WARNING
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possibl e, and then immediately consult a
doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persi sts, consult a doctor.
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediate ly
after the vehicle has been driven.
After the vehicle has been driven, the wheels and the area arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on the vehi-
cle.
●If the hose is not properly connected to the valve, air leakage may
occur or sealant may be sprayed out.
●Follow the operation procedure to repair the tire. If the proce dures are
not followed, the sealant may spray out.
●If the hose comes off the valve while inflating the tire, there is a risk
that the hose will mo ve abruptly due to air pressure.
●After inflation of the tire has completed, the sealant may spla tter when
the hose is disconnec ted or some air is let out of the tire.
●Keep back from the tire while it is being repaired, as there is a chance
of it bursting while the repair operation is being performed. I f you
notice any cracks or deformation of the tire, turn off the comp ressor
switch and stop the repair operation immediately.
●The repair kit may overheat if operated for a long period of ti me. Do not
operate the repair kit continuous ly for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the met al part
connecting the bottle and the compressor. I t will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than
the one indicated. If the sticker is attached to an area where an SRS
airbag is located, such as the pad of the steering wheel, it ma y prevent
the SRS airbag from operating properly.

WARNING
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic ele ctrolyte,
while related parts contain lead and lead compounds. Observe th e following
precautions when handling the 12-volt battery:
● When working with the 12-volt battery, always wear safety glass es and
take care not to allow any 12-volt battery fluids (acid) to come into contact
with skin, clothing or the vehicle body.
● Do not lean over the 12-volt battery.
● In the event that 12-volt battery fluid comes into contact with the skin or
eyes, immediately wash the affected area with water and seek me dical
attention.
Place a wet sponge or cloth over the affected area until medica l attention
can be received.
● Always wash your hands after handling the 12-volt battery suppo rt, termi-
nals, and other battery-related parts.
● Do not allow children near the 12-volt battery.
■ After recharging the 12-volt battery
Have the 12-volt battery inspected at your Toyota dealer as soo n as possi-
ble.
If the 12-volt battery is deteriorating, continued use may caus e the 12-volt
battery to emit a malodorous gas, which may be detrimental to the health of
passengers.
■ When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug
to the exhaust hole of the exchanged 12-volt battery. If not pr operly
installed, gases (hydrogen) may leak into the vehicle interior, and there is
the possible danger of the gas igniting and exploding.
■ When replacing the 12-volt battery
 P. 376
NOTICE
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when chargin g the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.
■ When handling jumper cables
When connecting the jumper cables, ensure that they do not beco me entan-
gled in the cooling fans.

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 les informa-
tions reçues des capteurs, etc. détaillés dans le schéma ci-des sus de
composition du système pour commander le déploiement des couss-
ins gonflables. Ces informations comprennent des informations s ur la
gravité de la collision et les o ccupants. Le déploiement rapide des
coussins gonflables est obtenu au moyen d’une réaction chimique
dans les dispositifs py rotechniques, qui produit un gaz inoffen sif per-
mettant d’amortir le mo uvement des occupants.
