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.
