonflable en direction de votre poitrine
plutôt que de votre tête et de votre cou.
Réglez votre siège selon ces recommandations de la NHTSA, tout en conservant le
contrôle des pédales, du volant de direction et la vue des commandes du tableau
de bord.

ATTENTION
■Précautions avec les sacs de sécurité gonflables SRS
●Attachez correctement votre ceinture de sécurité.
●Si une housse en vinyle recouvre la partie où le sac de sécurité gonflable SRS de
genoux se déploie, veillez à l'enlever.
●Ne pas recouvrir la ceinture de sécurité d'une housse ni d'aucune autre
protection dans sa partie où le sac de sécurité gonflable de ceinture de sécurité
SRS se déploie.
●Ne pas faire subir de chocs ou de pressions excessives aux parties renfermant les
composants des sacs de sécurité gonflables SRS, illustrées P. 63.
En effet, cela pourrait entraîner un fonctionnement anormal des sacs de sécurité
gonflables SRS.
●Ne touchez aucun composant du système immédiatement après le
déclenchement (déploiement) des sacs de sécurité gonflables SRS, car ils sont
alors encore très chauds.
●Si vous avez des difficultés à respirer après le déploiement d'un sac de sécurité
gonflable SRS, ouvrez une porte ou une vitre pour faire entrer de l'air frais, ou
bien descendez du véhicule si cela ne présente pas de danger. Essuyez tout
résidu dès que possible afin d'éviter d'éventuelles irritations de la peau.
●Si les parties renfermant les sacs de sécurité gonflables SRS, telles que la
garniture centrale du volant de direction et/ou la ceinture de sécurité,
apparaissent abîmées ou craquelées, faites-les remplacer par votre
concessionnaire Lexus.
●Ne rien fixer ou disposer sur la planche de
bord, la garniture du volant de direction, la
ceinture de sécurité ou la partie inférieure
du tableau de bord.
Au déploiement des sacs de sécurité
gonflables SRS conducteur, passager, de
ceinture de sécurité et de genoux, tout
objet risque de se transformer en
projectile.
