8005-2. Steps to take in an emergency
Add coolant if necessary.
(
 P. 6 7 1 )
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans op erate and to check for coolant
leaks from the radiator or hoses. The fans operate when the air conditio ning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking
the fan sound and air flow. If it is diff icult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.STEP 5
CAUTION■
To prevent an accident or injury when in specting under the hood of your vehicle●
If steam is seen coming from under the hood, do not open the hood until the
steam has subsided. The engine compartm ent may be very hot, causing serious
injuries such as burns.●
Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fans
and belts. Failure to do so may cause the hands or clothing to be caught, resulting
in serious injury.
●
Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may resu lt from hot coolant and steam released
under pressure.STEP 6

Vehicle specifications ■ Temperature A, B, C
The temperature grades are A (the hi ghest), 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. 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 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 build up 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 les passagers du véhicule doivent porter correctement leur
ceinture de sécurité.
Les coussins gonflables SRS sont des dispositifs supplémentaires à utiliser avec
les ceintures de sécurité.●
Le coussin gonflable SRS conducteur se déploie avec une violence considérable,
qui peut être très dangereuse, voire mortelle, si le conducteur se trouve très près
du coussin 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 coussin gonflable conducteur se situant dans les premiers 2 à
3 in. (50 - 75 mm) de déploiement, placez-vous à 10 in. (250 mm) de votre
coussin gonflable conducteur vous garantit une marge de sécurité suffisante.
Cette distance est à mesurer entre l’axe du volant 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, 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’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 est réglable, inclinez-le vers le bas. Cela a pour effet d’orienter
le coussins gonflables 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 et la vue des commandes du tableau de bord.

For owners ATTENTION■
Précautions avec les coussins gonflables SRS ●
Si vous avez des difficultés à respirer après le déploiement des coussins
gonflables 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 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 conséquence 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 SRS du passager avant risque de ne pas se
déployer en cas de choc.
