When trouble arises
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people. The vehicle may
also lunge forward or lunge back suddenly as it becomes free. Use extreme cau-
tion.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident resulting in death or serious injury.
NOTICE
■To avoid damaging the transmission and other components
●Avoid spinning the rear wheels and depressing the accelerator pedal more than
necessary.
●If the vehicle remains stuck even after these procedures are performed, the vehi-
cle may require towing to be freed.

This information has been prepared in accordance with regulations issued
by the National Highway Traffic Safety Administration of the U.S. Depart-
ment of Transportation.
It provides the purchasers and/or prospective purchasers of Lexus vehi-
cles with information on uniform tire quality grading.
Your Lexus dealer will help answer any questions you may have as you read this
information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found where
applicable on the tire sidewall between tread shoulder and maximum
section width.
For example: Treadwear 200 Traction AA Temperature A
■Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified govern-
ment test course.
For example, a tire graded 150 would wear one and a half (1 - 1 /2) times as well
on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their
use. Performance may differ significantly from the norm due to variations in
driving habits, service practices and differences in road characteristics and cli-
mate.
■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 conditions 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) traction.

For owners
ATTENTION
■Précautions relatives aux coussins gonflables SRS
●Ne laissez pas un enfant se tenir face au
coussin gonflable SRS du passager avant ni
s’asseoir sur les genoux d’un passager
avant.
●Ne laissez pas les occupants du siège avant
tenir des objets sur leurs genoux.
●Ne vous appuyez pas sur la portière ou sur
le brancard de pavillon, ni sur les montants
avant, latéraux ou arrière.
●Ne laissez personne s’agenouiller face à la
portière sur le siège du passager ni sortir la
tête ou les mains à l’extérieur du véhicule.
●Ne fixez et n’appuyez rien sur des zones
telles que la planche de bord, le tampon de
volant, la partie inférieure du tableau de
bord et la porte de la boîte à gants.
Ces objets peuvent se transformer en pro-
jectiles lorsque les coussins gonflables SRS
du conducteur, du passager avant ou de
protection des genoux se déploient.
●Ne fixez rien sur les portières, le pare-brise,
les glaces latérales, les montants avant ou
arrière, le brancard de pavillon et la poi-

ATTENTION
■Précautions relatives aux coussins gonflables SRS
●N’accrochez pas de cintres ni d’objets rigides sur les crochets porte-vêtements.
Tous ces objets pourraient se transformer en projectiles et vous occasionner des
blessures graves, voire mortelles, en cas de déploiement des coussins gonflables
SRS en rideau.
●Si un recouvrement de vinyle est placé sur la zone de déploiement du coussin
SRS de protection des genoux, veillez à le retirer.
●N’utilisez pas d’accessoires recouvrant les parties du siège où les coussins gon-
flables SRS latéraux se déploient, car ceux-ci pourraient nuire au déploiement de
ces coussins. De tels accessoires peuvent empêcher les coussins gonflables
latéraux de se déployer correctement, rendre le système inopérant ou provoquer
accidentellement le déploiement des coussins gonflables latéraux, occasionnant
des blessures graves, voire mortelles.
●Ne frappez pas et n’appliquez pas une pression importante à l’emplacement des
composants de coussins gonflables SRS.
Vous risquez de provoquer un mauvais fonctionnement des coussins gonflables
SRS.
●Ne touchez à aucun composant des coussins gonflables SRS immédiatement
après leur déploiement (gonflage), car ils pourraient être chauds.
●Si vous avez de la difficulté à respirer après le déploiement des coussins gon-
flables SRS, ouvrez une portière ou une glace pour laisser entrer l’air, ou quittez
le véhicule si vous pouvez le faire en toute sécurité. Dès que possible, nettoyez
tous les résidus afin d’éviter les irritations cutanées.
●Si les emplacements de stockage des coussins gonflables SRS, notamment le
tampon de volant, la porte de la boîte à gants et les garnitures des montants avant
et arrière, sont endommagés ou fissurés, faites-les remplacer par votre conces-
sionnaire Lexus.
