(Customizable features: P.622)
●Check if battery-saving mode is
set. If it is set, cancel the function.
( P.205)
●The electronic key function may
have stopped. ( P.205)

does not op erate prop-
erly
If communication between
the electronic key and vehi-
cle is interrupted ( P.205)
or the electronic key cannot

When trouble arises
If you have a set of jumper (or
booster) cables and a second
vehicle with a 12-volt battery,
you can jump start your vehicle
by following the steps below.
1Open the hood ( P.501) and
fuse box cover.
Push claw and to com-
pletely release the lock, and then lift
up the cover.
2 Open the exclusive jump
starting terminal cover.
3 Connect a positive jumper cable clamp to on your vehicle and
connect the clamp on the other end of the positive cable to on
the second vehicle. Then, connect a negative cable clamp to
on the second vehicle and connect the clamp at the other end of
the negative cable to .
Use jumper cables that can reach t he specified terminals and connecting
If the 12-volt battery is
discharged
The following procedures
may be used to start the
hybrid system if the vehi-
cle’s 12-volt battery is dis-
charged.
You can also call your

When trouble arises
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.634)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cl eared. 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 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.588). 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
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 other positions.
In this case, the vehicle can not be
towed without lifting both front
wheels because the front wheels
will be locked.
●Some systems may require initial-
ization. ( P.634)
■When replacing the 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to Europ ean regulations.
●Use a battery that the case size is
same as the previous one (LN1),
20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and
performance rating (CCA) is
equivalent (285A) 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 period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and hybrid system may not be
able to start.
●Use a ventilation type calcium bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt battery without a
handle is used, removal is more
difficult.
●When removing the 12-volt bat-
tery: P.512
●After replacing, firmly attach the
following items to the exhaust hole
