One of the following may be the
cause of the problem:
The AC charging cable may
be attached to the vehicle.
( P.121)
 The electronic key may not be
functioning properly.
( P.567)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle. ( P.332)
 There may be a malfunction

a blown fuse. However,
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. ( P.565)
NOTICE
■Be careful when driving over
bumps with the compact
spare tire installed on the
vehicle
The vehicle height may become
lower when driving with the com-
pact spare tire compared to when
driving with standard tires. Be
careful when driving over uneven
road surfaces.
■Driving with tire chains and
the compact spare tire
Do not fit tire chains to the com-
pact spare tire.
Tire chains may damage the vehi-
cle body and adversely affect driv-
ing performance.
■When replacing the tires
(vehicles with tire pressure
warning system)
When removing or fitting the
wheels, tires or the tire pressure
warning valve and transmitter,
contact your Toyota dealer as the
tire pressure warning valve and
transmitter may be damaged if not

When trouble arises
recharge the 12-volt battery
of your vehicle.
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 light 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.
9 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.
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-vol t battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary 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 you r Toyota dealer.
●Some systems may require initial-
ization. (P.615)
■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-vo lt battery termi-
nals, contact your Toyota dealer.
■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 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 c ontrol or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attemp t after reinstall-
ing the 12-volt battery. In that
case, start the hybrid system in
the same manner as when the
electronic key does not operate
properly ( P.568). This is not a
malfunction, as the hybrid system
will start normally on the second
attempt.
●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
