2020 TOYOTA HIGHLANDER HYBRID ECU

4947-2. Steps to take in an emergency
HIGHLANDER HV_U
■Starting the hybrid system
when the 12-volt battery is dis-
charged
The hybrid system cannot be started
by push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stor ed in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.538)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges aut omatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery
●In some cases, i t may not be pos-
sible to unlock the doors using the
smart key system when the 12-volt battery is
discharged. Use
the wireless remote control or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attempt after the
12-volt battery has recharged but
will start normally after the second
attempt. This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the
12-volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
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.141)
■When replacing t he 12-volt bat-
tery
●Use a Central Degassing 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 equivalent (55Ah) or
greater, and per formance 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 p eriod 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 battery 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.

HIGHLANDER HV_U
WA R N I N G
●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 12-volt battery sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow child ren near the
12-volt battery.
■After recharging the 12-volt
battery
Have the 12-volt battery
inspected at your Toyota dealer
as soon as possible.
If the 12-volt battery is deteriorat-
ing, continued use may cause the
12-volt battery to emit a malodor-
ous gas, which may be detrimen-
tal to the health of passengers.
■When replacing the 12-volt
battery
●When the vent plug and indica-
tor are close to the hold down
clamp, the battery fluid (sulfuric
acid) may leak.
●For information regarding
12-volt battery replacement,
contact your Toyota dealer.
●After replacing, securely attach
the exhaust hose and exhaust
hole plug to the exhaust hole of
the replaced 12-volt battery. If
not properly installed, gases
(hydrogen) may leak into the
vehicle interior, and there is the
possible danger of the gas ignit-
ing and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan or belt.
■To prevent damaging the
vehicle
The exclusive jump starting termi-
nal is to be used when charging
the 12-volt battery from another
vehicle in an emergency. It cannot
be used to jump start another
vehicle.

■Détérioration et usure des
ceintures de sécurité
Inspectez le système de ceintures
de sécurité régulièrement. Con-
trôlez l'absence de coupures,
d'effilochages et de pièces
desserrées. N'utilisez pas une
ceinture de sécurité endommagée
avant qu'elle ne soit remplacée.
Une ceinture de sécurité endom-
magée ne permet pas de protéger

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 (FM VSS208). 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 pass agers. 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.

■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 atteindr e confortable-
ment les pédales.
