8-2. Steps to take in an emergency
COROLLA HV_U
8
When trouble arises
recharge the 12-volt battery
of your vehicle.
5 Open and close any of the
doors of your vehicle with the
power switch OFF.
6 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
7 Make sure the “READY” indi-
cator comes on. If the indica-
tor does not come on, contact
your Toyota dealer.
8 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
Once the hybrid system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■
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 stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at your Toyota dealer.
●
Some systems may require initial-
ization. (P.524)
■
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 12-volt battery
The electricity stored 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 automatically while
the hybrid system is operating.)
■
When recharging or replacing
the 12-volt battery
●
In some cases, it 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 system 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.
