■Stopping the hybrid system
Shift the shift lever to P, set the parking brake, and press the power switch as you normally
do when stopping the hybrid system.
■Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the electronic
key battery be replaced immediately when the battery is depleted. (P. 630)
■Changing power switch modes
Release the brake pedal and press the power switch in step above.
The hybrid system does not start and modes will be changed each time the switch is
pressed. ( P. 240)
■When the electronic key does not work properly
●Make sure that the smart access system wi th push-button start has not been deacti-
vated in the customization setting. If it is off, turn the function on.
(Customizable features P. 740)
●Check if battery-saving mode is set. If it is set, cancel the function. (P. 160)
WARNING
■When using the mechanical key and operating the power windows or the moon roof

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value be fore the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme lo ad conditions.
How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.

WARNING
■Cautions during customization
As the hybrid system needs to be operating during customization, ensure that the vehi-
cle is parked in a place with adequate ventil ation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is operating while
customizing features.

For owners
RX450h_RX450hL_U
Votre véhicule est équipé de COUSSINS GONFLABLES INTELLIGENTS
conçus selon les normes de sécurité américaines applicables aux véhicules à
moteur (FMVSS208). L'ensemble de cap teurs de coussins gonflables (ECU)
régule le déploiement des coussins gonfla bles sur la base des informations qu'il
reçoit des capteurs, etc., indiqués ci-de ssus dans le schéma illustrant les compo-
sants du système. Parmi ces informations figurent la gravité du choc et l'occupa-
tion du véhicule par les passagers. Le déploiement rapide des coussins
gonflables est obtenu au moyen d'une réaction chimique dans les dispositifs
pyrotechniques, qui produit un gaz ino ffensif permettant d'amortir le mouve-
ment des occupants.
AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
Respectez les précautions su ivantes concernant les coussins gonflables SRS.
Le non-respect de ces précautions peut oc casionner des blessures graves, voire mor-
telles.
●Le conducteur et tous les passagers du véhicule doivent porter correctement leur
ceinture de sécurité.
Les coussins gonflables SRS sont des disp ositifs supplémentaires à utiliser avec les
ceintures de sécurité.
●Le coussin gonflable conducteur SRS se déploie avec une force considérable, pou-
vant occasionner des blessures graves, voire mortelles, si le conducteur se trouve
très près du coussin gonflable. L'autorité fédérale chargée de la sécurité routière aux
États-Unis (NHTSA) conseille:
La zone à risque du coussin gonflable cond ucteur se situant dans les premiers 2 à 3
in. (50 à 75 mm) de déploiement, vous placer à 10 in. (250 mm) de votre coussin
gonflable conducteur vous garantit une ma rge de sécurité suffisante. Cette distance
est à mesurer entre le centre du volant et le sternum. Si vous êtes assis à moins de 10
in. (250 mm), vous pouvez changer votre po sition 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 aient une conception différente, un grand nombre de
conducteurs peuvent s' asseoir à une distance de 10 in. (250 mm), même avec le
siège conducteur complètement avancé, si mplement en inclinant un peu le dos-
sier de siège. Si vous avez des difficulté s à voir la route après avoir incliné le dos-
sier de votre siège, utilisez un coussin ferme et antidérapant pour vous rehausser
ou remontez le siège si votre véhicule est équipé de cette fonction.
• Si votre volant est réglable, inclinez-le vers le bas. Cela a pour effet d'orienter le
coussin gonflable en direction de votre poitrine plutôt que de votre tête et de votre
cou.
Réglez votre siège selon les recommanda tions de la NHTSA ci-dessus, tout en
conservant le contrôle des pédales, du vo lant et la vue des commandes du tableau
de bord.
