doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the EV system of your vehi-
cle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the EV system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the EV system when
the 12-volt battery is dis-
charged
The EV system cannot be started by
push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights, the air
conditioning system, the audio
system, etc. while the EV system
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.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge 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 EV system may be
unable to start. (The 12-volt battery
recharges automatically while the
EV system is operating.)
■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.
●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 c ontrol or the
mechanical key to lock or unlock
the doors.
●The EV system may not start on
the first attempt a fter 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.
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to o ther positions. In
this case, the vehicle cannot be
towed without lifting both front
wheels because the front wheels
will be locked.
●The power back door (if equipped)
