WARNING
■While towing
●When towing using cables or
chains, avoid sudden starts,
etc., which place excessive
stress on the towing eyelets,
cables or chains. The towing
eyelets, cables or chains may
become damaged, broken
debris may hit people, and
cause serious damage.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the front
wheels and possibly leading to
an accident resulting in death or
serious injury:
• Unfasten the driver’s seat belt and open the driver’s door.
• Turn the power switch off.
■Installing towi ng eyelets to
the vehicle
Make sure that towing eyelets are
installed securely. If not securely
installed, towing eyelets may
come loose during towing.
NOTICE
■To prevent damage to the
vehicle during emergency
towing
Do not secure cables or chains to
the suspension components.
If you think something
is wrong
If you notice any of the fol-
lowing symptoms, your
vehicle probably needs
adjustment or repair. Con-
tact your Toyota dealer as
soon as possible.

When trouble arises
6 Open and close any of the
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)
