3747-2. Steps to take in an emergency
battery discharged, be especially
careful when reconnecting the
battery.
WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the battery.
■Battery precautions
The battery contains poisonous
and corrosive acid ic electrolyte,
while related parts contain lead
and lead compounds. Observe
the following precautions when
handling the battery:
●When working with the battery,
always wear safety glasses and
take care not to allow any bat-
tery fluids (acid) to come into
contact with skin, clothing or the
vehicle body.
●Do not lean over the battery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow children near the
battery.
■To prevent damage to the
vehicle
Do not pull- or push-start the vehi-
cle as the three-way catalytic con-
verter may overheat and become
a fire hazard.
NOTICE
■When handling jumper cables
Be careful that the jumper cables
do not become tangled in the
cooling fans or any of the belts
when connecting or disconnecting
them.
■When closing the doors
While pushing the door glass
towards the inside of the vehicle,
slowly close the door.
Because the side window
open/close function linked to door
operation will no t operate, the
window may interfere with the
vehicle body, possibly scratching
both the vehicle body and win-
dow, or even shattering the win-
dow.

3767-2. Steps to take in an emergency
able.
6Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fans operate and to check
for coolant leaks from the
radiator or hoses.
The fans operate w hen the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fans are operating by
checking the fan sound and air flow.
If it is difficult to check these, turn
the air conditioning system on and
off repeatedly. (The fans may not
operate in freezing temperatures.)
7 If the fans are not operating:
Stop the engine immediately
and contact your Toyota
dealer.
If the fans are operating:
Have the vehicle inspected at
the nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf 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 coolant reser-
voir caps while the engine and
radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the
engine has cooled down suffi-
ciently. Adding cool coolant to a
hot engine too quickly can cause
damage to the engine.
■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 any coolant additive.

Vehicle specifications
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 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
heat buildup and possible tire fail-
ure.

AVERTISSEMENT
■Précautions générales con-
cernant le système de couss-
ins gonflables SRS
●Pour obtenir une protection
maximale en cas d’accident, le
conducteur et tous les passag-
ers doivent toujours porter leur
ceinture de sécurité lorsqu’ils
sont dans le véhicule. Les cous-
sins gonflables SRS ne sont
conçus que comme complé-
ments à la protection première
fournie par les ceintures de
sécurité. Ils ne dispensent pas
de la nécessité du port des
ceintures de sécurité. En com-
plément du port des ceintures
de sécurité, ils offrent la meil-
leure protection en cas d’acci-
dent grave.
Ne pas porter la ceinture de sécu-
rité augmente les risques de bles-
sures graves ou mortelles lors
d'un accident, même lorsque le
véhicule est équipé de coussins
gonflables SRS.
Pour les instructions d’utilisation
et les précautions à prendre au
sujet du système de ceintures de
sécurité, reportez-vous à “cein-
tures de sécurité”.
●Les coussins gonflables
latéraux SRS et les coussins
gonflables rideaux SRS ne sont
conçus que comme complé-
ments à la protection première
fournie par la ceinture de sécu-
rité. Ils ne suppriment pas la
nécessité du port des ceintures
de sécurité. Il est également
important de porter une ceinture
de sécurité pour prévenir les
blessures qui peuvent survenir
lorsqu’un occupant n’est pas
assis dans une position droite
correcte.
●Les coussins gonflables SRS se
déploient à une v itesse et avec
une puissance considérables.
Les occupants qui sont mal
assis lorsque le coussin gon-
flable SRS se déploie peuvent
subir des blessures graves.
Parce que le coussin gonflable
SRS a besoin d’un espace suff-
isant pour son déploiement, le
conducteur doit toujours se tenir
droit et bien enfoncé dans le
siège, le plus loin possible du
volant, tout en conservant le
contrôle complet du véhicule, et
le passager avant doit déplacer
son siège vers l’arrière aussi
loin que possible, se tenir droit
et bien en arrière dans le siège.
●Ne vous asseyez pas ou ne
vous penchez pas près des
portes. Les coussins gonflables
latéraux SRS sont logés dans
les deux dossiers des sièges
avant à côté de la porte. Ils
assurent leur protection en se
déployant rapidement en cas de
collision par le côté. Toutefois,
la force de déploiement d’un
coussin gonflable latéral SRS
peut blesser un passager dont
le corps est trop près du cous-
sin gonflable SRS.

AVERTISSEMENT
●Votre véhicule étant équipé de
coussins gonflables rideaux
SRS, ne vous asseyez pas ou
ne vous penchez pas près des
portes. Ne passez pas de par-
ties de votre corps par la vitre.
Les coussins gonflables rideaux
SRS des deux côtés de l’habita-
cle sont logés dans la partie
latérale du toit (entre le montant
avant et un point situé derrière
la vitre de custode arrière). Ils
assurent une protection en se
déployant rapidement en cas de
choc latéral, de retournement
ou de collision frontale décalée.
Toutefois, leur force de déploie-
ment peut blesser un passager
dont le corps est trop près du
coussin gonflable SRS.
●Ne vous asseyez pas et ne
vous penchez pas inutilement
près des coussins gonflables
SRS. Parce que les coussins
gonflables SRS se déploient à
une vitesse considérable et
avec une puissance conçue
pour vous protéger lors de colli-
sions à haute vitesse, la puis-
sance de déploiement d’un
coussin gonflable peut blesser
un occupant dont le corps en
est trop proche.
Il est également important de
porter votre ceinture de sécurité
pour prévenir les blessures qui
peuvent survenir lorsque le
coussin gonflable SRS entre en
contact avec un occupant qui ne
serait pas assis dans la position
adéquate.
Même en étant correctement
positionné, il n’est pas impossi-
ble que l’occupant subisse des
blessures mineures, telles que
des brûlures et des ecchy-
moses sur le visage ou les bras,
en raison de la puissance de
déploiement des coussins gon-
flables SRS.
●Gardez les bras loin des portes
ou de leur garniture interne. Ils
pourraient être blessés en cas
de déploiement d’un coussin
gonflable latéral SRS.
●Ne placez pas d'objets au-des-
sus ou à proximité du cache du
coussin gonflable SRS ou entre
vous et le coussin gonflable
SRS. En cas de déploiement du
coussin gonflable SRS, ces
objets pourraient interférer avec
son fonctionnement correct et
pourraient être propulsés à
l’intérieur du véhicule et causer
des blessures.
■En cas de déploiement d’un
coussin gonflable SRS
●Lorsque le coussin gonflable
SRS se déploie, un peu de
fumée est relâchée. Cette
fumée peut causer des prob-
lèmes respiratoires pour les
personnes ayant des antécé-
dents d'asthme ou des diffi-
cultés à respirer. Si vous ou vos
passagers éprouvez une diffi-
culté à respirer après le déploie-
ment du coussin gonflable SRS,
prenez ou faites-leur prendre
l'air rapidement.
●Un coussin gonflable SRS qui
se déploie libère un gaz chaud.
Les occupants pourraient se
brûler s'ils entrent en contact
direct avec le gaz chaud.
