When trouble arises
WARNING
As an added safety feature, your
vehicle has been equipped with a
tire pressure m onitoring system
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) when one or more
of your tires is significantly
under-inflated. Accordingly, when
the low tire pressure telltale (tire
pressure warning light) illumi-
nates, you should stop and check
your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a signifi-
cantly under-inflated tire causes
the tire to overheat and can lead
to tire failure. Under-inflation also
reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for pro per tire mainte-
nance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-infla-
tion has not reach ed the level to
trigger illumination of the TPMS
low tire pressure telltale (tire pres-
sure warning light).
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not operating properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the te lltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be ab le to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.

power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
●The power back door must be ini-
tialized. (P.138)
■When replacing the 12-volt bat-
tery
●Use a Central De gassing type
12-volt battery (European Regula-
tions).
●Use a 12-volt battery that the case
size is same as the previous one
(LN2), 20 hour rate capacity
(20HR) is equiva lent (55Ah) or
greater, and performance rating
(CCA) is equivalent (345A) or
greater.
• If the sizes differ, the 12-volt bat-
tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and the hybrid system may not be
able to start.
●Use a 12-volt battery with a han-
dle. If a 12-volt b attery without a
handle is used, removal is more
difficult.
●After replacing, firmly attach the
following items to the exhaust hole
of the 12-volt battery.
• Use the exhaust hose that was attached to the 12-volt battery
before replacing an d confirm that
it is firmly connected to the hole
section of t he vehicle.
• Use the exhaust hole plug included with the 12-volt battery
replaced or the one installed on
the 12-volt battery prior to the
replacement. (Depending on the
12-volt battery to be replaced, the
exhaust hole may be plugged.) Exhaust hole

WARNING
■When removing the 12-volt
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, leading to a fire
in addition to ele ctrical shocks
and death or serious injury.
■When disconnecting the
12-volt battery
Do not disconnect the negative (-)
terminal on the body side. The
disconnected negative (-) terminal
may touch the positive (+) termi-
nal, which may cause a short and
result in death or serious injury.

When trouble arises
However, if the message appears
again frequently, contact your Toy-
ota 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.
●After the hybrid system has
been turned off, check that the
“READY” indicator is off.
When the hybrid system is oper-
ating, the gasoline engine may
automatically start, or the cool-
ing fan may suddenly operate
even if the gasoline engine
stops. Do not touch or approach
rotating parts such as the fan,
which may lead to fingers or
clothing (especially a tie, a scarf
or a muffler) getting caught,
resulting in serious injury.
●Do not loosen the radiator cap
and the coolant reservoir caps
while the hybrid system and
radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine/power
control unit coolant
Add coolant slowly after the
hybrid system has cooled down
sufficiently. Adding cool coolant to
a hot hybrid system too quickly
can cause damage to the hybrid
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 any coolant additive.

Ensemble de capteurs de coussins gonflables
Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS conçus selon les normes de sécurité américaines applica-
bles aux véhicules à moteur (FMVSS208). L'ensemble de capteurs
de coussins gonflables (ECU) régule le déploiement des coussins
gonflables sur la base des informa tions qu'il reçoit des capteurs,
etc., indiqués ci-dessus dans le schéma illustrant les composants du
système. Parmi ces informations figurent la gravité du choc et l'occu-
pation du véhicule par les passagers. Le déploiement rapide des
coussins gonflables est obtenu au moyen d'une réaction chimique
dans les dispositifs pyrotechniques, qui produit un gaz inoffen sif per-
mettant d'amortir le mouvement des occupants.
AVERTISSEMENT
■Précautions relatives aux
coussins gonflables SRS
Respectez les précautions suiva-
ntes concernant les coussins gon-
flables SRS.
Le non-respect de ces précau-
tions peut occasionner des bless-
ures graves, voire mortelles.
●Le conducteur et tous les pas-
sagers du véhicule doivent por-
ter correctement leur ceinture
de sécurité.
Les coussins gonflables SRS
sont des disposit ifs supplémen-
taires à utiliser avec les cein-
tures de sécurité.
●Le coussin gonflable conduc-
teur SRS se déploie avec une
force considérable, pouvant
occasionner des blessures
graves, voire mortelles, si le
conducteur se trouve très près
du coussin gonflable. L'autorité
fédérale chargée de la sécurité
routière aux États-Unis
(NHTSA) conseille:
La zone à risque du coussin
gonflable conducteur se situant
dans les premiers 2 à 3 in. (50 à
75 mm) de déploiement, vous
placer à 10 in. (250 mm) de
votre coussin gonflable conduc-
teur vous garantit une marge de
sécurité suffisante. Cette dis-
tance est à mesurer entre le
centre du volant et le sternum.
Si vous êtes assis à moins de
10 in. (250 mm), vous pouvez
changer votre position de con-
duite de plusieurs façons:
• Reculez votre siège le plus pos- sible, de manière à pouvoir
encore atteindre confortable-
ment les pédales.
