■Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any
of the following situations:
●The shift lever is shifted to P or N
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after the
brake pedal is released
●Engine switch is turned to ACCESSORY
mode or turned off
■Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the engine is
started or just after the vehicle begins to
move. This sound does not indicate that a
malfunction has occurred in any of these
systems.
●Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly
after the ABS is activated.
■Active Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is oper-
ated, operation sounds and vibrations may
be generated from the brake system, but
this is not a malfunction.
■Automatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems w ill be automatically
re-enabled in the following situations:
●When the engine switch is turned off
●If only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, re frain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS system should
return to normal within 10 minutes.
■Operating conditions of Active Corner-
ing Assist
The system operates when the following
occurs.
●TRAC/VSC can operate
●The driver is attempting to accelerate
while turning
●The system detects th at the vehicle is
drifting to the outer side
●The brake pedal is released
■Secondary Collision Brake operating
conditions
The system operates when the SRS airbag
sensor detects a collision while the vehicle
is in motion.
However, the system does not operate in
any of the following situations.
●The vehicle speed is below 6 mph (10
km/h)
●Components are damaged
■Secondary Collision Brake automatic
cancellation
The system is automatically canceled in any
of the following situations.
●The vehicle speed drops below approxi-
mately 6 mph (10 km/h)
●A certain amount of time elapses during
operation

AVERTISSEMENT
• Inclinez légèrement le dossier du siège.
Bien que les véhicules aient une con-
ception différente, un grand nombre
de conducteurs peuvent s'asseoir à
une distance de 10 in. (250 mm),
même avec le siège conducteur com-
plètement avancé, simplement en
inclinant un peu le dossier de siège. Si
vous avez des difficultés à voir la route
après avoir incliné le dossier 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 recomman-
dations de la NHTSA ci-dessus, tout en
conservant le contrôle des pédales, du
volant et la vue des commandes du tab-
leau de bord.
●Si vous attachez une rallonge de cein-
ture de sécurité au x boucles de cein-
ture de sécurité avant, sans l'attacher
au pêne de la ceinture de sécurité, les
coussins gonflables frontaux SRS
déterminent que le conducteur et le
passager avant ont attaché leur cein-
ture de sécurité, bi en que la ceinture
de sécurité ne soit pas attachée. Dans
ce cas, les coussins gonflables frontaux
SRS peuvent ne pas se déployer cor-
rectement en cas de collision, pouvant
occasionner des blessures graves,
voire mortelles. Ve illez à porter la
ceinture de sécurité avec la rallonge
de ceinture de sécurité.
●Le coussin gonflable passager avant
SRS se déploie également avec une
force considérable, pouvant occasion-
ner des blessures graves, voire mor-
telles, si le passager avant se trouve
très près du coussin gonflable. Le
siège du passager avant doit être éloi-
gné le plus possible du coussin gon-
flable en réglant le dossier de siège de
façon à ce que le passager avant soit
assis bien droit dans le siège.

AVERTISSEMENT
●Ne fixez rien et ne posez rien sur des
emplacements tels que la planche de
bord, la garniture du volant et la partie
inférieure du tableau de bord.
Ces éléments peuvent se transformer
en projectiles lorsque les coussins
gonflables conducteur, passager avant
et genoux SRS se déploient.
●Ne fixez rien aux portes, à la vitre du
pare-brise, aux vitres latérales, aux
montants avant et arrière, au rail latéral
de toit et à la poignée de maintien.
●Ne suspendez aucun cintre ou objet
dur aux crochets à vêtements. Tous
ces objets pourraient se transformer
en projectiles et causer des blessures
graves, voire mortelles en cas de
déploiement des coussins gonflables
rideaux SRS.
●Si un cache en vinyle est placé sur la
zone où le coussin gonflable de
genoux SRS se dépl oie, assurez-vous
de le retirer.
●N'utilisez aucun accessoire de siège
recouvrant les zones de déploiement
des coussins gonflables latéraux SRS,
car il risque de gêner le déploiement
des coussins gonflables SRS. De tels
accessoires peuven t empêcher les
coussins gonflables latéraux de
fonctionner correctement, désactiver
le système ou entraîner le déploiement
accidentel des coussins gonflables
latéraux, occasionna nt des blessures
graves, voire mortelles.
●Évitez de faire subir des chocs ou des
pressions excessives aux parties ren-
fermant les composants de coussins
gonflables SRS. En ef fet, cela pourrait
entraîner un dysfonctionnement des
coussins gonflables SRS.
●Ne touchez aucun composant
immédiatement après le déploiement
(gonflage) des coussins gonflables
SRS, car ils peuv ent être chauds.
●Si vous avez des di fficultés 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'éventuelle s irritations de la
peau.
●Si les partie s renfermant les coussins
gonflables SRS, comme les garnitures
du volant et des montants avant et
arrière, sont endommagées ou cra-
quelées, faites-les remplacer par votre
concessionnaire Lexus.
●Ne placez rien sur le siège du pas-
sager 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,
les coussins gonflables frontaux SRS
du passager avant risquent de ne pas
se déployer en cas de collision.
