When trouble arises
1 Stop the EV system. Set the
parking brake and shift the
shift position to P.
2 Remove the mud, snow or
sand from around the stuck
tire.
3 Place wood, stones or some
other material under the front
wheels to help provide trac-
tion.
4 Restart the EV system
5 Shift the shift position to D or
R and release the parking
brake. Then, while exercising
caution, depress the acceler-
ator pedal.
■When it is difficult to free the
vehicle
Press to turn off TRAC.
(  P.388)
WARNING
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler)
away from the fan. Failure to do
so may cause the hands or
clothing to be caught, resulting
in serious injury.
●Do not loosen the coolant reser-
voir cap while the EV system
and radiator are hot. High tem-
perature steam or coolant could
spray out.
NOTICE
■When adding coolant
Add coolant slowly after the EV
system has cooled down suffi-
ciently. Adding cool coolant to a
hot EV system too quickly can
cause damage to the EV system.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust, etc.).
●Do not use water or any other
coolant when refilling coolant.
Also, do not use any additive
agents for the coolant.
If the vehicle becomes
stuck
Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:

tion on uniform tire quality grad-
ing.
Your Toyota 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
Requirements 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 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government 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 perfo rmance 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 climate.
■Traction AA, A, B, C
The traction grades, from high-
est 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 govern-
ment 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 corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory 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 failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause

Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS (ADVANCED AIRBAGS) conçus selon les normes de sécu-
rité américaines applicables aux véhicules à moteur (FMVSS208).
Le boîtier électronique de coussins gonflables (ECU) utilise le s infor-
mations reçues des capteurs, etc. détaillés dans le schéma ci-d es-
sus de composition du système pour commander le déploiement
des coussins gonflables. Ces inf ormations comprennent des infor-
mations sur la gravité de la collision et les occupants. Le déploie-
ment rapide des coussins gonflables est obtenu au moyen d’une
réaction chimique dans les dispositifs pyrotechniques, qui produit un
gaz inoffensif permettant d’amortir le mouvement des occupants.
AVERTISSEMENT
■Précautions avec les couss-
ins gonflables SRS
Respectez les précautions suiva-
ntes concernant les coussins gon-
flables SRS.
À défaut, des blessures graves,
voire mortelles, pourraient
s’ensuivre.
●Le conducteur et tous les pas-
sagers à bord du véhicule
doivent porter leur ceinture de
sécurité correctement.
Les coussins gonflables SRS
sont des disposit ifs de protec-
tion complémentaires aux cein-
tures de sécurité.

AVERTISSEMENT
●N’utilisez pour les sièges aucun
accessoire venant recouvrir les
parties où se déploient les cous-
sins gonflables SRS latéraux,
car il risquerait d’en gêner le
déploiement. De tels acces-
soires peuvent empêcher les
coussins gonflables SRS
latéraux de s’activer correcte-
ment, neutraliser le système ou
provoquer le déploiement acci-
dentel des coussins gonflables
SRS latéraux, provoquant ainsi
des blessures graves, voire
mortelles.
●Ne pas faire subir de chocs vio-
lents ni des pressions exces-
sives aux parties renfermant les
composants des coussins gon-
flables SRS, ni aux portes
avant.
En effet, cela pour rait entraîner
un mauvais fonctionnement des
coussins gonflables SRS.
●Ne touchez auc un composant
du système immédiatement
après le déclenchement
(déploiement) des coussins
gonflables SRS, car ils sont
alors encore très chauds.
●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.
Retirez tout résidu dès que pos-
sible afin d’éviter d’éventuelles
irritations de la peau.
●Si les parties renfermant les
coussins gonflables SRS, par
exemple la garniture centrale du
volant de direction et les garni-
tures des montants avant et
arrière, sont abîmées ou cra-
quelées, faites-les remplacer
par votre concessionnaire Toy-
ota.
●Ne rien poser 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
normalement le poids du pas-
sager. En conséquence, les
coussins gonflables SRS fron-
taux du passager avant peuvent
ne pas se déployer en cas de
collision.
■Modification et élimination en
fin de vie des éléments du
système de coussins gonfla-
bles SRS
Ne mettez pas à la casse votre
véhicule et ne lui apportez aucune
des modifications suivantes sans
consulter votre concessionnaire
Toyota. Les coussins gonflables
SRS peuvent ne pas fonctionner
correctement ou se déployer (se
gonfler) accidentellement, provo-
quant ainsi des blessures graves,
voire mortelles.
●Installation, dépose, démon-
tage et réparations des couss-
ins gonflables SRS
●Réparations, modifications,
démontage ou remplacement
du volant de direction, du tab-
leau de bord, de la planche de
bord, des sièges ou de leur gar-
nissage, des montants avant,
latéraux et arrière, des rails
latéraux de toit, des panneaux
de portes avant, des garnitures
de portes avant ou des haut-
parleurs de portes avant
