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 [t ire 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 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 and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire trea d 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 re ached 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.

CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the
steam has subsided. The engine compartment may be very hot.
●After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automatically
start, or the cooling fan may suddenly oper ate even if the gasoline engine stops.
Do not touch or approach rotating parts such as the fan, which may lead to fin-
gers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in
serious injury.
NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid syst em has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too quickly can cause da mage to the hybrid
system.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
●Do not loosen the coolant reservoir caps
while the hybrid system and radiator are
hot.
High temperature steam or coolant could
spray out.

5588-1. Specifications
LS600hL_U(OM50E41U)
■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 conditio ns on a specified indoor labora-
tory test wheel.
Sustained high temperature can cause th e material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger car tires
must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated
and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

■Précautions avec les coussins gonflables SRS
Respectez les précautions suivantes avec les coussins gonflables SRS.
Autrement, des blessures graves, voire mortelles, pourraient s’ensuivre.
●Le conducteur et tous les passagers à bord du véhicule doivent porter leur cein-
ture de sécurité correctement.
Les coussins gonflables SRS sont des di spositifs supplémentaires à utiliser avec
les ceintures de sécurité.
●Le coussin gonflable conducteur SRS se déploie avec une violence considérable,
qui peut être très dangereuse, voire mortelle, si le conducteur se trouve très près
du coussin gonflable. La National Highway Traffic Safety Administration
(NHTSA) recommande:
Sachant que la zone de danger pour le coussin gonflable conducteur se trouve
dans les premiers 2 à 3 in. (50 - 75 mm) de déploiement, vous placer à 10 in.
(250 mm) de votre coussin gonflable co nducteur vous garantit une marge de
sécurité suffisante. Cette di stance est à mesurer entre l’axe du volant et le ster-
num. 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, de manière à pouvoir encore atteindre confortablement 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’asse oir 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 est réglable, inclinez-le vers le bas. Cela a pour effet d’orienter le coussin gonflable en direction de votr e poitrine plutôt que de votre tête et
de votre cou.
Réglez votre siège selon ces recommandations de la NHTSA, tout en conser-
vant le contrôle des pédales, du volant et la vue des commandes du tableau de
bord.

ATTENTION
■Précautions avec les coussins gonflables SRS
●Ne suspendez aucun cintre ni objet dur aux crochets à vêtements. En cas de
déploiement des coussins gonflables rideaux SRS, tous ces objets pourraient se
transformer en projectiles et causer des blessures graves, voire mortelles.
●Si un cache en vinyle recouvre la partie où le coussin gonflable de genoux SRS se
déploie, veillez à l’enlever.
●N’utilisez aucun accessoire de siège qui couvrirait les zones de déploiement des
coussins gonflables latéraux SRS et du coussin gonflable d’assise, car il risquerait
de gêner le déploiement. De tels accessoires peuvent empêcher les coussins
gonflables latéraux et le coussin gonflabl e d’assise de fonctionner correctement,
désactiver le dispositif ou entraîner le déploiement accidentel des coussins gon-
flables latéraux et du coussin gonflable d’assise, entraînant la mort ou des
blessures graves.
●Évitez de faire subir des chocs ou des pressions excessives aux zones renfermant
les composants des coussins gonflables SRS. En effet, cela pourrait entraîner un
fonctionnement anormal des coussins gonflables SRS.
●Ne touchez aucun composant du système immédiatement après le déploiement
(gonflage) des coussins gonflables SRS, car ils peuvent être chauds.
●Si vous avez des difficultés à respirer après le déploiement des coussins gon-
flables 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 le s coussins gonflables SRS, telles que la garniture du
moyeu de volant et les garnitures de montants avant et arrière, apparaissent
abîmées ou craquelées, faites-les remplacer par votre concessionnaire Lexus.
●Ne placez rien sur le siège du passager avant, comme un coussin par exemple.
Cela a pour conséque nce de répartir le poids du passager sur toute la surface du
siège, ce qui empêche le capteur de détecter correctement le poids du passager.
En conséquence, le coussin gonflable pa ssager avant SRS risque de ne pas se
déployer en cas de choc.
